【摘要】 为了研究含盐盆地盐下勘探历史与现状,通过查阅收集大量的资料文献,结合油气地震采集技术,地震资料处理技术与钻探设备和计算机硬件的发展,将含盐盆地油气勘探分为三个阶段:被动勘探阶段(1970年前),主动探索阶段(1970~1990年)和大规模主动勘探阶段(1990年至今),并分析总结了每个阶段的主要油气藏发现与技术设备发展状况。最后,文章从采集技术、成像技术和钻探技术三个技术层面对世界含盐盆地盐下油气勘探前景做出展望。同时也提出我国应了解国外含盐盆地油气勘探现状,学习国外先进的盐下勘探技术,引进相关设备,对我国含盐盆地油气勘探具有重要的指导意义与实践意义。更多还原

【Abstract】 The paper aims to study the history and present state of the presalt oil-gas exploration in the world.Combined with the seismic acquisition technology,drilling technique,seismic data processing technology and the equipment of computer and drilling,the paper collected large amounts of documents and litertures in order to analysis the presalt oil-gas exploration situation which can be divided in to three stages:passive exploration stage(before 1970),active exploration stage(1970~1990)and the large-scale active exploration phase(1990~today).In the each stage,the paper lists the main important discoveries and summarizes the advantage and dis advantage of the development of equipment technology.Finally,the paper makes a prospect view from three aspects,acquisition technology,imaging technology and drilling technology respectively.At the same time,the paper put forward China should understand the situation of the presalt oil-gas exploration of the world,and study the foreign advanced exploration technology and import the equipment.It has the guiding significance and practical significance for the presalt oil-gas exploration in the salt basin of China.更多还原
