Introduce embodiment of the present utility model with reference to the accompanying drawings:
The multiple spot inclinometer of taking pictures, as shown in drawings, this instrument is to have the geometric properties at the basic principle of fixed directional and plummet and inclination angle and the design of the geometrical relationship between plummet drop point and direction according to magnetic compass.During work, but by the hole deviation inclination angle and the azimuth value of certain time interval continuous measurement well bore different parts, and these parameters are taken on the photographic film of band shape, after the egative film flushing, can read these numerical value by reader.The structure of each assembly of this instrument and mutual alignment are closed to tie up in the implementation and are described in detail.Because this instrument is accurate, therefore must strict control machining accuracy and assembly precision when implementing.For guaranteeing bulk strength and prevent magnetic interference, fishing spear 1, centralizer body 3, active joint 4, extension bar 5, joint 6, outer protection tube 9, joint 13, extension bar 14 and the bumper assembly 15 stainless steel material of handy antimagnetizing are made.The shell in the battery tube 22 of movement assembly 10, sleeve 25, camera darkroom 30, measurement mechanism urceolus 34 and urceolus 42 can adopt aluminum alloy materials to make.Each assembly in camera part and the measurement mechanism must be according to designing requirement strict control machining accuracy and assembly precision, to guarantee the accurate of measurement parameter.When needing to measure the well bore parameter after the finishing drilling or in the drilling process, assemble the movement assembly earlier, adjust interval time of measurement; install each assembly successively by syntagmatic shown in Figure 1,, can adopt heat-proof device for deep-well and high temperature well; movement is packed in the collet, in the outer protection tube of packing into together.Before trip-out the instrument that assembles is dropped in the well, instrument arrives terminal point down within the predetermined time, and this moment, the lower contact 21 of bumper assembly 15 was inserted in the bit port, because lower contact 21 is provided with the flat hole of elongated slot, did not therefore influence the normal circulation of mud.Promptly start working behind the instrument stabilizer, because the axis of instrument body changes with the axis of well bore, and plummet remains vertical, compass remains level and fixed directional, the annular tup of plummet and compass surface forms certain projection relation, and this projection relation is when camera exposes on the band shape film in main lens is photographed the darkroom.Calibration loop 46 in 0～90 ° of angle measuring device remains the plumb position, and U type frame remains the equilbrium position, and graticule and the graduation mark on the calibration loop on the U type frame form certain projection relation, are photographed on the egative film through main lens equally.Intermittently control sheave 33 at the timer of grammed switch 27 controls off and on by drive of motor and drive film movements, can take the hole deviation inclination angle and the azimuth parameter of the variant position of well bore continuously along with the displacement of instrument in the trip-out process.After instrument takes out from well, open protection tube, take out movement, camera and developing tank are put into camera bag together, to open cassette cover and take off film from recycling round and carry out develop, the film after the flushing can be read relevant numerical value by reader.
