我公司与中国石油浙江油田分公司合作,对大安1H21平台八口井进行高频压力压裂、焖井、返排监测与评价。

通过井口安装自主研发的高频压力计和配套的压裂分析软件,监测压裂施工压力及焖井期间压力降落解释服务及返排测试期间动态评估和优化的工作。在该平台开展高频压力动态监测,综合评价射孔孔眼开启效率、SRV、应力场变化情况,优化压裂泵注程序、确定合理开井返排时机,返排制度优化调整措施等。通过高频压力监测预测出气情况及返排制度提供了建议和理论基础。

大安1H21平台包括上中下三层,对井和层之间压裂液窜流进行分析,制定开井顺序原则:同层最好一起开井返排,对井间窜流较严重的层优先开井返排,避免相邻井压差大,这样会因压敏效应,使得裂缝闭合,导致SRV区域渗透率、裂缝长度等大幅减小。

本次在大安1H21平台成功应用的高频压力监测技术,不仅为压裂优化、返排制度制定、产能预测提供了精准数据支撑与科学理论依据,更为井间、层间压裂液窜流分析及合理开井顺序确定提供了关键技术手段,最大限度保护并提升SRV改造效果。为后续同类型平台及井位的高效开发提供了可复制、可推广的成熟技术路径。
