松辽盆地徐深气田火山岩气藏地质约束-测井地震建模方法探讨

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...

A research on object-control geology modeling of volcano reservoir with seismic and logging data in Xushen gas field

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.
