厄瓜多尔Oriente盆地T区块勘探开发研究表明,白垩系地层平缓、构造简单,圈闭类型主要为低幅度构造圈闭、岩性圈闭及岩性-构造复合圈闭等隐蔽型圈闭。结合T区块油气勘探实践经验,分析总结其北部地区隐蔽型圈闭识别难点,提出了以精细对比建立等时地层格架为基础,地震属性提取技术、频谱分解技术以及测井地震联合反演技术等储层预测手段为核心的隐蔽圈闭识别技术研究思路,进而开展研究区的隐蔽圈闭识别工作,提高勘探成功率。
The exploration and development of Block T in the Oriente Basin in Ecuador show that the Cretaceous strata are gentle and simple in structure. The trap types are mainly low-amplitude structural traps, lithologic traps and lithologic-structural composite traps. Combined with the practical experience of T block exploration, the difficulties of hidden trap identification in the northern area are analyzed and summarized. Based on the fine contrast of isochronal stratigraphic framework, the seismic attribute extraction, spectral decomposition and log-seismic joint inversion Technology and other reservoir prediction methods as the core of the hidden trap recognition technology research ideas, and then to carry out the study area of the hidden trap identification work to improve the success rate of exploration.
