It better solves the problems of production test and draining in the particular reservoirs. The draining of the screw pump can actually reflects the liquid property and productivity of the formation; special cable in the hollow rod can increase the fluid’s temperature, reduce its viscosity, and therefore enhance the mobility; the formation tester can be used for acquiring formation pressure, temperature and so on. Field application indicates that this technology is with better application future.展开更多
