发布时间:2018-11-22 11:13
【摘要】:裂缝性油气藏开采过程中,压力补充是一个复杂的问题。裂缝性油气藏主要的油气运移通道是裂缝,储集层的原始物性非均质性强,孔隙度与渗透率在储层平面分布上及储层纵向上存在很大差别。油井生产与水井注水的通道包括裂缝与空隙,油井生产特征各异,水窜速度与正常采油周期不好掌握,水井注水也存在很大难度。本文以黄沙坨油田为例,通过裂缝特征研究,结合生产现状,调整注采方案,对同类型的油藏开发有一定的借鉴作用。
[Abstract]:Pressure supplement is a complex problem in fractured oil and gas reservoir production. The main migration channel of fractured oil and gas reservoirs is fractures, the original physical heterogeneity of reservoir is strong, and there are great differences between porosity and permeability in the plane distribution of reservoir and the vertical distribution of reservoir. The channels of oil well production and water injection include fractures and voids, the production characteristics of oil wells are different, the speed of water channeling and the normal production cycle are not easy to master, and the injection of water wells is also very difficult. This paper takes Huangshatuo Oilfield as an example, through the study of fracture characteristics, combined with the production situation, adjust the injection and production plan, which can be used for reference for the development of the same type of reservoir.
