突泉盆地的侏罗系火山-沉积地层充填序列划分为3个级别的火山-沉积旋回,包括2个一级旋回,5个二级旋回.主要发育于红旗组的暗色泥岩具有一定的生烃潜力,综合评价为中等—好烃源岩,万宝组暗色泥岩生烃潜力较差.上古生界二叠系暗色泥岩具有较大的生烃潜力,是今后进一步加强油气基础调查的工作方向. The Jurassic volcanic-sedimentary stratum filling sequence in the Tuquan Basin is divided into three volcanic-sedimentary cycles, including two first-stage cycles and five second-level cycles.The dark mudstones, mainly developed in the Hongqi Formation, have certain hydrocarbon generation Potential and comprehensive evaluation is medium-good source rocks, and Wanbao Formation dark mudstone has poor hydrocarbon generation potential.The Upper Paleozoic Permian dark mudstone has great potential for hydrocarbon generation, which is the work direction for further strengthening the investigation of oil and gas base in the future.
