A kind of novel pipe of testing squeezes apparatus for ash, including: body, top connection, plug, inlet opening, liquid outlet, sliding sleeve, steel ball, shear pin, sealing ring, spheric seat；The cylindrical hollow-core construction of its body, body lower end is provided with the external screw thread that female thread is provided with plug and matches, and top is provided with connection G21/2The top connection of oil pipe, middle and upper part is provided with three groups of uniform square liquid outlets along body peripheral, and bottom is arranged with two groups of inlet openings；Its sliding sleeve is hollow cylindrical structure, sliding sleeve upper surface sets in hemispherical spheric seat, and spheric seat cooperates with steel ball, is respectively provided with one group of sealing ring along sliding sleeve upper and lower, the circular hole that bottom shear pin is provided with through body, sliding sleeve, is positioned at sliding sleeve at the liquid outlet of chamber body.This utility model pressure testing seals reliable, easy to operate, can regulate at any time cut off pin according to testing pipe pressure, and safe and reliable, one-trip string can complete multinomial operation, alleviates worker's labor intensity, has higher promotional value.
Description
Technical field
This utility model relates in petroleum industry in operation well workover work progress, carries out testing pipe, squeezing for oil-water well
The downhole tool of the working procedure checking tubing string tightness such as note ash, a kind of novel pipe of testing squeezes apparatus for ash.
Background technology
It is important operation that oil-water well tests oil pipe before squeezing ash, tests pipe and typically use lower ball base to throw before existing technology squeezing ash
Ball builds the pressure and tests pipe, and steel ball is washed out by anti-flushing well；When another kind is sand washing or drifting, pipe tested in advance by dribbling and ball seat, the most again under
Enter squeezing ash tubing string to carry out squeezing ash construction.Both operations also exist when running into formation leakage or having large diameter oil tube, wash
Ball difficulty or directly can not wash, causes and spray oil pipe pollution environment operation and do over again, and increased the work workload of lower tubular column.
To this end, have developed one can test pipe, can carry out again squeezing ash tests pipe device.
Summary of the invention
The purpose of this utility model is aiming at the deficiency that above-mentioned technical tool exists, and the novel pipe of testing of one designed squeezes
Apparatus for ash.
This utility model is realized by following technical proposals:
This utility model includes: body, top connection, plug, inlet opening, liquid outlet, sliding sleeve, steel ball, shear pin, sealing ring,
Spheric seat；It is novel tests pipe and squeezes the cylindrical hollow-core construction of apparatus for ash body, and body lower end is provided with what female thread and plug were provided with
External screw thread matches, and top is provided with connection G21/2The top connection of oil pipe, middle and upper part along body peripheral be provided with three groups uniform square
Liquid outlet, bottom is arranged with two groups of inlet openings.
Its sliding sleeve is hollow cylindrical structure, and sliding sleeve upper surface sets in hemispherical spheric seat, spheric seat and steel ball phase interworking
Close, be respectively provided with one group of sealing ring along sliding sleeve upper and lower, the circular hole that bottom shear pin is provided with through body, sliding sleeve, sliding sleeve is fixed
Position is at the liquid outlet of chamber body.
The beneficial effects of the utility model are: this utility model is connected to oil pipe foot, under to after projected depth, throw
Φ 45mm steel ball requires the sealing of checking running string according to pressure testing, continues to be forced into 15-16MPa by shear pin after pressure testing is qualified
Cut off (cutting off pin pressure to determine according to the diameter of pin), enclose that the sliding sleeve of fluid apertures is descending to be fallen on plug, be sealed into
Fluid apertures, liquid outlet has all exposed tests pipe operation, can carry out squeezing ash construction.This instrument pressure testing seals reliable, easy to operate,
One-trip string can complete to test pipe, squeezes ash process, alleviates worker's labor intensity, have higher promotional value.
