摘要
地层破裂压力预测不仅是钻井工程设计的基础,更是油气田经济高效开发的保障。影响破裂压力的因素较多,与地层岩石弹性性质、孔隙压力、裂缝发育状况以及地应力等因素有关。国内外在该参数的计算方面研究较多,很多研究人员提出了很多不同的计算方法,并且大量应用于现场实践中。国外具有代表性的两种模式为Hubbert-Willis模式和Haimson-Fairhurst模式、三种计算方法包括伊顿法、史蒂芬法、安德森法。国内主要有以黄荣樽为代表的一系列学者,通过改进模型、增加参数,建立了适合我国复杂地区的计算方法。经过大量的实践和应用表明,地层破裂压力的预测在钻井工程和储气库评价和建设过程中起着极其重要的作用,是一个非常重要、不能忽视的参数。
Prediction of formation fracture pressure is not only the basis of drilling engineering design,but also the guarantee of economic and efficient development of oil and gas fields.There are many factors that affect the fracture pressure.It is related to the elastic property of rock,pore pressure,fracture development and in-situ stress.In terms of calculation methods of formation rupture pressure,many domestic and foreigr scholars have proposed calculation methods,and they are widely used in field practice.During which,there are two representative models abroad:Hubbert-Willis model and Haimson-Fairhurst model,and three representative calculation methods,including Eaton method,Stephen method,and Anderson method.By iuproving the model and adding parameters,a series of domestic scholars,represented by Huang Rongzun,have established a calculation method suitable for China's complex areas.A large number of practices and applications have shown that the prediction of formation fracture pressure plays an extremely important role in the evaluation and construction of drilling engineering and gas storage,and is a very important parameter chat cannot be ignored.
