While those of the Carboniferous are rhyolite-dacite-andesite formation of transitional-continental environment with crustal compositions.
石炭系火山岩主要是流纹岩-英安岩-安山岩建造，它们产出于海陆过渡相-陆相环境，属于地壳成分。So the research findings will provide reliable evidence for the palaeokarst reservoirs evaluation and favorable area optimization.
上述研究成果将为川东石炭系古岩溶型储层评价与有利区带优选提供可靠依据。Songliao Basin ; Carboniferous-Permian ; Prototype basin ; Basin simulation ; Thermal history; Hydrocarbon-generating history.
松辽盆地；石炭-二叠系；原型盆地；盆地模拟；热演化史；生烃史。The aperture constitute the main reservoirs of Carboniferous space provided for the oil and gas reservoir sites.
这些孔缝构成了石炭系的主要储集空间，为油气的储集提供场所。The formation of relatively simple, mainly of Cambrian, Devonian Carboniferous series leaf pond formation, Cretaceous strata.
地层较为简单，主要有寒武系—泥盆石炭系地层、白垩系上统叶塘组地层。two of three group's acidic volcanic rock's elements in Carboniferous were in tension stress, the one was in extensive environment.
石炭系的三组酸性火山岩成分中有两组处于挤压应力状态，一组处于应力拉张状态。The dissolution convection may be an important mechanism for the migration and ccumulationof gas pools.
水溶对流可能是石炭系天然气运聚成藏的重要机制。The stratigraphy is shown as volcanic formations of Devonian and volcanic-sedimentary formations of Lower Carboniferous.
矿田地层为泥盆系火山岩建造及下石炭统火山-沉积岩建造。The basin has multiple reservoir-seal combination, reservoir bed distributed in the formations from Carboniferous to Tertiary.
