Abstract
The utility model belongs to a rubber tube pressure tester which enters a well and plays the divided function. The utility model is suitable for testing pressure for rubber tubes of different specifications. One end of a sliding sleeve (5) on the pressure tester is fixed on a central screw rod (11), and a nut (12) on one end of the sliding sleeve (5) is fixed. The sliding sleeve (5) is assembled with a spindle sleeve (2) in a sliding mode. The utility model can be freely flexed. The length of a rubber tube for testing pressure can be between 900 and 1500 or is determined according to the requirement of a user. The utility model can simulate the condition of underground work and can actually reflect the expansional state of a tool, which is convenient for ground observation and detection. After the pressure of the rubber tube is tested, the sealing pressure is exact, the using work efficiency and the reliability of the tool which enters a well can be ensured, and the well cementing quality can be improved. The operation of the utility model is flexible and convenient, labor intensity can be reduced, time can be saved, and cost can be economized.
Description
(1) technical field:
The utility model belongs to the packing element pressure testing device of making compartmentation under the lower going-into-well of oil field.
(2) background technology:
The oil field gets out running casing behind the uncased hole, by injecting grout sealing casing annulus.The well layering well cementation that has according to design, layering well cementation section upper and lower used the Tubing Packer packing.The differential external casing packer of PYF-140 balance that adopts is the national patented product of grand celebration drilling engineering Institute for Research and Technology at present, and this product is to prevent the interlayer play, improves the cementing tool of cementing quality.Wherein, the harmless expansion before the packing element parts will be tested and dispatch from the factory detects.Because packing element is rubber components, axial error is bigger, and the user to propose effective closure size scope of packing element sometimes bigger.Be to manufacture and design different pressure testing devices respectively at different packing element length in the past, labour intensity is big, and causes unnecessary waste.
(3) utility model content:
Technical problem to be solved in the utility model is at the problem that exists in the background technology, and a kind of packing element pressure testing device of suitable different size is provided.
The invention for solving the technical problem can reach by following technical solution: the end at the pressure testing device upper sliding sleeve is fixed on the leading screw of center, and its top nut is fixed; Between sliding sleeve and the axle cover is slidable fit.
Owing on cunning cover central axis, leading screw is installed, axial force by screw mandrel makes sliding sleeve produce axial displacement along the axle cover, the axial location of scalable sliding sleeve, make the passive slave part of pressure testing packing element one end also follow generation axial displacement, the different size packing element can be assembled pressure testing, thereby reaches purpose of design.
The utility model is compared with background technology has following beneficial effect: this device retractable, and pressure testing packing element length can be between 900-1500 or according to customer requirements; But working condition under this device simulation well truly reflects the swelling state of instrument, is convenient to ground observation and detection; Glue tube base seal pressure after this device pressure testing is accurate, can guarantee that going into the well of instrument makes recruitment rate reliability, thereby improves cementing quality; This device flexible operation, convenience can reduce labour intensity, save time, and save cost.
(4) description of drawings:
Accompanying drawing is that this device is installed schematic diagram.
(5) embodiment:
Below in conjunction with the drawings and specific embodiments will the utility model is described in further detail:
Shown in figure, contain on the device liquid inlet joint 1, tested moulding tube 6, sliding sleeve 5, axle cover 2 and between O-ring seal 4, the utility model be a end at sliding sleeve 5 on dead center screw mandrel 11, its top nut 12 is fixed; Be sliding assembling between sliding sleeve 5 and the axle cover 2.
By the pressure testing device of above forecast scheme configuration, pressure testing packing element 6 is enclosed within on the sliding sleeve 5, an end of packing element 6 is loaded onto joint 3 on an end of axle cover 2, the other end is installed lower sub 9, attachment screw 8, pressure cap 10 in an end of sliding sleeve 5; It outside the pressure testing packing element 6 explosion-proof vent 7.
Claims (1)
- A kind of packing element pressure testing device that relates to contains liquid inlet joint (1), tested moulding tube (6), sliding sleeve (5), axle cover (2) on the device, it is characterized in that: an end of sliding sleeve (5) is fixed on the center leading screw (11), and its top nut (12) is fixed; Between sliding sleeve (5) and the axle cover (2) is slidable fit.
