摘要
按照国家“九五”重点科技攻关项目的实施要求，根据胜利油田侧钻地层特点，建立了侧钻短半径水平井轨迹测量及控制的新模式和新技术。研究解决了原始井眼套管内的测量精度以及开窗侧钻方式、造斜井段和水平井段的随钻测量和轨迹控制等技术难题。采用了弯壳体马达钻进为主的方式进行水平段井眼轨迹控制。将研究的重点放在提高侧钻短半径水平井的井眼轨迹测量精度和控制能力上。
Hole trajectory measurement and monitoring techniques for sidetracking short radius horizontal wells have been developed in accordance with formation properties in Shengli Oilfield, which include bent casing motor acting as driver to control horizontal section. The paper places emphasis on trajectory measurement and monitoring capability improvement.
