辽河油区储采比与递减率关系研究及探讨

多年的开发实践使油田规划工作者认为储采比与递减率紧密相关。为研究二者的相关程度，从储采比和递减率定义入手，详细研究并推导了具有代表性的6种产量变化规律储采比与递减率的理论关系式，并尝试性地应用于辽河油区不同油品油藏中。同时对储量一定（目前储量）及变储量两种情况下，分油品对该油区储采比与递减率的关系进行细致研究探讨。指出该油区储采比的确是影响递减率的一个重要指标，且与递减率呈反向关系。但是，将理论曲线应用于地质条件十分复杂的辽河油区递减率预测中还存在很大误差。

Research and Discussion about the Relationship Between Reserve/Production Ratio and Decline Rate in Liaohe Oil-bearing Area

After many years experience in oilfield development, planning workers take it for granted that reserve/production ratio is closely related to decline rate. In order to understand the relationship, theoretical relationship equations about reserve/production ratio and decline rate for 6 production change rules have been studied. The above research starts from the concepts of reserve/production ratio, and the relationship equations have been used in different oil reservoirs of Liaohe oil-bearing area. The relationship between reserve/production ratio and decline rate in this oil-bearing area is discussed under two conditions of given reserves and changing reserves. The reserve/production ratio here is one important index influencing decline rate, and it is in inverse ratio with decline rate. However, great error still exists when applying the theoretical curve to decline rate prediction in Liaohe oil-bearing area, of which the geologic conditions are very complicated.
