注重技术创新,引领技术发展,为油气勘探开发提供强力技术支持——2014 CPS/SEG国际地球物理会议概述

Laying emphasis on technological innovation and guiding the geophysical technique development,to provide the strong geophysical support for hydrocarbon exploration and development——The review of 2014 Beijing CPS/SEG international geophysical reference

2014CPS/SEG国际地球物理会议在北京成功召开,会议发表了关于地震资料采集、处理、解释和其它应用的300余篇学术论文.本次会议整体上注重技术创新和创新技术的应用,会议成果表明,GPU并行计算基本渗透到地震资料处理的各个环节,对于偏移成像来说,该技术使得逆时偏移和全波形反演的工业化大规模应用成为可能;对地震成像技术而言,各向异性TTI介质的声波方程和弹性波方程的逆时偏移仍是地震技术发展的重要方向,提供高精度速度模型和弹性参数的三维波动方程的全波形反演技术是未来十年,乃至更长时间的攻关研究方向.随着勘探的复杂化,非常规油气的地球物理技术和微地震压裂的检测方法正逐渐成为地球物理工作者重视的研究内容;另外,开发和井中地球物理技术是油藏开发后期的剩余油预测、油藏描述和监测的关键技术.

2014 CPS/SEG international geophysical conference was held in Beijing in April,there are about 300 papers on seismic data acquisition,processing and interpretation were published in this conference. The conference is Laying emphasis on seismic technological innovation and the application of the innovated techniques,the results demonstrates that GPU parallel computing almost used in every step of seismic processing,it makes possible that the techniques of prestack reverse time migration and 3D seismic data full waveform inversion used in large scale. For seismic imaging,the anisotropic TTI acoustic and elastic wave equation reverse time migration is still the technological development direction in seismic data processing,the 3D acoustic and elastic full waveform inversion,which can provide the accurate velocity field and other elastic parameters,is the research hot topic in the next decade and even for a longer time.Unconventional oil and gas exploration techniques and the microseismic fracturing detecting approach is becoming the research direction gradually with the increasing of hydrocarbon exploration difficulty,and also,borehole seismic technology is the key technique for residual oil prediction,reservoir description and monitoring.
