多场信息预测基岩潜山裂缝性油气储层——CB潜山应用实例

Prediction of fractured oil-gas reservoir in basement-buried-hill by using multi-field information: CB buried hill case.

针对海相碳酸盐岩和花岗片麻岩基岩潜山裂缝性油气储层在横向上变化大、非均质性强的特点 ,本文探讨使用构造应力场模拟技术、地震相干分析技术和合成声波测井技术来提取不同场源、从不同侧面反映海相基岩潜山裂缝性油气储层的特征和信息 ,联合对油气储集体做出预测和描述。在勘探生产中应用后证实 ,此方法能够有效地减少对预测目标的多解性 ,显著地减少偏差 ,从而为提高油气勘探开发成功率提供较准确的地质依据。

Aimed at character of severe lateral variation and strong non-homogeneity of fractured oil-gas reservoir in marine carbonate and gravite gneissic basement-buried hill, the paper jointly predicts and describes oil-gas reservoir by trying to use tectonic stress field modeling technique and synthetic analysis technique and synthetic sonic log technique to extract character and information reflecting fractured oil-gas reservoir in marine basement-buried-hill in different sides from different field source. The method has been proved after application in exploration production that it can effectively reduce for predicting target, significantly diminish bias and therefore provide more accurate geologic basis for improvement on rate of success in oil-gas exploration and development.
