Drilling mud cleaning system for HDD and oil well

The drilling mud cleaning system are required in oil well drilling,horizontal drilling,the mud cleaning system fuction is for preparing clean mud for drilling rig.

Generally,The mud cleaning system for removal of drill cuttings and recovery of drilling mud coming from an oil well, where the mud slurry may be made up essentially of barite particles having a specific gravity of 4.2 or more and a particle size mostly under 200 mesh, drill cuttings having a specific gravity of 2-3, and varying particle sizes ranging from 200 mesh to 1/2 inch or more, and water;

  • In oil well drilling, drilling mud must be supplied to the hole as the well depth progresses. One of the basic functions of drilling mud is to carry the drill cuttings up to the surface so they can be disposed of. A drilling mud in common use today is typically composed of barite and water. There may be other constituents, (such as oil) but they would exist only in small amounts or percentages. Since large quantities of drilling mud are needed in drilling an oil well, it is desirable to recover the barite, and recycle it. Various drilling mud cleaning systems are in use today for separating the drill cuttings from the slurry so that the fluid and/or barite can be recycled. Most systems use a combination of one or more screens or sieves in a series flow relationship, with a final separating step using a hydrocyclone or centrifuge. Hydrocyclones desander and decanting centrifuges are expensive pieces of equipment with high energy and maintenance costs.
  • In HDD drilling mud cleaning system,sometimes there is a single tank, closed-loop system or a multi-tank mud system is required, GN Solids Control can develop the proper system to meet specific requirements. from small HDD (hirontal directional drilling mud system) to deep oil well drilling mud system.

Oil well Drilling mud (fluids) Conditioner

Oil well drilling mud conditioner are manufactured in our China factory.We provide you with competitive price,best solutions for drilling mud condition.

The present invention relates to additives or conditioners for oil well drilling fluids, and more particularly to a boron-chrome lignosulfonate drilling fluid additive or mud conditioner.

GN Solids Control design and manufacture Drilling Mud Conditioner utilizes a combination of hydro cyclones and a linear motion shale shaker to separate solids from liquid. The combination of hydrocyclone cones utilized is dependent upon the specific application of duty. Cone combinations typically consist of a few desander cones (10-inch or 12-inch) and several desilter cones (4-inch).

The most commonly used drilling fluids are aqueous dispersions of clay. The drilling fluid or “mud” is pumped down a hollow drill string, through the bit at the bottom, and up the annulus formed by the hole or casing and the drill string to thesurface. After reaching the surface, various operations are performed on the drilling fluid to remove the cuttings and formation material thereform. The drilling fluid is then treated with additives to obtain a desired set of rheological properties,and is then pumped back into the well in a continuous circulating process.

A satisfactory drilling fluid must have various desired functions, such as gelling during temporary work stoppage and other functions well known in the art, which contribute to the success of the well drilling operation. In order to accomplishthese various functions, it has been found necessary to incorporate certain additives in the drilling fluid. Modified lignosulfonates derived from spent sulfite liquor obtained from the pulping of woods have proven to be effective additives forobtaining the desired properties in drilling fluids.

These cones are mounted above the screen deck of the linear motion  shale shaker. The mud is fed first through the hydrocyclones, where it subsequently cascades down over the shale shaker. The remaining solids, including barite, are returned to the active drilling mud system.

The screens used on the shale shaker determine the cut point for the mud conditioner unit. When weighted mud  are used, shaker screens are selected in a manner that ensures that the majority of the weight material is returned to the mud system. Typically, API 170 screens (>82.5 to 98.0 microns) are utilized to reduce the amount of weight material discarded by the screens.

Drilling mud conditioner are widely used in petroleum oil and gas exploration industry, no-dig engineering, geotechnical engineering, mine, metallurgy, coal, hydropower and many other industries.GN drilling mud conditioning equipment can be used in both onshore and offshore oilfield project.HDD Horinzontal directional drilling mud system

Now I share the history of oil well drilling history with you:

The earliest known oil wells were drilled in China in 347 CE. They had depths of up to about 800 feet (240 m) and were drilled using bits attached to bamboo poles.[1] The oil was burned to evaporate brine and produce salt. By the 10th century, extensive bamboo pipelines connected oil wells with salt springs. The ancient records of China and Japan are said to contain many allusions to the use of natural gas for lighting and heating. Petroleum was known as burning water in Japan in the 7th century.[2]

the Middle East’s petroleum industry was established by the 8th century, when the streets of the newly constructed Baghdad were paved with tar, derived from petroleum that became accessible from natural fields in the region. Petroleum was distilled by the Persian alchemist Muhammad ibn Zakarīya Rāzi (Rhazes) in the 9th century, producing chemicals such as kerosene in the alembic (al-ambiq),[3] and which was mainly used for kerosene lamps.[4] Arab and Persian chemists also distilled crude oil in order to produce flammable products for military purposes. Through Islamic Spain, distillation became available in Western Europe by the 12th century.
