由巖屑形成的 的英文怎麼說
中文拼音 [yóuyánxièxíngchéngde]
由巖屑形成的
英文
detrital-
This is the direct reason of bad reservoir property of sandstone, especially lower permeability. the influence and control factors of reservoirs include : deposition, diagenesis and tectogenesis. the deposition is the basic factor, it control the shape and distribution of sand body, and influence the type and the intensity of the diagenesis ; the diagenesis is the key factor, it control the process of pore evolvement, so the diagenesis control the sandstone ' s storage space and reservoir quality directly ; the fracture of the tectogenesis formation could improve the porosity and permeability of sandstone
其中沉積作用是基礎，控制了儲集砂體的形態特徵和分佈范圍，同時由於不同沉積類型砂體在碎屑成分組成、泥質含量、顆粒粒度、砂體厚度、砂體內部的非均質性、孔隙介質的物理化學性質等方面不盡相同，從而也影響著砂巖所經歷的成巖作用路徑、類型和強度，因此沉積作用是控制儲層發育的主導因素；成巖作用是關鍵，直接決定了砂巖的孔隙演化過程，從而決定了儲層內部儲集空間特徵和儲集性能；而構造作用形成的裂縫對改善砂巖的儲滲性能具有一定作用。This paper sums up characteristics of au anomalies within tertiary red elastic beds in a certain area of qinghai province, and points out that au anomalies mainly exist in the middle part of the tertiary strata, that anomalies are most strong in stream sediments, and that au anomalies result from secondary enrichment of au
摘要對青海某地第三系紅色碎屑巖層中的金異常特徵進行了綜述，指出金異常主要存在於第三系中段巖層中，異常在水系沈積物中強度最大，並認為金異常由次生富集作用形成。Abstract : this paper sums up characteristics of au anomalies within tertiary red clastic beds in a certain area of qinghai province, and points out that au anomalies mainly exist in the middle part of the tertiary strata, that anomalies are most strong in stream sediments, and that au anomalies result from secondary enrichment of au
