Tight reservoirs are mostly developed by volumetric fracturing horizontal wells with the
elastic drive of natural energy in China. As the production of horizontal well decreases …

中国致密油藏多采用水平井体积压裂衰竭式开发, 水平井产量递减快, 一次采收率不足10%.
因此, 有效补充地层能量是致密油藏体积压裂水平井稳产的关键. 注水吞吐是致密油藏水平井的 …

Surfactant-based chemical-enhanced oil recovery (EOR) methods have been recognized to
be effective in both conventional and unconventional oil reservoirs. However, the nanopore …

Subsequent CO2 injection can enhance oil recovery and achieve carbon sequestration in
shale reservoirs, which is crucial for energy sustainability and environmental protection …

Spontaneous imbibition is an important phenomenon in tight reservoirs. The existence of a
large number of fractures and micro-nano pores is the key factor affecting the spontaneous …

Several researchers have investigated the dominant recovery mechanisms among the
wettability alteration and interfacial tension (IFT) reduction during surfactant flooding in …

Closed‐loop reservoir management (CLRM) consists of continuous application of history
matching and optimization of model‐predictive control to maximize production or reservoir …

A relatively large number of pH-sensitive minerals (eg, calcite, dolomite, siderite) and redox-
sensitive compositions (eg, organic matter, siderite, pyrite, and chlorite) are present in gas …

Fluid storage and transport in shale and clay formations is important in many areas of
application, including hydrocarbon recovery from, and waste fluid storing in, these …

Countercurrent imbibition is an important mechanism for tight oil recovery, that is, water
imbibes spontaneously from the fracture into the porous matrix while oil flows reversely into …
