Abstract
(B, ) the utility model relates to a (b) (b) among oil gas field oil development and the prospecting, a kind of using during (b) (b) well drilling well completion is indicating device technical field in the pit, is a well cementation plug position indicator device, its (b) (b) is including body, fixed loop and sign ring, this is internal to have axial passage, the inside inner ring platform that is equipped with of body, sign ring seat be at the inner ring bench, this internal have through screw fixed mounting compress tightly the fixed loop at the inner ring bench with the sign ring. (B, ) (b) the utility model has the advantages of reasonable and compact structure, convenient to use prevents that the grout from replacing the sky, prevents to stay the cement stopper of overlength, can in time fall the discharge capacity before pressing and realizes the soft pressure of bumping bumping, avoids bumping firmly the pressure to the injury of equipment, judges for accident in the pit and provides the basis. (B, )
Description
Technical field
the utility model relates in oil gas field oil development and geological prospecting, and a kind of down-hole indicating device technical field used during drilling completion is a kind of cementing plug position indicator.
Background technology
well cementing operation is the important technical being connected drilling well and oil producing operation, and meanwhile, well cementation is again the underground work of dangerous, and therefore, the success or not of well cementing operation, will directly cause the success or failure of a bite well.At present, that explores along with shale gas, fine and close wet goods unconventionaloil pool field deepens continuously, and people are for carrying out the research of such Reservoir Development also in continuous reinforcement.Therefore, being badly in need of one can carry out indicators track to Position on rubber stopper in well cementing operation, can dodge the device that the complex situations such as solidifying and accident carry out early warning to casing leak, cementing leakage, annular plug, sausage-filling, cementing for empty, cement paste.
Summary of the invention
the utility model provides a kind of cementing plug position indicator, overcomes the deficiency of above-mentioned prior art, and it effectively can solve Position on rubber stopper in well cementing operation can not carry out the problem of indicators track and accident early warning.
the technical solution of the utility model is realized by following measures: a kind of cementing plug position indicator, comprise body, retainer ring and identification rings, axial passage is had in body, body interior is provided with interior land, mark ring seat, in interior land, is installed with the retainer ring be pressed on by identification rings in interior land in body by screw thread.
here is the further optimization and/or improvements to above-mentioned utility model technical scheme:
the bottom of above-mentioned body is provided with external screw thread, and top is provided with internal thread.
above-mentioned retainer ring is polytetrafluoroethylmaterial material retainer ring.
above-mentioned identification rings is tempered glass identification rings.
above-mentioned body can be casing short joint.
the utility model reasonable and compact in structure, easy to use, prevent cement paste from replacing sky, prevent from staying long cement plug, discharge capacity can be fallen in time realize soft bruising before bruising, avoid hard bruising to the injury of equipment, for down-hole accident judges to provide foundation.
Accompanying drawing explanation
accompanying drawing 1 is that the master of the utility model most preferred embodiment looks half section structural representation.
coding in accompanying drawing is respectively: 1 is body, and 2 is retainer ring, and 3 is identification rings, and 4 is interior land, and 5 is axial passage.
Detailed description of the invention
the utility model by the restriction of following embodiment, can not determine concrete embodiment according to the technical solution of the utility model and actual conditions.
in the utility model, for convenience of description, the description of the relative position relation of each parts is all be described according to the Butut mode of Figure of description, as: the position relationship of upper and lower, left and right etc. determines according to the Butut direction of Figure of description.
below in conjunction with embodiment and accompanying drawing, the utility model is further described:
as shown in Figure 1, this cementing plug position indicator comprises body 1, retainer ring 2 and identification rings 3, axial passage 5 is had in body 1, body 1 inside is provided with interior land 4, identification rings 3, in interior land 4, is installed with the retainer ring 2 be pressed on by identification rings 3 in interior land 4 in body 1 by screw thread.In solid downhole pipeline process, by cementing plug position indicator together with pipe string one remove into, in the process that well cementation replaces, plug is descending, time cementing plug position indicator, plug is stuck on the identification rings 3 of cementing plug position indicator, after pressure raises 1MPa, identification rings 3 breakage becomes diameter to be less than the granule of 3mm, and plug continues descending, the position of plug to band cementing plug position indicator can be found out from ground pressure table, thus judge the run location of plug.
according to actual needs, above-mentioned cementing plug position indicator can be made further optimization and/or improvements:
as shown in Figure 1, the bottom of body 1 is provided with external screw thread, and top is provided with internal thread.Like this, by other pipe fittings that are threaded.
as required, retainer ring 2 is polytetrafluoroethylmaterial material retainer ring.
as required, identification rings 3 is tempered glass identification rings.
as required, body 1 is casing short joint.
above technical characteristic constitutes most preferred embodiment of the present utility model, and it has stronger compliance and best implementation result, can increase and decrease non-essential technical characteristic according to actual needs, meet the demand of different situations.
Claims (9)
