摘要

摘要: 储量计算中单储系数与含油气饱和度成正比,含油气饱和度与油气富集程度密切相关。基于这一认识,提出用藏控单储系数法计算碳酸盐岩油气资源量,并以塔河油田奥陶系一间房组为例。计算中单储系数主要与已探明储量区的油气成藏条件相类比取值,储层厚度参数主要参考钻井、区域岩溶储层分布规律并与已探明储量区储层类比取值。该方法特别适用于碳酸盐岩地区油气资源量的计算,优点在于充分研究油气运移聚集规律,找出油气成藏的主控因素,类比计算区与已知区的成藏主控因素的差异,不仅使得计算参数的取值更具有地质意义,同时也避开了容积法中储层孔隙度、含油饱和度取值地质难题,计算结果更加合理。

Abstract: Unit coefficient refers to hydrocarbon bearing volume in unit reservoir.In reserves calculation,it is in direct ratio to oil saturation which has a close relationship with hydrocarbon accumulation degree.On this basis,a method used in reserves calculation in carbonate formation with unit coefficient is put forward in this paper.For a certain reservoir,unit coefficient can be defined through comparing petroleum geological surroundings to conditions of the other known reservoirs.Reservoir thickness can be defined according to well condition and regional karst distribution.This method is more advantageous in carbonate formations due to the following points: taking full consideration of hydrocarbon transportation and accumulation;finding the key points controlling oil-and-gas reservoir formation;comparing petroleum geological surroundings with conditions of the known area.In parameters definition,more geological factors can be taken into consideration,and difficulties in reserves calculation with volume method can be avoided,therefore the result of reserves calculation with unit coefficient is more reasonable.
