摘要
长庆靖边气田下古气藏是以裂缝—溶蚀孔(洞)为主的层状碳酸盐岩气藏。为提高储量计算结果的可靠性,在容积法的基础上,充分考虑沟槽对于储量计算的影响,采用了单井控制面积法、落空井比例法、确定性模型法等多种方法进行计算比较,其中考虑沟槽分布影响后的确定性模型法计算结果最为准确,应用该方法对靖边气田下古气藏储量进行了计算。计算结果为气田深入开发、开发方案设计和扩边井网部署提供了可靠的依据。
The lower Paleozoic gas reservoir in the Jingbian gas field of Changqing is a layered carbonate gas reservoir dominated by fracture-dissolution pores.In order to improve the credibility of reserves estimation,this paper compares many methods based on volumetric method with fully consideration of the impact of grooves,including single well control area method,frustration well ratio method and deterministic model method;of which,the deterministic method with consideration of grooves distribution has presented the most accurate result and is used to calculate the reserves of the lower Paleozoic gas reservoir in the Jingbian gas field.This calculation result provides reliable basis for deep development of the gas field,formulating development program and arranging stepout wells.
