Optimum design of developing well network by integral fracturing the compact gas reservoir of the Jurassic Shaximiao Formation in the Xinchang gas field,Sichuan,China;

The volcanic oil reservoirs are characterized by low permeability, deep burial depth, tighter rocks, thick oil-bearing intervals and developed natural fracture and solution pores, and which have some difficulties such as high temperature of reservoir, high pumping pressure, high fluid loss, high fracture initiation gradient and high rate of sand up while fracturing.

The overall reconstruction project of Oil Refining Wastewater Treatment Plant of Jinling Branch of Sinopec Corp.

Design of vector well pattern and optimization of integral fracturing in low permeability reservoir;

Improved integral fracturing numerical simulation for four-spot pattern with horizontal fractures;

In view of Pingbei oilfield has the characteristics of low porosity, low pressure, ultralow permeability and low oil saturation, the integral fracturing technique was performed by combining of fracturing technique with reservoir engineering technology.

From optimization of large-scale fracturing and fracturing techniques, field tests and analysis of its effect, the in filled artificial fracture in chang30-31 block of chaoyanggou oilfield has been mainly discussed which gas gained an ideal results and the primary acquaintanceship and the experience.
