A hot water station is set up to heat up desalted water,using the low temperature topping gas oil and stabilized naphtha,thus,good results are obtained in the aspects of steam and power saving.

Laboratory experiment of barrier injection flooding for Lamadian gas cap reservoir.;

The shelter water injection technique study in gas cap reservoir;

For gas cap reservoirs,the oil/gas/water distribution is crisscross,the drive types are so many and the oil/gas/water movement is very complicated.

Numerical simulation of barrier injection flooding for layered gas-cap reservoirs in Lamadian Oilfield;

Study of numerical simulation for gravity drive of crestal nitrogen injection in gas-cap reservoir;

Building the underground gas storage on the basis of the sand gas-cap reservoir of Huabei Oilfield in the water-driving final development stage is of great significance to guarantee the safe and sustainable gas supply to Beijing, Tianjin and Hebei region.

The key problem of gas cap oil field development is how to deal with the interrelation between gas area and oil area, the adopted exploitation strategy is to make the interrelation harmonious.

The gas-cap oil reservoir is an oil reservoir overtopped with gas phase hydrocarbon that is in a unified hydrodynamic system with the underneath oil deposit and the water body.

Modified method for calculating the reserve of reservoir with gas cap using displacement characteristic curves;
