| The Application of Array Induction Logging to Thin Reservoir Identification and Oil-bearing Evaluation: A Case Study of Wensu Uplift in Tarim Basin of Xinjiang |
| Array induction logging has the characteristics of high resolution and deep exploration depth, which can better reflect the features of thin layer resistivity, accurately identify thin reservoirs and precisely judge thin oil layers. The sandstone reservoir of the Neogene Wensu Uplift in the Tarim Basin has good physical properties, the porosity of the oil layer is 22%~28%, and the permeability is 60~210 mD, suggesting the medium high porosity and medium permeability reservoir, density of crude oil is 0.903 8 g/cm3, viscosity is 38.76 mPa·s (50℃), it belongs to conventional thin oil, but its lateral variation is large and the thickness is relatively small. According to the XWD 1 well, 2 well thin sandstone reservoir is difficult to identify, on the basis of reservoir geological characteristics and conventional logging analysis, the authors used high resolution array induction logging to identify thin layers from different vertical resolution resistivity curves, and to analysis sand intrusion characteristics and reservoir permeability, evaluated reservoir oil-bearing property. The high resolution array induction logging technology has greatly improved the accuracy of the identification of thin reservoir in the two wells, effectively evaluated the sandstone reservoir and oil-bearing property in the study area, and guided the work of oil test layer selection, thus achieving good results. |
