我国西北地区侏罗纪煤系地层油气勘探的重大进展丰富、完善了煤成油理论。东北地区中、下侏罗统也是一套煤系地层，同样具有油气生成、运移并聚集成藏的条件，但因早、中侏罗世盆地被多次构造运动破坏，目前多为残留盆地，虽多处发现油气显示，至今勘探未获突破。综合露头、地震、钻井等资料，认为东北地区早、中侏罗世聚煤盆地集中分布在西部沉降带（大兴安岭东缘以西地区，发育７个原沉积区）和东部沉降带（依兰—伊通断裂以东地区，发育２个原沉积区），大致可分为两类：以陆相断陷湖盆沉积体系为特征的陆相盆地，富含煤层，发育有湖相暗色泥岩；与陆间海或大洋有关的近海盆地，部分发育海相—海陆过渡相沉积组合。受勘探程度及资料所限，尚无法恢复９个原沉积区（沉积期间为负地貌单元）确切的早、中侏罗世原型盆地范围，从改造程度和保存条件分析，西部沉降带的二连南部原沉积区（现今二连盆地西南地区）远离大兴安岭火山岩区，被白垩纪盆地覆盖，改造程度最弱，是东北地区开展侏罗系前期勘探的首选地区。 Significant progress has been made in oil and gas exploration of the Jurassic coal measures strata in the northwestern region of China, which has perfected the coal-to-oil theory. Middle and Lower Jurassic in northeastern China is also a coal-bearing strata, which also has the conditions for oil and gas to form, migrate and accumulate into reservoirs. However, since the Early and Middle Jurassic basins were damaged by multiple tectonic movements, most of them are now residual basins Although oil and gas were found in many places, no breakthrough has been made in prospecting so far. According to the data of outcrops, earthquakes and drilling, it is concluded that the early and middle Jurassic coal-bearing basins in northeast China are mainly distributed in the western subsidence zone (west of the east of Daxinganling with 7 original sedimentary zones) and the eastern subsidence zone (Yilan-Yitong fault There are two kinds of original sedimentary areas in the east of China. There are two types of continental basins: continental basins characterized by sedimentary system of continental faulted lacustrine sediments, rich in coal seams and lake-facies dark mudstone; Or ocean-related offshore basins, some of which are marine-continental transitional facies sedimentary assemblages. Due to the degree of exploration and the limitation of data, it is impossible to recover the exact range of the early and middle Jurassic prototype basins in the nine original sedimentary areas (negative geomorphic units during deposition). Based on the analysis of the degree of alteration and the preservation conditions, The original depositional area in the south (now southwest of Erlian Basin) is far away from the Daxinganling volcanic rock area, covered by the Cretaceous basin and the weakest retrofit area. It is the first choice area for exploration in the former Jurassic in the northeast.
