摘要: 针对张店油田南38断块开发中仍存在着诸多问题,如:水驱控制程度低、层间动用差异大、局部地区注采井网不完善、压力保持水平低等,在深入开展井网适应性研究、井网调整潜力研究、井网调整技术经济界限研究的基础上,制定了注采井网综合调整对策,进行了井网综合调整部署。Abstract: In view of the problems occurred in South 38 fault block in Zhangdian oilfield,such as low controllable degree of wa-ter flooding,big difference in interlayer production,imperfeet injection-production pattern in some areas and low level of pressure maintenance,a comprehensive adjustment tech nique on injection-production pattern has been carried out,on the basis of research covering well pattern adaptability,well pattern potential and economic boundaries.
