【 摘 要 】

The parallel reservoir perforating technology enables each shot hole in the gun to be fired in a direction parallel to the reservoir at a set angle, realizing a new technique in which the perforating projectile and the reservoir are parallel. The technology can be combined with the azimuth perforating technology. For the oblique angle of the reservoir and the wellbore, the oil pipe conveying type azimuth perforating technology, the inclined well self-orientation perforating technology and the modular cable perforating technology can be used for construction. The technology can effectively reduce the fracture pressure of reservoir construction, improve the productivity of medium and low permeability reservoir oil wells, and meet the needs of low permeability, thin poor layer and special well development and transformation.
