安塞油田加密调整井的增产措施及效果评价

安塞油田1996～1999年共打加密调整井65口,通过对这些加密井的试油、压裂资料分析,认为加密井的单井产量受其加密方式的影响,在水未波及地带或注水形成的异常高压区加密均取得较好的效果.加密井适合特低渗透油田开发,是安塞油田保持稳产的主要开发技术之一.

Stimulation Measure and Results Evolution of Infill Adiustrnent Well in Ansai Oilfield

The sixty five infill adjustment wells had been dug during four years from 1996 to 1999 in Ansai oilfield.By analyzing their testing and fracturing data,it is concluded that single infill well's production rate is affected by its infill way and a good result could be gained where infilled at areas without being involved by water and abnormal pressure caused by water injection.In addition,infill wells are suit for developing in low permeability oilfield,which is one of the major development techniques to keep a stable reservoir yield.
