摘　　要： 复杂断块油藏构造及油水分布复杂，开发调整难度大。基于油田早期压力测试及生产过程中的动态监测资料，通过物质平衡法、递减曲线法、相对渗透率曲线等油藏工程方法动态分析了各断块存在的问题，同时基于各断块地质特征将18个断块分为面积大层系多、面积小层系少等6类。应用结果表明，采用细分层系调整、注采系统调整、补充新井、水平井、大斜度井、侧钻及补孔等措施既能有效地控制产量递减及含水上升率，又能增加油田可采储量。 Because of the complicated structures and oil-and-water distribution of complex faulted oil reservoir, the development adjustment is rather difficult. On the basis of the dynamic monitoring data of early pressure test and in the course of production, the existed problems of each block are analyzed dynamically by means of oil reservoir en- gineering methods such as material balance, decline curve and relative permeability curves and so on. At the same time, based on the geological characteristics of each fault block, 18 fault blocks are classified into 6 types of differ- ent sizes of area and different numbers of series and so on. The application results show that the production decline and water rise ratio are effectively controlled by the following measurements such as subdivision series adjustment, injection-production system adjustment, make-up new well, horizontal well, highly-deviated well, sidetrack drilling and additional perforation and so forth. And moreover the reserves of the oilfield can be increased.
