松辽盆地德惠断陷营城组火山机构刻画及储层意义
|
摘要
德惠断陷火山岩储层发育在火山机构以及部分风化壳中,笔者以其火山机构内幕型储层为研究对象,提出综合利用钻井、测井和地震资料对火山机构内幕进行火山机构-喷发单元-岩相逐级精细刻画的方法。通过对岩芯和薄片观察总结了8种火山岩储集空间类型,结合储层物性特征分析火山机构、喷发单元及岩相对火山岩储层的控制作用。研究结果表明:火山岩储层在火山机构中心和近火山口较为发育;喷发单元上部储层优于下部储层,喷发单元中部裂隙较为发育,可形成一套完整的孔隙-裂缝配置;火山岩相中以爆发相热碎屑流亚相、喷溢相上部亚相以及侵出相内带亚相为优质储层。
Volcanic reservoirs in the Dehui fault depression mainly occurred in volcanic edifice and some in weathering zone. The authors take the inside-type volcanic reservoir as a target and use drilling,logging and seismic data to conduct a detailed description of the internal feature of volcanic edifice,volcanic eruption unit and volcanic facies. Eight volcanic reservoir-types are summarized by observations of cores and thin sections,and the influences of volcanic edifice,eruption unit and facies on volcanic reservoir are analyzed in combination with reservoir physical properties. The results show that the volcanic reservoirs are mainly distributed in the center of volcanic edifice or near crater,the reservoir in the upper part of the eruption unit is better than that in the lower part. Cracks are well developed in the central part of the eruption unit,forming a complete set of pore-crack combination. The favorable volcanic facies for good quality reservoirs are eruptive thermal clastic flow,the upper effusive and the inner invade subfacies.
