摘要

为评价大民屯凹陷剩余资源潜力,指出有利勘探区带,研究了大民屯凹陷的源控油气作用,即大民屯凹陷有效烃源岩对油气的来源特征、主要成藏期次、油气分布范围和资源潜力的控制作用。结合油气成藏体系和地质门限控烃理论,评价了大民屯凹陷各个油气成藏体系的排烃量、资源量和剩余资源量。大民屯凹陷划分为上、下两套成藏组合,10个油气成藏体系,总的排烃量为14.66×108t,资源量为6.34×108t,剩余资源量为3.098×108t,勘探前景较大;其中,最有利的勘探区带有3个,分别为成藏体系为Ⅰ、Ⅲ和Ⅱ,剩余油气资源量分别为1.163×108,0.567×108和0.409×108t。

Abstract

In order to evaluate the residual oil and gas resources and identify the favorable exploration areas, the hydrocarbon-controlling function of hydrocarbon source rocks in Damintun Depression is studied in this paper. The origin, the accumulation period, the distribution extent and resource potential of oil and gas in Damintun Depression are found to be controlled by the effective hydrocarbon source rocks. The volumes of hydrocarbon expulsion, the resources and the residual resources are calculated based on the theories of the hydrocarbon accumulation system and the hydrocarbon-controlling function of the geological threshold. The Damintun Depression is divided into two reservoir-forming combinations of the upper and the lower parts, with a total of ten hydrocarbon accumulation systems. The total volumes of hydrocarbon expulsion are 14.66×108t, the volumes of the resources are 6.34×108t and the volumes of the residual resources are 3.098×108t. There are three most favorable exploration areas, including the hydrocarbon accumulation system Ilower, the hydrocarbon accumulation system IIIupper and the hydrocarbon accumulation system IIupper. Their volumes of residual resources are, respectively, 1.163×108, 0.567×108 and 0.409×108t.
