Select Suitable Solids Control Equipment to Keep Drilling Mud Property

At the beginning of drilling history, people use clean water to dilute the solids content in drill mud. Sometimes, diluting drilling mud thorough adding water is good way and necessary , but for some high density drilling slurry , the dilution cost is very high. If this dilution costis used to purchase solid control equipment, the economic benefit will be better.

 One or more of the following technologies are used on site to remove the solid phase in the drilling fluid

 screening technology: shale shaker for drilling fluid, and strong water sensitive mud shale removal device;

Cyclone separation technology: desander and desilter;

Centrifugal separation technology: coarse mesh and sedimentation centrifuge;

Gravity sedimentation technology: sedimentation tank and dewatering device.

In general, these technologies can be accomplished by using separate equipment. However, in some cases, these equipment can be used in combination. For example, like the mud cleaner, it is to fix a hydrocyclone on the vibrating screen. Another important combination device is the drill cuttings dryer (also known as rotary shale shaker), which is a centrifuge equipped with a conical shale shaker, which can be used to separate the drilling cuttings in the drilling fluid to recover the drilling mud before treating the drilling cuttings. In addition, these devices help to improve the solid phase removal efficiency. For example, sometimes a vacuum or atmospheric degassing device (installed in front of the centrifuge, especially between the shale shaker and the desander) is installed to remove the gasbubbles in the drilling fluid that can cause the pump to evacuate and reduce the density of drilling fluid.

Select the suitable solids control equipment is economic way to keep the mud property, improve drilling efficiency and protect rig machine. GN Solids Control can provide all these equipment and also customized system. If your have demanded on these, welcome to contact us.

The Damage of Drill Cutting to Oil Well

As we all know there will be large drill cutting when drill well, especially in the petroleum drilling ,as long as the more drilling depth, the drilling mud is the most important thing decide if we can finish the drilling work, bad drilling mud will directly destroy the well and eve rig machine. How to remove out drill cutting is main job for solids control and guarantee the fluid property.

However, some remarks that drilling cuttings are beneficial to drilling fluid are wrong. He did not realize that cobalt cuttings have existing and potential harm to drilling fluid. Generally speaking, the phenomenon that drilling cuttings increase the solid content of drilling fluid will not appear soon. The harm has a certain process, and the economic impact can not be shown to us soon. Therefore, these people do not believe that the harm of drilling cuttings to cobalt well fluid can reach the extent of their actual damage. Drilling cuttings will increase the drilling cost, damage the reservoir and increase the cost of drilling fluid treatment. Therefore, drilling cuttings are related to the following special problems: (1) filtrate damages the reservoir; 2) Limited cobalt velocity (3) complex downhole; (4) Stuck drill; (5) Lost circulation (6) direct cost of drilling fluid; (7) Increased processing costs.

In the actual drilling work ,the drilling cutting may have more damage. Therefor use the good quality solids control equipment to remove out drilling cutting and make the good property drilling fluids is very important. GN Solids Control has manufacture solids control equipment for more than 15 years. We can provide the whole set mud system from mud mixer to the management of drilling cutting. Shale shaker ,mud cleaner, decanter centrifuge, mud agitator, mud jet mixer, and shear pump. We exported these equipment to more than 76 countries and served 2000 customers. If you have requirement to drilling fluid treatment, we will be pleased to share our experience.

Trouble Shooting of GN Solids Vacuum Pump

GN solids vacuum pump is different with the normal market pump. Solids vacuum pump was specially developed to transfer the high solids content material or high viscosity material and also some dry solids, such as oil sludge ,sand, cement ,metal power. It has widely application, and it was known by more and more people. This pump is a new product and most people is not familiar with it ,and have no idea how to trouble shot.

This pump is driven by air, as usually we connect to air pressure. Currently GN has 10B,20B,40B these 3 models. every of them required air supplying are 4 m3 /min, 8m3/min and 17m3/min. And the air pressure should between 0.8Mpa. If the suction power and discharge power is not enough, you may check the air supplying. The suitable Air supply is necessary to support the pump work.

Sometimes, the pump suction air down lowed, we suggest you to check if there is any where have the air leakage, especially in the part of limit Switch. The hose connection may loosen after using for several month. The air leakage will cause the suction and discharge power low. you just need to tighten these air hose and to make sure there is no air leakage.

Solids pump is different with electrical pump, select the suitable length of suction hose and discharged hose. If the suction hose is too long, which may lead the suction power too low. The pump can suck 50 meters when the material is water. However, if the material is more viscosity and higher density, reduce the suction hose length. 6 meters is good choice. The suction height is no more than 8 meters, cause it utilize vacuum power, and suction power was dependent on the atmosphericpressure.

Note to clean the pump after using to transfer material and make sure there is no stuck in valve .If you have any other issue when using it, feel free to contact us .
