  我公司对“浙江油田”-“大安101H井”进行高频压力监测与评价。通过在井口安装自主研发的高频压力计和配套的焖井及返排优化软件,进行油田现场的压裂实时监测。基于每一段压裂实时评价结果,模拟全井改造情况,进而计算焖井阶段地层压力分布和压降趋势预测。

  根据数值模拟分析,计算与预测不同焖井时间后地层压力分布及压力边界线移动速度,实现最佳焖井优化。

  该井2023年4月2日压裂结束开始焖井,4月13日用2mm油嘴开井返排。开井3日后进行点火,焰高0.3m,分析建议更换为3mm油嘴。

  5月5日-5月10日,连油钻桥塞通井。 

  5月15日更换为4mm油嘴。 

  ;5月22日更换为4.5mm油嘴。

  5月28日更换为5.0mm油嘴。  

  目前已经进入CNG输气阶段,产气初期折日产气2952方,现日产气接近18000方,保持5mm油嘴继续返排。 

  高频压力监测作为一项新技术,公司不断加强这项技术的使用场景和技术深度。该技术是通过对压裂停泵以及焖井、返排期间的压力波动数据进行高频采集,利用波动压力、渗流压力、停泵压力等试井模型,从而评价压裂效果、计算焖井时间、产能评价的一项压裂综合监测评价技术。
