Abstract

Dark shale and silty mudstone are rich in Yanghugou Formation. The thrust nappe moments, popularly developed in study areas, may lead to form thick-layer shale. Geological conditions are good for shale gas accumulation as follows: firstly, the main type of organic kerogen is III, and type II—I, hydrocarbon generation are very strong, also exist, secondly, the thick dark shale, thirdly, the high TOC value and the high degree of thermal evolution of organic matter, at last, the favorable preservation conditions. After studying these conditions, this paper comes to the conclusion that such areas are the most beneficial for shale gas accumulation in Yanghugou Formation: southern Hulusitai, Wuda and Shitanjing.
