摘要:
页岩油井压后放喷投产后期，因诸多因素导致桥塞未完全溶解而影响产能，必须采取钻磨桥塞措施来提高油井产量。针对页岩油水平井连续油管钻磨复合桥塞时，易出现钻屑堆积和卡钻风险等问题，对连续油管钻塞管柱进了优化设计，提出了地面流程、钻磨工作液性能、钻磨工具、施工排量、钻压优选等方面的技术参数和要求，为水平井桥塞钻磨提供技术方案，在H2CHF井、HY3HF井成功实施，并取得良好效果。
Abstract:
In the late production stage of the post-pressure release of shale oil wells，the production capacity is affected by the bridge plugs not completely dissolved due to many factors，and drilling and grinding bridge plugs must be taken to improve well production. Generally，in the drilling and grinding of composite bridge plugs in horizontal wells with coiled tubing，drilling cuttings accumulation and sticking risk would appear. To overcome these problems，the coiled tubing drilling string has been optimized，then it is put forward the technical parameters and requirements for the ground process，drilling and grinding working fluid performance，drilling and grinding tools，construction displacement，and preferred drilling pressure. This provided a technical solution for horizontal well bridge plug drilling and grinding，which was successfully implemented in H2CHF and HY3HF wells，and achieved good results.
