南图尔盖盆地Kumkol油田上侏罗统库姆科尔组沉积相研究
Sedimentary facies of Kumkol Formation of Upper Jurassic in Kumkol Oilfield,south Turgay Basin
摘要
Abstract
In order to solve geological problems in Kumkol Formation in Kumkol Oilfield,a lot of core datalogging data and thin section identification data are comprehensively analyzed. The rock types,sedimentary structures,provenance direction,paleontology and sedimentary facies and sedimentary developing characteristics of Kumkol Formation, the Upper Jurassic in Kumkol oilfield,South Turgay basin are studied by combining the comprehensive analysis results with the regional geology background . It is shown that, Kumkol Formation in the studied area is a set of delta deposition formed by river flowing into lake. The provenance is mainly from the south of South Turgay Basin. Delta front subfacies is main sedimentary facies in this area,including a series of microfacies such as subaqueous distributary channel,subaqueous levee,subaqueous crevasse splay,river mouth bar. From J3 to J2 period was the rising process of lake level,and the size of the delta deposition presents weakening tendency. In J1 period,the lake level declined relatively with abundant provenance.The period is the mainly developing period of the delta deposition and the subaqueous distributary channels distribute widely.关键词
