石油地球物理勘探技术的发展及需求

现代物探技术的发展总趋势是主要针对复杂地表、复杂构造、各向异性的地区和开发生产两大领域,以数据库为基础,在卫星及网络支持下,突出以三维数据体为对象的采集、处理、解释一体化,以叠前资料为基础的多域、多属性目标处理解释综合分析,以地震、非地震联合反演为核心的综合地球物理勘探,以地质模型为核心的地震、测井、地震多学科综合研究以及以油藏为目标的勘探开发一体化。当前,我国面临着大面积低丰度岩性、复杂山地山前高陡构造区、高成熟区的小断块、台盆碳酸盐岩、复杂岩性体油气藏等的勘探领域,针对油气藏勘探开发需要的高精度、高分辨率、高保真度的三维地震勘探技术、多波多分量地震技术、3D3C—VSP、随钻VSP、井间地震等井中物探技术以及时间推移地震等技术的研究和应用将更加活跃和潜力巨大。

Development and Demand of Petroleum Geophysical Exploration Technology

The development trend of modern geophysical technology will center complicated surface, complicated structures and complex regions. Based on the data bank and supported by the satellite network, the integration of 3-D data acquisition, processing and interpretation will be highlighted. The exploration and development integration is based on the comprehensive analysis aiming at the processing and interpretation of pre-stack data, multi-regional and multi-property targets and centered on the integrated geophysical technology of seismic and non-seismic inversion and the multi-disciplinary study. Currently, China has a large amount of low-abundance lithologic, complicated mountainous and high-steep structural belts, small high-maturity faulted blocks, platform-basin carbonate rock and complicated lithologic oil and gas reservoirs. With the demand for the high-precision, high-resolution and high-fidelity 3-D exploration technology, multiband and multicomponent seismic technology, 3D3C-VSP and VSP while drilling technology, the seismic technology have greater prospect for study and application.
