油田进入中后开发期,受地面条件的限制,定向井、斜井成为油田开发的手段,数量逐年增多。目前东胜公司井斜角大、造斜点高,斜井机械采油为油田开发的重点和难点,必须结合现场经验进行斜井的系统设计和配套优化,提高斜井生产效果。 Oilfield into the post-development period, subject to the constraints of the ground conditions, directional wells, inclined wells as a means of oilfield development, the number increased year by year. At present, Dongsheng Company has a large deviation angle and a high incline angle. Off-grid mechanical oil recovery is the key and difficult point in the development of oilfields. It is necessary to combine the on-site experience with the system design and the optimization of inclined shafts to improve the production effect of inclined shafts.
