The central structures of Haita basin was the main area of resources of oil and gas. Tanan depression is also one of the high of the exploration and oil and gas production of the central sructures. With the developing of exploration of Haita basin, Tannan depression ancient buried hill exploration received breakthrough, it opens up very good vista of exploration. Being the most important area of reserves replace, it is necessary to do a reseach for ancient buried hill reservoiring pattern. Through the analysis of ancient buried hill oil sources, reservoir development character and the migration system of oil and gas in Tanan depression, conclusion the main control factor of reservoiring of oil and gas, build ancient buried hill reservoiring pattern in Tanan depression, the very well exploration potential is showed.%中部构造带是海塔盆地油气资源最为富集的地区,塔南凹陷更是中部断陷带中勘探程度最高和油气产量最高的凹陷之一.随着海塔盆地勘探进程的不断深入,塔南凹陷古潜山勘探也获得工业突破,展示出较好的勘探前景.作为重要的储量接替区,有必要对古潜山油气藏成藏模式进行研究.通过对塔南凹陷古潜山油源条件、储层发育特征、油气运移系统的分析,总结出油气成藏的控制因素,建立起塔南凹陷古潜山油气成藏模式,揭示了该区较好勘探潜力.
