The pumping unit well mouth polish rod of the present invention seals pouring-in filler and relates to a kind of airtight and watertight padding, is to be become by following components by weight parts numeral system: politef 20～40 parts, aramid fiber 10～35 parts, molybdenum bisuphide 10～35 parts, silicone oil 8～30 parts, tungsten disulfide 5～20 parts, silicone grease 1～10 parts and paraffin 1～10 parts；The present invention is directed to the component of existing airtight and watertight padding and improvement that content is carried out, the purpose improving sealing effectiveness and increasing the service life can be reached, overcome the shortcoming using single lubricant, after aramid fiber, add wearability and involve power, such that it is able to be effectively prevented from crude oil leakage and well head environmental pollution phenomenon, improve the oil extraction operation efficiency of pumping unit.
Description
Technical field
The present invention relates to a kind of airtight and watertight padding, refer more particularly to pumping unit well mouth polish rod and seal pouring-in filler.
Background technology
Along with the development in China oil field, China's major part oil field enters the mechanical oil recovery phase already, and at mechanical oil recovery
Capital equipment used by is sucker rod pumping equipment.According to relevant statistics, China's pumping well with pole constitutes about the 80% of total well number
Above, and wellhead polish rod sealing device is the requisite device of sucker rod pumping equipment, and its performance quality directly affects and lands
Face oil pumper and the work quality of underground equipment thereof and environmental quality, and crude oil can be caused to a certain extent to lose.
And due to fouling, the problem of corrosion, poorly sealed at the wellhead polish rod caused and the Wellhead crue oil leakage that causes
Phenomenon is very universal, causes well head environmental pollution and crude oil loss, and the leakage of Wellhead crue oil result in well mouth of oil well equipment pollution,
Have impact on the further raising of oil field production economy benefit, keep wellhead equipment to clean intact bringing the most also to oil recovery workman
Many troubles, and waste substantial amounts of human and material resources and financial resources.The sealing ring of sealing device is typically used at present: politef
The compactness of fiber can be improved and play lubrication, but the most resistance to temperature, poor radiation；Graphite can improve the tight of fiber
Property, but packing can harden, and is unfavorable for sealing；Molybdenum bisuphide can play lubrication and heatproof, but is difficult to absorption on packing；
Silicone oil can play preferable lubrication.Therefore, in order to ensure sealing effectiveness, need oil recovery workman termly oil well to be patrolled
Depending on and tight packing, considerably increase the labor intensity of oil recovery workman, and add the crash rate of sealing ring, thus reduce oil pumping
The oil extraction operation efficiency of equipment, reduces oil well output.
Summary of the invention
The purpose of the present invention is contemplated to overcome the problems referred to above, it is provided that pumping unit well mouth polish rod seals pouring-in filler.
The pumping unit well mouth polish rod of the present invention seals pouring-in filler, is to be become by following components by weight parts numeral system: poly-four
Fluorothene 20～40 parts, aramid fiber 10～35 parts, molybdenum bisuphide 10～35 parts, silicone oil 8～30 parts, tungsten disulfide 5～20 parts, silicone grease
1～10 part and paraffin 1～10 parts.
As a further improvement on the present invention, described politef 25～35 parts, aramid fiber 15～30 parts, molybdenum bisuphide
18～30 parts, silicone oil 10～25 parts, tungsten disulfide 8～15 parts, silicone grease 2～7 parts and paraffin 2～6 parts.
Methyl-silicone oil selected by above-mentioned silicone oil.
The pumping unit well mouth polish rod of the present invention seals the preparation method of pouring-in filler, realizes through the following steps:
Blended to politef, molybdenum bisuphide, tungsten disulfide, paraffin, silicone oil, aramid fiber and silicone grease heated and stirred is uniform, i.e.
Prepare pumping unit well mouth polish rod and seal pouring-in filler.
As a further improvement on the present invention, described whipping temp controls at 105～195 DEG C, mixing time be 1.5～
15 h。
The pumping unit well mouth polish rod of the present invention seals pouring-in filler, integrates multinomial excellent specific property and efficient function,
Through the flexible gasket that Particular craft and formula produce, there is high intensity, high resilience, softness viscous and super wear-resisting
Excellent specific property.It is added with multiple lubriation material in it, friction with polished rod between can be greatly reduced, and polished rod is had anticorrosion, prevents
Rust function, thus reach to save energy and reduce the cost, the purpose of noise reduction of lightening the burden, also substantially increase the service life of polished rod simultaneously.The present invention
The filler prepared, conveniently can be added flexible gasket by sprue with material feeding instrument under not stopped status
Noting in annular seal space, this fundamentally changes needs frequent shutdown to change packing and the numerous and diverse time-consuming working method of Renewal process.
The effective rate of utilization of flexible gasket can reach 100%, extends the cycle of filling stuffing, filling more notablely
Cycle typically should be truly realized and increased production and improved productivity at about ten months, reduce labor intensity, use manpower and material resources sparingly.
