Profile Control Technology Research And Application Of Profile Modification And Oil Displacement In Shen67Block

Block shen67is the high permeability sandstone block. Nearly thirty years of waterflooddevelopment.it is in the period of high water cut.Because under the influence of reservoirheterogeneity,the Reservoir high permeable interval form a water injection.the phenomenonof water injection breakthrough is outstanding.conventional water flooding is difficult to playa good displacement result.The profile control technology as the improvement of highpermeability sandstone reservoir oil displacement efficiency means. At present, has formedthe theory and practical experience of more perfect. Based on the basic situation of masterShen67block, the profile control technology research and pilot test, The technology in blockShen67promotion area application and evaluation of the implementation of the work and theauxiliary measures, The block through the profile control technology application, Absorbentthickness and layers of oil are improved greatly，The single well productivity increase，Evaluation of reservoir parameters change，And since the implementation of the profilecontrol technology，Objective layer implementation of the relative low permeability layersection has been started，Objective layer implementation of the relative low permeability layersection has been started，Increasing production pressure difference method can better improvethe productivity of single well by big pump extracts.Block Shen67profile control for blockeven the successful implementation of the technology provides practical guidance...
