Abstract
The utility model relates to a cleaning drill rod, in particular to a high efficiency cleaning drill rod for a rock cuttings bed. The cleaning drill rod comprises a drill rod body as well as a made buckle and a female buckle that are arranged at the two ends of the drill rod body and is characterized in that a spiral channel structure is arranged around the surface of the drill rod body in a circle. The cleaning drill rod mainly solves the technical problem that the accidents are easily due to the existence of the rock cuttings bed in a well to affect the normal well drilling operation seriously; and the cleaning drill rod can form flow channels that are beneficial for the carrying of the rock cuttings, vortex structures with different sizes and scopes are formed in a hollow ring, and the rock cuttings retained at the lower edge of a shaft can be carried to a large hollow ring, so as to be carried out of the wellhead by the flow in the hollow ring and finally realize the purpose of being beneficial for cleaning the rock cuttings bed.
Description
Technical field
The utility model relates to the cleaning drilling rod, and particularly a kind of high efficiency cutting bed cleans drilling rod.
Background technology
Cutting bed is comparatively general in horizontal well and extended reach well, promptly in eccentric annulus, because drilling fluid speed is less enough big with the landwaste particle diameter in the little annular space, causes borehole wall direction formation cutting bed under the high angle hole section.Yet the existence of cutting bed easily causes the generation of down-hole accident, and then has a strong impact on normal drillng operation.
The utility model content
The purpose of this utility model is to provide a kind of high efficiency cutting bed to clean drilling rod, the existence that it mainly solves cutting bed easily causes the generation of down-hole accident, and then have a strong impact on the technical problem of normal drillng operation, it not only can be formed with and be beneficial to the runner that landwaste carries, and the spiral structure that generation is big or small, scope is different in annular space, it can bring to the landwaste that is trapped in the low limit of pit shaft in the big annular space, so that taken out of well head by annular fluid, finally reaches the purpose of the bed that helps bringing bottoms up.
The utility model solves the problems of the technologies described above the technical scheme that is adopted.
A kind of high efficiency cutting bed cleans drilling rod, and it comprises the drilling rod body and be arranged on the pin thread and the box at drilling rod body two ends that it is characterized in that: described drilling rod body surface is equipped with the spiral channel structure.
Described high efficiency cutting bed cleans drilling rod, and it is characterized in that: the relative drilling rod body axis of the swing angle direction of conduit is at 5 ~ 65 ° in the described spiral channel structure.
Described high efficiency cutting bed cleans drilling rod, and it is characterized in that: the width of conduit is at 30 ~ 80mm in the described spiral channel structure.
Described high efficiency cutting bed cleans drilling rod, and it is characterized in that: the degree of depth of conduit is at 14 ~ 17mm in the described spiral channel structure.
The beneficial effects of the utility model are.
The utility model is compared with general common drilling rod, and it can utilize channel structure can change the movement locus of ring empty flow field and produce the characteristic of vortex, helps taking the purpose that rock efficient improves so that control annular space fluid flow fields reaches.Result of calculation shows that the utility model can improve the flow behavior of annular fluid effectively, strengthens the large rock-carrying ability of annular fluid, reduces the occurrence probability of cutting bed.The utility model has crucial on-the-spot guidance meaning to the cutting bed problem that solves horizontal well and extended reach well high angle hole section annular space and may occur.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the cross-sectional view of spiral channel structure in the utility model.
Fig. 3 is the streamline schematic diagram of the annular fluid of the utility model rotation generation.
Fig. 4 is the fluidal texture figure of conduit arbitrary section inner fluid of the present utility model.
The specific embodiment
See also Fig. 1,2, the utility model discloses a kind of high efficiency cutting bed and clean drilling rod.As shown in the figure: it comprises drilling rod body 1 and is arranged on the pin thread 2 and the box 3 at drilling rod body 1 two ends that described drilling rod body 1 surface is equipped with spiral channel structure 4.
Relative drilling rod body 1 axis direction of the swing angle of conduit is at 5 ~ 65 ° in the described spiral channel structure 4.The width of conduit is at 30 ~ 80mm in the described spiral channel structure 4.The degree of depth of conduit is at 14 ~ 17mm in the described spiral channel structure 4.Above-mentioned parameter can be adjusted according to the length of cleaning drilling rod.
Shown in Fig. 3,4, the utility model channel structure not only can be formed with the runner that is beneficial to the landwaste migration, and improved the tangential velocity of fluid effectively, so the high efficiency cutting bed cleans drilling rod and can improve the net horizontal section annular space effectively and take the rock effect, reduces the possibility that cutting bed forms.
In sum, be preferred embodiment of the present utility model only, be not to be used for limiting practical range of the present utility model, promptly all equivalences of doing according to the content of the utility model claim change and modify, and all should be technology category of the present utility model.
