It has been the focused issue, in the geophysical studies, to improve effectively the efficiency of oil and gas exploration, especially the scientific and economic exploration to low abundance oil and gas area. Taking the west slope test area in Songliao Basin which is low abundance oil and gas area as the example, analyzes the characterization precision and differences of different seismic binnings (20 m x20 m, 20 m x40 m,40 m x40 m) on the qualities, faults, structures, reservoir characteristics and so on, and shows the evaluation results of economic exploration and the technical route of evaluation in the low abundance oil and gas area.%提高油气勘探的效益,有效提升油气勘探的性价比,实现科学、经济、有效的油气勘探已成为当今地球物理行业的研究热点与重点,而低丰度油气区科学经济的勘探尤为重要.以西部斜坡区域的试验区块为例,从构造背景出发,分析了低丰度油藏区不同面元(20 m×20 m、20 m×40 m、40 m×40 m)地震数据体的目标层在品质及其对断裂、构造、储层特征等方面的刻画精度与差异,给出了低丰度油藏区经济勘探的成果评价和评价的技术路线.
