Description
Technical field
This utility model relates to oil drilling aid technical field.
Background technology
During exploring for oil, petroleum casing pipe for oil well is hollow structure, the impurity such as substantial amounts of earth can be left on the inwall of sleeve pipe during using, in order to remove the impurity of the inside, it is usually at present to insert with some better simply clubs and is purged, elimination effect is poor, inefficiency, remove the most uneven, the most thorough, the inwall of sleeve pipe can be caused damage the most in some cases, so for the problems referred to above, a kind of instrument is needed now to can solve the problem that the problems referred to above, realize the convenient and swift high efficiency inwall impurity to sleeve pipe to clear up.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of scraper for petroleum casing pipe inwall, and the earth on internal surface of sleeve pipe can quickly effectively comprehensively be cleared up by this scraper, convenient and swift.
For solving the problems referred to above, this utility model adopts the technical scheme that: a kind of scraper for petroleum casing pipe inwall, this scraper includes the cylinder base that cross section is annular, upper and lower side at cylinder base is connected to the upper scraping ring that is coaxially disposed with cylinder base and lower scraping ring, the internal-and external diameter of described upper scraping ring and lower scraping ring is the most equal, described upper scraping ring and lower scraping ring align up and down, the internal diameter of described upper scraping ring and lower scraping ring is equal to the internal diameter of cylinder base, it is semicircular inner groovy with a ring cross-section at the annular outer wall of described upper scraping ring and lower scraping ring, a coil spring it is laid with in described inner groovy, the outer circumference of described spring is exposed to outside inner groovy, multiple arc-shaped spring piece protruding laterally it is also associated with between the bottom edge and the top edge of lower scraping ring of upper scraping ring, the outer surface of described arc-shaped spring piece is provided with scraping edge.
Preferably, described spring is fixed in inner groovy, and described multiple arc-shaped spring pieces are uniformly distributed along the circumferencial direction of upper scraping ring and lower scraping ring.
Preferably, described scraping edge is horizontally disposed with, and is provided with multiple scraping edge on each arc-shaped spring piece, and described multiple scraping edge are evenly arranged from top to bottom along the length direction of arc-shaped spring piece.
This utility model is brought to provide the benefit that, this scraper is with spring and scraping edge, clod on internal surface of sleeve pipe and other impurity effectively can be cleared up, scraping edge is for removing the clod that the cohesive force being not easily cleaned is bigger, clod or other impurity of relatively easy to clean cleared up the most on a large scale by spring, and cleaning is efficiently, the most convenient and swift, the speed of the cleaning greatly speeded up, it is ensured that the life-time service of sleeve pipe.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein, 1, cylinder base, 2, upper scraping ring, 3, lower scraping ring, 4, spring, 5, arc-shaped spring piece, 6, scraping edge.
Detailed description of the invention
nullWith detailed description of the invention, this utility model is described in further detail below in conjunction with the accompanying drawings: as shown in Figure 1，A kind of scraper for petroleum casing pipe inwall，This scraper includes the cylinder base 1 that cross section is annular，Upper and lower side at cylinder base 1 is connected to the upper scraping ring 2 that is coaxially disposed with cylinder base 1 and lower scraping ring 3，The internal-and external diameter of described upper scraping ring 2 and lower scraping ring 3 is the most equal，Described upper scraping ring 2 and lower scraping ring about 3 align，The internal diameter of described upper scraping ring 2 and lower scraping ring 3 is equal to the internal diameter of cylinder base 1，It is semicircular inner groovy with a ring cross-section at the annular outer wall of described upper scraping ring 2 and lower scraping ring 3，A coil spring 4 it is laid with in described inner groovy，The outer circumference of described spring 4 is exposed to outside inner groovy，Multiple arc-shaped spring piece 5 protruding laterally it is also associated with between the bottom edge and the top edge of lower scraping ring 3 of upper scraping ring 2，The outer surface of described arc-shaped spring piece 5 is provided with scraping edge 6.
Spring 4 is fixed in inner groovy, and described multiple arc-shaped spring pieces 5 are uniformly distributed along the circumferencial direction of upper scraping ring 2 and lower scraping ring 3.Scraping edge 6 is horizontally disposed with, and is provided with multiple scraping edge 6 on each arc-shaped spring piece 5, and described multiple scraping edge 6 are evenly arranged from top to bottom along the length direction of arc-shaped spring piece 5.
nullThis scraper is with upper scraping ring 2 and lower scraping ring 3，Both are connected by middle cylinder base 1，Upper scraping ring 2 is identical with the structure of lower scraping ring 3，The annular outer wall at both edges is provided with inner groovy，This inner groovy is used to accommodate spring 4，Spring 4 is end to end cyclic structure，One week is just laid in its inner groovy that is laid in，But spring 4 is not completely installed in inner groovy，Spring 4 periphery has half to be exposed to outside inner groovy，Connect between upper scraping ring 2 and lower scraping ring 3 and have arc-shaped spring piece 5，It is the most protruding，And with scraping edge 6，When in use scraper is put into the inside of sleeve pipe，During putting into，The inner wall compressive of spring 4 sleeve in upper scraping ring 2 and lower scraping ring 3 inner groovy tightens up，Make to produce between spring 4 and inwall an extruding force，In like manner arc-shaped spring piece 5 is retracted into the inside of sleeve pipe after being also extruded，And produce an extruding force between the inwall of sleeve pipe，So promote this scraper，Scraping edge 6 on the most upper and lower spring 4 and medial arc spring leaf 5 carries out cleaning to inwall the most simultaneously and strikes off，Scraping edge 6 is for removing the clod that the cohesive force being not easily cleaned is bigger，Clod or other impurity of relatively easy to clean cleared up the most on a large scale by spring 4.
This utility model is brought to provide the benefit that, this scraper is with spring and scraping edge, clod on internal surface of sleeve pipe and other impurity effectively can be cleared up, scraping edge is for removing the clod that the cohesive force being not easily cleaned is bigger, clod or other impurity of relatively easy to clean cleared up the most on a large scale by spring, and cleaning is efficiently, the most convenient and swift, the speed of the cleaning greatly speeded up, it is ensured that the life-time service of sleeve pipe.
