Abstract

The invention relates to an oil field steam channeling detection device. The device comprises a detector. A wireless signal transmitter is installed on the detecting machine, and the detecting machineis connected to the steam detector through a wire. A solar bracket and a well controller are installed on the detector. A solar collector panel, a solar energy converter and a battery are mounted onthe solar bracket, and the detector is connected to the well controller, the solar converter and the battery respectively; the solar energy collecting plate is a dye-sensitized solar cell, and the dye-sensitized solar cell comprises a photoanode, a counter electrode and an electrolyte. The photoanode comprises an FTO substrate, a TiO2 composite film disposed on the surface of the FTO substrate; The TiO2 composite film comprises TiO2 nanoparticles, Fe2O3 / CuO / TiO2 composite nanofibers. Specifically, the Fe2O3 / CuO / TiO2 composite nanofibers and the TiO2 nanoparticles are mixed to prepare composite slurry, and the composite slurry is coated on the surface of the FTO substrate by spin coating.

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...
