Intergeration Heterogeneity Study For Hu 123 Of Zhong Yuan Oil Field

The paper makes full use of geological,well-logging and indoor analysis and test data,and integrate well-logging sedimentology,petroleum geology and computer technology with theory of traditional paleontology and sedimentology,according to research thoughts that from macroscopic to microscopic,from single well-Multiple well to target stratum in the research region,have studied the property of microcosmic pore structure,lithologic, sedimentary facies,petrophysical property and so on in-depth.Based on the content describe above,we sort the reservoir into three and evaluate the three types of reservoir,which Supply foundation to progressive exploration and increasing the effective exploitation,ln the end,we achieve the following conclusion:1.Facies of hu123 Oil-bearing bed are lake delta,facies of Hu 123 is delta front and hu123 is delta plain.Sand bodies of hu123 Oil-bearing bed are mainly distributary channel deposits of lake delta front facies and delta plain facies.2.By analyzing the data of drilling cores and rock thin-section,we think that fine-grained feldspar sandstone is the main oil-bearing rock in Hu123 reservoir of research region.3.The results of reservoir heterogeneity study indicate that heterogeneity in Hu123 reservoir of research region is high.4.We evaluated reservoir by petrophysical facies parameter(FZI) and net-pay thickness,and divide reservoir in hu123 of research region into three,namelyâ… (good reservoir),â…¡(medium reservoir),â…¢(poor reservoir),the results indicate thin hu123 reservoir type of research region mainly isâ…¢,hu123 areâ… andâ…¡,hu123 areâ…¡andâ…¢and hu123 isâ…¢..We compare the evaluate results with core and production test data,the results indicate that this method is feasible in container rock evaluation,and is also very scientific and synthetical,it pointed out the direction for the oil exploration and exploitation,and have some economic benefit,so it can be generalized.
