松辽盆地火山岩相:相序、相模式与储层物性的定量关系
|
摘要
松辽盆地火山岩相序主要受岩性控制。酸性岩喷发旋回多以爆发相开始、侵出相结束;中基性岩多以喷溢相开始、火山沉积相结束;酸性岩夹中基性岩的相序复杂,常见喷溢相±爆发相→火山沉积相。风化壳层之上和沉积夹层之上的火山岩是新的喷发旋回的开始,而火山沉积相和侵出相的出现往往标志着一个火山喷发旋回的结束。相模式能够直观反映火山岩相和亚相之间的叠置关系,是地震-岩相解释和储层预测的地质基础。火山岩15亚相中能够成为Ⅰ类储层的通常仅4种:火山颈,热碎屑流,喷溢相上部和侵出相内带亚相。岩相研究使得勘探的目标集中为:火山岩气藏勘探→找有效储层→识别可以作为Ⅰ类储层的4种火山岩亚相发育带。
Facies sequence of volcanic rocks is predominantly controlled by lithotypes in the Songliao Basin. Acidic eruption cycles generally begin with explosive facies and end with extrusive facies. Andesiticbasaltic eruption cycles usually begin with effusive facies and end with volcanogenitic sedimentary facies. Interbeded acidic-intermediate-basic volcanic eruption cycles have complex facies sequence ge- nerally from effusive facies through explosive facies to volcanogenitic sedimentary facies. Weathered crust and sedimentary intercalation are indicative of volcanic intervals. Extrusive and volcanogenitic sedimentary facies are the end-members of an eruption cycle. Facies model described here has been effectively used in seismo-reservoir interpretation in the gas field of volcanic rocks of the Songliao Basin. Only four of the 15 volcanic sub-facies can form high-quality volcanic reservoirs, which include volcanic neck, pyroclastic-bearing lava flow, upper effusive and inner extrusive sub-facies. Well understanding about volcanic facies can make gas exploration easier and more effective: volcanic reservoir exploration → effective reservoir finding → focusing on seismic analytic interpretation of the best four types of volcanic sub-facies which can become potential good reservoirs.
