PROLONGED THE OIL WELL LIFETIME BY USING HYDRAULIC JETTING PUMP

Hydraulic jetting pump is a new recovery technique in 90’s, and has gained the ISO9001 attestation in 1994. The pump is mainly for dense oil well, which always easy to happen sand flow and erosion well. The technique has been applied in K71 fault block at Kenxi Oilfield in 1998. which has popularized to 27 wells now. At the same time, well’s lifetime from 110 days has been prolonged to 350 days. The paper introduces the hydraulic jetting pump’s recovery technique. The preferment result used in Kenxi Oilfield was introduced.
