摘要
基于原油色谱指纹技术的原理,对鄂尔多斯盆地五里湾一区中生界长6层原油色谱指纹进行分析与对比,首次将原油色谱指纹技术应用于长庆油田五里湾一区分层产能监测。利用单层原油色谱指纹差异,结合室内不同比例的原油配方,建立了研究区二元原油配产模型,求得混层开发井中长61、长62层的产能贡献。研究结果表明,原油实际配方与色谱指纹计算的最大误差为4.66%,配产模型较为可靠,可以为油田进一步开发提供依据。
The gas chromatography fingerprint technique was applied to monitoring individual zone production allo- cation of commingled oil wells of No. 1 Wuliwan area for the first time. According to the laboratory test on the oil proration, the oil production proration model was established based on the chromatographic fingerprints character of single layer. The individual zone production allocation of chang 61 and chang 62 in commingled oil wells were stud- ied. The maximal error between oil actual formula results and showed that the production allocating model was reliable and has fingerprints calculation was 4.66%, the results potential to be used in oil field exploitation.
