Detailed description of the invention
Embodiment 1:
As shown in Figure 1, the invention provides a kind of oil field based on Hall effect and automatically receive ball count method, the spherical pig 4 that the method utilization inside is implanted with metallic object is when being provided with honeywell switch sensor 1 and being built with the receipts ball count device in magnetic field, magnetic induction line in meeting cutting magnetic field, honeywell switch sensor 1 can be recorded changes of magnetic field count simultaneously.
The present invention receives in ball process at automatic spherical pig receiving device, utilize the spherical pig of implanting a small amount of metal, according to Hall effect principle, in the time that special spherical pig passes through to build magnetic field, magnetic induction line in meeting cutting magnetic field, honeywell switch sensor can be recorded this slight changes of magnetic field, thereby accurately ball is received in prompting, receive ball count.
Embodiment 2:
On the basis of embodiment 1, described receipts ball count device comprises the isolated pipe 2 that docks with automatic spherical pig receiving device and pass through described spherical pig 4, the left side of this isolated pipe 2 is positioned at pipeline external and is provided with magnet 3, and the right side of isolated pipe 2 is positioned at pipeline external and is provided with honeywell switch sensor 1.
Described magnet 3 is permanent magnet, and the left end of magnet is the S utmost point, and right-hand member is the N utmost point, selects its magnetic force of permanent magnet stable, and magnetic force can not be decayed. The cuboid that is shaped as strip of described magnet 3, and it is vertical with the central axis of isolated pipe 2, and this rectangular shape is convenient to form stable and uniform and stronger magnetic field. Described magnet 3 is with honeywell switch sensor cross direction profiles in the left and right sides of isolated pipe 2, and the two is positioned at same level position, and the electromagnetic intensity maximum at this time reaching is convenient to honeywell switch sensor and is detected. Minimum distance≤the 5mm of the left-hand face of the right side of described magnet 3 and isolated pipe 2, this is convenient to electromagnetic induction within the specific limits apart from controlling.
