The Technology And Application Of Comprehensive Adjustment In Ultra-high Water Cut Period Of LAMADIAN Oilfield

After ultra-high wter cut phase in LAMADIAN Oilfield, Being faced with high synthetic water cut,Tiny difference of water cut in series of strata ,High degree of developed producing reserves, High recovery of exploitable reserve, low balanced coefficient of reserve-production, And remaining oil is highly scattered , The Cost input are increased rapidly. The further development becoming more difficult. Based on this problem, We selected the typical block of LAMADIAN Oilfield In 2003-2005 year, Combined status in quo and Development trend of Each branch of subject, Synchronously pushes on each research work, Such as Technical development,Person with ability trains,Data preparations,The computer software and hardware environment constructed,Fine study of reservoir,Establish the train of thought of reservoir multidisciplinary further development analysis and objective of tackle key problem, Combining the fine geology research with reservoir modeling,Gives first place to deposit unit and individual reservoir On vertical,subdivision of reservoir lengthways,based on microfacies and geologic model on plane, It truly reflect the distribution law of sand body, Realize fine geologic research deepen ,Forming the practical technologic modeling, Solving problem of gas sand modeling with microfacies control , Make clearly the high water cut position of typical block, pressure field and remaining oil distribution law Pass through the numerical simulation, Make clearly abundance zone of remaining oil, put the synthetical adjust scheme to individual well and individual layer, After these schemes are put into effect one after another, Testing block development situation turn better clearly, Realizing water cut is not risen and crude output is not fallen in 2 years, Procure better economic benefit .
