The invention discloses a preparation method of a sialite binding material for well-cementing in an oil-gas field, which belongs to the field of oil and gas development. The preparation method comprises the steps of mixing (by weight percentage) cement clinker 0-45%, granular blast-furnace cinder 55-95% and pulverized fuel ash 0-5%, and grinding together; mixing (by weight percentage) the ground mixed material 30-59.5%, pulverized fuel ash, coal-fired furnace cinder burnt clay or red mud 40-60% and a diagenetic agent, and grinding together; and mixing (by weight percentage) the ground mixed material 80-95% and ground expanded vermiculite 5-15% to obtain the sialite binding material for well-cementing. The preparation method is not only in favor of solving various problems in well-cementing in the oil-gas field, but also remarkably reduces emission of CO2 and other pollutants compared with that in the conventional oil-well cement production.

The invention discloses a photon energy vehicle energy-saving device and a manufacturing method thereof. The device comprises an air ionizing device and an oil way fine molecularization device. The air ionizing device comprises an outer pipe, side slant wings, a circular air pipe and rhombic air pipes, wherein the number of the side slant wings is plural, the side slant wings are arranged on the outer pipe, the circular air pipe is arranged at the center position of the outer pipe, the rhombic air pipes comprise a plurality of groups, and each group of rhombic air pipes is connected between the circular air pipe and the outer pipe. The oil way fine molecularization device comprises an outer shell, two air guide sleeves, two ceramic bodies and a net structure, wherein the two air guide sleeves are arranged in the outer shell, the two ceramic bodies are respectively connected with the two air guide sleeves, the net structure is arranged between the two ceramic bodies, and connecting bodies are arranged at two ends outside the outer shell. The vehicle energy-saving device has the functions of catalysis fission on petroleum and natural gas, and is capable of achieving ultramicro atomization combustion, improving combustion efficiency, increasing energy, reducing oil consumption or gas consumption, reducing formation of tiny dust, reducing emission of noxious gas such as carbon monoxide and hydrocarbon and achieving energy saving, emission reduction and energy increasing.
