准噶尔盆地中拐凸起上二叠统佳木河组火山岩油气成藏演化
Evolution of Volcanic Hydrocarbon Reservoirs of the Upper Permain Jiamuhe Formation in Zhongguai Uplift,Junggar Basin
摘要
Abstract
To the formation of volcanic hydrocarbon reservoirs of the Upper Permain Jiamuhe Formation in Zhongguai uplift of Junggar Basin,the key is the spatial temporal matching relation of tectonic characteristics,lithology,hydrocarbon origin,trap,and source-reser-voir-cap assemblage. The evolution of volcanic hydrocarbon reservoirs of the upper Permain Jiamuhe Formation in the studied was com-prehensively analyzed based on drilling data,logging interpretation,palaeogeomorphologic reconstruction,and seismic coherence tech-nique. The results show that volcanism controls the scale,lithologic lithofacies and physical property of the reservoirs in the study area, and the thick volcanic rock accelerated the generation of hydrocarbon in the Jiamuhe Formation. A "fault-convex" structure showing a pattern of banded nappe was developed in the eastern slope of Zhongguai uplift. Affected by long-term weathering and post tectonic movements,the favorable reservoirs with dissolution pores and fractures were formed in the higher position of banded nappe"fault-con-vex" paleogeomorphology of the Jiamuhe Formation,and the favorable reservoir-cap assemblage was formed together with the weathering clay rock above them. Within the banded nappe,the faults intersect,the fault traps were well developed,and a north-south hydrocarbon-enriched belt was formed in the Jiamuhe Formation of Zhongguai lift,Junggar Basin.关键词
