世界物探技术现状及中国石油物探技术发展的思考

摘要

As the rapid progress of computer techniques,the development of international geophysical exploration technologies could be summarized to three main trends.Firstly,the channel capacity of land equipments is 150 000 channels,the capacity of marine equipment is 26 cables,and in the future the equipments would develop to million channels.Secondly,acquisition technique would develop towards wide azimuth,high density,wideband vibroseis and dual-geophone cables techniques.Thirdly,processing technique would develop towards pre-stack depth migration,reverse time migration and full waveform inversion techniques.Since the Eleventh Five-year period,PetroChina always adheres to technical development.Keeping a foothold on four major fields,PetroChina continuously organizes geophysical exploration technical research,and obtained great development in the geophysical exploration technologies.However,compared with international major companies,PetroChina still fall far short of independent innovation abilities in equipment manufacturing,computer hardware capability and key geophysical exploration technologies.In view of current situation of international geophysical exploration technologies and based on the practical situation of each exploratory area of PetroChina,the application and future development of PetroChina geophysical exploration technologies are analyzed,and some advices are proposed.%随着计算机技术的快速发展,世界物探技术发展可归结为三大趋势：陆地装备已具备15万道带道能力,海上装备已具备26缆的能力,未来装备向百万道发展;采集技术向宽方位、高密度、宽带可控震源、双检电缆等技术发展;处理技术向叠前深度、逆时偏移,全波形反演等技术发展。＂十一五＂以来,中国石油坚持走技术发展之路,立足四大领域,持续开展技术攻关,物探技术取得了长足的进步。但是,中国石油物探技术与国际大公司相比,在装备制造、计算机硬件能力、关键技术的自主创新能力方面存在较大差距。本文在分析世界物探技术发展趋势的基础上,结合中国石油各探区的勘探现状,就中国石油物探技术应用与未来发展作了分析和思考,并提出了一些可操作性意见与建议,以期推动中国石油物探技术的持续快速发展。
