摘要
我国页岩气勘探开发至今,虽在重庆市涪陵区焦石区块已取得显著成绩,形成"焦石开发模式";但对于其他地区页岩气试气压裂技术在仍在摸索阶段,压裂试气工艺将直接影响页岩气井的产量。×××区块页岩气压裂试气技术正在施工中不断改进、完善,并逐渐取得突破。对该地区页岩气水平井成功试验了试气流程优化技术、电动泵压裂技术、微地震裂缝检测技术、"大通径桥塞+可溶性压裂球"工艺技术、连续油管水平井钻磨修套技术、连续油管液压坐封、延时射孔技术、"×××区块模式"新排液技术等压裂试气综合技术,创区×××块8项技术指标,经济效益显著。
My shale gas exploration and development so far, although in Fuling District of Chongqing Jiao stone block has been remarkable achievements, the formation of ＂dry stone development model＂ ： but for other parts of the shale gas fracturing test is still in the exploratory stage technology, test gas fracturing process will directly affect the production of shale gas wells.In ××× block shale gas fracturing gas testing technology under construction continue to improve, improve, and gradually breakthrough.The region horizontal shale gas well successfully tested gas test process optimization technology, the electric pump fracturing technology, microseismic fracture detection technology, ＂Chase Drive bridge plug＋soluble frac ball＂ technology, coiled tubing horizontal well drilling and grinding repair sets technology, coiled tubing hydraulic packer, delay perforating technology, ＂××× block mode＂ new technologies fracturing fluid discharge gas testing integrated technology, a area ××× block 8 technical indicators significant economic effect.
