COMMAND 组:用电阻率制作合成记录,《石油地球物理勘探》,23(4)1988:504～512问题的提出在制作合成记录时,通常都要用到声波测井资料。如果某些井段缺少声波测井资料,那么所作的合成记录就不能反映所缺井段的速度变化情况及与反射波之间的关系。图1是用巴楚地区和深二井的声波测井资料在 COMMAND 机上作的合成记录。由于声波速度和地震波速度的不同,根据声波速度换算的钻井岩性柱状剖面和自然电位及电阻率曲线图,在井深957m 和2052～2679m 井段附近,可以看到地层的岩性和电测井
COMMAND GROUP: Making Composite Records with Resistivity, Petroleum Geophysical Prospecting, 23 (4) 1988: 504-512. PROBLEM PROBLEMS Sonic log data are commonly used in composite recording. If some well sections lack sonic logging data, the synthetic records can not reflect the changes in the speed of the missing wells and their relationship with the reflected waves. Figure 1 is a composite record of the acoustic logging data from the Bachu area and Shen’er well on COMMAND aircraft. Due to the differences in acoustic velocity and seismic velocity, lithology and electrical logging of the formation can be seen near well intervals 957m and 2052 ~ 2679m according to acoustic lithography converted lithological columnar cross sections and natural potential and resistivity curves
