【摘要】 随着我国油气勘探程度的不断提高,勘探难度不断加大.全国油气资源战略选区调查与评价项目历经六年,通过对深水海域、西部复杂山地、西藏高原、南方碳酸盐岩、火山岩覆盖区等几类典型地球物理勘探久攻不克的复杂地区开展地震、重磁电、综合地球物理勘探联合攻关,以及天然地震层析成像攻关实验,取得了长足进步,直接带动获得了一批有价值的油气勘探发现和成果,形成了针对深水海域的长电缆地震勘探技术、适用于西部复杂山地和南方碳酸盐岩裸露区的宽线地震勘探技术、高原地震调查技术、复杂地区三维重磁电勘探技术、针对火山岩覆盖区和南方碳酸盐岩裸露区的综合地球物理勘探技术、可应用于复杂山地的天然地震层析成像技术等六项地球物理勘探技术攻关集成.本文介绍了全国油气资源战略选区调查与评价项目所取得的这六项地球物理勘探技术攻关成果.提出了今后在复杂地区开展油气地球物理勘探工作的有关思路.更多还原

【Abstract】 With the increasing effort on hydrocarbon exploration in China,more and more challenges are faced in exploration.The State Project of Strategic Area Survey and Evaluation for Oil and gas Resources has been carried out for 6 years.Under the support of this project, researches on seismic survey,gravity-magnetic-electric survey,and comprehensive geophysical exploration have been performed in several typical geologically complex areas where traditional geophysical exploration methods have been encountering great difficulties for long time.These areas include deep-water seas,western complex mountainous regions,Tibet plateau,carbonate outcrop in the south and volcanic regions.In addition,significant progresses have been made in development of micro-seismic tomography technology.Development of these technologies brings in a large quantity of valuable exploration findings.In total,the following six geophysical exploration technologies have been developed successfully:long-cable seismic profiling exploration technology for deep-water sea,wide-line seismic profiling exploration technology for western complex mountainous area and the areas in south China with carbonate outcrop,plateau seismic survey technology,3D gravity-magnetic-electric survey technology for complex areas, comprehensive geophysical exploration technology for volcanic areas and southern areas with carbonate outcrop,and natural seismic tomography technology for complex mountainous areas. This paper gives a description of these new technologies developed in The State Project of Strategic Area Survey and Evaluation for oil and gas Resources,and puts forward the ideas for geophysical exploration in geologically complex areas in the near future.更多还原
