关于开发地震技术发展的几点思考
|
摘要
开发地震技术是因油气田开发的需要而兴起。随着油气田开发程度的提高 ,开发地震的重要性将更多地显现出来。我国在地震开发技术总体上仍处于发展阶段 ,现有的一些方法 ,或因成像处理及解释手段不够完善 ,或因信噪比、分辨率及精确度不够高 ,只能应用于油气田早期开发。为此 ,提出以下看法。首先 ,地球物理工程师和油藏工程师要转变观念 ,进行相互间的知识和技能的优势互补 ,掌握从地球物理到油藏开发各环节多种技术的综合应用技能 ,形成新的油藏建模技术体系。其次 ,要开展基础研究和实验室模拟研究 ,再进行实际工区的试验工作 ,以促使开发地震技术尽快走向成熟 ;加强方法技术研究 ,例如井间地震资料成像方法 ,井间多波及井中时间延迟地震的资料处理解释技术 ,以及利用井中资料提升三维资料品质等技术难点应尽快突破 ;同时提倡多种技术联合应用 ,使资料有更高的精度和分辨率 ,这样就有利于开发地震技术投入实用
Development seismic arises to meet the need of development of oil and gas field. Its importance becomes more obvious as the increase of development degree. The development seismic techniques are in their seedtime on the whole in China. The existing methods is only applicable in early stage of oil and gas field development because of insufficiency in image and interpretation methods or poorness in S/N, resolution and precision. Based on such observations, the author suggests that firstly, geophysicists and reservoir engineers should give up sense of disciplines, learn from other's strong points to make up each other's deficiencies, and grip integrated skills in using expertise of geophysics and reservoir development to form a new technical frame of reservoir model construction. Secondly, before field tests, fundamental and modeling researches on methodologies such as imaging of crosshole seismic data, processing and interpretation of interwell multi-wave and borehole time-lapse seismic data, as well as quality improvement of 3D data by means of borehole data, should be carried out. To make the developed methods more applicable, emphasis should be laid on integration of different methods.
