An error in closure stress measurement can lead to a significant error in the estimation of the net pressure and, consequently, the fracture geometry.
闭合应力测量的错误会对净压估计,以及随后的断裂几何形状的估计造成严重的错误。
To strong stress sensitivity formation, low BHP reduces pore fluid pressure of near wellbore are which results in the closure of formation fracture.
对于应力敏感性强的储集层,过低的井底压力降低了近井地带地层的孔隙流体压力,导致裂缝趋于闭合。同时,井壁失稳的可能性也大。
