Oil Well Choke & Kill Manifold manufacturer

Oil Well Choke & Kill Manifold are a kind of well-control equipments, GN solids control do not produce such equipments, our products range including a complete set of solids control equipments and mud tanks.

An arrangement of piping or valves designed to control, distribute and often monitor fluid flow. Manifolds are often configured for specific functions, such as a choke manifold used in well-control operations and a squeeze manifold used in squeeze-cementing work. In each case, the functional requirements of the operation have been addressed in the configuration of the manifold and the degree of control and instrumentation required.

Chock Manifold

choke manifold
choke manifold

Oil well choke manifold is high-pressure pipe leading from an outlet on the BOP stack to the backpressure choke and associated manifold. During well-control operations, the fluid under pressure in the wellbore flows out of the well through the choke line to the choke, reducing the fluid pressure to atmospheric pressure. In floating offshore operations, the choke and kill lines exit the subsea BOP stack and then run along the outside of the drilling riser to the surface.

A choke manifold is used to lower the pressure from the well head. It consists of a set of high pressure valves and at least two chokes. These chokes can be fixed or adjustable or a mix of both. The redundancy is needed so that if one choke has to be taken out of service, the flow can be directed through another one. these long choke and kill lines must be considered to control the well properly.

(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.

Shale shaker operation and maintenance

GNZS703 shale shaker is widely used for oil and gas drilling and directional drilling in the world.

1 shaker deck adjustment

LMSS
LMSS

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.

agitator mixer
agitator mixer

Because of the long distance shipment from China to Latin America, and the high import tax of mud tank, the economic way is to make the tank by local mud tank manufacture and installed with GN equipments. We will have a technician for instruction of installation.

Agitator mixer uses an impeller to mix and suspend the solids using both axial and radial flows, and by utilizing low shear mixers to suspend and mix mud additives particle size degradation and polymer shear. Unlike centrifugal pumps or mud guns. The Mud Agitator is relatively low shear and low energy device, so it’s easy to operate and inexpensive to maintain. This will ensure that mud additives are homogeneously mixed to prevent dead spots. Agitators will keep the active mud system flowing even when the pumps are disengaged and keep the weighting agents in suspension.

BENEFITS OF AGITATOR MIXER:
     – Increase performance of solids removal equipment.
     – Maintain a uniform mud density.
     – Prevents solids settling , taking up valuable tank displacement.
     – High shear mixing, aids chemical and solids addition.
