Abstract
The utility model discloses an isopachous rubber wall stator of a petroleum screw drill tool, which comprises a stator case (1). The inner wall of the stator case (1) is in shape of a linear curve, and is provided with a layer of isopachous abrasive rubber (2). Because the isopachous abrasive rubber is arranged on the inner wall of the stator case, when the rubber stator works and is heated, the swelling capacity is the same, the energy efficiency is greatly improved, and the rubber stator is not easy to wear; the service life of the drill tool is long, which can be improved from the present 150 hours to 300 hours. After the product is put into use, not only a domestic gap in the field is filled, but the problem of long time dependence on imported drill tools of deep well and marine drilling of our country is solved, thereby having important significance for future petroleum exploitation of our country.
Description
Technical field
The utility model belongs to oil-well drilling equipment, relates generally to wall thickness elastomer stators such as a kind of oil helicoid hydraulic motor.
Background technology
The oil helicoid hydraulic motor is widely used in oil drilling, geological drilling operation, but because this kind drill tool life is lower, can only drill 6000 meters with interior oil well, relies on external import drilling tool above 6000 meters for a long time with offshore drilling.
The principal element that influences the present helicoid hydraulic motor life-span be stator rubber do not wait wall thickness, owing to be subjected to the influence of mechanical process capacity, present stator case is the metal circular tube that waits wall thickness, reach final inner hole curve line style, the rubber that hangs up is not wait wall thickness, such stator work adstante febre since rubber do not wait wall thickness rubber layer swell increment different, quick abrasion, efficiency is low, and drill tool life is also low.
Summary of the invention
The purpose of this utility model provides long wall thickness elastomer stators such as oil helicoid hydraulic motor of a kind of not easy to wear, life-span.
The purpose of this utility model can adopt following technical scheme to realize: it comprises stator case, and the inwall of stator case is the line style curve, and the abrasive rubber of one deck uniform thickness is set on line style curve inwall.
The utility model is because the inwall of stator is processed to certain curve line style, and the abrasive rubber of uniform thickness is set on inwall, swell increment was the same when thereby the work of reaching was heated, efficiency improves greatly, and it is not easy to wear, the drilling tool long service life can be brought up to 300 hours by present 150 hours.Not only filled up domestic blank after this product comes into operation, and solved the problem of China's deep-well and the long-term dependence on import drilling tool of drilling at the sea, the oil exploitation of Future in China has been had great significance.
