摘要
以三维地震为代表的地震勘探经过多年发展已达到相当高的精度水平,但是面对油气藏开发,特别是陆相断陷盆地复合油气藏开发,地震技术仍然面临着巨大的挑战,需要发展油藏综合地球物理技术,主要包括岩石地球物理、特殊地震方法、资料特殊处理方法等。综观目前国际油藏地球物理技术的现状与发展趋势,提出胜利油田的开发地震重点要解决两个问题:①以测井、井间地震等高频资料为约束,实现井地联合反演,最大限度地提高地面地震资料的分辨率。②利用开发地震技术系列,与岩石物理相结合,实现对储集层的定量描述及对储集层内流体的识别。在油藏综合地球物理技术的研究过程中,必须在不同工作阶段始终把握不同技术方法、不同学科之间的最佳匹配与结合,加强以油藏地质为指导、以地震为基础的综合研究。
Seismic exploration with 3D seismic as the main technology has made it a relatively high-resolution technology after many years development. However, the development of oil and gas reservoirs, especially, the kind of fault block reservoir of non-marine facies, which is a worldwide problem, has provide a tremendous challenge for geophysical technology, meaning that the development of comprehensive reservoir geophysics containing petro-physics, special seismic method, special seismic data processing method are needed. The present status and developing trend of reservoir geophysics world widely suggest that two problems related to development seismic should be solved in the Shengli Oilfield, for which one is to improve seismic resolution mostly by constrained inversion of high frequency well logging data and cross-well seismic data, so to realize well to surface combined inversion. The other is to make quantitive description of reservoir and recognition of reservoir fluids by using the series of seismic and its combination with petro-physics. In the research process of reservoir geophysics technology, different technologies and disciplines must be integrated to perform the researches under the guidance of reservoir geology and by taking seismic technology as the basis.
