Shale pore evolution has a dramatic influence on gas occurrence and is of great significance for the evaluation shale reservoirs. To better understand nanopore during whole hydrocarbon generation process, thermal simulation experiment, adsorption (N2 CO2), organic geochemistry experiments were carried out. The results show that total volume (PV) specific surface area (SSA) exist in two favorable development periods process with corresponding vitrinite reflectance (Ro) values ∼1.5–1.8%...
The enrichment of organic matter in marine shale is a complex process involving tectonic–sedimentary interactions. tectonic setting exerts critical control over sediment provenance, biota, and subaqueous environmental conditions deposition. To unravel the mechanisms differential controls accumulation shales across distinct regimes, this study systematically examines Lower Cambrian Niutitang Formation Silurian Longmaxi Upper Yangtze Block, SW China. Through comprehensive geochemical analyses...
This study delved into the pore-throat heterogeneity of tight sandstone in Ordos basin for NMR and Rate-Controlled Mercury Intrusion tests (RCMI). The aim present was to qualitatively quantitatively characterize microscopic a pore throat based on merits RCMI. On this basis, effect gas-phase percolation capacity studied by gas-water relative permeability test. As revealed from results, ① difference fractal characteristics same sample is caused different principles range measuring throats two...
The pores in shales are mainly on a nanometer scale, and the pore-size distribution is vital with regard to preservation exploitation of shale gas. This study focuses organic-rich lower Cambrian black Upper Yangtze Platform, South China investigates their TOC, mineralogical composition nanopore structure. Low-pressure N2 CO2 adsorption experiments were conducted at 77.35 K 273.15 K, respectively, structures characterised by modified Brunauer–Emmett–Teller, Dubinin–Radushkevich, t-plot,...
Abstract Mobility is the main factor restricting production of tight oil. In order to explore influence pore throat structure and fluid seepage on mobility, six sandstone samples are selected by high-pressure mercury intrusion, nuclear magnetic resonance, water driving oil experiments, oil-water relative permeability experiments discuss multiphases mobility The results indicate that with increase in effective porosity, more exchanged, phase enhanced. large positively correlated while...
Tight sandstone oil reservoirs in the Yanchang Formation of Ordos Basin have great resource potential. Reservoir quality plays a crucial role aggregation and development tight oil. The is indirectly controlled by diagenesis, which directly manifested differences pore structure characteristics. At present, there are many studies on relationship between reservoir diagenesis Formation, but still no unified method for classifying diagenetic facies types characterizing full-scale structure. In...
Microscopic pore structure and water distribution are important fundamental parameters for coalbed methane reservoir characterisation. These closely related to the calculation/interpretation of other critical parameters, such as permeability flow capacity. In this study, scanning electron microscopy, low-pressure nitrogen gas adsorption, nuclear magnetic resonance spectroscopy, theoretical calculations were used study characteristics Zhaozhuang coal mine in southeastern Qinshui Basin, PR...
Enhanced oil recovery (EOR) provides a significant contribution for increasing output of crude oil. Alkaline-surfactant-polymer (ASP), as an effective chemical method EOR, has played important role in advancing the Daqing oilfield, China. Chemical flooding utilized process ASP EOR produced concerned damage to reservoir, especially from strong alkali ASP, and variations micropore structure sandstones reservoirs restrain late stages oilfield development. Laboratory experiments were conducted...
The exploration and production results of lacustrine shale oil are closely related to enrichment evaluation. However, there exists a lack rapid accurate evaluation methods for strongly heterogeneous shale. In this study, an innovative standard graded is proposed. the standard, considering light hydrocarbon loss oil, free (S1) content corrected hydrocarbons. Moreover, on basis expulsion threshold theory, combined with specific geochemical characteristics in study area, mobility OSI (the...
