中美致密砂岩气成藏分布异同点比较研究与意义
Comparison study on accumulation & distribution of tight sandstone gas between China and the United States and its significance
摘要
Abstract
The tight gas has already been the important field of the global unconventional resource exploration. The distribution of tight gas in China is very wide; for example, the scale development of Ordos Basin and Sichuan Basin have been achieved . The Rokey Mountain in the United States is the area where the tight gas is well developed. Comparative study on the generation condition and reservoir characters of American tight gas is the useful way to accelerate the development of tight gas and open up the thought of exploration. The result of comparative analysis of light gas reservoir between China and the United States shows; tight gas of China and the United States havs many common characters, for example, most source rock being coal measure strata, tight reservoir, abnormal formation pressure, resource and reservoir intimate contract and gas reservoir gross distribution and so on; otherness is mainly reflected in light gas source depositicnal environment,thermal evolution extent, reservoir heterogeneity, densifying factor, the longitudinal and plane distribution characteristics of gas reservoir. The main factors of are the character of depositional basin, sedimentary environment and deuterogene tectonic feature. In allusion to the particularity of Chinese tight gas, the key points of tight gas exploration and development are intensifying reservoir heterogeneity, high grade reservoir forecast, and the study of gas reservoir distribution and striving to make technological breakthrough to increase weE cumulative production,关键词
