APPLICATION RESEARCH OF CRUDE OIL FINGERPRINT-CHROMATOGRAM CORRELATION ANALYSIS TECHNIQUE IN JIN-16 BLOCK, LIAOHE OILFIELD

This paper presents the principle of the crude oil fingerprint-chromatogram correlation analysis technique. Firstly, establish the original" fingerprint" typical curve graph through analyzing the original fingerprint of the crude oil in a block, then, compares itwith the chromatogram peak of the commingled-produced oil, the contribution of oil in dif ferent layers to the well can be identified. This provides reliable basis for the adjustment of the production measures and the working out of the production plans of an oil well. With the help of it, the oil-produced degree of different layers can be known, which w1ll provide direction for the next production potential tapping. This paper also introduces the calculation software developed by using chromatography, presents the research results of the actual contribution of the main layers of wells Jin2-C5-2l5 and Jin2-6-307 in Jin-16 block to the single well productlvity during the commingled production.
