大多数油气藏都是由疏松沉积岩层组成的。因此,对这种沉积物进行室内地震特征研究是很有意义的。为补充以前别人提交的成果,我们对一些由多种晶粒组成的矿物品粒充填岩样进行了测量,这些晶粒是角石英、角奥长石、角板石、圆(?)石和玻璃珠。这就概括了角度和矿物成分这两个方面。利用超声脉冲法取得测量数据,包括加压时的长度压缩校正。扫描电子显微镜观测(SEM)和筛选分析表明:除板石之外的所有材料,其晶粒被压裂和被压碎的有效压力最低也要高达5000磅/英寸~2。对速度数据进行了转换,以求得 Gassmann 模型参数。初步结果表明,骨架的体变模量值与报导的某些天然沉积物的值差不多,并提出,矿物
Most of the reservoirs are composed of unconsolidated sedimentary formations. Therefore, it is significant to study the indoor seismic characteristics of this sediment. To supplement the results previously submitted by others, we measured rock fillings of mineral grains consisting of a variety of grains consisting of hornbled, hornite, angle stone, stone and glass Beads This summarizes both the angle and the mineral composition. The use of ultrasonic pulse measurement data obtained, including the length of compression compression correction. Scanning electron microscopy (SEM) and screening analyzes showed that all materials except for slates had a grain pressure of up to 5000 pounds per square inch (2 pounds) effective to fracture and crush grains. The velocity data is transformed to obtain the Gassmann model parameters. Preliminary results show that the bulk modulus values of the skeleton are about the same as those reported for some natural sediments and suggest that minerals
