【摘要】 本文应用流体动力学和岩石强度理论,对水力冲破岩进行了机理分析,并建立了用于计算在不同岩石性能,射流水力参数,井底压力,冲蚀角度等参数的水力冲破岩深度和造斜率的数学表达式。这对掌握水力破岩能力,水力冲造斜,简化钻井工艺有一定的指导意义。更多还原

【Abstract】 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.更多还原
