摘要
综合介绍和评价了地震资料预测压力的各种方法,认为目前提高地震资料预测压力精度的根本方法是提高速度分析的精度和获得有针对目标区块的经验公式;同时详细分析了获取压力预测速度时需要注意的问题和可能的陷阱;提出利用声波时差等测井资料和实测压力资料获得单井压力模型,并应用单井压力模型指导速度拾取的速度分析方法,该方法基本排除各种非压力因素造成的速度异常.
The current methods predicting the formation pressure are analyzed. The conclusion shows that pressure prediction with the constraints of well is not a good idea. In order to improve the precision of seismic prediction, the precision of velocity analysis must be improved and the empirical formula must be suitable to the researched zone. The pressure concept model is proposed so as to gain high precision velocity. The practice has confirmed that the velocity analysis under the construction of pressure concept model is one of good methods to improve precision of pressure prediction.
