Abstract
Ther utility model discloses a sliding bush type pin-break mechanism for a drilling clinometer, which is a pin-break mechanism on an impact type siphon device used for automatically measuring inclination of boreholes for drilling crew in oil fields. The original pin-break mechanism is a discrete part structure, an inner cylinder repeatedly crashes in an outer cylinder after the inclinometer shears pin; thus, a pressure spring is impacted and damaged, and the midway detection during the drilling is influenced. The utility model is an improvement on the basis of the existing mechanism, which is composed of a sliding bush cap, a sliding bush, a connecting seat and a flushing valve which are arranged in the sliding bush, etc. The utility model has the functions of spacing, righting, buffering and anti-shedding, and increases the measuring success rate of the clinometer.
Description
It is that oil drilling team measures the mechanism that cuts off on the impact type syphon inclinometer that the well gradient uses voluntarily that the sleeve type of well drilling slope level cuts off mechanism.This mechanism finishes the key position of measuring hole deviation, cuts off whether finishing of action, is directly connected to the success or failure of measurement.
The mechanism that cuts off in the used impact type syphon inclinometer is made up of four parts such as drift, pin, red seat, holddown springs, because this mechanism is the loose mail structure, and inclinometer is when cutting off, after impact force is cut off pin, inner core is because the effect of impact force, in urceolus, collide repeatedly up and down, cause the red seat that cuts off in the mechanism, holddown spring, cut off the back and break away from drift, uncontrolledly punching press damage in tube, there is damage in various degree in capital of every measurement, directly influences the detection midway of drilling quality.
The purpose of this utility model is to solve the fragile problem that present syphon inclinometer cuts off mechanism, for this instrument provides a kind of integrally-built sleeve type punching mechanism.
Description of drawings: Fig. 1 is the structural representation that the sleeve type of well drilling slope level cuts off mechanism, and (1) sliding sleeve top cover, (2) sliding sleeve, (3) connect cover for seat, (7) valve spring, (8) valve bar towards valve, (4) pin, (5) holddown spring, (6) among the figure.
Below in conjunction with accompanying drawing the utility model is described in detail:
The mechanism that cuts off of existing inclinometer is made up of drift, pin, red seat, connection cover for seat etc.The utility model improves on existing basis.It is by sliding sleeve top cover (1), sliding sleeve (2) and be set in the connection cover for seat (6) in the sliding sleeve (2) and form towards valve (3).Sliding sleeve top cover (1) connects with sliding sleeve (2) by screw thread, has four pin-and-holes at the middle part of sliding sleeve (2), and pin-and-hole connects with interting by pin (4) towards the pin of valve (3), should be provided with spacing spacing between valve (3) and sliding sleeve top cover (1).
After the impact type syphon inclinometer drops into drilling tool bump drill bit, inner core is under effect of inertia, lower springs is compressed, spring is upspring inner core when releasing energy, make inner core top cut off sliding sleeve top cover (1) the bump urceolus top of mechanism, its impact energy is cut off pin (4) by sliding sleeve (2), holddown spring (5) releases energy simultaneously and will upspring towards valve (3), at this moment, the valve spring (7) that connects in the cover for seat (6) lifts valve bar (8) simultaneously, valve is opened the back ink and is entered record cylinder, the beginning surveying work.
The sleeve type of well drilling slope level cut off mechanism have spacing, set upright, the function of buffering, slip-off preventing.The utility model has improved existing application life and reliable sensitivity with the deviational survey instrument, and can improve the success rate of measurement, to measuring wellbore quality timely and accurately, guarantees the workmanship of drilling well, has great function.
Claims (2)
1, a kind of sleeve type that is used for well drilling slope level cuts off mechanism, it is by drift, pin, red seat, connect compositions such as cover for seat, feature of the present utility model is that sleeve type cuts off mechanism by sliding sleeve top cover (1) sliding sleeve (2) be set in the connection cover for seat (6) in the sliding sleeve (2) and formed towards valve (3), sliding sleeve top cover (1) connects with sliding sleeve (2) by screw thread, have four pin-and-holes at the middle part of sliding sleeve (2), pin-and-hole connects with interting by pin (4) towards the pin-and-hole of valve (3).
2, sleeve type according to claim 1 cuts off mechanism, it is characterized in that cutting off dashing between valve (3) and the sliding sleeve top cover (1) of mechanism at sleeve type should be provided with spacing spacing.
