小洼油田经过十多年的开发生产,由于地质、工程等原因,很多油井、注汽井闲置或报废,造成局部地区井网不完善,油层动用程度较低。近几年来,随着侧钻工艺及其配套技术不断地发展并成熟化,利用侧钻井技术恢复停产井、完善层系井网已取得了较好的效果,同时也为小洼油田剩余油挖潜开创了一条新路。目前侧钻井技术已成为老油田剩余油挖潜的重要手段,具有极大的发展前景和推广价值。 Due to the geological and engineering reasons, many oil wells and steam injection wells are idle or scrapped, causing the well pattern in some areas to be imperfect and the utilization of oil layers to a lesser extent. In recent years, with the continuous development and maturation of the sidetracking technology and its supporting technologies, it has achieved good results by using the side drilling technology to resume the shutdown production well and improve the well pattern. Meanwhile, it also tales the residual oil in the Xiaowa oilfield Create a new road. At present, the lateral drilling technology has become an important means of tapping the potential of remaining oil in old oilfields, and has great development prospect and promotion value.
