The sedimentation is the foundation, affecting the basic pattern of the reservoir, and the sedimentary facies zones beneficial to the formation and evolution of the reservoir includes platform edge bank facies, introplatform point beach facies and acclivity sedimentary facies, etc. ; the diagenesis is the key factor, determining the pattern and scope of the final distribution of the reservoir and being of great influence on reservoir structure, and the diagenesis of promoting the formation of storage rooms is mainly the dissolution occurred during hypergene stage and burial stage ; and the tectonism is the condition of influencing the connectivity among various reservoir bodies and among the storage rooms within a single reservoir body
該套儲層是在4億年左右的地質歷史中,由沉積、成巖和構造作用相互影響而形成的最終成果:其中沉積作用是基礎,影響著儲層的基本形態,有利於儲層形成與演化的沉積相為臺地邊緣灘、臺內點灘和上斜
坡等沉積相帶;成巖作用是關鍵,決定了儲層的最終分佈形態和范圍,對儲層結構的影響至關重要,促進儲集空間形成的成巖作用主要有表生期和埋藏期的溶解作用;構造作用是條件,影響著各儲集體之間以及單一儲集體內部儲集空間的連

The reproductive characteristics and population structure of artemisia ordosica, hedysantm scoparium, caragana korshinskii and the reproductive characteristics of annual plants eragrostis poaeoides and bassia dasyphylla were observed in shapotou artificial revegetation area. stability of the artificial vegetation was appraised from the views of its persistence and variability under local natural condition. the study showed that : the artificial - natural vegetation built with sandbreaks and plants is stable in shapotou area
