Numerical simulation of thermal-surfactant combination flooding for heavy crude reservoir;

Application of eletrodialysed oilfield effluent water in polymerflooding and combination flooding system;

A study on physico-chemical percolation mechanism of combination flooding system;

Feasibility of the ASP flooding in Northern Putaohua oilfield in Daqing;

Study on relation between interfacial tension and displacement efficiency of ASP flooding;

The lab experiments and oilfield pilot test show that ASP flooding is most practical in Hong Gang oilfield.

Study on chromatographic fractionation effect of three?component compound flooding system in western area of Gudao.;

In view of the fact that the components of compound flooding are complex,at present,it is difficult to simultaneously determine any component concentration by using analytic method of single component sample,the derivative spectrographic method is proposed.

The polymer-surfactant binary combination drive is a low concentration one formed on the basis of de-alkali ternary system,which can greatly enhance the viscosity and elastic of polymer,minimize the negative effect induced by emulsion treatment,totally wipe out scaling of formation an.

An HPLC method for the analysis of surfactant PS concentration in injected produced liquor has been established to meet the need of ASP flooding developed in Gudao West Block of Shengli Oilfield, with a minimum detectable limit of 0.

Using physical simulating experiment methods,this paper studies the kinetic process of the biopolymer solution in ASP co-displacement through- porous media.
