大庆油田裸眼井测井技术进展与展望

Progress and prospects of open-hole well logging technology in Daqing Oilfield

为了提高大庆油田裸眼井测井技术支撑能力和研究成果领先水平,全面回顾了大庆油田测井采集系列及解释技术的创新发展历程,系统总结了特高含水期剩余油解释、火山岩等复杂岩性测井评价、碎屑岩储量参数解释、非常规油气“甜点”分类、缝洞型碳酸盐岩储层测井评价等油田勘探开发测井评价技术。在客观分析大庆油田勘探开发测井解释评价需求和面临瓶颈问题的基础上,结合当前油田测井评价对象规模小、物性差、埋藏深、地层结构复杂、非均质性强的特点。指明了测井解释评价核心技术主攻方向。围绕新阶段测井采集及解释评价技术体系完善与建立,对高分辨率和成像测井采集、后油藏时期和非常规测井解释评价、新一代智能解释技术体系等未来发展进行了展望。

In order to improve supporting capability and research advance level of open-hole well logging technology of Daqing Oilfield,innovative development process of logging acquisition series and interpretation technology in Daqing Oilfield are comprehensively reviewed.Logging evaluation techniques for oilfield exploration and development are systematically summarized,including interpretation of remaining oil in ultra-high water cut stage,logging evaluation of volcanic rock with complex lithology,interpretation of clastic rock reserves parameters,classification of unconventional oil and gas“sweet spots”and logging evaluation of fractured-vuggy carbonate reservoirs.The main direction of core technology for logging interpretation and evaluation is proposed on the basis of objective analysis of logging interpretation and evaluation requirements and bottleneck problems of Daqing Oilfield exploration and development,and combined with current characteristics of logging evaluation targets of the oilfield including small scale,poor property,large burial depth,complex strata structure and high heterogeneity.Future techniques development are prospected,including high-resolution and imaging logging acquisition,unconventional logging interpretation and evaluation in late development stage of reservoirs and new generation of intelligent interpretation technology system,focusing on improvement and establishment of logging acquisition and interpretation evaluation technology system in new era.
