Study on treatment process of vapour driving oil recovery wastewater reused for high pressure boiler water supply;

The damage of heavy oil reservoir is related to mineral characters and steam-flood recovery also exerts an influence on it.

The essential technology of steam drive for heterogeneous heavy oil reservoir with edge-bottom water;

Development of insulated tubing for steam drive process;

Optimization of succeeding water flooding plan after steam drive pilot test in Block Qi40;

Study on oil displacement mechanism of pilot test of steam flood in Shanjiasi oil field.;

Through vacuum physical modeling,this paper studies the best injection rate of steam flood with horizontal well in extra-heavy oil reservoir of Fengcheng oil field,Kelamayi oil province, steam injection with different vertical wells, the influence of oil displacement by horizontal well on production result,and the influence of steam flood on reservoir temperature.

For the heavy oil steam flood well groups,some problems are present,such as the quick decline of oil-steam ratio and insufficient steam injecting into the reservoirs vertically or insufficient producing of the reservoirs.

Numerical simulation of steam flooding in Chaoyanggou Oilfield;

Calculation of casing stress of steam flooding wells in Block Qi40;

Foam technology for improving development effect of intermission steam flooding;

Feasibility Study of Steamflooding after Huff and Puff in Millers in Super—heavy Oil Reservoirs and Field Test;

Research progress of steamflooding in light oil reservoir

Based on the analysis of production characteristics of steam soaking and steamflooding in the west block of Region 9 of Gudong Oilfield, the necessity of development mode of hot water injection combined with steam soaking is discussed in combination with the theories of steamflooding steam soak.
