Comprehensive Treatment Plan Oil Region In Qujiaogou

As the extension of water injection development time, a lot of problems gradually. The well water cut rising, single well oil production gradually reduce; Some oil Wells have been flooded water breakthrough; Casing damage and variant of oil and water Wells multi-port; Imperfect injection-production corresponding; Reservoir water is not uniform; Pattern is not perfect; Low degree of oil well work; In order to solve many problems in the area that we have produced, restore the normal production and flooded well increase capacity in low pow, comprehensive treatment project in the area of research.This text set about from the development dynamic, through the dynamic analysis of water injection, illustrates the effect of water flooding, made clear the main factors influencing the block development effect, on the basis of the research work area of remaining oil distribution characteristics and laws, and put forward the direction of remaining oil potential in:(1) through excavating remaining oil potential transfer oil well;(2), perfecting injection-production relation between expansion of plane and vertical sweep volume, increase the degree of water drive with potential;(3) improve the filling hole increase the single degree of reserves control, and improve the development effect of potential;(4) the potential of high water cut regional adjustment of injection-production structure. Improving and perfecting injection-production relation between water flooding control reserves and narrow spacing adjustment for improving water flooding development effect.
