Application of screw pump in oil testing and drainage

In the process of oil testing, in order to collect geological data such as reservoir liquidity, productivity, and formation parameters, it is necessary to use artificial lifting methods to discharge liquids from the wellbore according to the working system for non self spraying production layers or layers with poor self spraying ability. The method to solve this problem is called oil testing and drainage, and the corresponding drainage method is collectively referred to as oil testing and drainage production technology.
