Изобретение относитс к горным работам и может быть использовано дл повьниени точности бурени направленных скважин.The invention relates to mining and can be used to improve the accuracy of drilling directional wells.
Известен способ контрол за направлением бурени , основанный на определении местонахождени генератора-прибора, опущенного в скважину до уровн бурового инструмента 1.There is a known method of controlling the direction of drilling, based on determining the location of the generator instrument, lowered into the well to the level of the drilling tool 1.
Недостатком этого способа вл етс необходимость фиксации местонахождени прибора только в одной точке пробуренного пространства скважины, что не позвол ет быстро и своевременно ориентировать буровой инструмент в заданном направлении.The disadvantage of this method is the need to fix the location of the device only at one point in the drilled space of the well, which does not allow for quick and timely orientation of the drilling tool in a given direction.
Известен способ контрол за направлением бурени скважины, основанный на использовании вспомогательных скважин, включающий регистрацию пространственных координат вспомогательных скважин по их глубине и определение местонахождени забо бур щейс скважины путем излучени и регистрации упругих волн с помощью излучателей и приемников колебаний 2.A known method of controlling the direction of drilling a well is based on the use of auxiliary wells, which includes recording the spatial coordinates of the auxiliary wells by their depth and determining the location of the bottom of the drilling hole by emitting and registering elastic waves using emitters and oscillation receivers 2.
Недостатком этого способа вл етс необходимость фиксации приемного устройства на определенной высоте у забо скважины, вследствие чего упругие волны распростран ютс в различных напластовани х пород, что снижает точность бурени основной скважины.The disadvantage of this method is the necessity of fixing the receiving device at a certain height at the bottom of the well, as a result of which elastic waves propagate in different layers of rocks, which reduces the accuracy of the drilling of the main well.
Цель изобретени - повыщение точности контрол направлени бурени . 5Эта цель достигаетс тем, что в процессеThe purpose of the invention is to increase the accuracy of controlling the direction of drilling. 5This goal is achieved by
бурени скважины осуществл ют непрерывный спуск во вспомогательных скважинах излучателей и приемников синхронно с движением бурового инструмента.the boreholes carry out continuous descent in auxiliary wells of emitters and receivers synchronously with the movement of the drilling tool.
На чертеже приведена схема, по сн ю0 ща предлагаемый способ.The drawing shows a diagram, as described below, the proposed method.
Предварительно до начала работ по бурению основной скважины 1 бур т вспомогательную скважину 2 малого диаметра на рассто нии семи и более метров. При выборе рассто ни между скважинами 1 и 2 учитывают характеристику примен емой аппаратуры 3, создающие упругие волновые пол и измер ющей их на глубинах. В предварительно заранее пробуренную структурную, гидронаблюдательную, замораживающую 20 и т. п. скважину опускают аппаратуру 3, создающую и измер ющую упругие волновые пол , например серийную аппаратуру, используемую при определении координат забо скважин геоакустическим методом.Before starting work on drilling the main well 1, an auxiliary well 2 of small diameter is drilled at a distance of seven meters or more. When choosing the distance between wells 1 and 2, they take into account the characteristics of the equipment used 3, which create elastic wave fields and measure them at depths. Into a preliminarily drilled structural, hydro-observation, freezing 20, etc. well, equipment 3 is lowered, which creates and measures elastic wave fields, for example, serial equipment used to determine the coordinates of the bottom hole by geoacoustic method.
