为了提高石油地震勘探野外工作的效率,从七三年来,我们便着手研制地震勘探载波传输仪。多年来,我们与四川石油管理局地调处协作,经过反复实践,先后试制了DZZ—1,2,3,4四种机型的地震勘探载波传输仪。前两种有自控系统,后两种具有线性传输特点。改进后的4型机具有低噪声和成套设备,可以用于野外生产。这种地震勘探载波传输仪(简称地震载波仪),只用两根轻便导线,使用方便,且能改善野外地震记录质量,有利于提高生产效率。 DZZ—4型地震载波仪(见图1)制成后,进行了一系列的室内指标测试。于七七年十一月下旬至十二月上旬在四川省潼南县某构造上
In order to improve the efficiency of the field work of oil seismic exploration, we started to develop the seismic survey carrier transmission instrument in the past seven or three years. Over the years, we and the Sichuan Petroleum Administration in coordination with the Department, after repeated practice, has trial-produced DZZ-1,2,3,4 four models of seismic exploration carrier transmitter. The first two have automatic control system, the latter two have linear transmission characteristics. The improved Type 4 machine features low noise and complete equipment for field production. This seismic survey carrier transmission instrument (referred to as the seismic carrier), only two light conductors, easy to use, and can improve the quality of field seismic records, help to improve production efficiency. DZZ-4 type of seismic carrier (see Figure 1) made after a series of indoor index test. In late November, 1977 to early December, a construction in Tongnan County, Sichuan Province
