在障碍物密集区进行三维地震勘探,由于城镇、村庄、厂矿企业、铁路遍布测区,障碍物占整个施工面积的50%以上,激发点和接收点布设困难,难以获得地下资料.如何在这样的测区取得高质量地震资料是一个技术难题.需要从设计到施工的全面配合.本文以江苏某区为例说明了在障碍物密集区取得高质量地震资料的设计手段和施工措施.深入讨论了障碍物密集区三维地震施工的方法对策,并概括说明施工方法对后续处理解释的影响和结果.利用这些手段和措施在该区获得了比较满意的地震资料.从而对破解这一难题做出了有益的探索.
Three-dimensional seismic exploration in the densely populated area of obstacles, as the town, village, factories and mines, railways throughout the test area, obstacles account for more than 50% of the entire construction area, the excitation point and receiving point layout difficulties, access to underground information. Of the survey area to obtain high-quality seismic data is a technical problem that requires the full cooperation from design to construction.In this paper, an area in Jiangsu as an example illustrates the acquisition of high-quality seismic data in the obstruction-intensive areas of the design tools and construction measures. The methods and measures of three-dimensional seismic construction in the area with high obstacle are summarized, and the influence and result of the construction method on the explanation of the subsequent processing are summarized, and the satisfactory seismic data are obtained in the area by using these measures and measures. A useful exploration.
