红山嘴油田石炭系火山岩油藏综合研究

COMPREHENSIVE RESEARCH ON CARBONIFEROUS VOLCANIC RESERVOIRS IN HONGSHANZUI OILFIELD

近几年来,随着我国中、新生代含油气盆地中火山岩油气藏的不断发现及各油区勘探程度的进一步提高,构造油气藏、碎屑岩油气藏的勘探开发难度和风险日益增大,火山岩油气藏作为油气勘探的一个新领域,已引起了石油界学者的普遍关注和高度重视[1]。本文以红山嘴油田石炭系火山岩油藏为例,系统总结了火山岩岩性及电性特征、岩性识别及岩相展布特征、储层特征及成岩作用、油气藏特征及成藏机理等方面内容及研究方法。以期为推动我国特种油藏地质学的研究及勘探开发工作的快速发展起到一些借鉴作用,对于推动火山岩油气藏的勘探进程和提高开发效益,丰富石油地质理论,具有重要的意义。

In recent years, the difficulty and risk have increased with the improvement of exploration and development for the structural and siliciclastic hydrocarbon reservoir , and with the continuous discovery of the volcanic hydrocarbon reserves widely distributed in the Mesozoicand Cenozoic basins in China. The volcanic-related rock reservoirs as a new field of hydrocarbon exploration and development has greatly attracted the attention and regard of the geologists in the petroleum enterprises worldwide. Taking a case of Carboniferous igneous rock reservoir in Hongshanzui oilfield as an example, the contents and research methods of lithology and log character, lithological identification and faces distribution, reservoir character and diagenesis, hydrocarbon reservoir character and forming principal are summarized, which can promote the study of special hydrocarbon reservoir geology and speed the exploration and development of special hydrocarbon reservoir. It is significant for promoting the exploration process of development of volcanic hydrocarbon reservoirs and for improving development effect.
