Problems solved by technology

[0004] The object of the present invention is to provide a heating and oil-water-sand separation device for oil storage tanks in oil fields, which solves the problem that crude oil cannot be transported due to the condensation of crude oil in the existing oil storage tanks at extremely low temperatures in winter, and at the same time can use Low-temperature heating discharges the water and sand contained in the crude oil, and the invention uses the simplest water as the heat conduction carrier, which also greatly reduces the cost

Abstract

The invention relates to an oil storage tank heating and oil-water-sand separating device for oil field, which can be used for non-continuously heating a field oil storage tank in winter and for accelerating separation of water and sand from oil and automatically discharging water and sand to the outside of the tank by heating. The device comprises a master controller, a heating apparatus, an oil storage tank and a buffer tank. A heat exchanger in the invention adopts a single-pipe double-layer design. As a result, the inventive device solves the problem of an existing oil storage tank that crude oil fails for transportation due to condensation of the crude oil in the tank at an extremely low temperature in winter, discharges water and sand from the crude oil by low temperature heating at the same time, adopts simple water as heat conducting carrier, and greatly lowers costs.

Description

technical field [0001] The invention relates to a heating device for an oil storage tank in an oil field, in particular to a heating device for an outdoor oil storage tank in winter and for separating oil, water and sand. Background technique [0002] At present, for oil wells under cold conditions in the field, due to the low ambient temperature, crude oil will solidify after being extracted and stored in oil storage tanks, and cannot be transported, resulting in production shutdown in winter. Existing heating devices are directly heated by electricity, and are also heated by thermal fluid as a carrier. Due to direct heating with electricity, there will be short-term high temperature and electric sparks, which are very dangerous to the oil field. And use thermal fluid as carrier heating, because this kind of heater is often only used in winter, and will not be used in other seasons, thermal fluid will condense at high temperature, often can only be used for one season, and...
