渤海油田高显示出水层地质成因及流体评价新方法OA
Geological genesis of good display layers containing with water and its new method for fluid evaluation in Bohai Oilfield
高显示出水层的流体评价是近年渤海油田勘探面临的难题之一,以高显示出水层实钻井筒资料为基础,参考区域性地质认识,采用横向井间对比、纵向层间对比及层内非均质性对比等方法,归纳总结出残余油、氧化重质油和束缚油为高显示出水层地质方面的三大成因.并依据气测全烃、岩石热解与核磁共振录井技术的各自优势,选取其敏感参数及派生参数,从储层物性、原油性质、总烃量三个维度,建立了规律性、适用性较强的三维立体评价模型及解释标准.实际应用证实高显示出水层解释符合率由50%提高到95%左右.
Fluid evaluation of good display layers containing with water is one of the challenges faced by Bo-hai Oilfield exploration in recent years.Based on its actual drilling wellbore data and regional geological un-derstanding,methods such as transverse well correlation,longitudinal interlayer contrast and in-layer het-erogeneity comparison are used to conclude that residual oil,oxidized heavy oil and bound oil are the three major geological causes.According to the respective advantages of gas measurement of total hydrocarbon,rock pyrolysis and nuclear magnetic resonance logging,sensitive and derived parameters were selected to es-tablish 3D evaluation models and interpretation standards with strong regularity and applicability from three dimensions:reservoir properties,crude oil properties,and total hydrocarbon content.The actual application proves that the interpretation coincidence rate of good display layers containing with water increased from 50%to 95%.
