The utility model discloses a casing pipe gas tightness detects on-spot gas pressure testing detection device of special packer has following advantage: the pressure change inside the packer in the whole working process of setting, pressurizing and unsealing of the packer in a simulated casing and the pressure change of a closed annular space formed by the packer and the casing can be synchronously monitored on site.
Description
Technical Field
The utility model relates to an instrument, more precisely, be an on-spot gas pressure testing detection device of special packer of sleeve pipe gas tightness detection.
Background
At present, the domestic packer for detecting the air tightness of the sleeve pipe has no setting product, and the packer is only stopped at the setting pressure and the pressure bearing condition of the rubber sleeve for liquid pressure test detection when leaving a factory. The packer with the requirement on casing pipe air tightness detection provides the air pressure of a closed ring formed by the packer and the casing pipe after the packer is set, and can meet the design requirement. Only when all parts (a central tube, a piston, an upper rubber sleeve and a lower rubber sleeve) of the packer work normally, and meanwhile, an air inlet valve inside the packer is required to be opened normally under the set pressure, and high-pressure gas enters the closed annulus, the pressure of the closed annulus can be guaranteed to reach the pressure required by detection design (when the airtightness of the sleeve is detected, the pressure cannot be displayed). Therefore, the existing packer performance detection device and technical means in China cannot meet the requirements of detecting the performance and working conditions of the packer of the type.
SUMMERY OF THE UTILITY MODEL
The utility model discloses solve the technical problem that prior art exists to a sleeve pipe gas tightness detects on-the-spot gas pressure testing detection device of special packer is provided.
The above technical problem of the present invention can be solved by the following technical solutions:
the utility model provides a casing gas tightness detects on-the-spot gas pressure testing detection device of special packer, a serial communication port, casing gas tightness detect on-the-spot gas pressure testing detection device of special packer contain a test bench, the test bench on be equipped with a detection sleeve pipe, the detection sleeve pipe on be equipped with a manometer and a pressure sensor, detection sheathed tube one end be equipped with a first cover of rightting, its other end is equipped with a second and rights the cover, first right the cover with the second right the cover through first screw with the detection sleeve pipe be connected, the both sides of detection sleeve pipe be equipped with a plurality of rotatory round pins and fixing bolt.
The utility model discloses a casing pipe gas tightness detects on-spot gas pressure testing detection device of special packer has following advantage: the packer can be synchronously monitored in situ to simulate the pressure change inside the packer in the whole working process of setting, pressurizing and unsetting in a sleeve and the pressure change of a closed annular space formed by the packer and the sleeve, and the packer can be prevented from working abnormally due to transportation and the like because the field detection is carried out by virtue of field auxiliary equipment, is convenient and quick, and can be put into sleeve air tightness detection immediately after the packer is detected to be qualified.
Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without creative efforts.
FIG. 1 is a schematic structural view of the on-site gas pressure test device of the packer special for detecting the airtightness of the casing of the present invention;
fig. 2 is a schematic structural view of the on-site gas pressure test detection device in fig. 1, which is shown in another view.
Detailed Description
The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, and the scope of the present invention can be more clearly and clearly defined.
As shown in fig. 1 and 2, the on-site gas pressure test detection device for the packer special for detecting the airtightness of the casing comprises a test bed 3, a detection casing 4 is arranged on the test bed 3, a pressure gauge 8 and a pressure sensor 9 are arranged on the detection casing 4, a first centralizing sleeve 2 is arranged at one end of the detection casing 4, a second centralizing sleeve 5 is arranged at the other end of the detection casing 4, the first centralizing sleeve 2 and the second centralizing sleeve 5 are connected with the detection casing 4 through first screws 1, and a plurality of rotating pins 6 and fixing bolts 7 are arranged on two sides of the detection casing 4.
The detection steps of the on-site gas pressure test detection device are as follows:
1. helium-nitrogen mixed gas is injected into the packer tool under the control of a pneumatic winch pry, a pressure gauge of the pneumatic winch pry is observed, and the pressure reaches the detection pressure of the design requirement (the prior art sleeve is 35mPa, and the production sleeve is 60 mPa.)
2. And observing whether the pressure of the simulated casing pipe pressure gauge is consistent with the pressure of the pressure gauge of the pneumatic winch pry.
3. And releasing the pressure and unsealing the packer.
4. Analyzing and grinding a pressure curve, determining whether the packer works normally, whether the setting and unsealing processes are normal and smooth, and whether the internal pressure of the packer is consistent with the pressure of the closed annulus, thereby determining whether the packer meets the requirement of detecting the air tightness of the casing.
The on-site gas pressure test detection device of the special packer for detecting the airtightness of the sleeve is simple in structure, obvious in effect, low in cost and high in practicability.
Without being limited thereto, any changes or substitutions which are not thought of through creative efforts should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope defined by the claims.
