Application of Progressing Cavity Pump in Horizontal Well Oil Test
LIU Pan-feng;Institute of Petroleum Engineering,Dagang Oilfield;
Progressing cavity pump is more and more widely used. Because it has few moving parts,high reliability,and could be used to fluid with high viscosity,sand and waxy,and also have increasing incomparable advantage compared with other mechanical oil production. It is used from production wells to oil-test wells. This article analyses the adaptation in test wells based on the working principle of progressing cavity pump. It is used in three wells such as puping3,qiping5 and qiping3. Advantages and disadvantages in suction,system adjustment,well blowing judge,flowing bottomhole pressure and formation production ability are displayed by analyzing the production data of the three wells.
