摘要

摘要: 成藏动力学系统研究是石油地质学从静态、定性描述向动态、定量表征研究过程转移的必然产物.根据烃源岩与气藏的空间位置、盖层分布特征、油藏流体性质和压力分布特征以及天然气运聚机理,将松辽盆地北部深层天然气藏划分为远源常压气藏系统和自(近)源超压气藏系统以及无机成藏系统.远源常压气藏系统主要包括以泉一、二段为盖层的K₁d²-K₁q^1-2成藏组合和以登二段为盖层的K₁yc-K₁d²成藏组合;超压气藏系统为自生自储的Jhs¹-K₁yc成藏组合,自(近)源超压气藏系统是松辽盆地北部深层寻找大中型天然气藏的勘探方向.

Abstract: The reservoir-forming system research is the inevitable product of petroleum geology from static,qualitative to dynamic,quantitative description.Deep natural gas system is divided into 3 reservoir-forming dynamic systems such as normal pressure gas reservoir system of remote source,superpressure gas reservoir system of proximal source and inorganic reservoir-forming system,according to spatial location of source rocks,distribution characteristics of capping bed,reservoir pressures and mechanisms of migration-accumulation of natural gas in the northern part of Songliao Basin.There are K₁q^1-2-K₁d² assemblage with gas accumulation closed by K₁q^1-2,K₁d²-K₁yc assemblage closed by K₁d²,K₁yc-Jhs¹ assemblage closed by itself.Superpressure gas reservoir system of proximal source is a favorable direction for large-scale and medium-sized natural gas reservoirs exploration.
