Abstract

Abstract:

Pyrite is a mineral with the deposition of abundant organic matter, and it is not only an important index to restore sedimentary environment, but also can indicate the characteristics of oil and gas in shale reservoirs. This paper used argon-ion polishing-scanning electron microscopy (Ar-SEM) techniques and ImageJ software to study grain size and hydrocarbon significance of shale reservoir of Doushantuo Formation in the Middle Yangtze area. The results show that：①the framboids pyrite in shale of Doushantuo Formation is of small particle size, showing a long anoxic sedimentary environment, which is better for the deposition and preservation of organic matter and provides good conditions for the formation of shale gas; ②the content of pyrite has positive correlation with the content of adsorbed gas in the shale of Doushantuo Formation, thus we can predicate adsorbed gas in shale according to the content of pyrite; ③iron is the necessary material for deposition of organic matter, high iron content is beneficial to the enrichment of organic matter, and the organic matter content influences the shale gas generation and storage capacity, so we can predicate maximum shale gas-bearing area according to the enrichment degree of pyrite.

Key words: tight oil, permeability, big pore interval porosity, southern placanticline, Songliao Basin
