“非地震物化探”的探索

RESEARCH PROBING OF NONSEISMIC GEOPHYSICAL AND GEOCHEMICAL EXPLORATION

石油物探近30年来均以地震为主,随着科技的发展,单一依靠机械震动的波动场来搞石油物探已暴露出成本高、信息单一的严重缺陷,因此,在应用新一代测量仪器、充分发挥电子计算机作用和综合多种信息的“非地震物化探”技术系列应运而生,并获得了高速度的发展.所谓非地震物化探,实际上就是指应用地质体的重力场、电磁场、化学场等多种物化信息来做石油物探的前期准备和地震勘探的补充.尽管她还处在发展的初级阶段,但已有突破并展示了较好的前景.

In recent 30 years,seismic prospect has been the main means for petroleum geophysical exploration.As the development of scienoe and technology,the serious drawback of highcost and single informationbrought by using only wavefield of mechanical vibration has been exposed in exploration.The nonseismicgeophysical and geochemical exploration technical system(such as the using of series of newborn survey(?)nstruments of eletronic computer and intergrating mueti-information etc.)have generated and are devel-oping with a high speed.Nonseismic geophysical and geochemical exploration technical system means actually the using ofmultiple kind of physical and chemical information from geological bodies,such as gravimetric,electric-magnetic and chemical field ones as a prepared project for petroleum geophysical survey and sup-plement to seismic survey.Although it be only on it's primary stage,some breakthrough has occured and agood prospects is expected.
