The paleochannel characteristics and formation condition in the Zhongguai area of Junggar basin

In view of difficulties on control of fracture during fracturing, we developed a new bidirectional agent, and carried on researched on its control mechanism of different agent concentration on fracture control in laboratory, which showed that bidirectional agent can increase 3 -4MPa stress on barrier. Based on this experiment, we combined vertical stress contribution with 3D software, designed fracture scheme of control fracture height, which has been applied to 30 times and achieved good effect
