Abstract
The detritus of drilling well carry the important information of stratum, which is the important basis for discovering and evaluating oil and gas layer. So it is important to get detritus from the viscous drilling mud. In this paper, it studies the technology of cleaning detritus. According to the requirements of cleaning process and water - saving on the drilling well spot, DF - Windspout separator cleaner is designed, which is used to clean detritus. The mixture of viscous drilling mud and the detritus are accelerated through the double fluid (DF) system. Then they go into the windspout separation, they are separated to fluid and solid at here. Next the fluid is purified by ultrasonic microfiltration plant. The water can be recycled again. It can ensure the clean debris, the accuracy of collecting debris, accurate, remove the fake block and solves the lack of the dis - continuity of sampling.
