摘要/Abstract

摘要： 基于Russell提出的流体因子f计算含气饱和度方法可以评价疏松砂岩储层的含气性。偶极横波测井能够准确地测量疏松砂岩的纵、横波速度,与常规测井资料结合可以计算流体因子f。针对疏松砂岩特点提出了调节参数c值的求取方法,该方法能够提高流体因子f对储层流体的评价能力。在柴达木盆地三湖地区应用基于f的含气性评价方法对实际资料进行了处理解释,其结果与生产试气结论具有很好的一致性,说明是一种提高疏松砂岩储层解释精度的有效方法。

Abstract: The method for calculating gas saturation based on fluid factor f which was proposed by Russell could be used for gas-bearing evaluation of unconsolidated sandstone reservoirs. Dipole shear sonic imager (DSI) logging could measure P-wave and S-wave velocity accurately in unconsolidated sandstone, and calculate the fluid factor f, combined with conventional logging data. This paper proposes a method of adjustable parameters for unconsolidated sandstone, which could improve the evaluation capacity of the fluid factor f to reservoir fluid. The result of in situ data processing and interpretation is good in agreement with the gas test results in Sanhu Area of Qaidam Basin, and it shows the method of gas-bearing evaluation based on f could improve the accuracy of interpretation in unconsolidated sandstone reservoi

Key words: fluid factor, unconsolidated sandstone, dipole shear sonic imager logging, P-wave and S-wave, gas-bearing evaluation
