Abstract
The utility model provides a simple and practical polytetrafluoroethylene high-temperature resistant coated drill rod with an obvious effect. According to the technical scheme, the drill rod comprises a tubular body (1) and a polytetrafluoroethylene high-temperature resistant coating (2); and the polytetrafluoroethylene high-temperature resistant coating (2) is coated on the inner wall of the tubular body (1), and the thickness of the polytetrafluoroethylene high-temperature resistant coating (2) is more than or equal to 60 microns. The drill rod has good performance of resisting corrosion, scale formation, wax precipitation, abrasion and corrosion of gases such as CO2 and H2S; the service life of the drill rod is prolonged; and the oil production cost is reduced. The production process is environment-friendly, and avoids environmental pollution.
Description
Technical field
The utility model relates to a kind of sucker rod pumping mechanical protection device, especially a kind of fluorine high-temperaure coating drilling rod that gathers.
Background technology
Along with the raising that energy extraction gets into middle and later periods and drilling and production technology, many difficulties are adopted and are adopted well deeply and draw attention day by day, and the requirement to drilling rod in the recovery process is also progressively improving.Drilling rod belongs to the irreplaceable type industry of easy consumption type series products, is the important component part and the wearing detail of oil gas field probing well drill string, and the erosion corrosion of drilling rod will be much larger than mechanical loss to the harm of drilling rod.
Summary of the invention
The purpose of the utility model is to provide a kind of simple and practical, outstanding effect to gather fluorine high-temperaure coating drilling rod, and its technical scheme is: comprise tubular body, gather the fluorine high-temperaure coating; Tubular body inner-wall spraying one strata fluorine high-temperaure coating gathers fluorine high-temperaure coating thickness more than or equal to 60 μ m.The utility model drilling rod external surface sprays the high temperature resistant overcoat of a strata fluorine, and under specified temp, carries out sintering.The utlity model has good anticorrosion, good antiscale property, anti-wax deposition, wear-resistant, anti-CO
2, H
2Gas attack performances such as S in the application life of prolongation drilling rod, reduce cost for oil production.And there is not problem of environment pollution caused in the manufacturing process environmental protection.
Description of drawings
Accompanying drawing is the structural representation of the utility model.
The specific embodiment
As shown in the figure, gather fluorine high-temperaure coating drilling rod and comprise tubular body 1, gather fluorine high-temperaure coating 2; Tubular body 1 inner-wall spraying one strata fluorine high-temperaure coating 2 gathers fluorine high-temperaure coating 2 thickness more than or equal to 60 μ m.
The utility model gathers fluorine high-temperaure coating drilling rod, and gathering the fluorine high-temperature resistant coating is raw material with polytetrafluoroethylene (PTFE) (Teflon) mainly, is equipped with high lubricating auxiliary agent, fully combines through high temperature sintering and drilling rod.Form the certain thickness densification at the drilling rod inwall and gather the fluorine high-temperaure coating, corrosive medium and tubing are isolated fully, prolong drilling life of drill pipe, reduce cost for oil production.In addition, the utility model gathers fluorine high-temperaure coating drilling rod manufacturing process environmentally safe, is a kind of process for cleanly preparing.
Claims (2)
1. one kind is gathered fluorine high-temperaure coating drilling rod, it is characterized in that: comprise tubular body (1), gather fluorine high-temperaure coating (2); Said tubular body (1) inner-wall spraying one strata fluorine high-temperaure coating (2).
2. the fluorine high-temperaure coating drilling rod that gathers according to claim 1 is characterized in that: said fluorine high-temperaure coating (2) thickness that gathers is more than or equal to 60 μ m.
