Method for obtaining oil-water common-layer original oil-containing saturation degree and method for estimating non-test oil-water common-layer original oil-containing saturation degree
InactiveCN101413388ABorehole/well accessoriesNuclear radiation detectionCalculation errorPoor correlation
The invention relates to a method for acquiring the initial oil saturation of an oil-water layer and a method for estimating the initial oil saturation of the oil-water layer of untested oil, which relate to a method for calculating the initial oil saturation in a reserve parameter log interpretation. The method solves the problem of large calculation error in the prior method for acquiring the initial oil saturation of the oil-water layer. In the method for acquiring the initial oil saturation of the oil-water layer, the initial oil saturation of a tested oil layer of the oil-water layer is calculated by application of an initial oil saturation model of the oil layer first, and corrected according to interpenetration data and oil testing data to obtain the initial oil saturation of the oil-water layer of tested oil. The method is suitable for the oil-water layer with poor correlation between the initial oil saturation and the resistivity and can be used for calculating the petroleum reserve by the volumetric method. The method for estimating the initial oil saturation of the oil-water layer of the untested oil according to the interpenetration data and the oil testing data is to estimate the initial oil saturation of the oil-water layer of the untested oil by applying and researching the average moisture content of the oil-water layer of a working area.

The device is provided with a first series circuit for receiving the output signal and a second series circuit for receiving the reference signal. The device generates an objective quality signal through a combining circuit which is coupled to the two series circuits. Poor correlation between the objective quality and subjective quality signals, the latter which will be assessed by human observers, can be considerably improved by a differential arrangement present in the combining circuit. This arrangement determines a difference between the two series circuit signals and reduces this difference by a certain value, preferably one that is a function of a series circuit signal. Poor correlation can be improved further by disposing a scaling circuit, between the two series circuits, for scaling at least one series circuit signal. Furthermore, the quality signal can also be scaled as a function of the scaling circuit.
