大民屯凹陷低潜山综合勘探技术及效果

大民屯凹陷近年来勘探上连续获得重大突破,先后发现了安福屯、东胜堡西、平安堡等低潜山,成为老油区深化勘探的典范之一,其中勘探思路转变是前提,勘探技术创新发展与应用是关键。针对大民屯低潜山勘探中复杂构造落实、储层识别与评价、裂缝发育及岩性分区预测等关键地质问题,探索并形成了以三维可视化、地震多属性、综合测井评价、储层特征多属性反演等多项技术为核心手段的综合勘探技术系列,并在开展综合评价、指导钻探部署及发现新区带、新领域中起到了关键作用。

Technology and Effect of Integrated Exploration for Burial Hills in Damintun Sag

Several great breakthroughs have been made continuously in Damintun sag in recent years, the discoveries, including Anfutun, western Dongshengpu and Pinganpu burial hills, have been regarded as the typical examples of deepening exploration for mature oil-producing areas. Practical experiences madei n exploration show that changing the idea of exploration is precondition, innovation and development of exploration technique is key factor. Aiming at the key geologic difficulties such as complicated structures, reservoirs recognition and evaluation, fracture developed or not and area prediction of lithology, integratede xploration technique series ,consisting of 3-D visualization, seismic multi-attribute, integrated well logging evaluation, multi- attribute inverse of reservoir characteristics and etc, have been developed , which has played a key role in launching integrated evaluation, guiding drilling distribution and discovering new oil belts and fields.
