Reserve Evaluaiton And Reservoir Studies Of Liu Maoyuan Block

Yan’ari group of Jurassic and Yanchang group of Tirassic and Jurassic are the purposereservoir groups of oil and gas exploration in Jiyuan area of Dingbian Oilifeld,which is locatedat middle west of Yishan slope" The characters of sedimentary cycles include sedimentary andreservoic characteirstic and vertical rhythm and vertical distribution properties ofhydrocarbons.In this paper, the wirter gained the sedimentary rocks development, structuralcharacteirstics and the evolution, sedimentary facies and sedimentary environmental, reservoirdescription and reservoir characteirstic of Liu Maoyuan, according to study and analysis of itsreservoir breeding actuality combining with logging data，oil production test, and core slice,SEM，etc. Reserves estimation, the major oil-beairng layers of sand distirbution, reservoirproperties，dcpositional system, reservoir-cap, erservoir traps in natuer, was studied thus theassessment of reserves, according to the cross-sectional view drawn to study the reservoir areaand the controlling factors of reservoir cirteira for the classification, analysis and judgmenttarps blocking condition, formation pressure and temperature, and to determine the types oftraps and elements, reservoir capacity and so on.This article evaluated water injection scheme deployment and forecasted index indestination oilfield based on the sedimentary characteirstics, reservoir distribution andoil-water relations, well spacing, and vertical reservoir layer.
