一九八二年,西方世界用于地球物理勘探的费用约为四十一亿六千万美元.大约950个陆上地震队和130条物探船,这一年的测线总长度为16亿哩,相当于绕地球64圈.根据我们所了解到的情况,东方集团和中国所投入的地震队伍肯定不少于这个数字.普拉克拉—塞斯莫斯(Prakla-Seismos)公司现有三十五个陆地地震队、六条深海远洋船和近海调查船,此外还有许多重力、大地电磁法和工程地球物理测量队以及航空物探队,进行航磁及闪烁仪放射性测量等工作.这也就是说,我们占据了西方市场的大约3—4%.在世界市场上我们的主要竞争对手是美国的地球物理承包公司,例如:地球资源公司(Geosource)、地球物理服务公司(Geophysical Semice Incorporated)和西方公司(Western)等,此外还有法国的地球物理总公司(GGG).
The cost of geophysical exploration in the western world was about 4.16 billion U.S. dollars in 1982, about 950 onshore seismic teams and 130 exploration vessels, and the total length of the survey line was 1.6 billion Miles, equivalent to 64 laps around the earth.According to what we have learned, the Eastern Group and China are certainly no less than the number of earthquakes in this team.Prakla-Seismos (Prakla-Seismos) company has three Fifteen land-based seismic teams, six deep-sea ocean-going vessels and offshore research vessels, in addition to a number of gravitational, geomagnetic and engineering geophysical measurement teams and aero-geophysical teams for aeromagnetic and scintigraphy radiological measurements. Said that we account for about 3-4% of Western markets and our main competitors in the world market are geophysical contracting companies in the United States such as Geosource, Geophysical Semice Incorporated and Western, etc., in addition to the French Geophysical Corporation (GGG).
