The core analysis method,rock mechanics experiment,three_dimensional finite element numerical simulation and fracture network simulation were used to investigate the fracture system and altitude,fracture property,fracture development degree and distribution in the tight fractured reservoirs with low permeability in the forth member of Shahejie Formation of Hubuzhai Gas Field in Dongpu Depression.The fractures are mainly in the vertical pattern.Four groups of fractures existed in the reservoirs of Hubuzhai Gas Field were distributed in the inclination angles of 33°,83°,109° and 133°,and mainly centralized in 83°.The fractures in original state are mainly the relative isolated structural fracture systems.The connectivity of the different and the same fracture systems was very poor,and the development degree was very different in each part.The fracture network systems are still difficult to be communicated after fracturing.The production behaviors showed that the reservoir had the dual_medium feature,and the productivities of gas wells in the reservoir were different.The lose heart radius had obvious difference between gas wells.The well arrangement was made across the high part of fault block and the fracture development belt in the gas field was drilled,which makes in a good result of oil production.

应用岩心裂缝描述、岩石力学实验、三维有限元数值模拟、裂缝网络模拟等方法 ,对东濮凹陷户部寨气田沙四段低渗透致密裂缝储层的裂缝组系及产状、裂缝性质、裂缝发育程度及其分布规律进行的研究表明 ,户部寨气田储层裂缝主要有 4组 ,其走向方位分别为 3 3°、83°、10 9°和 13 3° ,主要集中在 83°。这些裂缝基本上为垂直缝 ,裂缝原始状态下以相对孤立的构造裂缝系统为主。裂缝组系之间以及同组系裂缝之间连通性差 ,且裂缝的发育程度在不同部位有较大的变化 ,人工压裂后裂缝网络系统在气田开发过程中仍难以沟通。生产动态主要表现为储层具有双重介质特征 ,气井产能差异大 ,气井泄气半径差异大 ,气藏连通性差。沿断块构造高部位采用了线状不均匀布井方式 ,在裂缝发育带钻井 ,取得了较好的开发效果。

According to the geology characteristics of the peripheral Daqing oilfield, some influence factors to the mixed well pattern of 5-spot are studied with numerical simulation method. The influence factors are horizontal well as production well or injection well, horizontal well length, pattern direction in due porosity reservoir and fracture development degree. The results show that (1) Horizontal wells as production wells are better than those as a injection wells. (2) The fraction of well spacing at range of 0.5 to 0.6 is suitable for enhanced oil recovery, fraction of well spacing bigger than o.6 is not good for oilfield production. (3) With the increase of the space between fractures, the time of water break-though of horizontal wells becomes shorter, the period of oilfield production becomes longer and the oilfield oil recovery becomes lower; (4) The horizontal well direction should be vertical to the direction of nature fractures.
