摘要
涪陵地区地处地貌复杂的四川盆地和盆边山地过渡地带,布井受限。丛式井常规钻井模式井场面积及形状变化大,钻机搬迁安装次数多。为减少丛式井平均单井占地面积和提高平台井数,开展井位及井组布置、井口及井组间距优化技术研究。研究结果表明,涪陵地区最小井口间距10 m,最小井组间距40 m。单井组井工厂井位纵向布置和双井组及多井组井工厂井位纵向布置、钻机移动方向大门坡方向相同时,井场面积最小。
Fuling prefecture is located in the transition zone between Sichuan basin and basin side mountains with complex landform,the well site layout is limited.The well site area and shape change greatly under the conventional drilling mode of cluster well,and there are many times of rig relocation and installation.In order to reduce the average single well floor area of cluster wells and improve the number of platform wells,research on optimization technology of well location and well group layout,wellhead and well group spacing was carried out.The results showed that in Fuling prefecture the minimum wellhead spacing is 10 meters,the minimum group spacing is 40 meters.The well site area is the smallest when the longitudinal arrangement of single well group multi-well pad,and the longitudinal arrangement of double well groups multi-well pad and the drilling rig moves in the same direction as the gate slope.
