DSC mono-conductor multi-function waterflow logging tool consists of pulsed neutron oxygen activation logging tool, neutron lifetime logging tool, natural gamma ray logging tool, casing collar locator and temperature/pressure tool. It can measure parameters such as temperature, pressure, GR, CCL, gamma-ray capture cross section and waterflow in a single logging run.。

Benefits and Features：

- Half-duplex PCM modulation is suitable for either mono-conductor cable or multi-conductor cable.

- A perfect reliability and an easy maintenance with application of computer family, CPLD, DSP and hybrid circuit

- Target voltage stablizing technology of the neutron generator ensures the neutron yield stability and a higher logging precision.

- Neutron sources use a periodic pulse emitting mode to decrease the dissipation of the neutron tube and the neutron generator and ensure their longer operating lifetime.
