On the basis of analyses of wellbore unstability mechanism,the changing law of shale mechanics parameters was established after shale hydration by the experimentation. 在井眼失穩機理分析的基礎上,經(jīng)室內實(shí)驗得出泥頁(yè)巖水化后巖石力學(xué)參數的變化規律。
Disc area and height were used for calculation of the normalized mechanical parameters.Glycosaminoglycan content was normalized by dry weight. 用間盤(pán)面積及高度對力學(xué)參數進(jìn)行標準化計算,粘多糖的含量通過(guò)間盤(pán)的干重來(lái)進(jìn)行標準化。
