Protecting device for water-injection wellhead equipment

Abstract

The invention discloses a protecting device for water-injection wellhead equipment and belongs to the field of oil and gas exploitation. The water-injection wellhead equipment is covered with the protecting device for the water-injection wellhead equipment, and the protecting device for the water-injection wellhead equipment comprises a bottom ring beam, a wall body, a top cover and a crawling ladder. The protecting device for the water-injection wellhead equipment is formed by the bottom ring beam, the wall body, the top cover and the crawling ladder. The water-injection wellhead equipment iscovered with the protecting device for the water-injection wellhead equipment, parts of the water-injection wellhead equipment can be prevented from being stolen by others, and the situation that when wind sand of the outside world is serious, the fine sand enters instruments or valves of the water-injection wellhead equipment, and thus work of the instruments or the valves of the water-injectionwellhead equipment is influenced can be prevented. The wall body and the top cover are each made of a material with the fire-resistance and heat-preservation functions, thus the situation that when the temperature of the outside world is low, the instruments or the valves or the like on the water-injection wellhead equipment are out of order or damaged can be prevented, accordingly, normal operation of an oil and gas well is prevented from being influenced, the economic loss is avoided, and the situation that when the outside world is on fire, the water-injection wellhead equipment is on firecan be avoided.

Description

technical field [0001] The invention relates to the field of oil and gas exploitation, in particular to a protection device for water injection wellhead equipment. Background technique [0002] Water injection is a commonly used reservoir stimulation method in the development of oil and gas fields. It injects water into the oil and gas wells through the water injection wellhead equipment installed at the wellhead of the oil and gas wells to make up for the underground deficit caused by the recovery of crude oil, supplement the energy of the formation, and improve the oil recovery rate and The recovery rate, thereby stabilizing the production capacity of oil and gas wells. [0003] The current water injection wellhead equipment is all exposed at the wellhead of oil and gas wells, and the parts of the water injection wellhead equipment are frequently stolen, and because the external environment is relatively harsh, when the external environment is more sandy, fine sand is easy...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the problem that the water injection wellhead equipment is exposed at the wellhead of the oil and gas well in the prior art, the parts of the water injection wellhead equipment are frequently stolen, and when the external environment is more sandy, fine sand is easy to enter the instrument or valve of the water injection wellhead equipment , affect the work of the instruments and valves of the water injection wellhead equipment, or when the outside temperature is low, the instruments or valves on the water injection wellhead equipment may fail to operate, and when the freezing situation is serious, it may also affect the oil and gas wells. Normal operation will cause huge economic losses, the embodiment of the present invention provides a protection device for water injection wellhead equipment
