气相色谱资料在肇源地区扶余油层定量解释中的应用

Application of Gas Chromatogram in Quantitative Interpretation for Fuyu Oil Bed in Zhaoyuan Area

随着油田开发的不断深入,含水储层逐渐增多,开发井解释的难度越来越大。为经济有效地搞好肇源地区开发井的解释评价工作,开展了利用气相色谱分析资料定量解释评价储层的研究。通过对多块井壁取心样品气相色谱资料进行处理,得到各单个组分参数,结合试油资料,绘制出油水层定量解释评价图版(符合率在90%以上),依据解释图版,得出油水层判别标准,定量地解释评价油水层。该技术可在其他地区推广应用,从而更好地为油田勘探、开发服务。

In the process of oilfield development,water-bearing reservoirs gradually increase and difficulty of development well interpretation increases too.In order to complete both interpretation and estimation for development well in Zhaoyuan area economically and effectively,research on quantitative interpretation to reservoirs is carried out,using analytical data of gas chromatogram.After gas chromatogram data treatment to coring samples of multi walls of oil wells,single component parameter can be obtained.Based on the parameter and oil testing data,quantitative interpretation appraisal plate of oil -water bed can be plotted(coincidence rate>90%).With the assistance of interpretation plate,discriminatory criterion for oil-water bed is drawn for quantitative interpretation and appraisement of oil-water bed.It will be popularized and applied in some other areas,providing better service for exploration and development of oil field.
