平湖油气田扩建中的储层预测

储层预测是平湖油气田扩建中储量确定的核心问题。但该区岩性与波阻抗相关性不好，现有技术条件下，无论何种储层预测方法都存在多解性和不确定性。为此，综合应用重构声波伪岩性反演、高分辨率波阻抗反演、综合地震属性分析、叠后一次导数处理后特征追踪等多种方法对储层进行预测，对预测分布结果进行相互验证，多种方法预测都证明其预测范围的一致性，预测的结果可靠性较高，从而降低了勘探开发的风险，为平湖油气田扩建打下了基础。同时，预测的结果得到钻探的证实。

Reservoir Prediction in the Expansion of Pinghu Oil and Gas Field

Reservoir prediction is the key problem of reserves determination in the expansion of Pinghu Oil and Gas Field. In consideration of the characteristics of poor correlations of lithology and wave impedance in the area, under the available technical conditions, there exist multi-solutions and uncertainty in any methods. Therefore the methods for false lithological inversion of reconstructing sonic wave, high resolution impedance inversion, comprehensive seismic attribute analysis and the characteristic tracing after the first derivation process are comprehensively used to predict the reservoirs. The predicting results are proven each other, it is demonstrated that the methods used for prediction are consistant within the range of prediction, the results are highly reliable, by which exploration risks are reduced, a base is laid down for the expansion of Pinghu Oil and Gas Field, at the same time the results are proven in well drilling and exploration.
