塔里木盆地轮南—塔河奥陶系油田发现史的回顾与展望

塔里木盆地轮南和塔河奥陶系潜山风化壳碳酸盐岩油气藏具有相同的油气分布、储层特征、油藏类型和成藏条件,纵横向联成一体,同属于一个大油田。塔里木盆地奥陶系油气藏的发现井是轮南1井,以后经历了艰苦的探索过程,1996年取得了重大突破。从单井高产到获得探明储量,主要依靠一整套先进的地球物理、钻井、测井和测试技术。预计近几年内,轮南一塔河奥陶系油田将向东、西、南3个方向不断扩展,探明储量很快将达到10×10⁸t以上,可采储量达到1×10⁸t。

Review and expectation on the discovery of Ordovician Lunnan-Tahe Oilfield, Tarim Basin

Ordovician buried hill carbonate weathering crust reservoirs in Lunnan and Tahe are identical in oil gas distributions. reservoir characters and types, and accumulation conditions. Being connected together as a whole they jointly constitute a giant oilfield. The discovery of the Ordovician reservoir began with Well Lunnan 1 and after a painstaking exploration a significant breakthrough was made when the Ordovician was explored again in 1996. A series of advanced geophysical, drilling, well logging and measuring techniques had played a key role during the course from achieving a high yield of individual wells to the ascertainment of reserves. It can be predicted that in the following several years Lunnan Tahe Oilfield will continue to expand eastward, westward and southward, its proven reserves will soon exceed 10×10⁸t and the recoverable reserves be up to 1×10⁸t. 
