The Four Properties Of Glutenite Reservoirs And The Classification Of Oil Layers In Hong 003 Well Area

Based on the principles of reservoir petrology,geostatistics,reservoir geology and development geology,the application of statistical features,study of relational characteristics,interpretation model Research methods,the study of the reservoir area of the relationship between the Four-property Relationship,and the oil layer was a detailed division,to obtain the following main achievements and awareness:The relationship between lithology and electrical properties is analyzed,and the lithologic characteristics of the reservoir are summarized according to the logging data of the core and the cuttings.The migration distance of the rock particles is far away and the sedimentary environment is not obvious.According to the relationship between the resistivity log Rt and the acoustic time difference log,the relationship between AC and lithology can be used to establish an explanatory model.Compared with the existing lithospheric and lithologic lithology and interpretation models,it is good.The relationship between physical properties and electrical properties is analyzed.The results show that the relationship between reservoir porosity and permeability is relatively obvious and the correlation is relatively high.The porosity permeability difference of reservoirs is relatively large;the relationship between reservoir porosity and density logging Obviously,the results of the interpretation will be compared with the results of the experimental study of the core rock,and good correlation characteristics are obtained.The results show that the oility of different lithology is different.The mudstone and muddy siltstone are oil-free and the siltstone has a low oil content.For the fluorescent,oil spots;sandstone class oil level higher,and sand and gravel oil level for the majority of oil spots and oil immersion.According to the relationship between porosity,permeability and oility,the lower limit of reservoir porosity is 18%and the lower limit of permeability is 46mD.Oil and electrical properties,the result is the lower limit of the reservoir resistivity from the original 17?.m increased to 20?.m.The analysis of the effective thickness interpretation plate shows that the distribution range of the oil saturation is very wide in the range of porosity distribution.According to the reservoir classification standard,the oil layer is divided into four types according to the different physical properties.The porosity is more than 29%,the permeability is 1000 mD?5000mD,the oil saturation is more than 55%,the class ? is Porosity greater than 25%to 29%,permeability of 300 mD?4000mD,oil saturation greater than 55%;? class of porosity of 22%to 25%,permeability of 100 mD?2200mD,oil saturation greater than 55%;? The oil layer is 19%?22%porosity,permeability 40 mD?1000mD,oil saturation greater than 50%.The effects of the four types of reservoirs on the yield characteristics were analyzed as follows:grade ?,elass ?,? and ?.The results are as follows:the four types of reservoirs are characterized by single peak states,which are single-peak partial and near-symmetrical distributions,and the main intervals increase in succession.The median distribution of various reservoirs increases,0.92 m,2.80 m,2.64 M,3.12 m.The distribution of the plane is characterized by the fact that the distributions of class ? are relatively sporadic and have poor slice,and the distributions of ?,? and ? are well distributed in the extensional and extensional zones of the north-south direction.
