双靶点水平井在福川地区的成功应用

Success Application of Dual-target Horizontal Well in Fuchuan District

为有效解决福川矿区井场用地及资金限制致使老矿区挖潜实施难度大的问题,四川盐业地质钻井大队在该地区成功实施双靶点水平井钻井工艺,配合井口旋转防喷装置克服了施工过程中井下复杂涌漏和裸眼段长等复杂情况,大幅提高矿区产卤量和经济效益,该技术具有极大的应用推广价值。

In order to effectively solve the land and capital limit in the Fuchuan mining area, and difficulty of exploiting the old mining area, Sichuan Salt Industry Geological Drilling Crew successfully implemented the dual-target horizontal well drilling process in the region.The complicated leakage of the hole and the length of the open hole during the construction are overcome by the rotary blowout preventer of the wellhead. This technique greatly improves the quantity of halogen and economic benefit and has great application and promotion value.
