【摘要】 华北油田富油凹陷已有几十年的勘探历史,其中规模大、埋藏浅、构造简单的圈闭多己被发现且钻探;对于形态好、面积大、成藏条件较好的构造圈闭将越来越难以发现。该油田的现状为资源转换率低,但其剩余资源仍很丰富,为此需要加大对现有油田的勘探力度。随着油气地球物理勘探技术的发展,尤其是三维地震勘探的发展,对老区重新进行三维高精度地震勘探工作,实现对老区挖潜,使之成为增加石油储量的主要途径。饶阳凹陷是冀中探区油气最富集、勘探潜力最大的富油凹陷之一,其勘探面积约5280 km~2。其中,蠡县斜坡是饶阳单斜凹陷的组成部分,是其非常重要的勘探区域,属一个北东向继承性的大型西斜坡,其勘探面积约2000km~2,约占饶阳凹陷的三分之一,具有良好的扩大油气产量前景。随着三维地震技术水平的不断提高,单一三维地震资料的构造信息解释,向着以三维地震资料为主体、综合利用该区内已有测井、录井等勘查资料,提供储油构造信息、岩性特征,又进行含油气层预测的全信息解释。挖掘所有可利用资料的信息应用于油气勘探开发之中,已成为当前三维地震解释研究的热点之一。本论文以饶阳凹陷蠡县斜坡三维地震资料为主,结合测井、录井等资料,开展三维地震立体解释,利用相干体和地震属性提取,波阻抗反演,分频解释等先进技术,研究以下主要内容:①探索适用于华北油田饶阳凹陷蠡县斜坡储油气地质特征的所谓三维地震资料全信息解释方法;②以三维地震为主,对蠡县斜坡建立全信息地球物理模型,它包括:构造—地球物理型、岩性—地球物理模型、地层—地球物理模型及油气藏地球物理模型:③对蠡县斜坡雁翎东南翼地区,应用所建立的地球物理模型进行全信息解释。本论文主要研究成果有:①首次对饶阳单斜凹陷蠡县斜坡三维地震资料开展三维地震资料全信息解释,并建立了该区全信息地球物理模型,对华北油田扩大储量、预测油气提供一套切实可行的技术方案;②应用所建立的地球物理模型对蠡县斜坡雁翎东南翼地区进行全信息解释,圈定出新的隐蔽油气藏。更多还原

【Abstract】 The oil-rich sag of north China oil field has several decades exploration history, in which the traps of large scale, shallow burial depth, simple structure have been found and drilled; the structural traps of good form, large area, good accumulation condition are more and more difficult to find. The status of this oil field is low of resource conversion rate, but the residual resources are still abundant, therefore, it’s needed to increase exploration. With the hydrocarbon geophysical exploration technology development, especially the development of 3-d seismic exploration, the main way of the increasing of oil reserves is anew developing high precisim 3-d seismic to old oil field and realization potential tapping to old oil field. Raoyang sag is one of oil-rich sag in central Heibei area, which has rich oil and huge exploration potential, and it’s exploration area is about 5280 km~2 . Lixian slope is a part of Raoyang sag and it’s very important exploration area. It is ne-trending and successive slope, the exploration area is about 2000 km~2, accouting for one third of Raoyang sag. It has good prospect for enlarging oil and gsa output.With the increase of 3-d seismic technology, the single structural interpretation of 3d seismic data has transformed to mainly based on 3d seismic data, comprehensively utilized existing logging, mud logging and others exploration data to provied oil-bearing structure information, lithologic features and predict oil and gas bearing serics. Mininging all of available data to apply in petroleum exploration and development has become one of the hotspots in the research.This paper carries out 3-d seismic cubic interpretation and use coherence cube, seismic attribute extraction, impendance inversion, frequency division interpretaion of such advanced technology, based on mainly the 3-d seismic data of Raoyang sag , Lixian slope and combined with logging, mud logging data and so on. Study the following main content:①explore the full information interpretation method of 3-d siesmic data that is suitable for oil and gas bearing geological characteristics in Lixian slope, Raoyang sag, north China oil field.②Based on mainly 3-d seismic, we establish the full information geophysical model for Lixian slope, it includes: structure- geophysical model, lithology- geophysical model, formation- geophysical model and reservoir- geophysical model. In this paper, the main research results are:①It’s the first time to carry out full information interpretation of 3d seismic data in Lixian slope, Raoyang sag, provide a feasible technical scheme to expand reserves and propect oil and gas in north China oil field.②We use the established geophysical model to carry out the full information interpretation in the southeast wing of Yanling, Lixian slope and delineate new subtle reservoir.更多还原
