close loop mud system

Recently drilling has been changed a lot, the old experience did not work, people has their own new design. “Zero discharge mud systems” are urgently required because of the environment protection. Auger box, screw conveyor can be used to collect the drilling cuttings from shale shaker, desander, desilter, mud cleaner, dewatering unit and centrifuge, then transfer them to a catch pit for later processing. In some development company where the government did not have strict regulation on environment protection, they even do not use any mud system, and let the drilling fluids discharged directly. They may face big problem in the future.

Dewatering unit is required to work together with the system, it can make further process of the fluids after processed by centrifuge after the well is finished.

The mud tank is designed similar to 40 feet standard container, it is more convenient to transport in any countries in the world. All the lifting device, dimension, skid is same with container, and we put GN solids control equipments on top of it.

1 How to install vibrating motor ?

shale shaker vibrator

 (1). Before installing vibrator, turn off and lock out/tag out all energy sources to mounting structure according to ANSI standards。

(2). If using a cutting torch or welding, test atmosphere for gas level or dust content.

(3). Make sure mounting surface is strong and flat, 0.25 mm acros vibrator feet. (This will minimize internal stress to vibrator casting when tightening mount bolts.

(4) Make sure mounting surface and vibrator are clean and free of debris, paint, and oxidation.

(5) Before installing vibrator onto mount, apply thread sealing compound to all bolts.

(6) After the vibrator has been operated for 10 to 20 minutes, check bolt torque. Tighten if necessary

2 How to  maintain  vibrating motor?

(1)Clean dust on shell regularly

(2)Before operating, must check the bolts to confirm whether there is loose or not. Otherwise, we must screw bolts tight before running shaker

(3) Inspect the cable, whether there is wear, hold down, crushing, etc.

(4) the vibration motor should be under good lubrication during operation:

Motors before fixed on shaker, the bearing is filled with SKF specific lubricate grease, the temperature range is -40 ~ 200℃

During running, every 2000 working hours user should makeup LGHP2 lubricate grease once. Every bearing can not be filled over 25.8g.

To make sure bearing operated well, we must use LGHP2 grade high temperature lubrication grease. Before adding new lubrication grease we should clean the input hole.

GN provide spare parts including vibrating motor for shale shaker, if you need any maintenance suggestion, pls contact GN solids control.

1 shaker deck adjustment

A spring-loaded plunger and reversible pawl provide a ratcheting action during movement of the operating handle. A full 180 degrees of movement is possible in both directions. Depending on pawl setting, moving the handle in one direction turns the jack screw to raise or lower the screen frame, while in the other direction the jack screw remains stationary during handle movement. The spring-loaded pawl permits the operator to switch the direction to either raise or lower the screen frame, as required.The angle of the discharge end of the screen frame is infinitely adjustable within the equipment’s available range.

2 shale shaker maintenance

(1)Inspect discharge duct connection on side of hopper for leaks. Tighten connection and/or add silicone sealant to prevent leakage.

(2)Inspect cover on unused hopper discharge connection for leaks. Tighten connection and/or add silicone sealant to prevent leakage.

(3)Using a water hose, wash off accumulated process material from screen frame, interior of hopper and AWD angle adjustment components.

(4)Excess process material in these areas may impede angle adjustment of screen frame and can reduce screen frame vibration if the frame bottoms out on the buildup.

(5)Check for and remove any accumulation of process material or other obstruction in feeder interior. Feeder blockage may cause excessive splashing and uneven distribution of slurry onto the screen bed.

(6) Inspect entire machine for evidence of coating damage, including exposed base metal, corrosion, deep scratches, or other voids. Repair damaged areas in accordance with coating manufacturers’ specifications.

For trouble shootings of linear motion shale shaker, pls contact GN solids control.

Rotary rigs drill the vast majority of wells today, including all medium and deep wells. The rotary rig consists of four major systems. These include the engines, and the hoisting, rotating, and mud systems.

rotary rig equipments

General of drilling mud(drilling fluids)

Common drilling mud is made of bentonite clay. A heavier drilling mud can be made by adding barite. Various chemicals are also used in different situations. The drilling mud liquid is usually water but is sometimes oil-based. Drilling mud are described by weight. Water weighs 8.3 pounds per gallon. Average bentonite drilling mud weighs from 9 to 10 ppg. Heavy drilling mud weighs from 15 to 20 pounds per gallon. The heavier the drilling mud, the greater the pressure it exerts on the bottom of the well.

Fluid is circulated while the drilling proceeds. Powerful pumps move the fluid down to the pipe, through the bit and back to the surface, carrying the cuttings and other debris with it. Thus, on a rotary rig , drilling can be continuous as stopping to bail the cuttings is no longer required.  The drilling mud also stabilizes the walls of the hole.

