Apply And Research Of Fluid Logging Gas Interpretation In BoZhong Area

Fluid logging system is much more improved in analysis technology than traditional gas chromatograph.The hydrocarbon compounds of traditional gas chromatograph analysis technology includes in C1?C2?C3?iC4?nC4?iCs and nC5,and detected gas components by Fluid logging system are not included the components mention in the above,but extended about nC6?nC7?nC8?C6H6,C7H8?C7H14 and non-hydrocarbon CO2 and H2S etc.For better develop fluid logging system,the key is how to take these extended gas components effectively to serve gas interpretation and explore&develop of oil field.This article is analysis through the 181 reservoirs of 12 wells previous drilled in Bozhong-Area.From the features of fluid logging equipments,combined with features of all gas components parameters,It presents quick identify for oil gas layer with oil gas water index for the full components layers;And presents light components chromatograph model for shallow biodegradation layers.Re-evaluation the 181 reservoir in Bozhong-Aera with the both ways,the coincidence rate is up to 90%with well test,and up to 84.6%with E-logging.This proved that the new methods are feasibility and universality in the Area.
