Abstract

A breakthrough has been made in the Permian Maokou Formation by the well of YB 7 in Yuanba area of the Sichuan Basin, which shows a great exploration potential. With continuous enrichment of data, it is necessary to strengthen the understanding of oil and gas laws and to summarize the main controlling factors of hydrocarbon accumulation, by which a basis for oil and gas exploration and deployment may be provided. In this paper, basic accumulation conditions and characteristics of gas pools in the Maokou Formation were studied, gas-source correlation and hydrocarbon charging time analyses were carried out, and some main controlling factors for hydrocarbon accumulation were summarized. The study area has favorable conditions for source rock and hydrocarbon preservation. The reservoir is mainly shoal superimposed karst fractured type. The gas pool is characterized by abnormally high pressure and high temperature. The natural gas is accumulated from both kerogen and crude oil cracking gas, mainly derived from the Wujiaping Formation. The oil and gas are largely filled in the Middle Jurassic, characterized by continuous filling. The hydrocarbon accumulation in the study area is mainly controlled by reservoir development, source rock conditions and hydrocarbon preservation conditions.
