Description

(54) УСТРОЙСТВО ДЛЯ И314ЕРЕНИЯ. ГЛУБИНЫ СКВАЖИНЫ(54) DEVICE FOR I314ENII. DEPTH WELLS

II

Изобретение относитс  к нефт ной и газовой промышленности, в частности , к устройствам контрол  процессов бурени  нефт ных и газовых скважин .The invention relates to the oil and gas industry, in particular, to devices for controlling the processes of drilling oil and gas wells.

Известно устройство измерени  проходки скважины, состо щее из датчика подачи инструмента, установленного на кронблоке, счетчиков импульсов , блока логики. Измерение проходки ,в этом устройстве основано на измерений перемещени  верхнего конца бурильных труб, т,е, на измерении подачи Til.A well penetration measurement device is known, consisting of a tool feed sensor installed on the crown block, pulse counters, a logic unit. The measurement of penetration, in this device is based on measurements of the movement of the upper end of the drill pipe, t, e, on the measurement of feed Til.

Одрако данное устройство не обеспечивает контроль положени  доло- . та во врем  спуско-подъемных операций , который приобретает первострпенное значение при ликвидации аварий , вызванных поломками инструмента . Кроме того, устройство имеет низкую точность измерени  глубины забо  из-за отключени  датчиков наOdrako this device does not provide control of the position of the dolo-. that during tripping, which is of paramount importance in the elimination of accidents caused by instrument failures. In addition, the device has a low accuracy of measurement of the bottomhole depth due to the disconnection of sensors on

врем  спуско-подъемных операций и наращивани  инструмента.time of tripping and tool buildup.

Известно также устройство дл  измерени  глубины скважины в процессе бурени , содержащее датчик оборотов лебедки, датчик веса на крюке , блок логики, блок счетчиков и блок коррекции, контролирующее перемещение инструмента по количеству оборотов барабана лебедки с компен10 сацией погрешностей, возникающих при смене слоев каната 2.It is also known a device for measuring the well depth during drilling, comprising a winch speed sensor, hook weight sensor, logic unit, counter block and correction unit controlling the tool movement by the number of revolutions of the winch drum with compensation for errors occurring when changing the layers of the rope 2.

Недостатком этого устройства  вл етс  низка  точность контрол  положени  долота в скважине и глубины A disadvantage of this device is the low accuracy of control of the bit position in the well and depth

15 забо  ввиду изменчивости характера навивки талевого каната на барабан лебедки.15 in view of the variability of the nature of the winding of the rope rope on the winch drum.

Наиболее близким по-технической, сущности к предлагаемому  вл етс  The closest to the technical, the essence of the proposed is
