摘要
火山岩具有结构复杂、岩性岩相变化快、储层非均质性强等特点,从而使火山岩储层的地质建模工作变得十分复杂。在借鉴松辽盆地徐深气田火山岩储层建模技术和经验的基础上,以松辽盆地昌德气田为例,运用建模软件开展了该区的储层建模工作。利用钻井、测井、地震、岩心分析等资料完成了地层分层对比,建立起了昌德气田地层格架,并在此基础上,结合综合地质研究成果,建立了该区的构造模型及属性模型,实现了对目的层段有效厚度的分布预测。其研究成果与后续开发井钻探结果符合性较好,为气藏开发决策提供了依据。
Volcanic rocks are characterized by complex structure,rapid change of lithology and facies,and strong heterogeneity of reservoirs,thus challenging geologic modeling.By drawing on the experiences of the geologic modeling of the volcanic reservoirs in the Xushen gas field,we carried out the geologic modeling of the volcanic reservoirs in the Changde gas field,Songliao Basin.Various data including drilling,logging,seismic data and core analysis were integrated to perform layer division and correlation and to establish the stratigraphic framework of the Changde gas field.These study results,in combination with those of the comprehensive geologic research,were utilized to build structural models and attribute models of the study area.The net thickness distribution of the targets was predicted and the prediction results have been validated by the follow-up development drilling results.These understandings will provide a strong foundation for strategic decision making of gas field development.
