摘要

摘要: 根据塔河油田区域地质情况,结合已有的研究成果,对塔河油田碳酸盐岩输导体系进行了深入系统的研究。认为塔河油田碳酸盐岩油气输导体系分为断裂与构造裂隙输导体系、不整合面与风化壳输导体系、奥陶系岩溶孔、缝、洞输导体系。断层及其伴生的构造裂隙和强烈的岩溶作用所形成的岩溶裂缝网络构成了塔河油田主体区的油气输导格架,断层及其伴生的构造裂隙与长期南倾的不整合面构建了塔河油田外围区油气的输导格架。根据油气输导要素特征和输导体系在空间上的配置关系,提出3个有利的油气勘探目标:塔河油田三区北部裂缝—岩溶型油气藏、塔河主体区地层不整合—岩溶型油气藏和塔河油田南部盐下奥陶系岩溶—裂缝型油气藏。

Abstract: The hydrocarbon carrier system of carbonate rock in the Tahe Oil Field has been studied systematically according to regional geologic condition.The above-mentioned carrier system can be divided into three types: 1)fault structural fissure;2)unconformity and paleo-weathering crust;3)Ordovician karst pore,fracture and vug.Fault and its concomitant structural fissure as well as karst fracture network resulted from severe karstification effect work as hydrocarbon carrier system in the central Tarim Oil Field.Fault and its concomitant structural fissure as well as unconformity dipping to the south chronically work as hydrocarbon carrier system in the peripheral region of the oil field.According to the features of hydrocarbon carrier elements and their spatial arrangement,three favorable exploration targets have been pointed out: 1)fracture-karst type reserves in the north of block no.3 of the Tahe Oil Field;2)stratigraphic unconformity-karst type reserves in the central Tahe Oil Field;3)lower Ordovician karst-fracture type reservoirs in the southern Tahe Oil Field.
