Abstract
The utility model provides a kind of oil drill rocker trip-proof device, it is characterized in that comprising left hand thread button bores, left hand thread retaining ring pipe, transit joint, casing string, cementing head, it is left hand thread structure on the upside of described transit joint, downside is left hand thread structure, described left hand thread button bores and is connected with left hand thread retaining ring pipe, be connected with casing string on the downside of described left hand thread retaining ring pipe, described casing string is connected by transit joint with cementing head, described casing string is connected with on the upside of transit joint, the utility model is left-hand thread button Anti-slip cover tubular structure, fundamentally solve the back-off and the phenomenon that releases that cause because of frictional force, the generation of peril in less work progress, ensureing the life security that also ensure that staff while construction is normally carried out, there is huge economic benefit and application prospect widely.
Description
Technical field
The utility model relates to petroleum exploration field, particularly relates to a kind of oil drill rocker trip-proof device.
Background technology
In part drillng operation, the screw buckle of well cementing casing pipe junction releases, the phenomenon of threading off happens occasionally at each elephant, and accident generation post-processing difficulty is large, seriously have impact on carrying out smoothly of next spudding well operation.The main cause causing this type of accident to occur is: due to outside tube water earth rubber knot poor quality during well cementation, there is the phenomenon of pipe overcoat tube wall cement-free in part tubular, when the frequent contact friction internal surface of sleeve pipe of drill string, by the effect of frictional force between drill string and sleeve pipe, part tubular section easily releases and phenomenon of threading off, and the phenomenon that releases and thread off mainly occurs in drilling out and follow-up drilling process.The button-type of these cannula connection is dextrorotation retaining ring pipe, at brill ash plug with when continuing to creep into, when contact friction internal surface of sleeve pipe frequent due to drill string, by the effect of frictional force between drill string and sleeve pipe, dextrorotation retaining ring tube portion casing section easily releases and the phenomenon such as dropout, common phenomenon sleeve pipe loosens, thread off, top and the bottom sleeve pipe is thrown off, dislocation, causes the phenomenons such as trip-out, slacking off, chance card.At present, thread off to prevent sleeve pipe, at pipe string structure bottom place, generally all use a kind of special bonding agent to carry out splicing before upper screw buckle to fix, although take this measure, but still have generation at drilling out and follow-up drilling process middle sleeve dropout event, this way can not play good anticreep effect.
Summary of the invention
According to above technical problem, the utility model provides a kind of oil drill rocker trip-proof device, it is characterized in that comprising left hand thread button brill, left hand thread retaining ring pipe, transit joint, casing string, cementing head, it is left hand thread structure on the upside of described transit joint, downside is right-handed thread structure, described left hand thread button bores and is connected with left hand thread retaining ring pipe, be connected with casing string on the downside of described left hand thread retaining ring pipe, described casing string is connected by transit joint with cementing head, described casing string is connected with on the upside of transit joint, and described cementing head is connected with on the downside of transit joint.
The beneficial effects of the utility model are: be left hand thread structure on the upside of transition head of the present utility model, downside is right-handed thread structure, so when carrying out disassembling section, if left hand thread retaining ring pipe turns clockwise, the screw buckle of sleeve pipe is just in screw buckle pulled-up condition, just can avoid so like this because of lower rotational, vibrations and cause casing threads button to release and cause sleeve pipe dropout accident to occur when operating.The utility model has broken the concept of conventional right threaded sleeve design, not only can effectively solve because geological condition is complicated, avoid well off quality time occur the problem such as back-off, dropout, and any impact is not produced on the processing technology of traditional construction technology and tubing, the process of construction can not be affected, can not make troubles to construction.The utility model is left-hand thread button Anti-slip cover tubular structure, fundamentally solve the back-off and the phenomenon that releases that cause because of frictional force, decrease the generation of peril in work progress, ensureing to also ensure that the life security of staff while construction is normally carried out that there is huge economic benefit and application prospect widely.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
As Fig. 1, left hand thread button brill-1, left hand thread retaining ring pipe-2, transit joint-3, casing string-4, cementing head-5.
Detailed description of the invention
According to Fig. 1, the utility model is further described:
Embodiment 1
During installation, first left hand thread structure is set to by the upside of transit joint 3, downside is set to left hand thread structure, then left hand thread button is bored 1 to be connected with left hand thread retaining ring pipe 2, then be connected on the downside of left hand thread retaining ring pipe 2 with casing string 4, casing string 4 is connected, during connection by transit joint 3 with cementing head 5, be connected on the upside of casing string 4 and transit joint 3, cementing head 5 is connected with on the downside of transit joint 3.
Embodiment 2
When the utility model uses, the upper end of transit joint 3 is connected with cementing head 5, adopt right-handed thread box, lower end is connected with casing string 4, adopt left hand thread pin thread, when constructing can there are vibrations or rotate in cementing head 5, because cementing head is traditional right-handed thread structure, so produce clockwise movement after during its vibrations, also drive transit joint 3 and casing string 4 to move simultaneously, because casing string 4 is left-hand thread structure, clockwise movement can not make it loosen, it can be made on the contrary to tighten, avoid the thing come off because of loosening to occur, ensure that operation procedure normally runs.
The above is only preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvement, these improvement also should be considered as protection domain of the present utility model.
