摘要
压裂增油一直是江汉油田的主要增油手段之一,但近几年随着勘探开发范围的进一步扩大,遇到的高压、高应力储层不断增多。通过近1年多的压裂施工,对高压井进行统计分析,掌握了江汉油区高压、高应力储层的地质特征,并应用各种手段对储层施工压力和应力特征进行分析,提前预测出高压、高应力地层情况并对后续施工采取相对应的措施,特别是对一些突遇的异常高压井的压裂施工提出解决办法,取得了显著的改造储层效果。
Fracturing Stimulation has been one of main stimulation methods in Jianghan Oilfield. But along with the further enlarging the scope of exploration and development in recent years, high-pressure and high-stress oil reservoirs increasingly appear. The authors, having experienced over-one-year fracturing construction and statistically analyzed high-pressure wells, summarize the geological characteristics of high-pressure and high-stress oil reservoirs, try to recognize the features of reservoir construction pressure and stress, pretest the formation condition with high pressure and high stress in advance, take cotmtermeasures in follow-up construction, and, especially, put forth the solutions to fracturing construction of some unexpected abnormal high-pressure wells, which effectively reform the reservoirs.
