Prediction of adsorption isotherms under different temperatures is significant to reserve estimation shale gas reservoirs. Based on the Polanyi potential theory and Langmuir theory, a method was presented predict at temperatures. In this method, relationship between pressure temperature quantified. By utilizing we predicted Longmaxi from 45 °C 120 according experimental data 30 °C. Meanwhile, b...

Organic matter (OM), composed of various macerals, has a strong influence on the enrichment shale gas. Nevertheless, connection between OM-hosted pore structure and maceral type is not yet fully understood because difficulty to identify types by traditional scanning electron microscope (SEM). Using combination reflected light microscopy, focused ion beam SEM (FIB-SEM), Raman spectrum, three typ...

Shale plays an important role in the energy industry and enhanced characterization of fundamental properties shale is essential to economic safe exploration this resource. This study investigates elastic modulus, hardness, creep behavior Longmaxi outcrops at different temperatures using instrumented nanoindentation. The results show that as temperature increases from 20 °C 300 °C, approximately...

the hydrolysis of cadmium nitrate was studied spectrophotometrically at different ionic strengthsof sodium perchlorate in a wide ph range, 1-12, and at 25 c. least squares calculations areconsistent with the formation of m(oh)+, m(oh)2, m(oh)3- and m(oh)42- species, which m iscd2+. the dependency on ionic strength in the background electrolyte solutions was taken intoaccount by using a debye-hu...
