Abstract

Abstract:

Quantitative evaluation technologies of gas source rocks are used to study the gas generating capacity of various source rocks in the major petroliferous basins in offshore China.The following understandings have been achieved: ① gas yields of coal-measure source rocks in Qiongdongnan basin,Pearl River Mouth basin and East China Sea basin are very high.Gas generations in these three basins have the characteristics of dual peaks and wide gas windows;② marine source rocks in Yinggehai basin are mainly composed of terrestrial organic matters,and gas generation in this basin is also characterized by high gas yield and wide gas window;③ as to the lacustrine source rocks in Bohai,East China Sea,Pearl River Mouth and Beibuwan basins,except for some mudstones with typeⅠkerogen have high gas yield,the mudstones with type ₁ kerogen which are widely distributed in these lake basins have relatively high gas yield and only a single peak of gas generation.Their gas windows are much narrower than that of coal-measures and marine source rocks.

Key words: coal-measure source rock, marine source rock, lacustrine source rock, gas generating capacity, pattern of gas-generation, pyrolysis simulation experiment, petroliferous basin, offshore China
