川东北地区中浅层天然气勘探潜力
摘要
Abstract
The exploration of marine-facies and terrestrial facies formations in Sichuan basin has made great breakthrough after years of thorough study, discovering some billion square large gas fields, facilitating the implement of project of " East Gas Transmission" , and supporting the national energy strategy. Previous researchers believed that, due to the lack of high-quality hydrocarbon source rocks, the nature gas exploration is stagnant in middle-shallow formations of the northeastern Sichuan basin. The systemic studies are carried out on the hydrocarbon source condition, the reservoir condition, trap condition, the hydrocarbon migration and accumulation condition and the preservation condition in middle-shallow formations of the northeastern Sichuan basin in this paper. And, it is found that there are lots of high quality hydrocarbon source rocks, multiple sets of different types of reservoirs , and several kinds of traps in the middle-shallow formations of northeastern Sichuan basin, and is beneficial to hydrocarbon accumulate by superior migration, aggregation and preservation conditions. From the conditions of hydrocarbon accumulation, we can conclude that there is favorable exploration potential to form big-medium gas fields in middle-shallow formation of northeastern Sichuan basin.关键词
