为估算油气探明储量,介绍了探井进尺和探明储量间的2种统计模型:龚帕兹模型和指数模型.根据实际资料,应用2种模型,估算了沧东-南皮凹陷和任丘古潜山区带的最终可探明储量,并讨论了模型和地质单元类型的关系.结果表明:两地区累计探明储量与预测探明储量的相关因数均大于0.75;龚帕兹模型较适用于油气藏类型较多、地质状况较复杂的地质单元,指数模型适用于地质状况比较简单的单元.
In order to estimate the proven reserves of oil and gas, two kinds of statistical models of the footage and the proven reserves of the exploration well are introduced: the Gompaz model and the exponential model.According to the actual data, two models are used to estimate the Cangdong-Nanpi depression and the Renqiu The results show that the correlation coefficients between the cumulative proved reserves and the predicted proved reserves in both areas are all greater than 0.75. The Gypspaz model is more suitable for Geological units with more types of reservoirs and more complex geological conditions are suitable for units with relatively simple geological conditions.
