【摘要】 地震成藏学是随着地震勘探技术和油气成藏理论的不断发展,为了满足现阶段油气勘探实践需要而提出的一门交叉学科.其主要目的是充分利用先进地震技术解决油气动态成藏问题,促使油气成藏从二维、静态向三维、动态方向发展.本文在石油地震地质学最新研究成果基础上,结合地震研究方法和油气成藏学理论最新动态,通过基本原理、学科特点等的综合分析,重新定义了地震成藏学的概念,厘定了地震成藏学研究思路、核心内容与技术方法体系.认为地震成藏学是在油气成藏理论指导下,充分利用地震信息和先进地震技术对油气成藏的静态地质要素、动态地质过程和油气藏空间分布进行研究,最终实现动态成藏建模的一门科学.认为地震成藏学大致包括四方面研究内容:1)静态成藏要素地震地质研究,2)动态成藏过程地震地质研究,3)油气藏空间分布地震地质综合预测和4)油气成藏地震地质综合评价及建模研究.其中,后三者将成为该学科研究核心和今后攻关主要方向.本文针对地震成藏学的主要研究内容,按照勘探区地质认识程度的不同,分别提出了基于烃源岩地震预测技术、成藏动力地震预测技术、油气输导体系地震预测技术和油气成藏地震演化剖面综合分析等关键技术的地震成藏学解析技术和基于岩石物理模拟、流体置换等地震成藏单元随机模拟技术.更多还原

【Abstract】 Petroleum seismic accumulation is a crossover subject which is to satisfy the require of exploration practice of nowadays in company with development of seismic prospecting and petroleum accumulation academic.Its aim is to solve the problem of petroleum dynamic accumulation with the advanced seismic technique,which urge the study of petroleum accumulation from static state to dynamic state.Based on the new research production of petroleum seismogeology,combined with the new trends of seismic prospecting and petroleum accumulation academic,by the aid of colligate analyzing of the philosophy and peculiarity of this subject,the concept of this subject is redefined,as well as the study content and technique is confirmed.It is considered that petroleum seismic accumulation is a subject that models petroleum dynamic accumulation by studying static geologic feature、dynamic geologic process and spatial distribution of oil pool which using seismic information and advanced seismic technique under the petroleum accumulation theory.This subject includes four study content: static geologic feature、dynamic geologic process 、spatial distribution of oil pool and modeling,which become study keystone and develop way of this subject except the first content.Aiming at the major study content of this subject,according to the disparity of geology cognition of prospecting area,it is put forward that petroleum seismic accumulation resolution technique including source rock seismic prediction technique 、dynamic force seismic prediction technique、petroleum transport system seismic prediction technique and petroleum seismic accumulation evolvement section integrate analyzing and petroleum seismic accumulation element simulation technique based on rock physical analogue and fluid displacement.更多还原
