中国岩溶型储集体的勘探技术进展及发展趋势

近二十年来,岩溶型储层的勘探取得了长足的进展,主要体现在:(1)传统的地质方法与现代的测试分析及地球化学方法的结合;(2)新的测井技术如电阻率成像测井(FMI)、多极阵列声波测井技术(XMAC)、偶极横波成像测井(DSI)及核磁共振测井(CMR)等的不断涌现并取得了较好的应用效果;(3)以提高地震分辨率和岩溶型储层预测精度为目的的大量新的数据处理、解释技术的出现和改进。比较而言,以钻井、测井研究为基础的地震地球物理方法是当前最有希望取得更大突破的领域。如何改进地震数据的采集和处理,使其成本更低、品质更高和保真性更好,如何更好地将种类繁多的纵向精细而横向稀疏的测井数据和纵向分辨率低而横向密集地震数据结合起来,以及如何培养不仅在岩溶型储层的识别上,还要地质和地球物理知识也坚实的人才或团队等,是整个油气勘探领域急需思考和解决的问题,也是今后油气勘探技术的发展趋势。 

Research review and developmental trends of technology in karst reservoir exploration in China

Exploration of karst reservoir are getting progress in the recent20 years in the following aspects. (1)Combination of conventional geology methods, modern testing technology and geochemistry; (2)Good application effects with new logging technology such as FMI, XMAC, DSI and CMR; (3)A great number of new data processing and data interpretation technology which aim at raising resolution and improving the precision of karst reservoir prediction coming forth and being improved. Compared with other technology and method, geophysics method is the most hopeful area of breakthrough progress. There are still many problems need to be considered and resolved, such as how to improve the technology of seismic data acquisition and processing in order to reduce the cost, how to improve its quality and to increase its fidelity performance, how to comprehensively use logging date and seismic date, how to solve the lack of multidisciplinary talent and workgroup. Those are not only the problems that we must confront but also the developmental trends of technology in petroleum exploration.
