Abstract
The invention discloses a detection method of the sealing property of a valve head and a valve seat of a wireless inclinometer while drilling, and relates to the technical field of drilling tools. The detection method comprises the following steps: screwing a one-way air inlet valve on a lifting rod of a pulser of the wireless inclinometer while drilling; connecting an inflator to the one-way air valve; inflating into the pulser through the inflator; observing whether gas flows out on an overlapped part of the valve head and the valve seat so as to realize test of the sealing property of the valve head and the valve seat of the pulser. According to the detection method of the sealing property of the valve head and the valve seat of the wireless inclinometer while drilling, the sealing property can be tested after the pulser is assembled and the travel of the valve head and the coaxiality with the valve seat are adjusted, and the sealing property of the valve head and the valve seat of the pulser can also be tested on site; the testing method is easy to operate; the testing tool is convenient to carry; once the instrument fails on the site, the problem of the instrument can be timely troubleshot by using the equipment; the instrument is not required to be turned to the factory; the detection cost is reduced; the problem examination time is saved.
Description
Technical field
The present invention relates to drilling tool technical field, be specifically related to a kind of wireless drilling inclinometers valve head valve base sealing detection method.
Background technology
In petroleum drilling engineering, directed drilling application is more and more extensive, and wireless drilling inclinometers (hereinafter to be referred as MWD) is the important tool of carrying out directed drilling, because of its stable performance, the high demand of this quasi-instrument that makes of reliability increasing.At present MWD is after instrument pulser has been assembled and regulated by the stroke of valve head and with the axiality of valve seat, valve head is overlapped with two fillet surfaces of valve seat, thereby reach theoretical sealing effectiveness, but whether cannot detect the real sealing effectiveness that reached; While using at the scene, also cannot the valve head of paired pulses device and the sealing of valve seat test, thereby cannot judge accurately whether pulser can also reach instructions for use, can cause very large impact to the work accuracy of MWD like this.
Summary of the invention
The invention provides a kind of wireless drilling inclinometers valve head valve base sealing detection method, with after solving the pulser of the MWD that prior art exists and having assembled, cannot the valve head of paired pulses device and the sealing of the valve seat problem of testing.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of wireless drilling inclinometers valve head valve base sealing detection method, first a breather cheek valve is screwed in above the lifting arm of wireless drilling inclinometers pulser, inflator is connected to above Non-return air valve, by inflator, toward pulser the inside, suppress, whether have gas flow out, thereby realize the valve head of paired pulses device and the performing leak test of valve seat if observing valve head and valve seat overlapping position.
Wireless drilling inclinometers valve head valve base sealing detection method of the present invention, both can be after pulser have been assembled and by the stroke of valve head and with the axiality of valve seat, regulated after carry out performing leak test, also the valve head of paired pulses device and the sealing of valve seat are tested at the scene; Especially when maintenance and fault eliminating, more can embody his superiority, method of testing of the present invention is simple to operate, testing tool is easy to carry, once breaking down at the scene, instrument can investigate timely instrument existing problems with this equipment, do not need to return factory, reduce the cost detecting, saved the time of inspection problem.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is the detection schematic diagram of wireless drilling inclinometers valve head valve base sealing of the present invention.
The specific embodiment
As shown in the figure, a kind of wireless drilling inclinometers valve head valve base sealing detection method, both can be after pulser have been assembled and by the stroke of valve head and with the axiality of valve seat, regulated after paired pulses device carry out performing leak test, also the valve head of paired pulses device and the sealing of valve seat are tested at the scene, concrete grammar is as follows: first a breather cheek valve is screwed in above the lifting arm of wireless drilling inclinometers pulser, inflator is connected to above Non-return air valve, by inflator, toward pulser the inside, suppress, whether observe valve head and valve seat overlapping position has gas to flow out, thereby realize the valve head of paired pulses device and the performing leak test of valve seat.
Claims (1)
1. a wireless drilling inclinometers valve head valve base sealing detection method, it is characterized in that first a breather cheek valve being screwed in above the lifting arm of wireless drilling inclinometers pulser, inflator is connected to above Non-return air valve, by inflator, toward pulser the inside, suppress, whether have gas flow out, thereby realize the valve head of paired pulses device and the performing leak test of valve seat if observing valve head and valve seat overlapping position.
