Abstract
The utility model belongs to oilfield exploitation technical field, and particularly a kind of stifled property waterpower pipe nipple temporarily, which comprises at least nipple body, it is characterized in that: the upper end outer wall connected pipes of nipple body, inwall connects orifice plate, orifice plate is evenly equipped with stifled through hole temporarily, is equipped with temporary blocking temporarily in stifled through hole; The upper end outer wall of described nipple body has external screw thread, and the lower end inner wall of oil pipe has internal thread, is threaded connection between nipple body and oil pipe; The upper end inwall of described nipple body has internal thread, and nipple body is threaded with orifice plate by internal thread.This waterpower pipe nipple enters well with completion tubular column, can be in temporary transient sealed condition, without fluid column in oil pipe, effectively prevents the generation of down-hole accident, improves job success ratio.
Description
Technical field
The utility model belongs to oilfield exploitation technical field, particularly a kind of stifled property waterpower pipe nipple temporarily.
Background technology
At present, there is the risk set in well head process of returning that the water yield is large, Safety and Environmental Protection is low and packer is gone into the well in water injection well in oil fields completion practice, thus causes down-hole accident, reduces job success ratio, waste time and energy.
Summary of the invention
The purpose of this utility model is to provide a kind of stifled property waterpower pipe nipple temporarily, and this waterpower pipe nipple enters well with completion tubular column, can be in temporary transient sealed condition, without fluid column in oil pipe, effectively prevents the generation of down-hole accident, improves job success ratio.
The technical scheme that its technical problem of solution of the present utility model adopts is, a kind of water blockoff power pipe nipple temporarily, which comprises at least nipple body, it is characterized in that: the upper end outer wall connected pipes of nipple body, inwall connects orifice plate, orifice plate is evenly equipped with stifled through hole temporarily, is equipped with temporary blocking temporarily in stifled through hole.
The upper end outer wall of described nipple body has external screw thread, and the lower end inner wall of oil pipe has internal thread, is threaded connection between nipple body and oil pipe.
The upper end inwall of described nipple body has internal thread, and nipple body is threaded with orifice plate by internal thread.
Axial arranged along orifice plate of described stifled through hole temporarily.
Described orifice plate is evenly equipped with four stifled through holes temporarily.
The diameter of described stifled temporarily through hole is 10mm.
Described temporary blocking and temporarily interference fit between stifled through hole.
The beneficial effects of the utility model are due to the orifice plate at nipple body internal fixtion, and by the stifled through hole temporarily of blocking shutoff temporarily in orifice plate, slowly can dissolve in down-hole owing to blocking temporarily, soak more than 24 hours under the Temperature-pressure Conditions of stratum, well pressure can be released into below 20MPa by stifled through hole temporarily, meets the completion construction requirement closing note and dispensing well.After temporary blocking is dissolved, do not affect the normal the injecting process of water injection well, this pipe nipple is connected and fixed, and sealing effectively, can ensure production safety environmental protection, avoid having an accident, and improves job success ratio.
Accompanying drawing explanation
Below in conjunction with embodiment accompanying drawing, the utility model is further illustrated.
Fig. 1 is the utility model structural representation.
In figure: 1, nipple body; 2, orifice plate; 3, block temporarily; 4, oil pipe; 5, through hole is blocked up temporarily.
Detailed description of the invention
Embodiment 1
As shown in the utility model structural representation of Fig. 1, a kind of water blockoff power pipe nipple is temporarily provided, which comprises at least nipple body 1, the upper end outer wall connected pipes 4 of nipple body 1, inwall connects orifice plate 2, orifice plate 2 is evenly equipped with stifled through hole 5 temporarily, is equipped with blocking 3 temporarily temporarily in stifled through hole 5.
Temporary blocking 3 is made up of adhesive and solubility medicament, by adjustment component ratio and carry out laboratory test test obtain the site operation that meets require that the formula of dissolution velocity and bearing capacity is made, the shutoff requirement of laboratory test 12 hours bidirectional bearing 30MPa can be met, slowly can dissolve in water.After temporary blocking 3 is dissolved, orifice plate 2 i.e. release pressure, realizes normal completion practice.
This pipe nipple is applicable to the Completion Operations of multilayer injector and dispensing well.During construction, this pipe nipple enters well with completion tubular column, and pipe nipple is in temporary transient sealed condition, without fluid column in oil pipe, can guarantee work progress safety and environmental protection.Go into the well in process, this pipe nipple effectively can reduce the risk of the packer setting caused because of excessive velocities.Tubing string, after design attitude, treats that blocking 3 is dissolved temporarily, realizes normal completion practice.If blocking 3 is not dissolved temporarily, 5 ~ 10MPa can be suppressed in oil pipe, be destroyed.
Embodiment 2
The structure of the present embodiment is substantially identical with embodiment 1 structure, the upper end outer wall of tubular nipple body 1 has external screw thread, the lower end inner wall of oil pipe 4 has internal thread, be threaded connection between nipple body 1 and oil pipe 4, the upper end inwall of nipple body 1 has internal thread, and nipple body 1 is threaded with orifice plate 2 by internal thread.
Temporarily axial arranged along orifice plate 2 of stifled through hole 5, orifice plate 2 is evenly equipped with four stifled through holes 5 temporarily, the diameter of stifled through hole 5 is 10mm temporarily, blocking 3 temporarily and temporarily interference fit between stifled through hole 5.
Claims (7)
1. a temporary water blockoff power pipe nipple, which comprises at least nipple body, it is characterized in that: the upper end outer wall connected pipes of nipple body, and inwall connects orifice plate, orifice plate is evenly equipped with stifled through hole temporarily, is equipped with temporary blocking temporarily in stifled through hole.
2. one according to claim 1 temporary water blockoff power pipe nipple, is characterized in that: the upper end outer wall of described nipple body has external screw thread, and the lower end inner wall of oil pipe has internal thread, is threaded connection between nipple body and oil pipe.
