摘要
一趟管柱压裂两层是在不动管柱的前提下,利用一趟管柱进行两层压裂,并实现压后试油排液求产,同时通过管柱结构和井下工具的合理设计,实现井下压力监测与压后井温测试,完成压裂、排液、求产、测压、测井温等一整套试油工艺技术.现场应用31口井,成功率为100%.结果表明,该工艺技术可减少压裂液对储层的浸泡时间,降低储层的损害程度;节约下管柱作业费用,改善作业环境,实现绿色施工,具有广泛的推广应用前景.
A technology of fracturing two-layers with single string running means that it can fracture two layers, and finish flowing back and the production testing after fracturing without pulling string. With the reasonable design of string structure and downhole tools, the pressure monitoring and well temperature measuring can be finished, and a complete set of technology is formed that contains two-layer fracturing, flowing back, production testing pressure monitoring after fracturing. The technology was applied to 31 wells, the success rate was 100%. This technology not only reduces the soak time of fracturing fluid to oil pay, the damage scale of oil pay, and the cost of operation, but also improves the operation environment and realizes non-pollution operations.
