Abstract
A combined drill stem with a long service life has the technical scheme that: the drill stem comprises a whole drill stem, the upper end of the whole drill stem is connected with an internal threaded conversion connector in a threaded way, the lower end of the whole drill stem is connected with an external threaded conversion connector in a threaded way, and an overlaying wear-resisting belt is arranged on the outer wall of the internal threaded conversion connector. Compared with the prior art, the drill stem has the advantages that the drill stem has simple structure, low cost and long service life, is easy to change, has high recycle rate and is convenient to connect, to operate and to widely apply in an oil/natural gas well drilling and a non-excavating field.
Description
One, technical field
The utility model relates to the drilling rod that a kind of oil, gas drilling and non-excavation use, and is a kind of high life sectional rod concretely.
Two, background technology
At present, in oil, gas drilling and non-excavating construction process, drilling rod is the drilling tool that generally uses, and also is topmost cost input, and the height of drilling life of drill pipe directly influences the construction economy benefit.The average life of common drilling rod, after often drilling rod was scrapped, under existing technical conditions, body and joint all can't continue to use about 3 years.But the body of scrapping drilling rod still has higher repeat value with regard to its functional performance.If integral body is scrapped, very easily cause the huge waste of resource.
Three, utility model content
The purpose of this utility model is exactly the defective that exists at prior art, and a kind of simple in structure, high life sectional rod that recycling rate of waterused is high is provided.
Its technical scheme is: it comprises stem, the stem upper end internal thread crossover sub that is threaded, and the stem lower end external screw thread crossover sub that is threaded, internal thread crossover sub outer wall is provided with the build-up wear-resistant band.
The utility model has advantage simple in structure, easy to connect, with low cost, long service life, and is easy to replacing, simple operation, recycling rate of waterused height compared with prior art, is convenient in oil, gas drilling and the field extensive use of non-excavation.
Four, description of drawings
Accompanying drawing is the structural representation of a kind of embodiment of the utility model.
Five, the specific embodiment
As shown in the figure, a kind of high life sectional rod comprises stem 1, the stem 1 upper end internal thread crossover sub 3 that is threaded, and the stem 1 lower end external screw thread crossover sub 2 that is threaded, internal thread crossover sub 3 outer walls are provided with build-up wear-resistant band 4.
Before drilling rod uses, internal thread crossover sub 3 and external screw thread crossover sub 2 screw with the two ends up and down of stem 1 respectively and can use after being connected, under the protection of build-up wear-resistant band 4, can avoid stem 1 excessive wear in use, protect stem 1 effectively; When internal thread crossover sub 3 and external screw thread crossover sub 2 reach application life, only need dismounting stem 1, change internal thread crossover sub 3 and external screw thread crossover sub 2, can continue to come into operation.
Claims (1)
1. a high life sectional rod comprises stem, it is characterized in that: the stem upper end internal thread crossover sub that is threaded, the stem lower end external screw thread crossover sub that is threaded, internal thread crossover sub outer wall is provided with the build-up wear-resistant band.
