巖層壓縮率 的英文怎麼說
中文拼音 [yáncéngyāsuōlǜ]
巖層壓縮率
英文
formation compressibility-
Based on field geological conditions, this paper analyzes the influence law of the bulk factor of filling body on the overlaying strata movement, the stability of key strata and its influence on the overlaying strata movement under the condition of complete fill in goaf, and puts forward the allowable bulk factor of filling body of sustaining strata movement in the rational range
本文結合現場地質條件,分析了采空區全部充填條件下,充填體壓縮率對上覆巖層活動的影響規律,分析了該條件下關鍵層的穩定性及其對上覆巖層活動的影響,提出了保持巖層移動的合理范圍的充填體壓縮率。The study shows that rock stress sensitivity has the following characteristics : rock property has little sensitivity to stress, of which porosity has the least, permeability less, and compression coefficient most ; the rock property decreases with formation pressure decrease ; in the same formation pressure drop, decrease amplitude of the rock property is not a continuous function of permeability but related to distribution scope of permeability
研究得出,巖石的應力敏感性特徵主要有:巖石物性對應力的敏感性總體上不大,其中以孔隙度最小,滲透率次之,壓縮系數最大;巖石物性隨地層壓力的下降而下降;在同一地層壓降下,巖石物性下降幅度不是滲透率的連續函數,而是與滲透率分佈范圍有關,高滲透率范圍,巖石物性下降幅度小,低滲透率范圍,巖石物性下降幅度大。The dissertation researches evolvement and character of formation compression by model test and geology analyzing, based on analyzing transformation of porosity, permeability, compressibility and density of sandstone and mudstone and fracture during subsidence and uplift
本文以模擬試驗和地質分析為主要研究手段,在分析沉降、抬升過程砂泥巖孔隙度、滲透率、壓縮性、密度及裂縫變化的基礎上,研究地層壓力的演化及特徵。It is related to lithology, lithology association porosity, permeability, compressibility of rock, enclosing and fracture etc. therefore, it is important for the forecast of formation compression to consider fully the variation of each geology factor
實際上,地層壓力的影響因素很復雜,與巖性及其組合、巖石的孔隙度及滲透率、壓縮性、巖層的封閉性、裂縫等有關。因此,在進行地層壓力預測時要充分考慮各種地質因素的變化。分享友人
