Recently, with the major breakthrough of volcanic reservoir exploration in southern ofsongliao basin, the study of volcanic rocks is more and more taken seriously in the oil and gasexploration. Meanwhile, it put forward a new research topic for region volcanic rockreservoirs. That is formation characteristics and controlling factors of volcanic rock reservoirs.The research key of topic is volcanic rock reservoir. According to existing regional geologicaldata, drilling and logging well data, seismic data, combining with geological-geophysical-geochemical and comprehensive analysis method, we will systematic research volcanic cycleand time in fault depression period. Based on petrology, petrography, reservoir characteristicsof volcanism and their mutual relationship, we will analysis the main controlling factors ofvolcanic rock reservoirs in changling fault depression, provided a scientific basis forexploration and development of volcanic rock reservoir. Specific research as follows:First, establishing volcanic rock assemblage through petrology and petrography ofvolcanic.Second, understanding fracture distribution condition and its relationship with volcanicrocks in the southern of songliao basin, clearing activity cycle and time of volcanic inchangling fault depression.Third, studying characteristics of volcanic rock reservoir and development controllingfactors of volcanic rock reservoir, clearing characteristics of volcanic rock reservoir anddevelopment controlling factors of volcanic rock reservoir. |
