The studies of in - layer heterogeneity are as follows : the text depicts the characteristics of heterogeneity by calculating the coefficient of variability, kmax / k and k. max / k. min of sand layers of different sedimentous microfacies ; divides interlayer into two types, and counts their numbers, thickness, frequency and density of a single sand layer according to the characteristics of lithology and logging, finally summarizes the characteristics of interlayer distributing ; sets up five in - layer heterogeneity models and points out that the primary models are model a and c. the studies of between - layer heterogeneity are as follows : the text depicts sand layers " growth and distributing conditions by calculating the lamination factor, sandstone density and overlap coefficient ; makes certain the lithology and thickness of interlayer by the method of contrasting the typical curves
層內非均質性研究，通過計算不同沉積微相砂體滲透率的變異系數、突進系數以及級差來說明主要儲集微相的非均質特徵；據巖性及電性特徵，將層內夾層分為兩類，統計單砂層段內夾層的個數、累積夾層厚度、夾層頻率及夾層密度，並且根據夾層頻率及密度平面分布圖統計出每層的頻率相對高值區和低值區，總結夾層分佈特徵；根據物性參數隨深度的變化趨勢建立了五種儲層層內物性非均質模式，指出研究區內以a型和c型模式為主。Before rock failure, it is found that ae distributed densely, and the coming fracture will occur in the density center of high magnitude events, and ae ratio of frequency grows greatly. these precursors can be presented by the change of b value, a t value and the contour of v value. prefab crack systems in the specimen will affect the fractures hi rocks
關于巖石破裂過程中一些物理量的變化，發現在巖石破裂前，主破裂發生的區域先出現大能級聲發射的密集分佈；在巖石加載的臨界狀態，大能級的聲發射數量大量增加；在接近臨界時，大能級聲發射事件在失穩前頻度突然加快。
