Description

При бурении скважин весьма важным  вл етс  правильное по вертикали направление скважины. Искривление ее или влечет за собой необходимость немедленного исправлени , что св зано с дополнительными расходами и увеличивает срок готовности скважины, или приводит к тому, что исправить скважину уже нельз  и ее приходитс  забрасывать.When drilling wells, the correct vertical direction of the well is very important. The curvature of it either entails the need for immediate correction, which is associated with additional costs and increases the time of completion of the well, or leads to the fact that it is already impossible to correct the well and it is necessary to throw it.

Дл  непрерывного измерени  искривлени  буровых скважин уже известны приборы, выполненные в виде опускаемой в скважину камеры, в которой установлены источник света и освещаемые им фотоэлементы, включенные в цепь электроизмерительного прибора. В указанных известных приборах дл  затемнени  фотоэлементов, в зависимости от искривлени  скважины , применена укрепленна  на подвеске заслонка.For continuous measurement of the borehole curvature, devices already known as a camera lowered into the well are already known, in which a light source and illuminated photocells embedded in an electrical measuring instrument are installed. In these known devices for darkening photocells, depending on the curvature of the well, a damper-mounted damper is used.

В предлагаемом приборе, относ щемс  к типу вышеуказанных известных приборов, дл  освещени  фотоэлементов в зависимости от кривизны скважины, источник света подвешен на карданном подвесе.In the proposed device, related to the type of the above known devices, for illuminating the photocells depending on the curvature of the well, the light source is suspended on a gimbal suspension.

Дл  определени  азимута искривлени  скважины по положению световых п тен на фотоэлементах последние выполнены в виде образующих одну плоскую фигуру секторообразных пластин , кажда  пара которых, расположенна  противоположно друг другу, включена в цепь отдельного электроизмерительного прибора.In order to determine the azimuth of the curvature of the well according to the position of the light spots on the photocells, the latter are made in the form of sector-shaped plates forming one flat figure, each pair located opposite to each other is connected to a separate electrical measuring device.

На чертеже фиг. 1 изображает вид предлагаемого прибора в поперечном разрезе и фиг. 2-схему включени  фотоэлементов.In FIG. 1 shows a view of the proposed device in cross section; and FIG. 2 — photocell switching circuit.

Внутри цилиндра А укреплен диск /, удерживающий двум  диаметрально расположенными винтами 2 кольцо 3, которое, в свою очередь, такими же винтами, расположенными по диаметру , поддерживает на весу колпак 4. Таким образом, система подвески колпака 4 представл ет собой карданное сочленение.Inside the cylinder A, a disk / is fastened, which retains two diametrically located screws 2, a ring 3, which, in turn, with the same screws located along its diameter, supports the cap 4 by weight. Thus, the suspension system of the cap 4 is a cardan joint.

Внутри колпака 4 монтирована электрическа  лампа 5 с проводами, выход щими вверх через крыщку 6 прибора . На низ корпуса навинчен колпак 7 с укрепленным в нем молочным стеклом 8. На колпак насаженInside the cap 4, an electric lamp 5 is mounted with wires extending upward through the lid 6 of the device. The cap 7 with the glass of milk fixed in it is screwed on the bottom of the case 8. It is mounted on the cap
