Abstract

Abstract: For a basin with low degree exploration, looking for the high-quality hydrocarbon source rocks is significant for the choice of exploration direction. Based on a large amount of test and analysis data, we took Hari sag in Yingen-Ejinaqi basin as the research object, and studied the petrological and geochemical characteristics of the high-quality source rocks in Yingen Formation, the source of organic matter, and their forming conditions. The results reveal that the source rocks are micritic dolomites and dolomitic mudstones. The average value of w(TOC) of the source rock is 5.62%, extremely high abundance of organic matters. The organic matter is type I-type Ⅱ₁, belonging to sapropel, or partial sapropel. Although the overall maturity is relatively low, the bottom of the source rocks has reached the mature thermal evolution stage with high potential of hydrocarbon generation. The source of organic matter is the mixed of higher plants and aquatic organisms. The Pr/Ph value of high quality source rocks is 0.19-0.27, which represents a strong reducing sedimentary environment; the gammacerane index is 0.30-0.54, and such high content of gammacerane shows its high salinity of sedimentary environment. High productivity generated by algae blooming and anoxic environment are the two key conditions to form high-quality hydrocarbon source rocks.

Key words: Yingen-Ejinaqi basin, Hari sag, Yingen Formation, high-quality hydrocarbon source rocks, geochemical characteristics, formation environment
