In the east part of China,shallow gas reservoir ususlly produces bright spot reflection in seismic section. Data stacking affects amplitudes, which makes it difficult to use bright spot technique in gas detection. The bright spot due to shallow gas reservoir can be determined by analysing AVO information of P-wave and converted shear wave, instead of conventional stacked section. A method is given of deriving zero-offset longitudinal and converted shear waves from conventional seismic data. A way of making relative...

In the east part of China,shallow gas reservoir ususlly produces bright spot reflection in seismic section. Data stacking affects amplitudes, which makes it difficult to use bright spot technique in gas detection. The bright spot due to shallow gas reservoir can be determined by analysing AVO information of P-wave and converted shear wave, instead of conventional stacked section. A method is given of deriving zero-offset longitudinal and converted shear waves from conventional seismic data. A way of making relative wave impedance inversion is also described. Excellent feasibility of this method is shown by an example of a shallow gas reservoir detection.

Trace integration value represents relative wave impedance.it reflects the variation of relative interval velocity in a seismic section. When absolute interval velocity section can hardly be produced.relative interval velocity section along with drilling, logging.oil field geological informations and so forth can also be used to quantitatively describe thin interbedded reservoir and to model the petrophysical parameters (porosity.permeability and saturation )in three dimensional space. Some trace integration sections produced from the geological models of different complicated thin interbeds are analysed in detail. The characteristics of trace integration section which involves thin interbedded reservoir are detailed systematically. Trace integration characteristic formula independent of wavelet type (zerophase wavelet required)is proposed.offering a theoretical basis for quantitative interpreta tion and numerical modeling. Furthermore, the paper explains how to quantitatively interpret thin interbed thickness in trace integration section, and how to derive three-dimensional data volume of porosity, permeability or saturation,etc. from logging data.

道积分值代表相对波阻抗值,它反映了地震剖面上相对层速度的变化。目前,在绝对层速度剖面很难取准的情况下.用相对层速度剖面结合钻井、测井、油田地质等资料,同样可以对薄互层储层进行定量描述和物性参数(孔隙率、渗透率、饱和度)三维空间的模拟。文中对多种复杂薄互层地质模型产生的道积分剖面进行了研究.系统地描述了薄储集层道积分剖面的特征,并首次提出不依赖于子波类型(要求零相位)的道积分特征公式,为进行定量解释和数值模拟提供了理论依据。另外,本文还提出了道积分剖面薄互层厚度的定量解释方法,以及从井资料出发建立孔隙率、渗透率、饱和度等物性参数三维数据体的方法。

We researched into the sand bodies which are characterized by drag and gravity flow phenomena. We have discovered that the sand units show special geology phenomena (block tearing,block splitting and block migration), and that the sand units retain the characteristics of lithology, petrophysics, water flow and...

Mid interval sand bodies in the third member of Shahejie formation in Fanjia area show complicated geology phenomena,so that explorers have different opinions on sedimentation type of the sand bodies. We researched into the sand bodies which are characterized by drag and gravity flow phenomena. We have discovered that the sand units show special geology phenomena (block tearing,block splitting and block migration), and that the sand units retain the characteristics of lithology, petrophysics, water flow and original structure (oblique bedding) of an original delta front. It is obvious that such a sand unit belongs in a new sedimentation type,namely slump mass sedimentation type. According to the seismic reflection characteristics of sand unit in slump mass sedimentation type,we use the softwares of structural stratigraphy sequence to convert a filtered seismic section into a relative wave impedance section, in which sand bodies can be known by analysing the reflection amplitudes relating to sandrock and mudrock.Quite good effect has been received in the interpretation.

在胜利油田樊家地区,由于s3中的砂岩体呈现出复杂的地质现象,导致勘探家们对这类砂岩体的沉积模式有不同的认识。为此,对该区s3中具有牵引流和重力流双重特征的砂岩体进行了研究,发现这种砂岩体具有块体撕裂、块体裂开和块体漂移的特征,并保存了原三角洲前缘的岩性、物性、水流性质和原生构造(斜层理)等特点。可见,这种砂岩体属于一种新的沉积模式─—块状滑塌沉积模式。根据块状滑塌沉积砂岩体的地震反射波特征,我们利用构造层序软件,将经过滤波的地震剖面转换成相对波阻抗剖面,然后根据砂、泥岩反射扳幅的强弱情况,对砂岩体进行分辨,取得了较好的效果。
