摘要
针对古地貌控制了岩溶储集空间的形成与展布,探索应用古地貌成因组合法恢复塔河油田主体区前石炭纪古岩溶地貌。在岩溶台地、岩溶缓坡地、岩溶陡坡地、岩溶山间盆地等4类二级地貌单元的基础上,增加地貌识别因子,进一步划分出10种三级地貌单元,提高了古地貌形态识别的精度。结合微地貌单元岩溶发育特征和油气储集性能,分析油气产量与地貌的关系,为岩溶储集层预测提供依据。
In view of paleogeomorphology controlling the formation and distribution of karst reservoirs,this paper explored the applicationof paleogeomorphic genesis assembly identification method to restore the pre-Carboniferous paleokarst landform in the major blocks of Ta-he oilfield.Firstly,4 kinds of two-grade geomorphic units（karst platform,karst slope（upper）,karst slope（lower）,karst intermountain basin）are presented,and then landform identification factors are added to further divided the paleokarst landform into 10 kinds of three-grade geo-morphic units,by which the identification precision of paleogeomorphic landform can be improved.Also,combined with the karst develop-ment features and hydrocarbon reservoir properties in micro-geomorphic units,the relationship between petroleum production and geomor-phology is analyzed to provide powerful basis for prediction of karst reservoirs in Tahe oilfield.
