摘　　要：在对研究区石炭系黄龙组油气资源条件的研究、资源评价方法对比的基础上,选用了成因法(盆地模拟法)和统计法中的油气藏规模序列法、油气藏发现过程法、广义帕莱托法、年发现率法、饱和钻探法等多种方法,对研究区石炭系黄龙组的油气资源潜力进行了定量评价。评价结果表明,除盆地模拟法资源量相对较大以外,其它各方法计算的资源量都较接近,基本上与川东石炭系黄龙组的勘探实际吻合,研究区石炭系黄龙组勘探程度虽高,但仍具有很好的勘探潜力。研究区石炭系存在3大有利勘探方向,即低勘探程度的构造圈闭、构造-地层复合圈闭与岩性圈闭。For the Carboniferous Huanglong Formation in eastern Sichuan Basin, the oil and gas resource conditions were studied, and some methods were applied to assessing resource potential, including genetic method(basin model) and many statistical ways of reservoir scale sequence,discovery process method of oil and gas reservoir, generalized Pareto, annual discovery rate, and saturated drilling. Results show that(1)the calculated resources from other approaches except basin model which obtains a relatively large amount of resources, are roughly fit to actual exploration results;(2)in the study area, the Huanglong Formation still has a better potential despite a high exploration degree at present; and(3)there are three favorable exploration targets, containing structural trap, structural-stratigraphic compound trap, and lithological trap.
