The volcano rock is usually located in the area which has experienced intense tectonic movement, led to complex lithology, diversification of lithofacies, reservoir heterogeneity seriously and so on.Due to above reasons, volcanic reservoir distribution is easy to be affected and is difficult to predict. This article argues that wave impedance and density are the sensitive parameters of volcanic rock favorable reservoir in Yingcheng formation by analyzing volcano rock reservoir sensitivity in Yingshan area........

Presence of salinity 9 to 20 g/L of chlorides can cause osmotic stress or inhibit the reaction pathways in the organic degradation process. It results in a significant decrease in biological treatment efficiency or biodegradation kinetics. Research is carried out using glucose–glutamic acid and domestic wastewater to evaluate the amendment of chlorides on biodegradation of sewage at 20°C........

Abstract:After entering the high water cut stage, the remaining oil content depends on the micro pore structure of the complex, the micro pore structure research is also limited to the core laboratory stage mainly, therefore the use of logging data analysis and identification of micro pore structure is the only way for the study of residual oil.The results show that as a nonlinear method, artificial neural network can better simulate the actual strata, and can better identify the complex microstructure of the formation........

Seismic wave velocity is one of the most important parameters in the process of seismic data processing and interpretation, which is significant for calculating the near-surface statics, migration, predicting rock parameters and reservoir inversion. The full waveform inversion(FWI) is recognized widely as a kind of high precision, multi-parameter inversion tool, so it plays an unique advantages role in the velocity modeling........

Coupled, parallel flow of fluids with viscosity stratification through two porous layers is initiated in this work. Conditions at the interface are discussed and appropriate viscosity stratification functions are selected in such a way that viscosity is highest at the bounding walls and decreases to reach its minimum at the interface. Velocity and shear stress at the interface are computed for different permeability and driving pressure gradient.

The problem of laminar flow through a porous medium, with constant permeability, behind a two-dimensional grid is revisited in order to introduce permeability variations in the governing equations. Expressions for permeability profiles are derived when the model equations are linearized and permeability is calculated at the stagnation points of the flow and conditions on the parameters involved in the exact solution are stated. This work might be of interest in the stability analysis of flow through variable permeability media.
