摘要:
国外致密油开发经验表明,适宜的工程技术与“工厂化”作业模式的有机结合是实现其经济高效开发的重要手段。针对准噶尔盆地吉木萨尔凹陷致密油特点,开展大井丛“工厂化”水平井钻井试验:一个钻井平台部署12口水平井,水平段延伸方向与最小主应力方向平行,相邻水平段间距300 m,水平段长1 300 m和1 800 m;采用批量化钻井作业模式,每部钻机实施3口井;采用五段制三维水平井轨迹设计方法,应用螺杆定向工具与旋转导向工具配合的轨迹控制方式,实现轨迹精细控制;优化井口间距,通过液压推动滑轨实现钻机井间快速搬迁;建立集中处理站,实现钻井液统一处理和集中维护,提高钻井液重复利用率。试验表明,“工厂化”钻井平均机械钻速达到9.19 m/h,较常规钻井提高5.87%;平均钻井工期64.88 d,较常规钻井缩短19.65%;钻井液重复利用率达到28%. 降低成本增加效益成果显著。
Abstract:
The practical experiences of tight oil development abroad indicate that the combination of proper engineering technologies with factory?like operation pattern is an important tool for economic and efficient production of tight oils. Based on the characteristics of tight oil in Jimusar sag of Junggar basin, this paper recommended a factory?like drilling test of cluster horizontal wells as follows: 1)12wells in a drilling pad were arranged, the horizontal section extensions paralleled to the minimum principal stress orientation, and the distance between adjacent sections was 300m, with the horizontal?section lengths of1300m and1800m; batching drilling operation pattern was adopted, with3?well drilling for each of rig;2)five?section profile was used for three dimensional horizontal well in track design, realizing the fine track control by combination of screw rod directional tool with rotary steering drilling tool; 3)the optimization of wellhead spacing is run by hydraulic drive slide rail for quick rig moving; 4)constructing central treatment station to maintain or treat drilling fluid for increaseof repeating utilization factor of drilling fluid. Case study shows that the average rate of penetration of factory?like drilling can reach 9.19m/h, increased by5.87%compared with conventional drilling; the average drilling cycle is64.88days, shortened by19.65%; the repeating utilization factor of drilling fluid reaches28%. Hence using this drilling technology can effectively reduce the cost, improve efficiency and/or benefit
