這個巨大的陷穴是由一條地下小河穿過巖石裂縫形成的。The variations in trace element contents and ratios may hold up a mirror to the lake - level fluctuations and climatic changes, which, in turn, have exerted a direct and important effect on the sequence stratigraphic development. collectively, the reservoir rocks from the yanchang formation consist dominantly of the delta front subfacies subaqueous distributary channel and channel - mouth bar microfacies and delta plain subfacies subaerial distributary channel microfacies fine - grained feldspar sandstones and siltstones. the reservoir rocks have been subjected to three stages of diagenetic and porosity evolution : ( 1 ) the porosity reduction by the mechanical compaction and chemical pressure solution during the early diagenetic stage ; ( 2 ) the porosity increase by the dissolution during the a substage of the late diagenetic stage, and ( 3 ) the porosity reduction by the cementation and filling during the b substage of the late diagenetic stage
系統的儲層特徵研究表明，該區延長組儲層成因類型主要為三角洲前緣水下分流河道、河口砂壩及三角洲平原水上分流河道微相細粒長石砂巖、粉砂巖；儲層巖石經歷了壓實，膠結，溶蝕等成巖作用，歷經早成巖機械壓實和化學壓溶孔隙縮小期、晚成巖a亞期溶蝕作用孔隙擴大期及晚成巖a亞期（ b亞期）膠結充填孔隙縮小期三個成巖-孔隙演化階段；儲層物性總體上具有較低孔滲、低孔滲的特點，孔隙類型主要為粒間溶孔、殘余粒間孔隙、粒內溶孔、晶間孔及晶間溶孔，裂縫不發育，儲集巖排驅壓力和中值壓力較高，孔隙結構類型以細小孔-微孔隙，微細喉-微喉型為主。You are looking at a good example of exfoilation, where the cracks happen along the crystaline of the rocks
你正看到巖石片狀剝落的很好例子，裂縫會沿著巖石結晶處產生而漸漸擴大There are various reservoir structure types of the insert salt layers non - sandstone reservoirs in jiangban oil region, mainly including porous type, porous - fracture type and fracture type, and high mineral contents of clay
摘要江漢油區鹽間非砂巖儲層結構類型多，主要有孔隙型、孔隙裂縫型和裂縫型；粘土礦物含量較高；這種儲層主要是泥巖，含盆和白雲石，裂縫發育，並且巖性變化大。2 ) the effects on waves conversion are stronger in rocks with dry fractures than that in rocks with water - filled fractures, and s - waves attenuate more rapidly in rocks with water - filled fractures. 3 ) the explosive point source which locates in anisotropic media can excites not only p - waves but also s - waves. 4 ) the properties of waves propagation were discussed and compared for several point sources with different source functions
結果表明： 1 ）平行排列裂縫造成的各向異性使波前變寬； 2 ）含乾裂縫巖石對波型轉化的影響比含充水裂縫巖石的大，橫波在含充水裂紋中傳播時衰減較快； 3 ）當介質存在各向異性時，爆炸點源產生的波不僅有縱波，還有橫波； 4 ）通過改變點源函數研究不同點源所產生波以及波型的轉換。With artificial neural network to consider affecting the rock to crack in pre - split blasting, people have established the calculation of intelligence model system which can predict and forecast the result and overcome the lack of the theory, model and empirical formula. the system has very great realistic meaning in designing and guiding actual engineering. with the rock ' s crack in pre - split blasting as the studied object, the reason of crack of mineral and rock in pre - split blasting and the parameter design are studied in the paper
