Principle and Application of Negative Pressure Shale Shaker in Recovery of Oil-Based Drilling Fluid
Since the vibrating screen was introduced into oil drilling from mines,its performance has been greatly improved after decades of development,but its ability to remove drilling cuttings has reached the limit.In the last 40 years,vacuum filtration technology has been applied to drill-ing cementing,with insignificant effects.More than ten years ago,when the vacuum filtration technology combined with high-frequency and low amplitude vibration was applied to drilling solid control,the ability to remove drilling fluid from cuttings was significantly improved,and the vol-ume of drilling cuttings discharged was greatly reduced.In recent years,many negative-pressure shale shakers have been applied in domestic drilling.The principle,main technical parameters,field application and comparative analysis with similar technologies at home and abroad of a nega-tive pressure vibrating screen based on conventional vibrating screen compound negative pressure filtration were introduced.Field application shows that the negative pressure shale shaker has ob-vious advantages in handling capacity,liquid content of drilling cuttings,reduction of drilling cuttings discharge,service life of screen,energy efficiency,equipment costs,economic benefits,etc.The application of the negative pressure shale shaker will play an important role in energy saving and emission reduction and realizing"carbon neutralization".It will gradually replace the conventional shale shaker,which will be an inevitable trend in the development of drilling solid control technology.
