Abstract
The utility model relates to a balancing instrument for angle difference measurement of a wireless while-drilling measuring instrument. The balancing instrument is a rectangular solid; a downwards protruding key is arranged at the central position of the bottom of the balancing instrument; the width of the downwards protruding key is matched with a groove on a pulse device of the wireless while-drilling measuring instrument; the center of the upper part of the balancing instrument is provided with a groove and is installed with a bubble level instrument; the protruding key at the bottom is placed in the groove of the pulse device of the while-drilling measuring instrument; and then the angle is adjusted by rotating the pulse device until the bubble level instrument points to the water level position.
Description
Technical field
The utility model relates to a kind of wireless drilling measuring instrument angular difference that is used for oil-gas drilling and measure equilibristat.
Background technology
In oilfield exploitation procedure, directional well, horizontal well have obtained widespread usage, have promoted the fast development of wireless drilling measurer simultaneously.Wireless drilling measurer at first will be proofreaied and correct inner angular difference before going into the well, and promptly the deflection angle of inner inserting tube flash of computing equipment and external pulse device keyway provides tool-face angle accurately for directed engineer.The on-the-spot at present normal mode that adopts manual rotary pulsed device range estimation; Judge that the pulser keyway is towards just going up; It is high edge direction; Then at pulser and measure and to draw a straight line on the rod member between the inserting tube and serve as a mark, measure the circumferential lengths of itself and inserting tube flash again, thereby obtain measuring the deflection angle of inserting tube and pulser keyway through mathematical computations.This method is mainly leaned on human eye observation; It is less to add the upper lever diameter, the last angle of calculating of a deflection is arranged a little and actually will differ bigger, and the result is inaccurate; Aligning tool face data after measuring after instrument is gone into the well are inaccurate; Cause the initial orientation orientation to produce easily, be unfavorable for engineering construction, particularly higher cluster well group the well track required precision than large deviation.
Summary of the invention
The purpose of the utility model is to measure the error effect that produces in the angular difference process for overcoming manual work, provide a kind of simple in structure, easy to operate, be applicable to the equilibristat that wireless drilling measuring instrument angular difference is measured.
The utility model adopts following technical scheme:
Be made up of body and air-bubble level, be provided with an outstanding key below the body, its width and wireless drilling measuring instrument pulser upper groove are complementary, and are provided with groove above the body, the interior horizontal positioned air-bubble level of groove.
Outstanding key and groove all are positioned at the body middle part.
Description of drawings:
Accompanying drawing 1 is a kind of example structure front view of the utility model, and Fig. 2 is the vertical view of Fig. 1.
Among the figure: 1. body 2. is given prominence to key 3. air-bubble levels.
The specific embodiment
Existing knot attaches Fig. 1 and 2 to doing further description with novel in fact.
The utility model is that the wireless drilling measuring instrument is measured angular difference and used aid.Is made up of body 1 and air-bubble level 3, is provided with an outstanding key 2 below the body 1, its width and wireless drilling measuring instrument pulser upper groove are complementary, and are provided with groove above the body 1, interior horizontal positioned bubble 3 level gauges of groove.Outstanding key and groove all are positioned at the body middle part.
Use is: after instrument connects completion; The outstanding key in bottom is put into the pulser groove of wireless drilling measuring instrument; Be designated as horizontal level through rotary pulsed device adjusting angle up to air-bubble level then, confirm the pulser flash, and the position write down in setting-out; Measure and the high sideline of inserting tube between concern, calculate definite angular difference with this.
Claims (2)
1. the equilibristat measured of a wireless drilling measuring instrument angular difference; It is characterized in that forming by body (1) and air-bubble level (3); Be provided with an outstanding key (2) below the body (1); Its width and wireless drilling measuring instrument pulser upper groove are complementary, and body is provided with groove above (1), horizontal positioned air-bubble level (3) in the groove.
