The fracturing technology and mechanism research of natural fracture and tight reservoir of Tuoshi Oilfield;

Application of separate layer fracturing technology for stuck sealing;

Analyzed inadaptability of fracturing technology to infill well,provided a method by using balance protection fracturing technology to produce thin oil layer with high water cut,and bridge fracturing technology to produce large interval thin oil layer.

Improvement method for the fracturing technique of the low permeable oilfields in the West of Daqing Placanticle;

Therein the hot fracturing technique was first developed within China.

Some fracturing techniques suited for the reservoir are introduced in the paper.

Actually, hydraulic fracture technology has now matured at abroad and home, but the approach of quality control over the field construction of technology needs further perfecting.

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.
