摘　　要：随着四川盆地东北部台缘礁滩相油气勘探的深入,礁滩复合体储量计算之重要性逐渐显现。综合利用地质、物探、测井手段,提出解决礁滩复合体精细刻画和描述、气藏精细描述与选取储量计算参数三方面难点的方法,分别采用等值线面积权衡法、体积权衡法、孔隙体积权衡法计算出有效厚度、有效孔隙度、含气饱和度,最终计算出合理的涪陵地区A井区长兴组二段礁滩复合体气藏探明地质储量为76.53×108 m3。with the deepening of the oil and gas exploration of the platform margin reef and shoal in the Northeast Sichuan Basin,the reserves calculation of their compounds was becoming more and more important.It is proposed that the methods to solve the issue of beach reef compounds for fine description of their natural gas reservoirs and selection of reserves parameters are proposed with the full utilization of geologic,geophysical and logging data,then by using the methods of contour area tradeoff,volume balance and pore volume balance to calculate effective thicknesses,effective porosities and gas saturations respectively,finally calculation of the proven geological reserves of the beach reef compounds is 76.53×108m3.
