Background technology
Need to be at well head to measuring with the angular deviation (angular difference) of boring between the curved side's sign of instrument positioning key and screw rod before directional well construction.At present, field by using is that directed personnel carry out hand dipping at rig floor well head.Utilize a fine rule with little iron block to project to the curved side of screw rod and to indicate on an identical horizontal plane with brill instrument positioning key, the distance of measuring is between the two converted into angle again.But, hand dipping needs at least two personnel jointly to complete conventionally, and needing multi-pass operation just can complete with boring instrument positioning key and the curved side's tag distance of screw rod when far away, while having the larger centralizer of external diameter between positioning key and curved side sign, hand dipping difficulty and precision are not high, and it is just more difficult that the bad weathers such as blowing and raining complete surveying work.Hand dipping also easily causes larger error.
Utility model content
The utility model is intended to address the above problem, and in order to improve certainty of measurement, saves Measuring Time and overcomes bad weather impact, a kind of measuring instrument is provided, this instrument can not only Measurement accuracy angular difference, and can improve certainty of measurement, saves Measuring Time and is not subject to weather effect.Its technical scheme adopting is as follows:
Novel Directional Well bicker difference measuring instrument, it is characterized in that: comprise dog screw, laser pen, laser pen stand, half ring seat, nut, pointer slide, pointer, clip legs, slideway pin, torsion spring, dial pin, dial, bolt, rotary spanner, bolt push rod, annulus nut, tegillum, described dog screw is connected with half ring seat by screw thread, described laser pen is sitting on laser pen stand by hole, described laser pen stand is connected with half ring seat by rectangle chute, described nut and bolt are threaded connection, described pointer slide is connected with dial by slideway, described pointer is connected with pointer slide by hole, described clip legs connects into the clip mechanism with tensile force by torsion spring and slideway pin, described dial pin is connected with dial, described rotary spanner coordinates by hexagon with annulus nut, described tegillum is connected with half ring seat.
Above-mentioned lock screw can be carried out tensioning location to laser pen stand according to the radius size of surveyed cylinder, guarantees that the laser energy of laser pen transmitting arrives dial.
Above-mentioned dial is to be linked together by pin by two semi-rings, can carry out freely opening, and forms discoid during measurement, be convenient to measure, meanwhile, dial pin can carry out radial motion at slideway pin, while guaranteeing to measure, dial is concentric with tested cylinder, guarantees certainty of measurement.
Above-mentioned clip is used for holding tightly tested cylinder, and the support force of dial is provided.Pointer can carry out motion radially, and slide can carry out circumferential motion on dial simultaneously, and assurance pointer can point to by lateral bending side and indicate, is convenient to reading out data, raises the efficiency and precision.
Above-mentioned rotary spanner rotation coordinates principle by nut bolt, make bolt push rod can carry out radial motion, half ring seat has a location fritter over against the position of laser pen stand, while using measuring instrument, allow location fritter and tested keyway be stuck, then rotary spanner makes half ring seat compress tested cylinder, and the object of using is like this that laser pen is on the line in keyway and the cylinder center of circle, guarantees certainty of measurement.
Beneficial effect: Directional Well bicker difference measuring instrument can be simplified the step of hand dipping angular difference, once completes angular difference and measures, and measuring process and precision are not subject to the weather effects such as blowing and raining, utilize laser to make measurement result very accurate, simple in structure.
