摘要
应用油气成藏流体动力系统分析的思路,通过研究三塘湖盆地马朗凹陷地层格架内流体动力学、化学特征、地温分布特征以及它们之间的相互关系规律,同时对凹陷区域流体动力系统沉积和构造演化过程进行了分析,马朗凹陷在纵向上可划分为侏罗系侧向弱开放性和二叠系垂向开放-弱开放性二个油气成藏流体动力系统,并按各个系统的类型分析了它们的成藏条件,为马朗凹陷的进一步勘探提出了重点关注的区域。
Hydrodynamics, chemical feature and underground temperature distribution characteristics and their relations in Malang sag Santanghu basin are studied by the theory of liquid dynamic system in oil-gas accumulation. Meanwhile, the course of deposition and structural evolution in the hydrodynamic system of the sag region is analyzed. The results show that two liquid dynamic systems are vertically classified in Malang sag, ie, Jurassic feeble lateral open and Permian vertical-weak open or feeble open. Conditions for forming oil-gas accumulation are discussed according to the type of these systems. Finally target zones to be focused in future exploration are put forward.
