  我公司与中国石油及吐哈油田公司合作,对“吐哈油田”-“柯新1井”第1段至第15段压裂、焖井、返排进行高频压力监测与评价。 

  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,分析瞬态压力响应特征及流态规律,不仅可以获得地层渗透率、表皮因子、裂缝半长、可开采储量等参数,还可以得到地下优势流动通道,为降耗、挖潜等提供有效服务,达到反演单井、井组地下参数目的。

  实时给出了裂缝的开启情况及位置,为后续该井返排过程中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。

  “柯新 1H 井”完钻井深 4531m,垂深 3321.58m,水平段长 937m,钻遇煤层 479m/5 段,煤层钻遇率 51.1%,3655m、4260m 为地质识别断层,本井全井段采用高频压力听诊技术进行施工监测,优选 8 段进行示踪剂监测(3、5、6、7、9、11、12、14),压后做分布式光纤产液剖面监测4223m、4315m 为井漏识别断层。

  高频压力监测是一项新技术,我公司一直致力于研究和开发新的油田技术,公司不断加强这项技术的使用场景和技术深度,为提高我国天然气勘探开发水平和保障能源安全做出贡献。为该技术在后续井中的进一步推广应用奠定基础。
