Wellhead heating device for exploitation of oil and natural gas

Abstract

The invention discloses a wellhead heating device for exploitation of oil and natural gas. A structure of the wellhead heating device for the exploitation of the oil and natural gas comprises a hollowrod, an oil extraction pipe string, a solid rod, a pumping pump, a temperature control device, a terminal device, a four-pass interface, a blow-proof box, a suspension connector, a beam-pumping unit,a connecting cable, a pumping unit bracket, a pumping unit base, a connecting rod device, a motor, a control box, a display and an operation button. According to wellhead heating device for the exploitation of the oil and natural gas, the temperature control device is internally provided with a power failure mechanism, a transmission mechanism, a temperature sensing mechanism, a heating mechanismand an overload protection mechanism, so that the monitoring of heating temperature in the process of heavy oil thermal recovery can be realized; at the same time, the heating mechanism can be openedand closed automatically, the automation degree is high; and the normal production of oil wells can be guaranteed, the waste of resources is avoided, and the economic benefit is high.

Description

technical field [0001] The invention relates to wellhead heating equipment for oil and gas exploitation, which belongs to the field of oil and gas exploitation equipment. Background technique [0002] Since the beginning of this century, the world's crude oil resources have entered the era of heavy oil, and heavy oil will become the focus of the world's crude oil resources due to its abundant reserves. Heavy oil is a high-viscosity, high-density crude oil with poor fluidity, high freezing point, and strong sand-carrying ability. Therefore, heavy oil production is difficult, inefficient, and expensive. 80% of the heavy oil in the world needs thermal recovery. Thermal recovery is an effective measure, or even the most effective only measure, for heavy oil blockage prevention, blockage removal, and high-efficiency recovery. During the thermal recovery process of heavy oil, the viscosity of crude oil is high, Efficient mining requires supporting wellbore viscosity reduction tec...
