Oil adsorption on the pore surface of tight shale affects the transport and even recovery of oil through shale reservoir. In this paper, an innovative model evaluating the n-alkane adsorption on shale was developed theoretically according to the hydrocarbon vapor adsorption (HVA) process and was verified by the n-decane (i.e., n-C10) adsorption on continental oil shale obtained from the Dongying sag...
Although extensive studies have been conducted on the shale reservoir in recent years, little work has been focused on argillaceous dolomite. In this study, investigation of microscopic pore structure in the argillaceous dolomite reservoir in the Xingouzui Formation from the Jianghan Basin has been undertaken to further the understanding of the oil and gas storage mechanism in these rocks. Based on...
Shale oil resources are found in the argillaceous dolomite in the Xingouzui Formation of the Jianghan Basin. The grading evaluation criteria based on the oil content was established to discuss the shale oil potential. The parameter of hydrocarbon potential index, (S 1 +S 2 )/TOC×100, suggests that the hydrocarbon potential of the argillaceous dolomite becomes lower significantly with...
This study investigated the chemical characteristics of the particulate matter emitted from a diesel engine (Diesel Particulate Matter, DPM) and the correlations between polycyclic aromatic hydrocarbons (PAHs) species as well as between PAHs and inorganic elements in DPM through dynamometer testing. There were six sets of speed–load conditions. Engine speeds varied from 1000 to 1600rpm, while engine...
