【摘要】：珠江口盆地东部经历了30多年的油气勘探和四轮油气资源评价,历轮评价的方法和结果存在较大的差异,有必要开展油气资源的动态评价。按照国际通行的资源概念,以预测油气地质资源量和剩余地质资源量作为评价工作的主线,综合应用盆地模拟法、油田规模序列法和圈闭法进行了珠江口盆地东部油气资源评价,并从评价单元、构造单元、层系、埋深、油品、水深、储层物性等方面分析了油气资源的分布特征,结果表明:珠江口盆地东部油气资源丰富,石油总地质资源量约64×108t,天然气总地质资源量约27×1011m3;油气总探明率低,总石油探明率为12.86%,总天然气探明率为7.11%,勘探潜力大;油气地质资源分布不均,整体呈现北油南气的分布格局,其中石油地质资源主要分布于新近系和古近系,以浅层、中深层为主,浅水区多于深水区,以中轻质油为主,在中高渗储层中分布居多,而天然气地质资源量主要分布于古近系和新近系,以中深层和浅层为主,深水区占绝对优势,低渗—中高渗储层均有分布。本文综合法获得的珠江口盆地东部油气资源的动态评价结果及分布特征,可为该地区勘探评价和勘探方向优选提供重要参考。
[Abstract]:The eastern Pearl River mouth Basin has experienced more than 30 years of oil and gas exploration and four rounds of oil and gas resource evaluation. It is necessary to carry out dynamic evaluation of oil and gas resources. According to the internationally accepted concept of resources, the prediction of oil and gas geological resources and the amount of remaining geological resources are the main lines of the evaluation work, and the basin simulation method is applied synthetically. Oil field scale sequence method and trap method are used to evaluate the oil and gas resources in the eastern Pearl River mouth basin, and from the evaluation units, structural units, strata, buried depth, oil products, water depth. The distribution characteristics of oil and gas resources are analyzed in terms of reservoir physical properties. The results show that the eastern part of the Pearl River mouth basin is rich in oil and gas resources, with a total petroleum geological resource of about 64 脳 108 tons. The total geological resource of natural gas is about 27 脳 1011m3; The total oil and gas detection rate is low, the total oil detection rate is 12.86, the total natural gas detection rate is 7.11, and the exploration potential is great. The distribution of oil and gas resources is uneven, showing the distribution pattern of north oil and south gas as a whole, in which petroleum geological resources are mainly distributed in Neogene and Paleogene, mainly in shallow, middle and deep layers, and more in shallow water than in deep water. The medium and light oil is the main oil, and the distribution is mostly in the middle and high permeability reservoirs, while the natural gas geological resources are mainly distributed in Paleogene and Neogene, and are mainly in the middle and deep layers, and the deep water area is the absolute predominance. The dynamic evaluation results and distribution characteristics of oil and gas resources in the eastern Pearl River mouth basin obtained by the comprehensive method can provide an important reference for the exploration evaluation and optimal selection of exploration direction in this area.
