    In a hydraulically powered pipe handling system, a general purpose digital computer is used to control the operation of hydraulically powered racker arms as well as the various auxiliary functions involved in vertical piperacking operations. The manual pipe-racking system (that is, that which is hydraulically powered and under the control of one or more operators) is retained, the computer controlled mode of operation being an alternative system present in the overall design.

    专利说明:

    The invention relates to automated drilling rigs, namely, devices for lowering and lifting a drilling tool in the process of drilling a well (the process of extracting a drilling string and placing candles on the rig proceeds in automatic mode).
    Closest to the invention is a device comprising a stand for receiving and storing spark plugs of drill pipes, a rack mechanism, lifting and clamping heads, a finger of a stack arranged in parallel rows of Cl.
    However, this device does not allow launching operations in automatic mode.
    The aim of the invention is to provide automation of the process,
    This goal is achieved by the fact that the device is equipped with a control computing unit, a unit for input and output, a unit for reproducing and indicating, and a drill console with a mode selector, while the rack mechanism has a lifting head with a horizontal lever, a carriage support unit and state sensors a lifting head for clamping the pipes and opening the fingers; and a speed sensor of the rack and pinion mechanism associated with the computing unit.
    In addition, the device is equipped with an additional rack and pinion mechanism with a carriage, gripping candles of drill pipes, a carriage support unit and a sensor to clamp the plugs.
    Figure 1 shows the drilling tower, a vertical section; in Fig. 2, the rack unit and guide finger panels, top view; on fig.Z lifting head; figure 4 - pliers lifting head; in fig. 5, b and 7 - types of the rack mechanism with sensors; 8 — units of a computing unit; figure 9 - panel starting block; figure 10 - lift pipes; figure 11 shows the algorithm for raising the drilling tool from the well.
    Rack mechanisms 1, 2 and 3 are placed on the rig (Fig. 1), which are used to install candles on the tower rack, which has guide fingers 4 with clips 5 and b (). Each guide pin 4 has a series of dispersed constipations spaced apart from each other at a distance sufficiently large enough to accommodate the diameter of the drill pipe and extending from one to the other end of the guide pins. In this case, 12 such locks are shown for each guide finger. Open or raised
    The positions of the locks are shown, for example, by the position 6, and in the closed positions by the position 5. With the lock open, the pipe can freely move between and between the guide pins.
    Fig. 2 shows a carriage support assembly 7, a gripper of 8 pipes disposed on a lever 9, a carriage 10 with a reversing engine 11; in FIG. 3 a lifting head with pliers 12 and a lifting cable 13; Fig. 4 illustrates the operation of ticks controlled by hydraulic cylinders 14 and 15.
    Figs 3b and 7 show the placement of the engine 11 of the carriage and the sensor 16 of the speed and position of the rack and pinion mechanism.
    On Fig shows the block 17 of the display, the computing unit 18 and the remote control 19 driller, as well as input and output signals to the computing unit. FIG. 10 shows a lift 20 (see also FIG. 1b having a rigid locking sensor 21 of the lift. A candle 22 of drill pipes is clamped by pliers, horizontal levers of rack and pinion mechanisms 1 and 3.
    Figure 11 shows the algorithm for lifting the drilling tool in the form of a sequence of operations: 22-33 separate operations.
    In addition, the device contains a winch 34 with a cable 35 and a pulley 36, a tong of a 37-top rack mechanism.
    9 The device operates as follows.
    The boring tool is removed from the well in the usual way with the help of a winch 34 with a lift 20 and a cable 35 of the polyspast 36. After the top candle is disconnected from the drill pipes, the candle is clamped and lifted with the help of the pinion mechanisms 1 and 3 and the cable 13 of the head 12. The carriage movements and locking of the lift are fixed respectively, the sensors 16 and 21 are electrically connected with the computing unit 18, to which, in turn, signals from the console 19 can be supplied using control nodes, as shown in Fig. 9. The output of block 18 is connected to the display block 17, which displays the progress of operations. The obtained computational block 18 sensors signals are analyzed and then, in accordance with the program laid down, block 18 acts on the rack mechanisms 1 and 3 and installs a candle on stella x.
    FIG. Figure 11 illustrates the progress of operations when lifting a drilling tool from a square. When the device is operating, block 23 indicates that the rack mechanisms shown in FIG. positions 1 and 3 are in a standby position away from the axial line of the well (between the axial line of the well and the wall of the drill). In preparation for lifting the drill string, manual work is first performed, in which the operator is required to raise the hauling block and the string of the drill pipe and set it so as to secure the drill string in place and prevent further vertical movement. This position, the drill string, is illustrated in Fig. 1, where the chain hoist unit is lifted by applying a lifting mechanism 34. and a cable 35. As shown by block 25; two rail gears move to the centerline of the well, and their tongs capture the drill pipe attack. At this moment (as shown by block 26 |, an additional manual action is performed, i.e. the connection is disconnected by manual or automatic actuation of the grippers (not shown). In addition, the elevator 20 opens and the polyspast block 36 pulls away to the wall oil rig 1FIG.1) to allow the rack to move away from its location adjacent to the axial
    SKVEZHINY lines ..
    As shown in block # 27, the automatic operation of the drill pipe placement system on the rack is selected again, with which the lifting head 12, actuated through the cable 13, lifts the stand vertically in order to release the end of the drill string. Block 28 illustrates the following automatic action, by which pee ltnte mechanisms 1 and 3 are simultaneously transferred to a location adjacent to the guide finger panel (Fig. 2). Further, as shown by block 29, mechanism 1 and 3 are synchronously translated to the column location in one of the spaces of the guide pin panel. Block 30 shows that lifting head 12 automatically lowers the rack to the installation site. Block 31 shows that the corresponding latch of the guide pin 5 (locks the stand in place within the guide pin panel. Block 32 shows that the pincers 12 and 37 open and release the stand, and the pinion mechanisms 1 and 3 return to the standby position at some middle the point between the wall of the drilling rigs and the axial line of the well, as shown by block 33.
    The program logic of the computing device allows for effective flexibility in providing the required displacement of the levers of the rack and pinion mechanism, which performs oblique storage of pipes. In case oblique storage of the pipe is required, the upper 1 and middle 3, and possibly the lower 2, the rack mechanisms for placing the pipe on the rack are programmed to cause tilting curved sections of the pipe during the initial phase of movement along the vertical axis, after which the rack and pinion mechanisms will transport the sections tr Decreased in inclined position to their specific location; praised ..
