中文摘要：
苏里格气田盒8段储层经历的成岩作用主要有压实作用、胶结作用、溶蚀作用等,它们各自对储层物性施加不同程度作用。通过定量计算5个成岩作用强度参数,详细分析成岩作用的定量特征及其对孔隙减小的效应。研究区视压实率普遍大于70%,视胶结率全区大于90%,成岩综合系数为0～20%,成岩减孔率为60%～90%,视溶蚀率普遍大于90%,这5个参数表明研究区储层以强压实、胶结作用和强溶蚀作用为特点。
英文摘要：
The diagenesis that He 8 reservoir had come through in Sulige gasfield mainly was compaction,cementation and denudation,which applied the different effects on the physical characteristics of the reservoirs,respectively.Through the quantitative calculation of 5 intensity parameters of diagenesis,the impacts of diagenesis on the physical property of reservoirs were analyzed in detail and their effect on the reduction of porosity.In the study area,the visual compaction rate is commonly larger than 70%,visual cementation rate is larger than 90% in whole area,and integrative diagenesis coefficient is 0~20%,and diagenetic pore reduction rate is 60%~90%,and visual dissolution rate is commonly larger than 90%.The five parameters indicate that the reservoirs in study area have the characteristics of the intense compaction,cementation and intense denudation.
