The Research & Development of Horizontal Well Fracturing Technology
The horizontal well fracturing technology is becoming an important manufacturing measures in relieving reservoir damage, and in developing reservoir of low permeability with great efficiency. Based on the horizontal well fracturing process and the effect of factors conceming fracturing research, the level of short horizontal well fracturing is relatively simple and has been quite mature, while long horizontal well fracturing pressure must be taken cracking way to ensure the success of fracturing and fracturing effect. Sub-horizontal fracturing technology is the key tools and the technology of staged fracturing and multi-string packer, a multi-stage fracturing technology and supporting tools for the reservoir to help construction safety and improve the fracture. Owing to the limits of the general length of the crack pressure, hydraulic fracturing technology as complementary tools for jet limit, is more suitable for thin sub-horizontal fracturing, while shooting thick horizontal blowout fracture, the relevant tools need improvement. In addition, the chances for success is also affected by fracturing the rock mechanical properties, stress, shaft stress fracture initiation, elongation, fracture design advantages and disadvantages and other factors.
