定向井就是使井身沿着预先设计的井斜和方位钻达目的层的钻井方法,是由特殊井下工具、测量仪器和工艺技术有效控制井眼轨迹,使钻头沿着特定方向钻达地下预定目标的钻井工艺技术,它是当今世界石油勘探开发领域最先进的钻井技术之一。近几年,吴起地区采用定向井技术使地面和地下条件受到限制的油气资源得到了经济、有效的开发,大幅度的提高了吴起采油厂油气产量并降低了钻井成本,更有利的保护了该区自然环境,经济效益和社会效益显著。
A directional well is a well drilling method that allows the wellbore to reach the target formation along wellbores and azimuths that have been predesigned. The wellbore trajectory is effectively controlled by special downhole tools, instrumentation, and process technology to allow the drillhead to drill underground in a particular direction Target drilling technology, it is one of the most advanced drilling technology in the field of petroleum exploration and development in the world today. In recent years, oil and gas resources that have been restricted by the use of directional well technology in the Wuqi area have been economically and effectively exploited, greatly boosting oil and gas production and lowering drilling costs in the Wuqi oil production plant, District natural environment, economic and social benefits significantly.
