井底压力对岩石破碎的影响机制及应用研究

Mechanism and Application Research of Underground Pressure on Rock Crushing

钻井液井底压力与地层孔隙压力是影响岩石破碎的重要因素,其中的影响机制涉及到地层渗透性、流体密度等一系列因素。DC指数法作为研究这一问题的重要手段,缺少受力方面的内容,无法充分揭示井底压力差与岩石破碎之间的相互关系。基于此,针对井底压力与岩石破碎之间的相互关系展开了研究,建立了影响模型并分析了改进方向,期望对相关从业人员有所帮助。

The pressure and formation pore pressure of drilling fluid and formation is an important factor affecting rock crush.The impact mechanism involves a series of factors such as formation permeability,fluid density,and DC index method as an important means of researching this issue.Lack of content on force,it is impossible to sufficiently stabilizing the relationship between the pressure difference between the rocks.Based on this,this paper is based on the related relationship between ceramics and rock crushing,establishing an impact model and analyzing improvement,expects to help relevant practitioners.
