摘要
水平对接连通井精确定位技术,是一项增加了多项具体应用的综合钻井技术。控制的关键技术要求是：水平段的井身轨迹要控制在首采盐层的底部1-3m,并且与对接井组的直井井底进行点对点的精确连通。近年来岩盐矿藏的开发大多采用了精确定位技术,在水平对接井组施工中引进RMRS精确定位仪器,有效地控制井眼轨迹,已广泛应用在盐类矿产的开采。
The accurate positioning technique of horizontal connected well is a kind of comprehensive well drilling technique which is added several specific applications. The key requirement of controlling technique is controlling the well bore trajectory of horizontal section between 1 -3metres at the bottom of the first exploiting layer of rock salt, and keeping the accurate point-to-point connection with the straight well bottom of the linked well. In recent years, the accurate positioning technique is widely applied on the rock salt mineral resources exploitation, and the RMRS accurate positioning instrument has been introduced to the construction of horizontal linked well. It can effectively control the trajectory of well eye, and it has been already applied to salt mineral resources exploitation.
