中国石油近年来非地震勘探技术应用实例及展望

“十五”以来,随着非地震勘探技术在仪器精度、采集技术、解释软件方面的发展进步,中国石油初步形成针对中国东西部不同地质问题和勘探条件的五大非地震勘探技术系列:复杂地表、复杂地下构造的配套技术、深层(古潜山)构造配套技术、火山岩配套技术、中浅层油气藏检测配套技术和油田开发监测配套技术。介绍了塔西南山前构造勘探、辽河兴隆台低潜山构造勘探、松辽深层火山岩勘探、长庆黄土塬砂体岩性油藏检测、大港房19井区含油气预测和大庆喇嘛甸油田注水方向监测等6个非地震勘探技术的应用实例,分析了非地震勘探技术的应用条件和勘探效果。在综合国内外技术发展动态的基础上,展望三维非地震勘探、直接油气检测、剩余油气动态监测的发展趋势及其应用前景。

PetroChina's Latest Application Examples of Non-Seismic Exploration and Prospects

Since the "tenth Five-Year-Plan ", with the improvement made in instrumental accuracy, acquisition techniques, interpretation software of the non-seismic exploration, PetroChina has preliminarily developed 5 complementary technology series covering about different geologic problems and exploration conditions in the eastern and western China, which include the relevant techniques focusing on complex structures under complicated surface conditions, deep burial hills structure, volcanic rocks, detection of oil-gas reservoirs at shallow-medium depth, and monitoring of oilfield development. Six cases of applying these technologies in exploration for the pediment structure in southwestern Tarim Basin, the burial hills structures exploration in Xinglongtai region of Liaohe Oilfield, deep volcanic rocks exploration in Xujiaweizi depression in Songliao Basin, and oil-testing of sandbody oil reservoir in Heshui loess region in Changqing Oilfield, oil-bearing prediction of Fang 19 well region in Dagang Oilfield, and in Lamadian oil deposits in Daqing Oilfield are introduced, application prerequisites and exploration effects are studied. Based on analyzing the status of techniques at home and abroad, three development trends and their application prospects of non-seismic technologies are forecasted, i.e. 3D non-seismic exploration, non-seismic oil-gas detection, residual oil-gas dynamic monitoring.
