Description
Изобретение относитс к измерительным приборам, пpe нaзнaчeнным дл определени кривизны скважин ее вертикальности при установке обратных отвесов с целью наблюдени за деформацией гидротехнических сооружений .The invention relates to measuring instruments, which are intended to determine the curvature of the wells of its verticality when installing return plummets to monitor the deformation of hydraulic structures.
Известен прибор дл определени вертикальности скважин, содержащий подвешенный на тросе корпус, несущий визирную щель и осветительное приспособление под ней. При этом корпус выполнен в виде закрытого с торцов цилиндра, диаметром, завис щим от. , диаметра. скважины, т.е. выполн ющим также и роль центратора с посто нным диаметром. Визирна щель расположена в центре, верхнего торца цилиндра, осветительное приспособление пo 4eщeно под визирной щелью внутри цилиндра. Питание осветительного приспособлени прин то от посто нного источника тока при помощи электрокабел . Трос дл подвески прибора закреплен к ушкам , прикрепленным к верхнему торцу . прибора 1,A well-known device for determining the verticality of wells contains a body suspended on a cable, carrying a reticle and an illumination device under it. In this case, the body is made in the form of a cylinder closed from the ends, with a diameter depending on. , diameter. wells, i.e. also acting as a centralizer with a constant diameter. The reticle is located in the center of the upper end of the cylinder, the light fixture is located 4 under the reticule slot inside the cylinder. The power supply of the lighting fixture is received from a constant current source using an electric cable. The cable for hanging the device is attached to the lugs attached to the upper end. device 1,
Основным недостатком известного прибора вл етс заклинивание корпуса - .цилиндра в скважине в местах ее искривлени , а также затрудненныйThe main disadvantage of the known device is the jamming of the body - the cylinder in the borehole at the places of its curvature, as well as difficult

На чертеже представлен предлагаемый прибор, общий вид.The drawing shows the proposed device, the overall appearance.
Прибор дл определени вертикальности скважин содержит корпус, выполненный в виде сужающейс вниз верти15 кальной ракы 1, к верхнему торцу ко- . торой, прикреплена горизонтальна , пластина 2. В центре пластины размещена визирна .щель 3, представл нада собой отверстие в пластине 2, перек1ил20 тое красным светофильтром. Под визирной щелью .3 установлено осветительное приспособление 4 с автономным (батарейным ) электропитанием. Дл подвески прибора тросом 5 к раме прикреплены 25 I ролики 6. Дл центрировани прибора в скважине прибор снабжен центратором 7. Прибор ут желен грузом 8.A device for determining the verticality of wells includes a housing, made in the form of a narrowing down vertical crayfish 1, to the upper end of the codec. The second is attached horizontally, plate 2. In the center of the plate there is a sighting 3 slot, which is a hole in plate 2, which is crossed with a red light filter. A lighting fixture 4 with an autonomous (battery) power supply is installed under the sighting slit .3. For suspension of the device with cable 5, 25 I rollers 6 are attached to the frame. To center the device in the well, the device is equipped with a centralizer 7. The device is fitted with a weight 8.
Дл определени кривизны скважины прибор с отрегулированным центрато30 ром опускают в скважину с помощьюTo determine the curvature of the well, a device with an adjusted centralizer is lowered into the well by means of
лебедки и подвесной системы. Над скважиной устанавливают тесдолит, который центрируют по центру усть скважины . Кривизну скважины определ ют путем определени координат оси скважины на заданной глубине относительно центра ею усть . Измер ют угол, образованный отвесн.ой линией, проход щей через центр усть скважины, и направлением на визирную щель на заданной глубине. По измеренному углу и рассто нию до визирной щели определ ют величину отклонени центра скважины на заданной глубине от вертикали .winch and suspension system. Tesdolite is installed above the well, which is centered in the center of the wellhead. The curvature of the well is determined by determining the coordinates of the axis of the well at a given depth relative to the center of its wellhead. The angle formed by a plumb line passing through the center of the wellhead and the direction to the sighting gap at a given depth is measured. The measured angle and distance to the sighting gap determine the deviation of the center of the well at a predetermined depth from the vertical.
