TAP阀直井分层压裂完井技术综合集成应用完井、分层压裂工艺及水力喷砂技术,提出将多个针对不同产层的TAP阀与套管一起入井注水泥固井,然后通过套管直接进行分层压裂,进行多层改造的一种完井分层改造工艺。其最大优势在于减少多层射孔,简化分层多级压裂施工及配套工序。本文通过在该完井工艺在吐哈油田探井吉深1井中的具体应用,通过管串设计、固井工艺质量要求、分级压裂原理及完井特点等方面进行论述,达到对多气层井开发借鉴新思路、提供新方法。
TAP valve vertical well stratified fracturing and completion technology integrated and integrated application of well completion, fracturing technology and hydraulic sandblasting technology, put forward a number of different production TAP valve casing and casing together with cement injection cementing, and then through Casing directly stratified fracturing, multi-layer transformation of a completion of the stratification transformation process. Its biggest advantage is to reduce the multi-layer perforating, simplifying multi-stage fracturing construction and supporting processes. Through the application of the completion technology in the well Jiyshen 1 of the exploration well in Tuha Oilfield, the paper discusses the design of the pipe string, the quality requirements of the cementing process, the principle of fracturing and the completion characteristics, Develop new ways to learn from new ideas.
