裂缝型油气层录井方法探讨

在裂缝型储层中，油气主要充填在裂缝的填隙物中或附着在裂缝表面，在岩屑中显示不明显，选取含油气岩屑样品非常困难，录井识别难度很大，以准噶尔盆地达阪城次凹为例，从岩心录井、岩屑录井、钻井液录井、定量荧光录井以及地化录井等方面进行了分析研究，总结出了裂缝油气储层的录井方法。

Logging Method of Fissure-type Hydrocarbon Reserviors

Hydrocarbon mainly reserves in the fillers of fractures or adheres to the surface of fractures in fractured reservoirs, but is not easily observed in cuttings. So it is very difficult to select cutting samples and identify hydrocarbon for mud-logging geologists. An example from Dabancheng secondary sag, Junggar basin, is taken as an example to do a correlative analysis of methods of mud-logging in fractured reservoirs from core logging, cutting logging, drilling fluid logging, quantitative fluorescence logging and geochemical logging, etc.
