【摘要】 本文在借鉴徐深气田以往地质建模成功经验基础上,针对徐深气田B区块火山体规模小、横向变化快、开发井少、认识程度较低的实际,密切结合火山岩成因特点,探索性地提出体控地质建模的新思路,即以地震反射特征和地震属性特征为依据,结合钻井、测井资料,井震结合从三维空间上精细识别和刻画火山岩体,通过利用神经网络算法建立多种地震属性与测井参数的定量关系,实现了火山岩体内部多种地质属性的定量表征,建立的三维可视化地质模型比较真实地反映了火山机构及其内部属性空间发育和分布特征.更多还原

【Abstract】 Considering the reality of small volcano scale,few development wells,low knowledge level of block B in Xushen gas field,as well as the volcano origin characteristics,a new idea of body control geology modeling is explored and proposed in this paper on the basis of past successful experience of geology modeling.Based on the characteristics of seismic reflection and seismic attributes and combined with drilling and logging data to accurately identify and describe volcanic body in three-dimensional space,a variety of geological properties of volcanic rock with quantitative characterization is achieved and visual three-dimensional geological model is established which truly reflects the volcanic body and its internal property development and distribution characteristics.更多还原
