The invention discloses a petroleum drilling machine system energy-saving control method based on self-adaptive PID, and relates to the technical field of petroleum drilling machine energy-saving control, and the method comprises the steps: selecting a target reference track from an energy consumption map according to a drilling working condition, and generating a multi-dimensional deviation signal; the signal is separated into a low-frequency trend component reflecting a rigid load and a multi-frequency oscillation component reflecting dynamic disturbance by using a characteristic decomposition network. And according to the time domain energy ratio of the two components, decoupling independent calibration is carried out on proportion, integral and differential parameters of the PID controller. And based on the calibrated parameters, a drilling pump power compensation instruction generator and a winch motor rotating speed compensation instruction generator are driven in parallel. And the two outputs are fused to generate a comprehensive regulation control quantity which is synchronously applied to a drilling pump and a winch motor. By means of the method, fine decoupling and targeted control over the load characteristics of the drilling machine are achieved, and the dynamic response quality and the overall energy efficiency of the system under the complex working condition are improved.

The application discloses a wave compensation drilling winch device and belongs to the technical field of marine drilling equipment. The device comprises a winch body, a monitoring unit and a control unit. The winch body comprises a first support, a drum, a steel wire rope, a first driving device and a safety protection device. The free end of the steel wire rope is connected with a dead rope fixer fixed on a derrick after winding through a fixed pulley on a drilling tower crane and a movable pulley on a travelling block. A drill string is connected with the travelling block. The monitoring unit comprises a weight indicator. The control unit is used for calculating an actual drilling pressure value of the drill string according to a detection value of the weight indicator. The control unit can compare the actual drilling pressure value with a set drilling pressure value, and adjust the rotation direction and / or rotation speed of the drum to make the actual drilling pressure value equal to the set drilling pressure value according to a comparison result by controlling the first driving device. The application effectively improves the wave compensation effect, guarantees the smooth drilling operation and has a good application prospect.

The invention discloses an automatic treatment system for a pipe column of a three-joint unit parallel high-position connecting and throwing three-joint unit drilling machine. The system comprises a power catwalk arranged right in front of a drilling machine base, a derrick is arranged on a drilling platform, a top drive is installed on the derrick, and a drilling platform manipulator is installed on the drilling platform; a racking platform is arranged on the derrick, the front end of the racking platform is of an opening structure, and a racking platform mechanical arm is installed on the racking platform. A drill floor winch is arranged on the drill floor face of the drilling machine and connected with the three-joint unit through a steel wire rope. The invention further discloses an automatic treatment method for the pipe column of the stand parallel high-position connecting and throwing stand drilling machine, stand connecting and stand discharging from a well mouth to a racking platform finger board area can be achieved, and drilling throwing from the stand within the well mouth range or from a single stand to a catwalk can be achieved; in addition, in the drilling process of the drilling machine, drilling and off-line receiving of a three-joint unit array sent from a catwalk ramp or three-joint unit throwing operation directly from a racking platform to the ramp can be achieved at the same time. According to the two-way three-joint operation mode, the working efficiency of the petroleum drilling machine is effectively improved.

The invention relates to the technical field of petroleum drilling machine winch maintenance, in particular to a drilling machine winch steel wire rope arranging method which comprises the following steps that firstly, impurities on the surface of a winch rope barrel are cleaned up; during operation, the first end of the new steel wire rope is wound on the outer side of the winch rope barrel by a circle and then fixed to the outer side of the winch rope barrel, then the tensioner and the hoisting assembly are installed, and after the hoisting equipment hoists the new steel wire rope through the hoisting assembly and the tensioner, the clamping force of the tensioner on the new steel wire rope is adjusted to an initial set value; in this way, after the winch rope barrel is started, the clamping force between the inner wall of the tensioner and the new steel wire rope is adjusted according to the swing amplitude and the swing direction of the tensioner, so that the clamping force between the inner wall of the tensioner and the new steel wire rope ensures that the new steel wire rope is in a tensioned state in the winding process. Therefore, the new steel wire rope is neatly, tightly and quickly wound on the outer side of the winch rope barrel, operation cost is reduced, and operation safety is guaranteed.

The utility model provides a low-gravity-center automatic off-line drilling machine which solves the problem that the overall gravity center of equipment is moved upwards and the overall stability of a derrick is affected due to the fact that core equipment for hoisting a drilling rod is integrated on the top of the derrick. According to the lifting system, the winch and the driving device in the lifting system are arranged at the bottom of the derrick, so that the weight of the top end of the derrick can be reduced, the gravity center of the derrick can be lowered, the overall stability of the derrick can be improved, and the risk that the derrick inclines or even overturns can be reduced; and the sling can upwards bypass the first pulley and downwards connect with the crown block to lift the crown block.

A dual line drawworks system and methods of using the same. A drilling rig may include two drawworks, each attached to a drilling line that extends through a series of sheaves located on the crown block and a traveling block. One end of the drilling line may be attached to an anchor. The traveling blocks may comprise a series of split blocks which may be separately movable from one another and may be removably attached to an underside of the crown block. The two drawworks may be coupled to one another and to one or more control systems, which may include one or more variable frequency drives, and the two drawworks may be configured to operate at the same speed. Systems may be used to monitor the distance between the traveling blocks and detect and correct for any excess distances therebetween.
