Lithology identification method of glutenite reservoirs in Yong-1 block of Dongxin oilfield

As the main type of subtle reservoirs,glutenite reservoir becomes more and more important.However,the lithology identification is difficult because the glutenite is of debris flow and messy accumulation.By taking glutenite reservoirs in Yong-1 block of Dongxin oilfield as example,with integrated application of core,logging,imaging and analytical data,three categories of eleven kinds of rock phase were identified.Through further research on lithology identification methods,the standards for core and logging identification were established by using integrated logging data,and the agreement rate can be higher than 90%.
