塔里木盆地哈拉哈塘地区具有良好油源地质条件，该地区二叠系火成岩普遍发育，复杂的岩性和剧烈的厚度变化影响下覆油气资源的勘探．为识别该地区英安岩和玄武岩这2种主要分布的火成岩，分析不同岩性的特征响应，选取有效岩性识别参数，进行多参数反演；利用基于D—S证据理论的信息融合技术对多参数反演结果进行融合，挖掘参数反演数据体的优势信息，得到岩性识别的概率体，有效避免传统波阻抗反演结果的局限性．该方法可预测主要火成岩类型在空间上的展布和厚度变化，提高岩性解释精度，在识别火成岩岩性方面取得较好效果．

In this paper,the seismic inversion combined with the well logging,rock physics,seismic facies and the forward modeling was used to comprehensively study the characteristics of the igneous rocks. The rock physics experiment is a useful tool to study the physical property parameters of the igneous rocks. The analysis of the experimental data is helpful to predicting the igneous lithology and velocity. On such a basis,the seismic inversion is used to describe the igneous rocks by the seismic data. The environmental correction and standardization of the original logging curves is the prerequisite for high quality synthetic seismogram and inversion. The constrained sparse spike inversion,the model based inversion and the neural network inversion have higher resolution than the original seismic data. The spatial distribution of igneous rocks can be identified by them,with the model based inversion having the highest resolution. The GR characteristic inversion has higher resolution than the above-mentioned three methods. However,as a single characteristic can hardly be used to describe the characteristics of igneous rocks,the multi-parameter seismic inversion is an efficient way. The seismic facies is also used to obtain the igneous 3D velocity field. The precision of the velocity field is verified by the error analysis and forward modeling.

HLHT area,located in Lunnan low uplift of Tabei uplift,has good conditions for oil source,and recently it's the focused band of Tabei area to exploit oil and gas resource.At present,there have been more than one hundred wells deployed in HLHA area,which commonly encounter igneous rocks.Seriously,the igneous rocks affect the process of oil and gas exploration,which have a big variation in thickness and complex changes in lithology.In this paper,a multi-attribute analysis technology is used for predicting fractures in the area.The results show that the ESP Based on Impedance Inversion,Correlation Window Time Shift to Next CDP and Correlation Length are sensitive attributes to the geological structures in work area,which can show the morphology of configuration clearly.On this basis,the three sensitive attributes are analysized in a superimposed way,which fuses the advantages of each attribute and portrays tectonic structures more clearly.

火成岩的高频屏蔽作用,严重影响到下覆的石炭系和志留系低幅度碎屑岩圈闭以及岩性圈闭的落实,影响了油气勘探进程.利用地震RMS属性技术,对工区内二叠系火成岩在横纵向上的分布规律做了定性研究,研究表明利用RMS属性技术可以检测出不同的地震相带；然后,从地震频率属性上,沿TT和TP层上下进行了火成岩附近不同层位的频率提取,从频率分布图上可以看出火成岩的频率屏蔽作用和频率从浅到深逐渐降低的规律,以及在火成岩的顶底界面出现的频率异常.

民事纠纷作为法律纠纷的一种,一般来说,是因为违反了民事法律规范而引起的,民事纠纷纷繁复杂,纠纷的性质不同、类型不同,解决民事纠纷的方式也应当有别,只有这样才能建立起一套合理的解决不同类型纠纷的体系,以维系社会的稳定.
