Description
Предлагаемый, согласно изобретению , прибор предназначен дл ориентировани ствола скважин направленного турбинного бурени . Прибор состоит из буссоли, указател наклона и указател плоскости искривлени трубы, с помощью которой задаетс необходимое направление турбобуру.The device according to the invention is intended for orienting a wellbore of directional turbine drilling. The device consists of a compass, an inclination indicator and an indicator of the plane of curvature of the pipe, with the help of which the required direction of the turbodrill is set.
Буссоль и указатель наклона служат дл определени положени в пространстве оси турбобура, т. е, элементов кривизны скважины в интервале расположени последнего.The compass and the tilt indicator serve to determine the spatial position of the axis of the turbo-drill, i.e., the curvature elements of the well in the interval where the latter is located.
Указатель плоскости искривлени трубы служит дл определени направлени действи искривл ющих усилий трубы.The index of the curvature plane of the pipe serves to determine the direction of the curvature of the pipe.
Измерени всех вышеуказанных парамеров производ тс в бурильных трубах, дл чего выще турбобура на 10-15 метров устанавливаетс отрезок бурильной трубы из немагнитного материала.Measurements of all the above parameters are carried out in the drill pipe, for which purpose a turbo-drill for 10-15 meters is established a segment of the drill pipe from a non-magnetic material.
Опуска прибор в скважину под напр жением и наблюда по амперметру величину силы тока, можно с достаточной точностью зафиксировать момент достижени прибором интервала, в котором необходимо произвести соответствующие измерени .When the device was lowered into the well under voltage and the magnitude of the current was observed by an ammeter, it is possible to record with sufficient accuracy the moment the device reaches the interval in which the corresponding measurements need to be made.
Предлагаемый прибор позвол ет без спуска и подъема бурового инструмента контролировать направление ствола бур щейс скважины.The proposed device allows, without lowering and lifting a drilling tool, to control the direction of a wellbore.
Вместо поочередного инклинометрировани скважин и последующего определени положени плоскости искривлени кривой трубы производитс всего лищь одна операци .Instead of alternating the inclination of the wells and the subsequent determination of the position of the curvature plane of the pipe’s curve, the entire procedure is performed.
Небольшое количество времени, необходимое на производство одного замера, позволит значительно увеличить густоту наблюдений.A small amount of time required to produce a single measurement will significantly increase the density of observations.
Непосредственное определение ориентировани кривой трубы устран ет ошибки, возникающие из-за закручивани бурильных труб при повороте кривой трубы ротором.Directly determining the orientation of the curve of the pipe eliminates errors due to the twisting of the drill pipes when the curve of the pipe is rotated.
