Geological Characteristics And Development Regularity Study Of Thin Superposition And Heavy Oil Reservoir In Du66

This article outlines the Du66profiles and exploration and development history,introduces in detail the reservoir geologic characteristics from the aspects of reservoir ofsequence stratigraphy, tectonic and sedimentary characteristics, reservoir characteristics,interbed development, oil-water distribution, fluid properties, oil-water distribution andreserves calculation. Through a large number of statistical data, during the process of handlingthe block in the week capacity, production days, periodic output, steam injection, oil steamratio, comprehensive water, water storage rate, decline rate, pressure changes and changes ofdaily oil production cycle was analyzed.At the same time, application of steam injectionprofile, fluid production profile, C/O ratio,he remaining oil and mining the extent of therelationship, heating radius theories analysis of the vertical and horizontal reservoir. highrecovery, vertical producing degree of inequality, the downhole conditions and low energyand other issues existing in the handling process were analyzed in detail,and apply sortingNote,overhaul sidetrack and other series of technology means from the vertical andhorizontal to start to improve reservoir development effect, production do reasonable injectionand production parameters, clear throughput law, to speed up the the late heavy oil reservoirsthroughput capacity to take over the technical field test.Field application results show that thestudy of Shuguang Oilfield thin interbedded heavy oil development has a positive and guidingrole, fire flooding technique is suitable for the Du66reservoir development needs, providedirection for further improve reservoir oil recovery.
