| 摘 要： | 为解决准噶尔盆地腹部沙窝地、莫西庄和征沙村三地区下侏罗统三工河组砂岩储层物性—含油性差异大及控制因素不清的问题，本文通过岩芯描述、铸体薄片和扫描电镜分析，依据物性数据及压汞资料，对研究区三工河组储集空间特征、孔渗特征及孔喉结构特征进行了详细的研究，通过隔夹层分析、岩屑成分及含量分析、成岩特征研究等方法探讨了制约研究区三工河组储层物性—含油性关系的主控因素，研究表明沙窝地和莫西庄小区三工河组储层埋深相对较浅，主要以中粗孔喉和较细孔喉的原生（残留）孔隙为主；征沙村小区埋藏较深，以细孔喉和微孔喉的次生孔隙及裂缝发育为特色。在此基础上探讨了三工河组储层物性的控制因素，研究认为埋藏深度为影响储层发育的主要因素；沉积微相和砂体成因类型为控制储层发育的基础；低地温梯度延迟了压实效应等，有效保存了原生孔隙；塑性岩屑含量、储层的隔层和夹层因素，即储层的非均质性在某种程度上影响砂体的储集性。

| Abstract: | In order to solve the problem of the difference in physical properties and oil-bearing of sandstone reservoirs in the Lower Jurassic Sangonghe Formation in Shawodi, Moxizhuang and Zhengshacun in the abdomen of Junggar Basin.Methods: Based on the physical property data and mercury intrusion data, the spatial characteristics, porosity and permeability characteristics and pore throat structure characteristics of the Sangonghe Formation in the study area were analyzed in detail with scanning electron microscope analysis.The study of diagenetic characteristics and other methods explored the main controlling factors restricting the relationship between the physical properties and the oil-bearing properties in the study area.Results: The primary pores with medium and coarse pore throats and finer pore throats are the main ones; the Zhengshacun community is buried deeper, and is characterized by secondary pores and cracks with fine pore throats and micro-pore throats.Conclusions: The study concluded that the burial depth is the primary factor affecting the development of the reservoir; the sedimentary microfacies and the genetic type of sand bodies are the basis for controlling the development of the reservoir; the low geothermal gradient is delayed the compaction effect and effectively preserved the primary pores; the content of plastic cuttings, the barriers and interlayers of the reservoir, and diagenetic factors, that is, the heterogeneity of the reservoir affects the reservoir performance of the sand body to a certain extent. |
