An evaluation method for relative contributions of heat sources based on helium and application thereof, belonging to the technical field of helium origin identification, migration mechanism, and accumulation process analysis. Relative heat contribution values of the mantle and the crust to a basin geothermal system are estimated by combiningHe/enthalpy ratios calculated according to the formula (1) and the heat balance equation, and an evaluation method for relative contributions of heat sources of helium in the context of deep thermal fluid activities is further improved. A detection device is suitable for deep geothermal resource exploration, thermal fluid activity monitoring in an early stage of oil and gas field development, and geological science research. By precisely evaluating relative contributions of a mantle source and a crust source, combined with temperature and pressure data, a scientific basis is provided for resource development, and exploration risks are reduced.

Evaluation method for relative contributions of heat sources based on helium and application thereof

A system for real-time optimization and adjustment of smart oilfield injection production includes a closed rectangular reservoir simulation box, a reservoir 3D-printed physical model, a simulation production horizontal wellbore system, a simulation injection horizontal wellbore system, a fluid supply system, a fluid collection system, a power fluid system and a computer data collection and control system. The reservoir 3D-printed physical model is in the closed rectangular reservoir simulation box. The simulation production horizontal wellbore system and the simulation injection horizontal wellbore system are in the reservoir 3D-printed physical model. The fluid supply system injects a displacement fluid into the simulation injection horizontal wellbore system in the reservoir 3D-printed physical model to flow to the simulation production horizontal wellbore system. The computer data collection and control system adjusts injection and production volumes of different well sections of the simulation injection horizontal wellbore system and the simulation production horizontal wellbore system.

A single-system air-cooled refrigerator, comprising a refrigerating compartment and a freezing compartment, wherein the refrigerator further comprises: a first air duct and a second air duct, which communicate the refrigerating compartment with the freezing compartment respectively; a first air door and a second air door which open and close the first air duct and the second air duct respectively; a refrigerating system; and a control system, configured to control opening and closing of the first air door and the second air door to implement a first working mode, a second working mode, or a third working mode of the refrigerator. The first working mode is that neither the freezing compartment nor the refrigerating compartment is switched, the second working mode is that the freezing compartment is switched to the refrigerating compartment, and the third working mode is that the refrigerating compartment is switched to the freezing compartment.

Single-system air-cooled refrigerator and control method therefor

Provided are an organic rare-earth solid micelle, a preparation method therefor, and a method for increasing the photoelectric conversion efficiency of a solar battery. A small organic conjugated ligand is taken as a first ligand, an amphiphilic diblock polymer is taken as a second ligand, and the first ligand and the second ligand are mixed and doped with a rare-earth chloride solution, and self-assembled to form an organic rare-earth solid micelle, whereby the fluorescence emission intensity and the fluorescence efficiency of the rare-earth element are improved. Next, the prepared organic rare-earth solid micelle is spin coated on an ITO layer of a solar battery, to prepare a solar battery with the organic rare-earth solid micelle. Therefore the sunlight absorption of a cell is increased, and the photoelectric conversion efficiency is improved. The preparation process is simple, low in cost, high in photoelectric conversion efficiency, and environmentally friendly.
