Abstract
The utility model relates to metrology tools, particularly to an automatic measuring apparatus for a tubular pipe of a downhole operation locale. The utility model is characterized in that a double-direction magnetic induction probe (1) is fixed in a diplopore of an additional flange (4) which is connected with a well mouth flange (5). The double-direction magnetic induction probe (1) is electrically connected with a measurement unit (3). The automatic measuring apparatus for a tubular pipe has the advantages of high automatization degree, high precision and durability in locales.
Description
Technical field
The utility model relates to metering outfit, particularly the on-the-spot tubing string of borehole operation is measured device automatically.
Background technology
Oil pipe in the borehole operation process, the surveying of beam hanger all are manually-operated for many years, generally need three people to cooperate and measure just and can finish, and " three measure three counterparts " wanted in construction at every turn, and more time-consuming, error is big, and automaticity is low.In recent years, though instrument such as laser length measurement registering instrument has appearred, because factors such as its precision height, cost height all are not suitable for field construction.
Summary of the invention
The purpose of this utility model provides a kind of tubing string and measures device automatically, its automaticity height, degree of accuracy height, on-the-spot durable.
The purpose of this utility model is to realize like this, design a kind of tubing string and measure device automatically, it is characterized in that: two-way magnetic induction probe 1 is fixed in the diplopore of additional flange 4, and additional flange 4 is connected with wellhead flange 5, and two-way magnetic induction is popped one's head in and 1 is electrically connected with measuring unit 3.
Described additional flange 4 is the disks that are connected with two spacing pins 7 on former wellhead flange 5.
The magnetic of described magnetic induction probe 1 detects distance greater than 10CM.
Described measuring unit comprises timing circuit 2, measuring amplifier 6, display circuit 8, and two-way magnetic induction probe 1 is electrically connected with measuring amplifier 6, and measuring amplifier 6 is electrically connected with timing circuit 2 input ends; Timing circuit 2 is electrically connected with display circuit 8.
Described timing circuit 2 is single-chip microcomputers.
Characteristics of the present utility model are: owing to can cause the magnetic induction signal when going into well casing post and down-hole annex by magnetic induction, this signal is amplified by measuring amplifier, deliver to timing circuit, the timing circuit timing of starting working when the magnetic induction signal produces, the well casing post of going into of fixed speed just can be by the length that calculates it like this, this method circuit is simple, the reliability height.
Description of drawings
The utility model is described in further detail below in conjunction with the embodiment accompanying drawing:
Fig. 1 is the structural representation of embodiment;
Fig. 2 is a circuit block diagram.
Among the figure: 1, two-way magnetic induction probe; 2, timing circuit; 3, measuring unit; 4, additional flange; 5, wellhead flange; 6, measuring amplifier; 7, pin; 8, display circuit; 9, tubing string and down-hole annex.
Embodiment
Embodiment as shown in Figures 1 and 2, two-way magnetic induction probe 1 is installed in the diplopore of additional flange, additional flange is connected with wellhead flange, additional flange 4 is to open the well head back seat has two spacing pins 7 on former wellhead flange 5 disk, go into well casing post and down-hole annex 9 by two-way magnetic induction 1 o'clock, two-way magnetic induction 1 obtains electric signal, and two-way magnetic induction probe 1 is electrically connected with measuring unit 3.Amplified by the measuring amplifier in the measuring unit 36, and calculate the length of come in and go out well casing posts and down-hole annex 9 by timing circuit 2, here timing circuit 2 can be a single-chip microcomputer, and single-chip microcomputer is shown length measured by display circuit 8.The magnetic induction radius of magnetic induction probe 1 is greater than 10CM in general, and both magnetic detects distance greater than 10CM, can effectively feel signal and measuring so that go into well casing post and down-hole annex 9.
As shown in Figure 2, measuring unit comprises timing circuit 2, measuring amplifier 6, display circuit 8, and two-way magnetic induction probe 1 is electrically connected with measuring amplifier 6, and measuring amplifier 6 is electrically connected with timing circuit 2 input ends; Timing circuit 2 is electrically connected with display circuit 8.Because the magnetic induction technology is very universal technology with the one-chip computer that is used for data processing, cost is low, and highly sensitive admission data are accurate, easy for installation, easy to utilize.
