Abstract

Abstract: Through largescale threedimensional simulation test, the influence of hole deviation angle, azimuth angle and perforation orientation on opening pressure, position, and extention rule of fracture created in fractured deflected hole is researched. Visual description on opening and extention is achieved under different parameter condition. A way is sought to make a big level fracture by means of directional perforation to reduce the breakdown pressure of formation, improve the shape of fracture and enhance the success rate for deflected hole fracturing treatment. According to it, perforation project and hydraulic fracturing design can be objectively optimized. The experimental conclusion is important to improve fracturing stimulation treatment technology and postfracturing response for deflected hole.

Key words: deflected well, perforation, fracturing treatment, fracture, test
