【摘要】 论文利用反演技术对火山岩裂缝研究中，无论在方法和应用中都取得了一定的成果。即结合地震资料反演速度的研究，分别使用了多地震属性研究火山岩的裂隙度，以及利用相干体切片、龟裂系数等方法，定性的研究了裂隙度的变化。同时从岩心观察开始结合铸体薄片资料分析、钻井分析、测井分析，通过地震资料测井信息的提取，特别是对测井信息的重构，来达到对火山岩储层和含油气情况的预测，从而形成了一套系统的火山岩研究方法和研究程序。通过这一部分应用方法的研究，论文的结论为，油燕沟火山岩储集层存在时，它的密度降低、速度降低、中子值在一定范围内变化、深浅测向的电阻率幅度差变化也较大、而且当火山岩地层中含油时深浅测向电阻率曲线分开、深测向电阻率值明显增大、浅侧向电阻率曲线值不变的特点，从而给火山岩储层中是否含油气的分析打下了基础。最后研究得到了该目标区中生界火山岩有利储层分布图及火山岩有效厚度分布图。井约束地震压力预测方法的研究，主要是通过井约束反演数据体提取层速度，建立精确速度场，从井出发，应用傅立叶趋势分析求取正常压实趋势层速度，经过衍生Fillippone法计算压力系数场。进一步在压力系数场中分析目的层异常压力分布规律，从而得到目的层段异常压力分布图。由异常压力图与已知井的油水关系出发，结合构造、储层等资料从而得到该区的油气有利分布图。更多还原

【Abstract】 In this paper, It has obtained the breakthrough for crack research technique andthe practice of the volcanic rock, theses research technique and method include studyof seismic attribute, coherent slice of three dimension seismic body, Flexural Strengthetc. Through observation of the core sample, analysis of casting thin slice, loging anddrilling analysis, the author represent a set of system volcanic rock research techniqueand the research procedure, and the research is used to predict oil and gas.The paper has described property of igneous rock and oiliness igneous rock, Itrepresent that igneous rock reservoir has low density, low Sonic speed, there are rangefor neutron value, more higher degree difference of shallow and deep resistivityloging, but deep loging resistivity Increases obviously. For oiliness igneous rock,shallow loging resistivity is no changing and for igneous rock reservoir. Author plotthe reservoir distribution map and effective thickness distribution map of igneous rockof mesozoic for research area.The study of pressure forecast method by seismic and well restraining inversion:the first, having seismic bed velocity, it is established for the precise velocity field bywell restraining inversion data; Using the Fourier trend analysis to take the normalcompaction tendency seismic bed velocity; the second, the pressure coefficient fieldis obtained by deriving Fillippone law; Finally abnormal pressure distributed rulestudy from the pressure coefficient field, Thus obtains abnormal pressure distributionmap of the goal stratigraphic interval, and the distribution map of oil gasadvantageous area by unusual pressure chart and oil/water relationship of typicalwells, and structure, reservoir of study area.更多还原
