Abstract: Through analysis on an effective detection space of a gamma detector, a one-dimensional equivalent longitudinal contribution coefficient (varying with a distance between a formation and the detector) of a natural gamma-ray flux received by the gamma detector under the condition that the formation and a wellbore are orthogonal is obtained in the effective detection space, and then a corresponding function expression is given by fitting. An integral of a gamma-ray flux received by the detector under the condition of a deviated well is converted into a one-dimensional equivalent integral problem under the condition of a straight well, so as to achieve the fast forward of natural gamma-ray logging of the formation under the conditions of highly-deviated and horizontal wells. This simplified fast forward algorithm can replace a gamma forward method of spherical spatial-division integrals in parallel sedimentary formations, reduce a space-time complexity of algorithms, and improve a calculation efficiency.

The phototransistor apparatus can include a phototransistor, a light source, and a supply voltage associated with the phototransistor. After switching on the supply voltage, the phototransistor can generate a phototransistor signal that is scanned, wherein the supply voltage associated with the phototransistor is switched on later than the light source, and wherein charge carriers in a base area of the phototransistor are reactive to a light pulse from the light source in a currentless state, and continue to react after the light source is switched off. Alternatively, the power supply of the phototransistor can be switched on before the light source is switched off. By delaying the switching on of the power supply of the phototransistor compared to the switching on of the light source, a significant current saving can be achieved.
