Abstract
The utility model discloses an electronic pressure seal inspection instrument, which can be used for the seal inspection test of an oil field water well for judging whether a downhole packer is sealed. The electronic pressure seal inspection instrument is composed of an electronic pressure meter, a sealing device and a positioning device, wherein, the electronic pressure meter is provided with pressure sensors 1a and 1b, a circuit 1c, a battery assembly 1d, an entrance pressure hole 1e and another bearing chamber 1f. The sealing device is provided with an entrance pressure hole 2a. The positioning device is provided with an entrance pressure hole 3a. The electronic pressure meter 1 is arranged in the sealing device. The design of the electronic pressure seal inspection instrument shortens the length of the complete set electronic pressure seal inspection instrument. The electronic pressure seal inspection instrument has the advantage of flexible and convenient use, and reduces the cost of production and use. The seal inspection test can be carried out by two pressure test passages, and the electronic pressure seal inspection instrument realizes that one instrument can synchronously test the pressure value of the upper end and the lower end of a seal segment. One circuit can simultaneously process two paths of pressure signals. Two groups of data can return to the same interface by circuit and software processing. The data can be analysed and judged in the same graph. The utility model can enhance test success ratio and accuracy.
Description
The utility model relates to a kind of pressure detection instrument, particularly aims at water injection well and tests envelope technology and design, be used to a kind of electron pressure seal-checking instrument of judging whether down-hole packer seals.
At present, be used to judge whether down-hole packer seal that to test the envelope test be to connect two pressure gauges respectively at the seal section upper/lower terminal, two pressure gauge while RIH detect two groups of pressure curves respectively, judge the sealing condition of down-hole packer with the comparison line that reclaims two songs.The problem that exists is that the testing tool length dimension is big, and delivery is difficult, failure rate is high, and can't realize data sync.
The purpose of this utility model provides a kind of electron pressure seal-checking instrument, and this instrument is realized the instrument synchronous detection seal section force value at two ends up and down by two pressure detection passages, handles the two-way pressure signal simultaneously with a circuit, realizes data sync; Shorten the length dimension of testing tool, reduce and produce and use cost, improve the test success ratio.
The purpose of this utility model is achieved in that the electron pressure seal-checking instrument is made up of electronic pressure gauge 1, packoff 2, locating device 3, electronic pressure gauge 1 is equipped with two pressure transducer 1a, 1b, circuit 1c and battery component 1d, and entrance pressure hole 1e and another pressure pocket 1f are arranged; Have entrance pressure hole 2a on the packoff 2; Entrance pressure hole 3a is arranged on the locating device 3, and electronic pressure gauge 1 places in the packoff 2.
The electron pressure seal-checking instrument is when the down-hole is delivered, and locating device 3 makes it to be seated in the target interval, and packoff 2 is separated the upper and lower end pressure of this interval.The pressure of upper end acts on the sensor 1a by entrance pressure hole 2a on the packoff 2 and the entrance pressure hole 1e on the electronic pressure gauge 1, and the pressure of lower end acts on the sensor 1b by another pressure pocket 1f that the entrance pressure hole 3a on the locating device 3 enters on the electronic pressure gauge 1. Pressure transducer 1a, 1b send the pressure signal that is detected into circuit 1c respectively and carry out computing and storage.
The beneficial effects of the utility model: electronic pressure gauge places in the packoff, makes the contraction in length of a whole set of seal-checking instrument, and is flexible and convenient to use, reduced production and use cost; This design has two pressure detection passages, test the envelope test by two pressure detection passages, can realize the instrument synchronous detection seal section force value at two ends up and down, use a circuit to handle the two-way pressure signal simultaneously, two groups of data are by circuit, software processes, can be played back under the same interface, carry out analysis and judgement in same chart, can realize data sync fully, test success ratio and accuracy all are improved.
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is a structural representation of the present utility model.
1 electronic pressure gauge 1a, 3 locating device 3a entrance pressure holes, 1f pressure pocket 2 packoff 2a entrance pressure holes, 1b pressure transducer 1c circuit 1d battery component 1e entrance pressure hole among the figure
As shown in Figure 1, electronic pressure gauge 1 in the electron pressure seal-checking instrument is equipped with upper and lower two pressure transducer 1a, 1b, pressure transducer adopts resistance-strain type or diffuse si formula, and circuit 1c is to be the sampling computing and the memory circuit of core parts by single-chip microcomputer, and 1d provides power supply by battery component; Entrance pressure hole 1e and another pressure pocket 1f introduce the pressure at two ends the pressure-sensitive cavity of pressure transducer 1a, 1b respectively.Have entrance pressure hole 2a on the packoff 2, entrance pressure hole 3a is arranged on the locating device 3.During test, packoff 2 is separated the upper and lower end pressure of target interval.The pressure of upper end acts on the sensor 1a by entrance pressure hole 2a on the packoff 2 and the entrance pressure hole 1e on the electronic pressure gauge 1, and the pressure of lower end acts on the sensor 1b by another pressure pocket 1f that the entrance pressure hole 3a on the locating device 3 enters on the electronic pressure gauge 1. Pressure transducer 1a, 1b send the pressure signal that is detected into circuit 1c respectively and carry out computing and storage.
