With the popularization of natural gas and requirement environmental protection, development utilization are particularly important. The status in China’s oil exploration is constantly improving, country pays more attention to exploitation gas. tight sandstone Upper Paleozoic Ordos Basin has characteristics low porosity, permeability, large area concealed reservoirs. increasing demand for China...

The article discusses the issue of resource potential tight terrigenous gas-saturated reservoirs, which lie at significant depths within central part Dnipro-Donetsk oil and gas-bearing region, ways to solve problems related methods development these deposits, since they are non-convective cannot be extracted by classical method. Within scope this issue, considers method hydraulic fracturing as ...

The precise and quantitative characterization of reservoir properties is the key to efficient development tight oil reservoirs. In this paper, taking Chang 8 Member Yanchang Formation in Shuimogou area southern Ordos Basin as an example, sedimentary facies types, microscopic pore structures, diagenesis, influencing factors physical properties, hydrocarbon enrichment law reservoirs are systemati...

Large gas reserves have been found in the Permian platform margin of Kaijiang-Liangping area Sichuan Basin SW China. They are assumed to be a widely developed reef–shoal reservoir. However, tight matrix reservoir cannot support high production using conventional development technology at deep subsurface. In this contribution, we analyze fractured reservoirs along strike-slip fault zones compile...

As for the tight sandstones, pore-scale fluid flow ability is one of most fundamental parameters that determine potential development capacity when compared to conventional reservoirs due relatively tiny spaces. The determination pore-throat structures and their impact on behavior could improve forecast development. Therefore, main purpose this paper study effects differences in microscopic por...

The existing volumetric approach was honored by considering the effects of oil and gas saturations on the evaluation of geothermal resources in oil and gas reservoirs. The main reason to do so was that oil and gas phases may not be simply substituted by water because the values of the specific heat of oil and gas are smaller than that of water. We selected an oil reservoir, Hexiwu, from Huabei ...
