The solid control system has favorable performance, stable working as well as long service life. And modern solid control system has realized standardization, series and dedication of the types of the equipment. The most common component of solid control equipment in foreign countries is king cobra screen that has large abrasion performance and tough material. Therefore, it has been widely used in oil drilling industry.
The solid control system for oil drilling safety reflects on its composition. The performance and quality of the drilling fluid solid control equipment are the key factors that influence the solid control technology. And the solid control system is mainly composed of drilling fluid circulation tank, drilling fluid purification process equipment as well as equipment control machines. Among all of them, the drilling fluid purification process equipment includes shaker, degriter, desilter, degasser, centrifuge, sand pump, stirring machine as well as combination machine. And in order protect the environmental sensitivity area, it is also possible to equip the solid control system with drillings recycle and waste liquid process equipment.
The solid control system for oil drilling safety also reflects on the current condition of the solid control equipment. The foreign solid control system is composed of 4 shakers and 2 dryers. This kind of device is able to eliminate the dry particles. The application of the dryer is able to reduce the liquid loss of the sand pump. The screens of these 4 shakers use three-dimensional thin wave screen rather than traditional plat linear screen. And the three-dimensional structure permits that gravity forces the solids to enter into the drape groove, so as to add to the quantity of the liquid passing by. And two layers design is able to add to the screen area and screen holes with liquid processing capacity increasing 70% without any blockage and favorable processing effects.
In recent year, the theoretical study and manufacturing technique have been largely developed of the foreign drilling fluid solid control equipment, which is another solid control system for oil drilling safety. However, there is gap between foreign solid control equipment and local solid control equipment such as the working principle of the shaker and cyclone, performance, service life as well as materials. In addition, there are less classifications of the solid control equipment in our country, which is another reason of choosing solid control system for oil drilling safety.
All in all, the solid control system plays an important role in oil drilling safety to protect the proper operation and maintenance of the solid control equipment. Therefore, the solid control system is a crucial component in oil drilling industry to protect the safety of the oil drilling equipment.
