【摘要】 灰岩区是当前地震勘探施工的难点地区。激发因素是地震勘探施工最直接的方法,也是人们进行试验所关注的焦点。虽然前人在灰岩区进行多年多次激发因素试验的选择上取得了一些共识,但仍然没有取得重大突破。在川东北南江地区的地震试验采集施工中,根据多项表层结构调查资料,在一些特定地区进行了有针对性的对比试验,如超大井深试验、超大药量试验、多井组合试验、岩性对比试验、不同封井方式试验、含水性激发试验、不同爆速的炸药类型试验等。在此基础上,提出了在不同条件下对灰岩区需采取的激发因素。更多还原

【Abstract】 Limestone region was difficult to explore now.Shooting factor was the focus that people tested as the directly segment.This study did not get breakthrough in the selection of limestone region shooting factor,although people got some agreement on the basis of many experiment.In the work of seismic data collecting in Nanjina Area North Eastern Sichuan Province,some given contradistinctive experiment was made on the basis of many prospecting data of surface structure,such as ultra-deep-well experiment,explosive quantity experiment,multiwell experiment,lithology comparison experiment,different capping well experiment,aquosity shooting experiment,different detonating velocity experiment,and so on. On the basis of this study,different shooting factors were proposed in different conditions of limestone region.更多还原
