俄罗斯UMD油田巴什基尔层流体识别方法评价

Fluid Identification in the Bashkirian Layer of Russia's UMD Oilfield

俄罗斯UMD油田巴什基尔层薄层纵向上发育并且有较强的非均质性,属于中孔、中低渗储层。根据不同流体在测井响应上的差别,采用正态分布法、电阻率与孔隙度交会图法、双孔隙度重叠法等方法综合识别该油田油水层。与试油结论对比,其识别结果与生产试油基本一致,可以满足生产需要。

The Bashkirian layer of Russiag UMD Oilfield is thin layers on the vertical development with strong heter- ogeneity, which belongs to the mid - porosity and low permeability reservoirs . According to the different fluid in log response, the article uses the slope degree of the curve in p1/2 ogive, resistivity and porosity crossplot method , dual porosity overlapping comprehensive to identify the oil - water layer. Compared with the conclusions of the test oil , the recognition results and production test oil are basically the same, so the method can meet the needs of pro- duction
