摘　　要：纯梁油区油气分布特征分析表明,油气平面上分布于正向构造带,纵向上集中在沙四段、沙三段和沙一段,其石油地质储量占全区探明储量的83.3％,油气富集层位及埋深呈现由北向南、由东往西依次抬高的趋势。该区的构造、油气源、生储配置与盖层、地层不整合等是油气富集的主要控制因素。该研究成果应用于纯化油田外围的滚动勘探,取得了很好的效果。Analysis on oil -gas distribution features in Chunliang petroliferous area show that oil and gas distributed in the positive structure zone in plane, and concentrated in the formations of Es4, Es3 and Es1 in vertical, its OOIP accounts for 83. 3% of the proven reserves in the whole area. The oil -gas enriched horizon and burial depth rise in turn from north to south and from east to west. The structure, oil - gas source, collocation of source-reservoir and caprocks and stratigraphic unconformity etc are the main factors, which control the oil-gas enrichment in this area. The effect of this research is excellent for the rolling exploration in outside area of Chunhua oilfield.
