应用录井技术定量评价油气层方法探讨

THE DISCUSSION ON QUANTITATIVE EVALUATION OF HYDROCARBON ZONE BY MUD LOGGING TECHNOLOGY

通过对复杂油气水层识别评价技术攻关，形成了轻质油层、残余油水层、高含泥储层、气水层识别评价等评价技术体系。在此基础上，将录井、测井资料有机结合，研究总结出轻质油层、稠油层、残余油水层等油气水层综合定量评价方法。这些评价方法之间具有优势互补性，其综合应用弥补了单项录井技术在油气层解释评价方面的不足，有效地解决了疑难储层评价问题，提高了油气层解释评价的准确性，在大庆油田勘探开发中见到了明显的效果。

Through dedicated hardwork and researches on complicated oil/gas/water layers identification and evaluation, the evaluation systems were established for the identification and appraisement of light oil layers, residual oilwater layers, high-mud-content reservoirs and gas-water layers. Taking the above as basis and through optimal combination with mud logging data and wireline logging data, an integrated quantitative evaluation method has been summarized for oil-gas-water layer identification. These individual evaluation methods complemented each other. Therefore, the integral application of these methods compensated the deficiencies of single logging technique in oil/ gas layers interpretation and evaluation, effectively solved the knotty problems of reservoir evaluation, improved the accuracy of interpretation and evaluation of oil-gas layer, and presented an obvious effect on the exploration and development of Daqing Oilfield.
