Abstract: Porosity evolution of reservoir is a key and difficult point of the study on hydrocarbon accumulation and regional reservoir evaluation.Diagenesis of low permeability reservoir dominates pore evolution.Through cores,thin sections,SEM and other methods,reservoir characteristics,diagenesis and relationship with physical property of Chang 101 reservoir in the Shanbei area of Ordos Basin were systematically studied,and the diagenetic evolution sequence was established.Combined with burial history,geothermal history and hydrocarbon filling history,pore evolution model were qualitatively and quantitatively studied and porosity of the critical period of hydrocarbon accumulation were restored.The results show that types of reservoir sandstone are arkose and lithic arkose.It is a typical low porosity and low permeability reservoir with an average porosity of 10.21% and an average permeability of 2.88×10-3μm2.The types of pores are inter-partical and dissolution pores with strong heterogeneity.The main diagenesis includes compaction,cementation and dissolution which belong to stage A of middle diagenesis phase according to comprehensive analysis.Original unconsolidated porosity is 35.71%.The process of pore evolution was summarized as:Strong compaction and pore reduction(-19.42%),early stage of cementation and pore reduction(-6.46%),stage of dissolution and pore increase(+3.38%) and late stage of cementation and pore reduction(-2.84%).Also,the reduction rate of porosity by compaction is 54.38%,the reduction rate of porosity by cementation is 26.04%,and the increment rate of porosity by dissolution is 9.46%,indicating early strong compaction is the main reason of low permeability and cementation further strengthens characteristics of low permeability.
