Description

A kind of downhole temperature, pressure parameter measurement mechanism
Technical field:
The utility model relates to a kind of acquisition and storage device for oil exploitation downhole temperature, pressure parameter, belongs to oil well production testing tool class.
Background technology:
In the productive technology management of oil underground mining, in order rationally to utilize crude oil self heating power resource, need to understand tubing string internal and external temperature and pressure variation and distribution in a period of time oil recovery manufacturing process, producing well temperature is generally at 50 DEG C~150 DEG C, and pressure is in 20~30MPa left and right.Therefore, tester is in high temperature, in high pressure and concuss environment, work, appliance requires reaches heatproof, withstand voltage and concussion requirement, because oil well well depth reaches several kms, need segmentation to carry out temperature test, conventional tester has wire rope banded cable thermometric, pressure measurement instrument is gone into the well, but plant test, require sucker rod to take out from oil well pipe just can be lowered to operation, can not in the time of oil well oil-pumping machine operation, use, therefore, can be retained in for a long time down-hole in the urgent need to one, when with workover treatment, trip out the parameter testing storage apparatus of reading out data with sucker rod or tubing string.
Utility model content:
The purpose of this utility model is to provide a kind of acquisition and storage device (hereinafter to be referred as " measurement mechanism ") of exploiting downhole temperature, pressure parameter, this device can one or morely be used in conjunction with, be arranged on respectively sucker rod or tubing string string different depth place, gather storage and be lowered to temperature, pressure parameter a little.
The technical solution of the utility model is as follows: as shown in Figure 1, this kind of measurement mechanism is by body, plug, sealing ring, draw body, high-temperature battery group, sleeve, device aperture, USB interface, storage chip, micro controller, clock chip, duct, signal and electric power cable, circuit board, temperature transducer, tubing coupling, pressure sensor composition, its structure assembled relation is as follows: the tubing nipple of a standard is made up of tubing coupling and body two parts, the middle part of body and end are all provided with screw thread, a sleeve is installed on body, tightened by a screw thread drawing in the middle of body and body with inner nut again, the one end of drawing body is plane, one end is provided with chamfering in addition, on sleeve, be provided with several device aperture, each device aperture outer end, with screw thread and seal groove, is put into after sealing ring, tightens sealing with interior hexagonal plug, in device aperture, be connected by duct each other, circuit board is housed respectively in these device aperture, temperature pick up, pressure sensor and high-temperature battery group, between electric elements, be connected with circuit board through duct with electric power cable by signal, each single chip circuit plate is provided with particular address coding, is used for the acquisition parameter of different depth point that each device is read to distinguish.
When use, open the power switch of battery pack, system starts timing and thermometric side pressure work, carry out pressure and the temperature calibration of system, carry out again the clock time calibration of single-chip microcomputer, thermometric will be housed, each device aperture of the tubing nipple device of pressure measurement components and parts is put respectively sealing ring well, load onto interior hexagonal plug, tighten with die nut, to on screw thread, to the screw thread of tubing nipple centre, tighten, device is put into pressure pressure testing, arrive after the pressure-bearing standard of oil well design, each measurement mechanism is sent into well site, by technician according to the requirement of thermometric well pressure, the go into the well quantity of measurement mechanism of calculating, the degree of depth that each measurement mechanism is lowered to, on lower oil pipe job execution place, the measurement mechanism of will going into the well carries out body steel seal numbering, order sequences, measure place oil pipe, lower fashionable, measurement mechanism is connected on the female box cupling of oil pipe, on screw threads of coupler, smear stop-leak compound, first-class screwing, links closely with oil pipe tong, because the external diameter of measurement mechanism is larger, tubing string lowering velocity is wanted slowly, to prevent that surge pressure is excessive, is impacted to oil well, when whole measurement mechanisms are with oil pipe lower going-into-well, Single-chip Controlling in each measurement mechanism is the temperature of dark point under interval measurement at regular intervals, pressure and time data, store in storage chip, then, single-chip computer control system enters resting state, take low power operation pattern, like this, the work moving in circles, at measurement mechanism after underground work a period of time, along with clean-out service, play oil pipe, measurement mechanism is taken out one by one, clean, measurement mechanism is placed on workbench, draw body with unloading one by one, with inner hexagon spanner, unload the plug of the device aperture that single chip circuit plate is housed, expose serial ports USB interface, connecting circuit board USB interface and computer are coupled together with data wire, start computer temperature, pressure parameter collecting program, start the computer temperature fetch program, by the data of measurement mechanism single-chip microcomputer memory, be read in computer measurement parameter database, repeat aforesaid operations, by the data of each measurement mechanism of going into the well, all read in computer measurement parameter database, by in the coding of measurement mechanism and lower dark record input computer, so just obtain the survey data of the different depth of this well, can inquire about and comprehensively analyze, to determine optimum oil recovery production technology scheme.
The utility model novel structure, operation setting are conveniently, this device, with in oil well pipe lower going-into-well, can gather for a long time and measure downhole temperature, pressure parameter, and workover treatment rises after flowline and device, temperature, the pressure parameter that can conveniently read different well depths, data acquisition is precisely reliable.
