A STUDY AND APPLICATION TO ARITHMETIC OF PRODUCTION ALLOCATION OF MULTILAYER COMMINGLED PRODUCTION

Aim at the localization of the technique of gas chromatographic fingerprint,which is difficult of being applied to commingled production of three and more layers oil.The authors study and application an arithmetic of artificial nerve network.It has higher precision,and it is nonlinear and applicable to commingled production of more than three layers.Applying this arithmetic,through the analysis of whole hydrocarbon gas chromatographic fingerprint of crude oil in the laboratory,and pick out some characteristic fingerprint which reflect the character of crude oil in single and commingled layer,Setting up characteristic fingerprint data base,and then analyzing and processing them with ANN arithmetic,finding the rules,then the authors apply the arithmetic to the Lamadian and the Saertu oil field.As a result,even to the problem of more than three layers,the results also have high accuracy,and are close to the MFE test results.The application of the arithmetic offers a economical and applied path to production allocation calculations of multilayer commingled production with the geochemistry means.
