Description
Technical field
The present invention relates to unconventionaloil pool well cable perforation field of operation, and in particular to a kind of electron pressure test monitoring dress
Put, for the real-time change curve for recording bridge plug and setting, pipe-in-pipe internal pressure power being tested after pitching, be generally mated wireline operation.
Background technology
The bridge plug of Fuling shale gas first stage of the project application, its feature is low for heatproof, and pressure-bearing rank is small, and stream time is not
It is long etc..With the operation of Fuling second phase Productivity Construction, reservoir becomes deeper, underground and pumping when pressure become much larger, hole condition
Become more complicated compared with a phase, requirements at the higher level are proposed to the technical indicator of existing bridge plug and bridge plug setting tool, therefore, it is necessary to
Functional reliability, stability under the conditions of different pressures to bridge plug setting tool and bridge plug body carry out effective evaluation, make it
Technical indicator meets the needs of Fuling work area second phase deep layer shale gas exploitation.
The content of the invention
The purpose of this utility model is to be directed to the above-mentioned state of the art, it is desirable to provide it is a kind of compact-sized, it is easy to operate, and can be true
In fact, pressure history is recorded in real time, directly perceived, science data electricity are provided for the analysis of the technical indicator of bridge plug and bridge plug instrument
Sub- pressure testing monitoring device.
The implementation of the utility model aim is electron pressure test monitoring device, is had and bridge plug pressure-bearing test unit
The top connection of lower contact connection, has the lower contact being connected with union connector, upper and lower connector is connected by casing；There is spiral shell in top connection
There are three pressure relief opening, silk plug mouth and pressure transmitter interface pressure transmission holes in line, side, have seal groove in lower contact.
During using the utility model, seal groove dress O-ring seals, then by from left to right be sequentially connected with mechanical type pressing
Power testing experiment unit, bridge plug pressure-bearing test unit and the utility model, are assembled into bridge plug and set experiment test device；It will need
The bridge plug or bridge plug setting tool of experiment connect, and are put into the set that bridge plug sets experiment test device bridge plug pressure-bearing test unit
In pipe, mechanical compression testing experiment unit and electron pressure test monitoring device each connect pressure transmitter；Air pump drives
Pneumatic pressure pumps, and the highly pressurised liquid of generation is injected from the pressurization mouth of mechanical pressure test test unit side, completes bridge plug
Igniting, set, pitching operation after, highly pressurised liquid is released from pressure relief opening.Pressure transmitter record from highly pressurised liquid injection up to
The change curve of the electron pressure test monitoring device set overpressure of pressure release overall process.
The utility model has the advantage that：
1st, during testing indoors, can truly, monitor pressure change in real time, and record pressure history；
2nd, during testing indoors, it can verify that various bridge plug and the bridge plug setting tool under the conditions of different pressures is set
Whether unidirectional (two-way) load performance afterwards meets construction demand；
3rd, it is compact-sized, it is easy to operate, it is highly practical, it is easy to spread.
