花园油田结构构造特征与滚动潜力分析

Structural Characteristics of Huayuan Oilfield and Its Rolling Potential Analysis

通过对花园油田地层精细划分和结构构造重新认识,认为该区经历了极其复杂的构造演化,包括盐隆作用、剥蚀作用、拉张作用、火山作用以及挤压作用。同时对该区块地层结构详细解剖,认为重点层系新下段地层表现为由北向南地层逐步变新,北部存在新下段地层,L33井试油成功,表明油气已经运移到该区块周缘,其周缘的圈闭具有进一步滚动评价潜力。

Based on the fine stratigraphic division and the new understanding of the structure construction of Huayuan Oilfield,it is believed that the area has undergone extremely complex structural evolution,including salt-uplift,denudation,tension,volcanism and compression.At the same time,the detailed analysis of the stratigraphic structure of this block shows that the new lower strata of the key strata are gradually changed from north to south,and there are new lower strata in the north.The successful oil test in L33 Well indicates that oil and gas have migrated to the perimeter of this block,and the surrounding traps have the potential for further rolling evaluation.
