前言我队的工区位于旧州、安次一带,以往曾先后用51型地震仪和模拟磁带地震仪在这里工作过。由于地表多砂,激发条件和埋置条件较差,再加上底部构造复杂,因此多年来中深层构造形态一直未搞清楚。针对这种情况,有必要采用数字地震仪进一步落实这个地区的中深层构造,以便对该区作出正确的油气评价。为了充分发挥数字地震仪的特长,我们把工作重点放在野外方法试验方面。
Preface Our team’s work area is located in the old state, Anzhai area, in the past has used 51 seismograph and analog tape seismograph here worked. Due to the multi-surface sand, excitation conditions and poor embedding conditions, coupled with the bottom of the complex structure, so many years in the deep tectonic shape has not been clear. In response to this situation, it is necessary to use digital seismographs to further implement the mid-deep structure of the area in order to make the right hydrocarbon evaluation in this area. In order to give full play to the strengths of digital seismographs, we focus our work on field method testing.
