洪湖油田属于复杂断块油藏,具有构造破碎、含油面积小等特点。自2007年二次开发,油田水驱控制、动用程度明显提高。但由于层间矛盾突出,导致层间干扰严重、储量动用不均。基于对洪湖油田开发状况认识,改变目前油田开发策略,以早期的逐层上返的开发方式转变为细分层系开发方式,以油砂体为单位,分区治理,形成单独层系的有效注采井网。 Honghu Oilfield is a complex fault block reservoir with tectonic crushing and oil-bearing area. Since the secondary development in 2007, the waterflooding control and utilization of oilfields have obviously increased. However, due to the contradiction between the layers, leading to serious inter-layer interference, unequal use of reserves. Based on the understanding of the development status of Honghu Oilfield and changing the current oilfield development strategy, the development mode of early recovery from layer to layer was changed to the development mode of subdivision stratification system, and the oil sand body as a unit, Well network.
