| 摘 要： | 在油气勘探与开发过程中,寻求能够从地震资料中直接识别储层油气的流体指示因子至关重要.由于现存多数流体指示因子都是在Biot理论假设前提下建立起来的,因此在双相孔隙介质条件下不能有效地识别流体.为此,本文基于前人提出的双孔介质统一波动理论,考虑岩石裂缝间挤喷流效应,在经典流体指示因子基础上构建了一种新的流体指示因子.该流体因子能够较好地反映岩石内孔隙流体的变化对波传播产生的影响.在实际资料的应用中,采用多种方法分析、对比该流体识别因子与以Biot理论为基础的传统流体因子的优劣,理论分析与实际资料的验证表明该流体因子对于储层中油气的检测有较高的精度和灵敏度.

| Abstract: | In the exploration process of oil and gas, it is important that using a fluid factor to identify gas and oil from seismic data directly. In this work, on the basis of the classical fluid indication factor analysis, we built a new indication factor named as NF fluid factor. Adding the squirt fluid effect between the cracks of rocks, the fluid factor indicates the fluid in the rock pore more possible. It plays a vital role in predicting reservoirs. We compared it with other fluid factors through many methods. We found that it not only indicates the oil but also indicates the dispersion of fractures without the influence of lithology. In oil shale reservoirs, fractures are the main accumulate space, which means that it is the fracture where oil is present. We also compared the production of wells with NF fluid factor time slice and found that the percent of consistence is 85%. In conclusion, the NF fluid factor can indicate the oil from oil shale and ignore the influence of lithology. It is a perfect fluid factor to predict oil in shale. It has been used in real exploration and works well. |
