摘　　要：大庆长垣南部黑帝庙油层发育于嫩江组第三段、第四段地层中,属松辽盆地上部含油组合。研究认为,本地区的天然气分布主要受构造和沉积控制,断层对天然气的运移起到至关重要的作用,古构造的高点地区(现在处于斜坡带)是现今天然气的有利聚集区;本区沉积相主要为三角洲前缘亚相,砂体厚度相对较小,模糊识别天然气预测显示该油层天然气呈分散状分布;但总体看,由于本区天然气埋藏很浅,容易开发,且天然气预测分布面积之总和具一定规模,因此有较好的发展前景。The Heidimiao oil layer at the southern Changyuan of Daqing develops in the third and fourth section of the Nenjiang Group, and it belongs to the upper oil-bearing assemblage of Songliao Basin. Industrial gas flow has been found at this layer in four wells. According to the researches, the natural gas in this area is mainly controlled by structures and sedimentation, faults play a very important role in the natural gas＇s movement, the high spot areas of paleostructures （in the inclined ramp belts now） are the advantageous gathering places of natural gas today;the sedimentary facies of the area is mainly the delta front subfacies, and the thickness of sand bed is relatively thin, the fuzzy diagnosis of natural gas indicates that the gas of this oil layer is distributed dispersively. But on the whole, there is a good prospect because the superficially buried natural gas can be easily exploited and the total forecasted area is large. Recentely, the authors have obtained 2 wells rich in industrial gas flow in the Heidimiao oil layer through researching.
