A transient model to simulate the temperature and pressure in CO2 injection wells is proposed solved using finite difference method. The couples variability of properties conservation laws. maximum error between simulated measured results 5.04%. case study shows that phase state primarily controlled by wellbore temperature. Increasing or decreasing rate contributes obtaining supercritical state...

Abstract With the development of gas well exploitation, calculation wellbore with single-phase state affected by single factor cannot meet actual needs engineering. We need to consider simulation complex environment under coupling multiphase and multiple factors, so as better serve petroleum industry. In view problem that commonly used temperature pressure model can only be for conditions, erro...

Avian tumour virus-infected chick embryo fibroblasts express new antigens, identical with the viral envelope antigens, in their plasma membranes. Electron-microscopic examination of carbon-platinum replicas of cells labelled with haemocyanin-marked antibody has shown the distribution of these antigens to be diffuse over the cell surface with an increased concentration on peripheral cell process...

In order to clarify the gas-water two-phase flow law in horizontal wells and study characteristics wells, firstly, a well is numerically simulated analyzed, pattern distribution under different inclination angles phase separation rates obtained. Secondly, series of production logging instruments including CAT instrument was used conduct experimental research on conditions, measured values each ...

The ultra-cold non-interacting Boson gases form so-called Bose-Einstein condensates (BECs). It is desirable to have a rigorous mathematical theory for such quantum phenomenon. In this talk, I will report our numerical and analytical results on the ground state patterns and their phase transitions of spin-1 BECs in a uniform magnetic field. The macroscopic model for spin-1 BECs is a generalized ...
