Description
Technical Field
The invention relates to the technical field of petroleum exploitation assistance, in particular to a rack-meshed oscillating drilling fluid recycling device for petroleum exploitation.
Background
Drilling fluids, also known as drilling muds, are a general term for the various circulating fluids used in the drilling process. In the drilling process, the drilling fluid not only can cool and lubricate the drill bit effectively, but also has the balanced bottom pressure, avoids the effect of blowout and well kick, and moreover, the drilling fluid can also transmit power and take core and sample. The drilling fluid is mainly divided into three categories, namely water-based drilling fluid, oil-based drilling fluid and gas-based drilling fluid according to different dispersion media.
In the drilling process, the drilling fluid enters the bottom layer through the drill rod and is discharged together with waste residues generated in the drilling after the drilling effect is completed, the drilling fluid is high in price and can damage the environment, so that the drilling fluid needs to be recovered, and the solid control system is used for recovering the drilling fluid. Solid control systems are also known as drilling fluid circulation systems and drilling fluid purification systems. The solid control system mainly comprises solid control equipment such as a drilling fluid vibrating screen, a vacuum degasser, a desander, a deslimitor, a horizontal spiral centrifuge and the like. The solid control equipment is like a series of sieves with different sizes and functions, and the purification and the reutilization of the drilling fluid are realized through layer-by-layer filtration.
The desander is a secondary solid control system of a drilling fluid recovery process, and the drilling fluid enters the desander after being primarily screened by a drilling fluid vibrating screen to remove solid phase particles with the particle size of 40-80 mu m contained in the drilling fluid. However, when the traditional sand remover separates the drilling fluid from the solid-phase particles, the effect is not good, a large amount of small solid-phase particles still exist in the drilling fluid, and not only can the later-stage oil exploitation be influenced, but also the service life of later-stage exploitation machinery can be influenced.
