Daqing Oilfield Sanan Development Zone The Polymer Flooding EOR Potential And The Effective Development Methodology

In recent years, with the development of polymer flooding in SananDevelopment Zone, a class of reservoir Pu Ⅰ been completed to achieve theproduction effectively succeed, by deepening reservoir understanding andoptimization of the layer is a combination of polymer flooding, the implementation ofpolymer flooding potential. Daqing Oilfield ongoing the the polymer flooding EORresearch and industrialization block to put into operation the first oil field, achievedremarkable results in the Portuguese group classes reservoir polymer flooding havemoved into the follow-up stage of waterflood sub-layers of polymer injectiontechnology start industrialization promotion. Research topic of this article, for thesecond-class reservoir characteristics, according to the fine geological research todetermine the block to meet the conditions of the two types of polymer floodingreservoir thickness development, distribution, and heterogeneity; combination ofstrata by deepening reservoir understanding and optimization injector spacing andwell network convergence, the establishment of effective drive system of the polymerflooding, the set of well network after polymer flooding, the return of two types ofreservoirs up and down and the three types of reservoir EOR effective development.At the same time, research to optimize injection and slug combination, determine theeffective development of polymer flooding, a high level of economic and socialbenefits, to further improve the efficiency of polymer flooding development andmaintain Daqing Oilfield continued stable production has an important significance.
