The injectivity of saline aquifers is one of the most important factors affecting CO 2
geological storage. However, CO 2 injection fields showed that a lot of crystallized salt …

In the development process for a fractured-porous gas reservoir with developed fracture and
active water, edge water or bottom water easily bursts rapidly along the fracture to the …

Deep fractured vuggy reservoirs are characterized by complex structures, harsh formation
conditions and strong heterogeneity. Accordingly, foam stability was first assessed under …

CO 2 flooding to enhance gas recovery (CO 2-EGR) with CO 2 storage offers the prospects
of significant environmental and economic benefits by increasing CH 4 recovery while …

Organic rectorite (OREC) can significantly improve the resistance of asphalt to deformation
and aging, but it tends to cause low-temperature cracking. To solve this defect, a novel idea …

We used the nuclear magnetic resonance online detection method to analyze the water
invasion mechanism and residual gas distribution of a carbonate rock gas reservoir. The T2 …

Deep carbonate gas reservoirs exhibit diverse reservoir types and complex seepage
patterns. To study the gas production capabilities of different composite reservoir types, we …

Deep aqueous carbonate gas reservoirs are developed with pores and fractures. The strong
compressibility of rocks and the complex gas-water relationship affect the variation of driving …

Water channeling often occurs in gas wells during the production of fractured-porous
carbonate gas reservoirs with edge/bottom water. A simulation experiment on water invasion …
