在计算碳酸盐岩油藏和孔隙性砂岩油藏的石油地质储量时,用众所周知的容积法和物质平衡法计算,往往碰到油层有效厚度、有效孔隙度、含油面积、地层水侵量等参数难于确定的问题。由于地质储量数值不够准确,给油田开发、动态分析带来许多困难。本文主要介绍地层压力高于饱和压力时处于弹性水驱条件下无气顶油藏的储量计算。根据地层弹性能量的消耗来近似计算石汕地质储量的方法,称为弹性物质平衡法。
Calculating carbonate reserves and porous sandstone reservoirs with known petroleum volumetric and mass balance methods, they often encounter effective reservoir thickness, effective porosity, oil area, formation water intrusion, etc. Difficult to determine the parameters of the problem. Due to the inaccurate numerical value of the geological reserve, it has brought many difficulties to the development and dynamic analysis of the oilfield. This paper mainly introduces the calculation of reserves of gas-free reservoirs under the condition of elastic water flooding when the formation pressure is higher than the saturated pressure. According to the strata elastic energy consumption to approximate the calculation method of geological storage in Shishan, known as elastic material balance method.
