为了减少水平井造斜段滑动钻进比率,提高施工效率,实现降本增效,公司研发人员积极探索,与螺杆厂家合作开展7LZ165mm×7.0MPaDW1.5°高增斜率单弯螺杆钻具试验和改进工作。经过科研理论分析及室内实验提出了7LZ165mm×7.0MPaDW1.5°单弯螺杆钻具的可行性,为了确保螺杆的实用性,在鄂北工区进行了现场跟踪和数据收集,优化后的螺杆钻具与没有改良的螺杆相比平均滑动比例减少了27.65%。
In order to reduce the rate of horizontal well drilling slip ratio, improve construction efficiency and achieve cost reduction and efficiency, the company’s R & D personnel to actively explore, and screw manufacturers to carry out the 7LZ165mm × 7.0MPa DW1.5 ° high slope single-turn screw drilling With testing and improvement work. After the theoretical analysis and laboratory experiments, the feasibility of 7LZ165mm × 7.0MPa DW1.5 ° single-bend screw drilling tool was put forward. In order to ensure the practicability of the screw, field tracking and data collection were carried out in the Hubei North Work Area. After optimization Compared with the screw without the screw, the average sliding ratio decreased by 27.65%.
