日前 ,化工泰安地质勘察院与国土资源部地科院勘探技术研究所合作 ,在山东省泰安市肥城盐矿施工时 ,将两口定向钻井一次对接成功 ,双井接通点距地表深1 3 1 2 .86ｍ ,偏离靶心垂直误差不超过 0 .5ｍ ,横向误差不超过 1 .5ｍ ,创全国小口径定向钻井最深纪录及密度最高纪录。化工 Recently, in cooperation with the Institute of Exploration Technology of the ASTRI of the Ministry of Land and Resources, the Tai’an Institute of Geology and Chemical Engineering of the Ministry of Land and Resources has successfully connected two directional drilling wells once during the construction of Feicheng Salt Mine in Tai’an City, Shandong Province. The double well connection point is 1 3 1 2 .86m, deviations from the bull’s-eye vertical error of not more than 0.5m, lateral error of not more than 1.5m, creating the deepest record of the country’s small diameter directional drilling and the highest density record.
