Abstract

The invention relates to an oil field steam channeling detecting device which comprises a detector. A wireless signal projector is installed on the detector. The detector is connected with a steam channeling detector through a wire. A solar support and an oil well controller are installed on the detector. A solar collecting plate, a solar converter and a storage battery are installed on the solarsupport. The detector is connected with the oil well controller, the solar converter and the storage battery. The solar collecting plate is a dye-sensitized solar battery. The dye-sensitized solar battery comprises a light anode, an opposite electrode opposite to the light anode, and an electrolyte with which the space between the light anode and the opposite electrode is filled. The light anode comprises an FTO conductive substrate. A TiO2 composite thin film is arranged on the surface of the FTO conductive substrate. A Fe metal net is embedded in the TiO2 composite thin film. The TiO2 composite thin film is formed by silk-screen printing TiO2 composite slurry on the surface of the FTO conductive substrate.

Description

technical field [0001] The invention relates to the field of detection devices in the oil exploitation industry, in particular to a detection device for steam channeling in an oil field. Background technique [0002] Steam channeling occurs during the steam injection process of heavy oil thermal recovery. When steam is injected into one well, the temperature, pressure, water content, and production volume of the surrounding production wells will increase. A blowout phenomenon occurs. With the increase of steam injection huff and puff rounds of heavy oil and the implementation of infill wells in heavy oil blocks, the increase of underground steam injection radius and the reduction of well bottom spacing, the phenomenon of steam channeling is becoming more and more serious. Steam channeling not only seriously restricts the production of heavy oil, but also Moreover, it directly endangers the safety of the oil well production process, and will have a serious impact on the surr...
