摘　　要：本文针对缝洞型碳酸盐岩油气藏提出了改进容积法这种新的储量估算方法,并将这种方法与几种常见的储量估算方法进行了比较分析,最后通过对研究区油气藏进行精细建模计算出的储量作为标准对各种结果进行检验。结果发现静态容积法和溶洞孔隙体积比法计算出的储量误差相对较大,改进容积法相对其他方法具有操作简便的特点,同时也具有更高的准确性,对于油气田勘探开发初期进行储量估算评价具有重要的现实意义。This paper presents a new method of reserve estimation for fractured-cave carbonate reservoirs,which is improved volumetric method,and compares this method with several common methods of reserve estimation.Finally,the reserve calculated by fine modeling of reservoir in the study area is used as a standard to test various results.The results show that the errors calculated by static volume method and cave pore volume ratio method are relatively large.The improved volumetric method has the characteristics of simple operation and higher accuracy compared with the other methods.It has important practical significance for reservoir estimation and evaluation in the early stage of exploration and development of oil and gas fields.