Mud circulation system for rotary rig

Drilling mud is stored in steel mud pits beside the rig. The drilling mud then flows down through the hollow rotating drill string and jets out through holes in the drilling bit on the bottom of the well. The drilling mud picks cuttings from the bottom of the well. It flows up the well in the space between the rotating drill string and well walls.

Drilling mud serves several purposes. The mud removes cuttings from the bottom of the well. As the mud flows across the bit, it cleans cuttings from the teeth. The drilling mud cools the bit from heat generated by the friction of drilling. The drilling mud also controls pressures in the well and prevents blowouts.

GN solids control have designed and manufactured many sets of mud circulation system for rotary rig, both for oil & gas drilling and workover operation. From 250HP to 3000HP land rig, we can provide customized solution for land rig drilling.

Main features of 150gpm portable mud cleaning system

1

hydraulic lift mud system

 Compact structure, convenient for transportation and operation.

Folded for transport Dimension: LxWxH=4000x2400x3800mm, the user did not need to disassembly any equipments or parts, just fold the walkway and hand rail to the tank before transportation from one site to another. It is very convenient.

2 Separation Point:20Microns

3 Nominal Handing capacity: 100GPM.

 How do 150gpm portable mud cleaning system work?

A: 50YZ40-10 Submersible slurry pump suck mud from the mud pit and feed to GNZS85-2 Shale shaker from the backside buffer box.

B:Shale Shaker first panel fixed with API 60 screen. Fluids from the slurry pump will flow to screens for solids screening. Fluids with particles only smaller then 250microns will go to tank 1# Compartment.

C:Shale Shaker second screen panel fixed with API 120 screen. SB3×2-12 Centrifugal pump will suck fluids from 1# Compartment and feed to 2x4inch desilter cones.The dirty mud will drops down to second screen panel for drying from the cones nipple,the cleaning fluids with particles under 20microns overflow from desilter pipe to the 2# compartment.

D:2# compartment fluids with 20microns solids separated can be feed to mud pump for drilling .

New development of GN

1 now we have a new mud cleaner to replace the shale shaker and desilter, it is with more compact structure than 2 equipments, its function equal to shale shaker and desilter, and large capacity shaker can process the drilling fluids drier, the separated solids can be shipped directly by the trailer.

2 now we have hydraulic lift mud system in production, if it is not convenient to rent a crane in the drilling site, the user can use the hydraulic lift device to lift the mud system first, then use the trailer to transport it directly.

For more information of GN mud cleaning system, whatever trailer mounted , hydraulic lift or diesel oil generator drived, welcome to contact GN sales.

drilling cutting management

The first step in managing drilling wastes is to separate the solid cuttings from the liquid drilling mud. Once solid and liquid drilling wastes have been separated, companies can use a variety of technologies and practices to manage the wastes. For some applications, drilling wastes are solidified or stabilized prior to their ultimate management practice. The management technologies and practices can be grouped into three major categories: waste minimization, recycle/reuse, and disposal.

GN solids control equipments can make the first step of solids control, to clean the drilling mud and reuse for drilling rig.

If the solids collected by the shale shakers are still coated with so much mud that they are unsuitable for the next reuse or disposal step or if the used mud is valuable enough to collect as much of it as possible, the solids can be further treated with drying shakers utilizing high gravitational separation, vertical or horizontal rotary cuttings dryers, screw-type squeeze presses, or centrifuges. The cuttings dryers recover additional mud and produce dry, powdery cuttings.

Our equipments can do a series job for drilling cuttings management, firstly we use high G shaker to dry the drilling cuttings and recycle a small part of the drilling fluids for re-use. Most of the drilling cuttings are dried and transferred to vertical cutting dryer by screw conveyor. The dry the drilling cutting is, the better performance can reach by the cutting dryer.

After processed by vertical cutting dryer, the large solids are separated out, and sent to Cement Plant or brickyard or used for construction industry. The separated fluids are pumped by screw pump to a high speed centrifuge for further process. Finally the clean mud can be re-used for drilling rig or re-used to make new mud.

Following is the ways can reuse the drilling waste.

drilling waste management

 l  Recycling Muds

l  Roadspreading

l  Reuse of Cuttings for Construction Purposes

l  Restoration of Wetlands Using Cuttings

l  Use of Oily Cuttings as Fuel

 We have a standard system for onshore and offshore drilling waste management, and we have enough knowledge for the features of onshore and offshore drilling mud, welcome to communicate with us for the detailed proposal.
