本文以辽河油田欢127块为例,针对该区块存在薄、稠、物性差、出砂、直井开采难度大等问题,研究利用侧钻水平井挖潜井间剩余油技术。通过油藏精细描述及剩余油分布规律研究,部署1口侧钻水平井。实施后,取得了较好的生产效果。现场实践表明:利用侧钻水平井能有效地挖潜老区稠油油藏的井间剩余油,为该类油藏的增储上产提供了一条新途径。
In this paper, Huan-127 block in Liaohe Oilfield is taken as an example. In order to solve the problems of thin, thick, poor physical properties, sand production and vertical well exploitation, the remaining oil technology of tapping the horizontal well is studied. Through the study of fine reservoir description and remaining oil distribution, 1 horizontal drilling horizontal well was deployed. After the implementation, we achieved better production results. The field practice shows that the use of sidetracking horizontal wells can effectively tap the residual oil between wells in the heavy oil reservoirs in the old area, providing a new way for the increase of production and production of such reservoirs.
