白庙平1水平井多级分段重复压裂实践（） 摘要: 关键词: 中图分类号:

白庙平1井是套管完井的阶梯式水平井，投产时对主力气层81号层分2段进行了水力喷射压裂改造未获成功，后将主力气层全部射开，产量仍不理想。经分析该井增产潜力巨大，决定使用贝克休斯裸眼井完井分段压裂工具对81号层和其他新射气层进行7级分段压裂改造。设计压裂总液量1520.2 m3，加砂128.1 m3；测试压裂后对施工参数进行了调整，实际压裂总用液1659.6 m3，全井加砂170 m3。压后7 d，?3 mm油嘴放喷排液，日产气8459~18700 m3，日产油12.9~16.8 t，压裂效果显著。该井多段压裂的成功实践指明了中原油田低渗透水平井今后完井和压裂改造技术的发展方向。

Horizontal well multistage refracturing practice in Well Baimiao-H1

Well Baimiao-H1 is a stepped horizontal well with casing completion.The well was stimulated in its main gas layer L81 using hydraulic jet fracturing technique by way of two stages after being put into operation,but did not succeed.Later,all the main gas layers were perforated,and the gas production rate was still not as good as expected.Considering its huge production potential,Baker Hughs open hole completion multistage fracturing tools were adopted,by which multistage fracturing operations with a total of...
