Abstract:

Fingerprints are compounds that appear in between the paraffinon a chromatographof oil. In thepresent work , differentiations were made on the fingerprints of oils from Jurassic and Cretaceous reservoirs in Luliang oilfield, and the cause behind the differences among the fingerprints was analyzed. Formulation experiments were carried about for cases of commingled production from two and three pay zones; computation models of production allocation were established. It is shown that the error between the result from formulation experiments and that from computation models is 9 % and 12 %, respectively, for the two and three pay zones cases. Therefore , the proposed models are valid and can be used forproduction allocation
and production monitoring in thisoilfield.
