碎屑成分 meaning in Chinese

clastic constituents

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
其中沉积作用是基础，控制了储集砂体的形态特征和分布范围，同时由于不同沉积类型砂体在碎屑成分组成、泥质含量、颗粒粒度、砂体厚度、砂体内部的非均质性、孔隙介质的物理化学性质等方面不尽相同，从而也影响着砂岩所经历的成岩作用路径、类型和强度，因此沉积作用是控制储层发育的主导因素；成岩作用是关键，直接决定了砂岩的孔隙演化过程，从而决定了储层内部储集空间特征和储集性能；而构造作用形成的裂缝对改善砂岩的储渗性能具有一定作用。
