四川探区1992年度地震勘探成果钻探检验已于近日揭晓,77口检验井有62口符合,符合率约81％,较上年提高7.1％,与包括1992年在内的前5年平均水平相比,提高8.9％。在四川盆地这类复杂多变的区域内进行地震勘探,提高勘探精度的难度很大。近年,主要担负上述工作的四川石油管理局地质调查处,努力发挥现代数字地震技术的优势,从施工设计、施工过程、资料处理解释等不同环节层层把关,提高质量。每年施工作业数万炮次,合格率均在99.5％以上;专业技术人员对高质量的第一
Sichuan exploration area 1992 annual results of the seismic exploration drilling test has been recently announced, 77 inspection wells were 62, with a rate of about 81%, an increase of 7.1% over the previous year, including 1992, including the first five years of the average level Than the increase of 8.9%. It is very difficult to conduct the seismic exploration within the complicated and ever-changing region of Sichuan Basin to improve the exploration accuracy. In recent years, the Geological Survey Office of Sichuan Petroleum Administration, which mainly undertakes the aforesaid work, has made great efforts to exert the advantages of modern digital seismic technology and has improved the quality at different levels from construction design, construction process and data processing and explanation. Thousands of construction operations each year, the gun pass rate of 99.5% or more; professional and technical personnel of high-quality first
