20161016日至21日,第86届国际勘探地球物理学家(SEG)会议暨展览会在美国得克萨斯州达拉斯市举行。第86 SEG年会的报告形式主要分为三种:口头报告(oral)、电子展板(e-poster)及张贴(poster),另外还专门开展了Workshop和相应的前沿技术培训。会议展厅是全球各大能源公司宣传的主战场,中石油东方地球物理公司、中石化地球物理公司、中海油田服务有限公司和国内多家地球物理企业参加展出并介绍了我国在勘探地球物理技术方面的最新进展。地球科学与技术学院师生在此次大会上宣讲了41个学术报告,其中包括23个大会报告、8个电子展板及10个张贴,针对国内外地球物理勘探形式、地球物理新技术与新方法、岩石物理学前沿以及部分油田勘探实例等方面进行了交流和讨论,展现地学院师生具有较高的学术水平与学术视野,通过保持与国际地球物理学前沿技术的接轨,将促进我校地球物理学科的整体发展水平。

根据自己研究领域重点关注井孔地球物理专题(borehole sessions)共六个,包括中国应用地球物理进展(Progress in Applied Geophysics in China)、井孔声波测量、分析与模拟(Borehole Acoustic Measurements, Analyses and Modeling)、井孔声波与井中地震测量、分析与模拟(Borehole Acoustic and Seismic Measurements, Analyses and Modeling)、井中电阻率测量、分析与模拟(Borehole Resistivity Measurements, Analyses and Modeling)、井中孔隙,偶极辐射和重力测量(Borehole Measurements and Modeling for Porosity, Dipole Radiation and Gravity)、井中测量和模拟(Borehole Measurements and Modeling)。根据关注的专题听取的报告共20场,其中15场为本领域报告,5场为知识拓展报告,分别为LWD unipole for probing azimuthally heterogeneous formation properties: Characterization through numerical modeling and field dataCharacteristics of the collar wave in acoustic logging while drilling (LWD)Well-log lithology discrimination using elastic attributes onlyNew physics-based method to efficiently mitigate noise in borehole sonic logsAdvanced real-time sonic logging data processingReflection imaging away from borehole: A paradigm shiftA new workflow for geomechanical analyses in the Marcellus Shale Gas BasinReliability of velocity measurements of monopole acoustic logging-while-drilling tool in fast formationsWaveform analysis of borehole acoustic dipole data in transversely isotropic medium with a tilted axis of symmetryInvestigation of radiation and reflection on dipole logging-while-drilling remote acoustic reflection surveyWavefield simulation of 3D borehole dipole radiationRadiation characteristics of an acoustic dipole source for single-well imagingA multidetectors pulsed neutron logging technology and its applicationFinite aperture multipole sources, radiation, and impedance loading in fluid-filled boreholesFormation porosity evaluation using nonlinear acoustic second harmonic generationSimulation of monopole seismoelectric logging while drilling using dual sourceDispersion in sonic wave modes caused by global and local flow

此次报告中随钻测井分析、模拟及处理方法报告5场,声波远探测测井分析、模拟及处理方法4场,声波测井时差精细处理方法3场。其他声波数值模拟、电学及核测井方法多场。从报告的数量看,本届SEG年会研究热点为随钻声波测井以及声波远探测技术。随钻声波测井目前已经向偏心单极频域,开始进行了时差准确新的研究主要应用于水平井各向异性地层测量。远探测声波测井进行一些理论研究多采用3D差分和解析方法,同时研究新的偏移成像技术并有多项新进展得到介绍。

通过此次国际会议,认识了本邻域的共同研究人员,结交了朋友,开阔了科研思路,更有利于把握将来研究热点问题。同时也认识到自身英语水平的缺陷,应该积极提高英语交流水平。
