深层火成岩是当前地球物理、地质和地球化学研究的主要领域之一,因为在该地层中已发现储量可观的油气藏。我们从地震和地质方面对火山岩的特征和分布规律进行了研究,一方面通过火山岩相地震反射特征对储层进行细致的解释;另一方面从钻井揭示的地质因素出发,对火山岩的分布规律进行探讨,并对汪家屯东深层天然气进行了评价。所取得的成果对松辽盆地深层火成岩储层的研究及天然气评价都具有十分重要的意义。

The study of deep-layer igneous rocks is one of the major topics in cur rent geological, geophysical, and geochemical researches, for some hydrocarbon r eservoirs with considerable reserves have been discovered in them. The authors h ave made researches on the characters and distribution pattern of volcanic rocks from the seismic and geologic aspects. On one side, volcanic rock reservoirs we re interpreted in detail according to the seismic reflection characters of volca nic rock facies. On the other side, the distribution pattern of volcanic rocks w ere researched and discussed based on the geologic features revealed by drillin g. And the deep-layer gas in eastern Wangjiatun area was evaluated. All these a re of great significance to the research of deep-layer volcanic rock reservoirs an d the evaluation of natural gas in Songliao Basin.
