| 摘 要： | 辽河坳陷第三纪火山岩喷发造成了较高地温异常，使部分烃源岩早熟，提供油源；火山岩原生和次生孔隙使其可成为储集层，在一定条件下可成为盖层。这使辽河坳陷存在多种与火山岩有关的油气藏。火山岩发育区可以形成有经济价值的油气藏，是该类地区油气资源评价中值得重视的问题。

| Abstract: | The early maturation of source rocks due to the higher geothermal field created by the Tertiary volcanic explosion in Liaohe rift basin provided the hydrocarbon sources. The primary and secondary pores of volcanic rocks provided reservoir space there. Volcanic rock may become cap rock under certain conditions. Thus, this organic combination of many favourable factors formed many types of oil-gas pool associated with volcanic rocks in Liaohe rift basin. Volcanic activity in volcanic rock area can form economic and commercial oil and gas pools under certain conditions, which is a issue to be brought to attention in hydrocarbon resource evaluation for volcanic rock regions. |
