摘要： 利用普通薄片、铸体薄片、扫描电镜、物性分析、测井解释和粒度分析等资料,对松辽盆地大安油田下白垩统泉头组四段特低渗—超低渗储集层成岩作用类型、成岩作用强度及其影响因素等进行了研究。结果表明:(1)压实作用是导致大安油田泉四段特低渗—超低渗储集层物性变差最主要的成岩作用。研究区储集层压实程度为中等,压实破坏程度与储集层复合砂体厚度、分选系数、泥质含量等参数具有较好的相关性。(2)胶结作用是研究区储集层物性变差的又一重要因素。区内胶结作用强度较弱,胶结作用减孔率与相对构型界面的位置、石英绝对含量、碎屑组分含量和杂基含量等因素具有明显的相关性。(3)溶蚀作用对区内储集层物性的改善程度相对较小。溶蚀作用增孔率与复合砂体厚度、杂基含量具有一定的相关性。压实、胶结、溶蚀作用对储集层物性改造程度影响因素的分析结果,反映砂体的垂向叠置关系、河道厚度规模、水动力强度等沉积特征对成岩作用类型及其强度有一定的控制作用。

Abstract: The diagenetic types,intensity,and the influence factors of extra-low to ultra-low permeability reservoirs of the Member 4 of Cretaceous Quantou Formation in Da??an Oilfield are analyzed by using data of thin section,casting thin section,SEM,physical properties,logging explanation and particle size analysis. The results show that:(1)Compaction is the dominant diagenesis which leads to the loss of the pore. The compaction degree is medium,which has a good correlation with the compound sand thickness,sorting coefficient,mud content etc.(2)The carbonate cementation is the second important factor for the poorer physical properties of reservoirs. The cementation degree is quite weak,and the decrease of the porosity caused by cementation is related to the distance from the reservoir to the configuration surface,quartz content,clastic component content and matrix content.(3)The dissolution degree is relatively weak,which can improve the physical properties of the reservoirs. The increased porosity ratio by dissolution has a certain correlation with compound sand thickness and matrix content. The influfence degree of compaction,cementation and dissolution on the physical properties of reservoirs can reflect that the vertical superimposition relationship of sand bodies,thickness of channels,and hydrodynamic intensity can affect the types and intensity of diagenesis.
