摘要:

针对长岭1号气田营城组孔隙型和孔隙—裂缝型火山岩气藏,从火山岩岩性分析入手,通过多种方法在对岩性识别的基础上,综合运用测井、地震和随机建模技术,建立了火山岩岩性分布模型,并进一步建立了物性参数三维地质模型,以精细刻画火山岩储层的储集性和含气性。利用成像测井、常规测井和地震分析方法,对裂缝的分布特征进行了分析,为分析火山岩储层的高渗带奠定了基础。在综合构造、岩性、孔隙性、含气性和裂缝性等多种因素影响的情况下,指出了气藏有利分布区块,为气藏的下一步开发指明了方向。

Abstract:

The volcanic reservoir in Yingcheng Formation for Changling-1 gas pool is characterized as pore or pore-fracture types.We used many research ways to identity volcanic lithology,and setup model of volcanic lithology distribution by means of integrating well-logging,3D seismic and stochastic modeling.The 3D geological model of physical property built was used to describe the porosity and show gas in volcanic reservoir.The fractures distribution was determined by FMI well-logging,general well-logging and seismic integration,which contributed to predict the high permeability area in volcanic reservoir.The profitable areas for gas pool were predicted by means of tectonic,lithology,pore,show gas,fissure,etc.which would give a proposal for future exploration of natural gas.

Key words: Volcanic, Changling gas pool, Lithology recognize, Physical property interpretation, Geological modeling, Fracture.
