Safety protection device for gas production wellhead for special operation and use method thereof

Abstract

The invention discloses a safety protection device for a special operation gas production wellhead and a using method thereof. The safety protection device comprises a head protection mechanism and a face protection mechanism. The head protection mechanism comprises a helmet shell, a top cover, a hoop plate, two connecting frames, a base plate and a storage box, wherein the inner side wall of the helmet shell is in threaded connection with the upper surface of the top cover through screws, the outer side wall of the top cover is welded to the upper surface of the hoop plate, and the two side faces of the helmet shell are welded to the outer side walls of the two connecting frames correspondingly. Through the integrated design, the head protection mechanism and the face protection mechanism can conduct safety protection on the head, the eyes, the ears, the mouth and the nose of a user respectively, and a mask shell in the face protection mechanism can utilize a first filter screen, filter cotton, smoke filter cotton and other mechanisms to form four filter cavities; aiming at filtering different harmful substance aerosol particles in the gas production wellhead, the requirement of comprehensive protection is met.

Description

technical field [0001] The invention relates to the technical field of protection devices for special operations, in particular to a safety protection device for gas production wellheads for special operations and a method for using the same. Background technique [0002] A gas production well is a production well designed according to a gas field development plan (including the use of exploration wells and evaluation wells) or an adjustment plan. It is used to drill natural gas production wells. It is the basic unit of gas reservoir development. Through it, underground natural gas resources are extracted to the ground and become Products, and then turn to commodities and benefits; taking natural gas production wells as an example, its appearance is a hanging casing and oil pipe installed at the wellhead, and a device that seals the annular space between the oil pipe and casing and each layer of casing; according to relevant engineering regulations , During the special opera...

[0002] A gas production well is a production well designed according to a gas field development plan (including the use of exploration wells and evaluation wells) or an adjustment plan. It is used to drill natural gas production wells. It is the basic unit of gas reservoir development. Through it, underground natural gas resources are extracted to the ground and become Products, and then turn to commodities and benefits; taking natural gas production wells as an example, its appearance is a hanging casing and oil pipe installed at the wellhead, and a device that seals the annular space between the oil pipe and casing and each layer of casing; according to relevant engineering regulations , During the special operation of maintenance and repair inside the gas production wellhead, the staff need to wear protective devices such as industrial masks, otherwise the harmful aerosol particles in the wellhead gas will flow into the nasal cavity and mouth of the staff and enter the body; When these protection requirements are met, the standard industrial mask filter element in the traditional technology cannot effectively filter the aerosol particles (such as nitrate aerosol particles, ammonium salt aerosol particles, mica dust, etc.) in the gas well
