The experimental study on the effect of extraction and increasing permeability by High-pressure Water Infusion in the Long Drilled;

The paper had a comprehensive investigation on the gas pre-drainage results of each borehole group.

The effect of gas drainage is not good at present in China.

In order to improve the collection effect of wild Osmia,effects of different types of houses and times of collection on collection effect were performed in this test.

In this paper, a series of improved thermal recovery techniques during the exploitation of this super heavy oil reservoir is introduced, and good production effect is achieved after the oil reservoir is put into overall productio
