青海祁连地区三叠纪泥页岩地球化学特征及储集条件
An analysis of reservoir conditions and geochemical characteristics of the Trias- sic shale gas in Qilian region, Qinghai Province
摘要
Abstract
Triassic strata with dark shale and carbonate rocks are widely distributed in Qilian region of Qinghai Province. In this pa⁃per, the route geology was surveyed, drilling was conducted, samples from North Qilian and Muli areas were analyzed, and data col⁃lected from south Qilian basin and north Qilian basin were collected. The results show that the thickness of Triassic is large. Most of the organic matters belong to low-medium abundance, with a small part belonging to relatively high-high abundance. The types of organic matters are mainly type II1 and II2, with a small part being type III. The maturity of organic matters have reached low ma⁃ture-mature stage, within the maturity range favorable for the shale gas generation. The values of quartz, plagioclase mineral calcite and other brittle minerals of dark shale are relatively high. The space types of shale reservoirs mainly include two types of pores and cracks. In brief, Qilian Triassic shale shows good conditions for hydrocarbon source and has good exploration prospect.关键词
