高含水油田开发方案调整数值模拟研究
|
摘要
别古庄油田京11断块从1979年投入开发截至到2014年12月采出程度达到50.97%,综合含水达到90.6%,已经进入高含水开发后期。为了搞清油藏剩余油分布并进行化学驱试验,提高采收率和经济效益,对该油藏进行了开发数值模拟研究。通过采用Eclipse黑油模型,结合地质分析和油藏工程评价,在产油量、含水率和地层压力等历史拟合的基础上,针对化学驱设计了3套不同的调整开发方案,并对其开发指标进行了预测。通过预测结果分析,建议采用各项开发指标为最佳的调整方案,为合理开发京11断块油藏提供了依据。
The recovery degree of north China Beijing 11 fault block reaches to 50. 97% from 1979 at which of development until December of2014,comprehensive water cut is 90. 6%,and it has entered into high water-cut development period. In order to find out reservoir remaining oil distribution and carry out chemical flooding experiment,improve the recovery efficiency and economic benefits,the reservoir numerical simulation study has been developed. Through the adoption of Eclipse black oil model and combining with geological analysis and reservoir engineering evaluation,on the basis of history matching of the oil content,moisture content and formation pressure,3 different sets of adjustment plans for chemical flooding are designed,and its development index is forecasted. Through the analysis of prediction results,it is recommended that the best adjustment scheme using every development indicators provides the basis for rational development of oil reservoir at Jing 11 fault block.
