The Popularization And Application Of The Mature Matching Technology In The Complicated Fault Block Oil Fields

In recent years, oil field development in China is facing the development zone for fromeasy to difficult development zone, from partial to full access to high water cut, high water cut,high recovery degree from including basic balance the serious situation of transition to aserious imbalance and the complexity of the China continental reservoirs, force us to morecomprehensive in-depth research to the reservoir. At present our country most oilfield hasentered high, determining the development stage, composite water cut is more than80%onaverage, only about30%and recovery rate, but there are still50%of recoverable reserves inreservoir. In oil field development after entering high, determining, due to great changes havetaken place in the underground oil and water distribution, the main objects of miningexploration to highly fragmented and local relative enrichment, no longer large continuousresidual oil, and at this point we focus is the space of the reservoir concerned with sex(separated), with low permeability, thin reservoir, interlayer insulation, micro structure andsmall fault and heterogeneity of petrophysical problem, need to study the remaining oil indifferent geological model spatial location, shape, number, or even change over time.New wood oilfield is a complex fault block oil reservoir, the block developmentcontradictions increasingly prominent, complex injection-production relation, thecontradiction in three high dispersion, residual oil, invalid water cycle is serious; Wood blockssouth imperfect injection-production well pattern, formation pressure level is low, the blockdevelopment effect is poorer. To solve these problerms, our factory form five form a completeset of mature technology in recent years, and its popularization and application. On partitionof macro policy under the guidance of water flooding, through the study of the classificationof reservoir management, do a good job of the quantitative stratified water distribution, at thesame time through perfecting injection-production well spacing, implementation cycle waterinjection, profile control experiment, the oil well fracturing acidizing reservoir renovation, toimprove the development effect and slow down the decline rate, the oilfield has realized theold oilfield continuous production.
