The underground geological conditions in the Shaxi area are complex,and environmental factors have a great impact on the logging work,which leads to certain difficulties in reservoir evaluation.Based on the work done by the previous authors,this paper summarizes the reservoir geological characteristics of the E₃¹ section of the Shaxi block,conducts reservoir quantitative evaluation and reservoir classification evaluation,and finally determines the reservoir classification scheme and establishes quantitative classification.standard.Firstly,the paper collected the basic data,collected the geological,sedimentary and logging data of the E₃¹ section of the Shaxi block,and then carried out a preliminary analysis of the reservoir geological features.After completing the basic logging interpretation work and the pretreatment of logging data,the lithology of the reservoir is analyzed according to the response characteristics of the logging curve.Based on this,the reservoir characteristics are roughly understood and according to the reservoir characteristics.A simple analysis of the four-property relationship of the reservoir is made.According to the existing reservoir data of the study area,the method suitable for the region is selected to calculate the reservoir parameters.By comparison,it is found that the compensating acoustic wave has a good correspondence with the core porosity,find the quantitative relationship between the two and calculate the porosity;find the quantitative relationship between the porosity and the permeability and calculate the permeability according to this;use the Archie formula to calculate saturation.The capillary tube pressure method was used to study the pore structure characteristics,the pore structure parameters were determined,the reservoir quality factor RQI comprehensive classification parameters were established,and the reservoir classification scheme was determined by combining mercury intrusion and oil test mining,and the reservoir was divided into I.,II,III,IV four levels,and establish quantitative standards.The results obtained in this paper can help reservoir division and reservoir quantitative standards to a certain extent in the face of reservoir reservoir classification work with complex underground geological conditions.
