A RESEARCH OF THE BASIC PRINCIPLES OF JETTING DRILLING FRACTURING WITH RELATION TO SOME FACTORS

Sun Xuezengand;Li Bangda Teaching Unit of Drilling  
Using bydrodynamics and the theory of rock strength, the paper analysesthe basic principles of jetting drilling rock fracturing, and establishes themathematical formulas for calculating the hydraulic fracturing rock depthand the rate of deviation change for different rock properties, jet hydaulicparameters, the bottom pressure and jetting angle, etc. The research cert-ainly is of great significance to the mastering ability, to the hydraulicfracturing, jetting drilling building angle and simplifing the technologyfor drilling well.
