| 摘 要： | 采集松辽盆地徐家围子地区9口探井57块营城组火山岩石样品,在模拟实际地层温度、压力条件下进行岩石物理参数测试,以期逐步实现火山岩储层流体的地球物理直接识别。采用超声脉冲透射法测定岩样的声学参数(纵波速度和横波速度),进行了不同流体状态下岩样的岩石物理参数特征分析。结果表明,在双参数域空间,特别是在体性-剪性双参数空间,火山岩含气储层与含水储层较易区分。

| Abstract: | To obtain rock physical parameters of 57 core samples from 9 different exploratory wells in the Xujiaweizi area of the Songliao basin, the samples are tested in the laboratory under reservoir conditions. The samples are all volcanic rocks from the Yingcheng Formation. The aim of the experiment is to provide the basis to gradually realize direct fluid identification of volcanic reservoirs by geophysical techniques. With the ultrasonic transmission method, acoustic parameters of the samples have been measured with the velocities of compressional and shear waves. The characteristics of rock physics of the samples in different fluid states were also analyzed in detail. Results indicate that the gas- and brine-bearing volcanic reservoirs can be distinguished in dual-parameter domain space, especially in the space of the body parameter and the shearing parameter. |
