合采油井产量贡献液相色谱监测法

合采油井各生产层段产量贡献是生产管理中的重要参数,现有测试该参数的技术都存在着成本高、精度低等缺陷。根据不同油层芳香烃分布规律,以及反相液相色谱对芳香化合物良好的分离效果,紫外、荧光检测器对芳香化合物检测的高度选择性和灵敏性,建立了合采油进产量贡献芳香烃液相色谱监测技术。实际监测结果与单层采没实践、试油产量和单抽作业结果相符。

A monitoring technique for production allocation of commingled production well with liquid chromatography

The production allocation in productive intervals is an important parameter to commingled production well management. In effect, current techniques to test that parameter have some. shorcomings, such as high cost, low reliability. Base on the regular distribution pattern of aromatics in different productive interval, and the good fractionation effect of inverse liquid charomatogrphy, and the high sensibility and selectivity of ultra-violet and fluorescence detecting devices to aromatic compunds, a monitoring technique is established in this paper for production allocation of commingled production well with liquid charomatogrphy of aromatics in oil. Actual results correspond to the single reservoir production practice, the test oil yield and the single-in-terval test results.
