Background

Petroleum refers to a mixture of hydrocarbons in gaseous, liquid and solid states, with natural occurrence. Petroleum is classified into crude oil, natural gas liquids, natural coke oils, etc., but "petroleum" is still used as the definition of "crude oil" in a conventional manner. Petroleum is a viscous, dark brown liquid known as "industrial blood". The upper part of the crust has oil storage. The main component is a mixture of various alkanes, cycloalkanes and aromatics. Is one of the main objects of geological exploration. The oil formation mechanism of petroleum has two theories of biological deposition and oil change and petrochemical oil, the former is widely accepted, and the petroleum is formed by the long evolution of organisms in ancient oceans or lakes, belongs to biological deposition and oil change and cannot be regenerated; the latter considers that oil is produced from the carbon in the earth's crust itself, is biologically unrelated and is renewable. Petroleum is used mainly as fuel and gasoline, and also as a raw material for many chemical industry products such as solutions, fertilizers, pesticides, and plastics.

For the production of oil, the hole is drilled by a well-arrangement system planned for the development of the field, the oil rises from the bottom of the well to the passage of the wellhead, and the well is a hole drilled by a drilling method. After drilling oil layer, the oil layer casing is set, and the cement is injected into the annular space between casing and well wall to maintain well wall and seal oil, gas and water layer.

After oil recovery of the oil well, foreign matters such as sand and dust easily enter the oil well to pollute oil, generally, a plug with threads is screwed into an oil well head sleeve, so that the oil well head sleeve can play a certain dustproof and sand-proof effect, but is more troublesome to seal, and the workload of workers during working and working ending every day is greatly increased.
