Research On Evaluation Technology Of Old Well Re-Examination Of Jilin Oil Field

Review technique on the old well is always an important and challenging work.Accurateevaluation of residual oil for old wells plays a very important role in late development stageof oilfield adjustment implementation. After years of groping study,China’s oil workersstudy multiple existent well reviewing evaluation technology.Old wells reviewing andevaluating technology have become from an single subject analysis to integrated use ofresearch direction multi disciplines.At present，the review technique on old well is vary,alsothe development speed is also very quick.According to The big qing field in two section of the geological tectoniccharacteristics and the research of predecessors of existent well review evaluation technology,this paper put forward to the integrated data reviews of mud logging, logging, oil test,and thenlooking for suspicious oil and gas layers.To be first, according the datas of oil field drillingand logging to establish lithology database and new four property relationship.According tothe area of well logging curve standardization. And then make the reservoir lithology andOil-bearing lower limit standard,reconsidered on the part of the potential layer interpretationconclusions, make further increase on the new potential geological reserves.Secondly,according comprehensive logging,logging, oil testing,fracturing results, test oil well, layer todetermining refracturing wells and layers.Basing on the geological structure, review on thearea of low resistance oil layer with high water resisting layer and find parts of low resistivityreservoir.The research results in this paper play an important role in the residual oil distributionregularity in the big qing green two field Prediction of remaining oil enrichment area has acertain value use and a very good application prospect.
