卫42块整体压裂改造方案研究

RESEARCH ON RECONSTRUCTION PLAN OF INTEGRAL FRACTURING IN WEI 42 AREA

卫4 2块自1985年上报探明储量以来,一直因构造、储层分布复杂,产能较低而做为难动用储量区块,经过十几年的勘探实践,尤其通过1997年的滚动勘探,该块的构造特征和油水关系已较清楚,目前已实施开发方案。由该块过去试油成果认识到,若要提高该区油井产能,必须实施压裂改造,同时为配合该区块有条不紊地合理开发,必须对该区进行综合研究,制定出合理有效的整体压裂改造实施方案。

The Wei 40 zone is the reserves, which is difficult for producing, because of the complicated structure and reservoir distribution and lower capacity, especially through the rolling exploration in 1997. Now the production plan in the zone has been carried out. According to the production achievements for the past years, we recognized that if the well capacity in this zone should be enhanced, the fracturing reconstruction should be developed .To provide the reference for the yield increase and dependable crop in the zone, the reasonable and effective reconstruction plan of integral fracturing should be established.
