Based on the rock thin section analysis, the sandstone reservoirs of member 2 of Xujiahe
formation, upper Triassic in Xinchang area were studied by using technologies of …

The sandstones in the Triassic Xujiahe Formation in Yuanba area are typical low-porosity
and low-permeability reservoirs. The diagenesis and porosity evolution of sandstones as …

Abstract The Lower Triassic Feixianguan Formation reservoir in the Puguang Gas Field of
the Northeast Sichuan mainly consists of platform margin oolitic beach sediments. The main …

Based on the data of thin section observation, geophysical property test, mercury injection
test and fluid-inclusion temperature test, the characteristics and genetic mechanism of low …

Abstract The Upper Triassic Xujiahe Formation in the Sichuan Basin is a tight sandstone
reservoir with developed dissolution pores, but its formation mechanism is still unclear. In …

The sedimentary micro-facies, diagenetic facies and fracture facies of tight gas sandstone
reservoirs of Upper Triassic Xujiahe Formation Member 2 (Xu-2) in Jinqiu area are studied …

Analyses based on thin section, SEM, mercury intrusion and logging data were combined
with outcrop and core observations to study the characteristics and diagenesis of tight …

The genesis of a reservoir is a result of the combined action of deposition, diagenesis,
tectonic reworking, and interaction of rock and fluid and the evolutionary environment. We …
