The Jiyuan Oilfield Long 6 Reservoir In The Evaluation And Development Of Technology Policy Research

This paper is started from the regional sedimentary background, and makes full use of principles of sedimentary,such as lithology sedimentary structure, sedimentary facies sequences and so on, combined with the results of correlation analysis from the log facies and sedimentary facies of study area, makes sure the sedimentary subfacies and sedimentary microfacies of different sublayers by comprehensive study,eventually, through comprehensive evaluation to the reservoir, selects the target zone which is benefit to production and formulates the reasonable development technology policy.In deepening strengthening sublayers, focusing on key wells to determine the detailed classification;To apply the lithological sedimentary structures, phase sequence and other principles of sedimentology, combined with sedimentary facies and log correlation analysis with the results, the study identifies the sublayers of sedimentary subfacies and microfaciesThrough the reservoir characteristics and diagenesis and reservoir characteristics of micro-analysis, combined with sedimentary facies characteristics, migration and accumulation of oil and past gas law and the development of data and exploration wells in the past, evaluation of well test and production test data, a comprehensive evaluation of the reservoir, divided into four favorable abundance zone.Through reservoir numerical simulation and contrastive analysis, combined with the block development actual, we determined the Jiyuan oilfield development methods, water injection time, well pattern, well row spacing and reasonable development of technology policy.
