Abstract
The utility model discloses a release for oil casing drilling, which comprises an outer barrel. Shear pins are disposed on the outer barrel, a slide bushing is arranged in the outer barrel, and one end of the slide bushing is provided with a steel ball while the other end of the slide bushing is connected with an elastic claw. The release is characterized in that the slide bushing is provided with shearing parts, and the shear pins are separated from the outer barrel via the shearing parts. By means of adopting the technical scheme, the total release is simple in structure, is more convenient during usage. In addition, the shear pins are separated from the outer barrel conveniently after pressure is applied onto the slide bushing, so that underground pipelines can be packed by the release under pressure.
Description
Technical field
The utility model relates to a kind of petroleum drilling and mining apparatus, specifically relates to a kind of petroleum casing pipe drilling well and gives up.
Background technology
At present, in the oil field development, formed the down-hole water-plugging technique of a cover comparative maturity at home, packer has become the most effective means of water pack off technological measure, and back-off packer also just more seems important.But back-off packer but lags behind the development of packer water-plugging technique as the class in the packer, is in a kind of dead state.The ubiquitous problem of traditional back-off packer is a complex structure, assembly nearly three, 40 kind, all bring difficulty for production and processing, construction and operation.
The utility model content
Problem to be solved in the utility model provides a kind of petroleum casing pipe drilling well simple in structure, easy to use with giving up.
For addressing the above problem, the technical scheme that the utility model adopted is:
A kind of petroleum casing pipe drilling well comprises urceolus with giving up, and urceolus is provided with and cuts off, and is provided with sliding sleeve in the urceolus, and an end of sliding sleeve is provided with steel ball, and an end of sliding sleeve is connected with elastic claw, it is characterized in that: described sliding sleeve is provided with and can makes the part of cutting off that cuts off with the urceolus disengaging.
As a kind of improvement:
The described part of cutting off is positioned at the end that sliding sleeve is provided with steel ball.
Describedly cut off the cylindrical setting of part.
The described quantity that cuts off is several, and each cuts off corresponding one and cuts off part.
The utility model makes whole give up simple in structure by adopting technique scheme, and also more convenient in use, after sliding sleeve is exerted pressure, cuts off and is convenient to break away from urceolus, under the effect of ambient pressure the down-hole pipeline is carried out shutoff.
Below in conjunction with accompanying drawing the utility model is further described.
Description of drawings
Accompanying drawing 1 for the petroleum casing pipe drilling well with the structural representation of giving up under the initial state;
Accompanying drawing 2 for the petroleum casing pipe drilling well with the structural representation of the work of giving up after finishing;
Accompanying drawing 3 is an A place partial enlarged drawing in the accompanying drawing 1.
Among the figure: the 1-urceolus; 2-cuts off; The 3-plug; 4-red copper pad; The 5-sliding sleeve; The 6-spring detent; The 7-steel ball; 8-cuts off part.
The specific embodiment
Embodiment: as depicted in figs. 1 and 2, a kind of petroleum casing pipe drilling well comprises urceolus 1 with giving up, and urceolus 1 is provided with and cuts off 2, cuts off 2 and also is provided with plug 3, cut off 2 and urceolus 1 between be provided with red copper pad 4.Cutting off for 2 whens beginning welds with urceolus 1, and welding manner is generally spot welding, is about to cut off 2 and can be fixed on urceolus 1 and gets final product, and strength of fixation is little.
Be provided with sliding sleeve 5 in the urceolus 1, an end of sliding sleeve 5 is provided with steel ball 7, and an end of sliding sleeve 5 is connected with elastic claw 6, and described sliding sleeve 5 is provided with to make and cuts off 2 and cut off part 8 with urceolus 1 breaks away from.
As shown in Figure 3, the described part 8 of cutting off is positioned at the end that sliding sleeve 5 is provided with steel ball 7, cuts off part 8 cylindrical settings, cut off 2 quantity and be several, each cut off 2 corresponding one cut off part 8.
Use: according to detection, to give up and transfer to assigned address, in urceolus 1, exert pressure then, as injecting mud, promoting sliding sleeve 5 moves down, in folding process, cut off part 8 through cutting off 2, cut off part 8 and will cut off 2 disengagings from urceolus 1, along with continuing to be displaced downwardly to, sliding sleeve 5 stops, cut off 2 places that under ambient pressure, need repair and repair, whole process simple and fast, high efficiency pipeline.
