Abstract
The invention discloses a petroleum drilling machine control device comprising a load sensor; the load sensor is arranged on a fixed end of a winch rope and used for measuring drilling pressure of a hook block assembly and a drilling tool; the load sensor is connected with a controller; the controller is connected with a control valve; the controller calculates and processes a detected load signal V2, a set speed signal V3 given by the control valve, and a drilling pressure reference signal V4 set by the controller, thus outputting a control signal V5; a signal converter is used to control an execution mechanism, thus controlling brake force of the winch; a winch roller is provided with a signal emitter used for detecting a winch rotating speed signal; the signal emitter inputs the detected winch roller rotating speed signal V1 into the controller. The petroleum drilling machine control device allows driller operations to be easy, thus reducing driller work intensity, improving driller work environment, improving driller work safety and personal safety, and improving petroleum drilling machine automation control level.
Description
Technical field
The present invention relates to a kind of oil-well rig control device.
Background technology
The traveling system of general oil-well rig is all handle winch brake lever by driller to control the lowering velocity of hook block and the pressure of the drill of downhole drill bit, and driller's work is very arduous, and working environment is very severe.
Summary of the invention
For solving above-mentioned existing shortcoming, main purpose of the present invention is the oil-well rig control device providing a kind of practicality, by realize driller to oil-well rig move about the lowering velocity of system and downhole drill bit the pressure of the drill far distance controlled and arbitrarily control, thus reach that driller is operated is free and relaxed, alleviate the labour intensity of driller, improve the working environment of driller, improve work safety and the personal safety of rig, and improve the automatic control level of oil-well rig simultaneously.
For reaching above-described object, following technical scheme taked by a kind of oil-well rig control device of the present invention:
A kind of oil-well rig control device, comprise the load transducer for measuring hook block and drilling tool the pressure of the drill size being installed on winch rope fixed end, it is characterized in that, described load transducer is connected with controller, described controller is connected with control valve, the load signal V that controller will detect
2with the set speed signal V that control valve provides
3, and the pressure of the drill reference signal V of controller setting
4a control signal V is exported after carrying out computing
5, then go to control executing agency by signal adapter, realize the brake weight size controlling winch, described winch drum is equipped with the sender unit detecting winch tach signal, the winch drum tach signal V that described sender unit will detect
1be input in controller.
Adopt the present invention of as above technical scheme, there is following beneficial effect:
The rate signal of 1, Bian collection being returned by controller and the rate signal of load signal and setting and the pressure of the drill signal, a control signal is exported after carrying out computing by computer, the variable signal being converted into mechanical force by signal adapter, controlling organization again controls the size of winch brake power, can realize in the process of making a trip hook block at the uniform velocity, constant speed transfers, and can realize the constant voltage automatic bit feed of downhole weight on bit in drilling process.
2, the speed that the lowering velocity of hook sets according to driller is at the uniform velocity transferred, and the numerical value that the pressure of the drill sets according to driller evenly send brill, the pressure of the drill precise control, fluctuates little, and the process that feeds is without impact.
3, safety, reliably, uphill process and decentralization process are controlled by upper anti-collision height and lower anti-collision height respectively, uphill process can not hit overhead traveling crane, decentralization process can not pound rotating disk, when lowering velocity exceedes maximum setting speed, automatically perform snub, and when hook block transfer highly arrive a certain setting height time system automatically can start soft landing function, hook uniform speed slow is transferred, when hook block arrives rotating disk, speed is kept to zero gradually, ensure that the safety of oil-well rig, in drilling process, as down-hole formation hardness changes suddenly, can prevent drill string from hurtling down, big and heavy stone is avoided to bore and drilling string not well braked, as emergency, " stopping dead " state of can guaranteeing that winch can be in.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the schematic diagram of controller of the present invention.
Detailed description of the invention
In order to further illustrate the present invention, be described further below in conjunction with accompanying drawing:
As depicted in figs. 1 and 2, a kind of oil-well rig control device of the present invention, comprise the load transducer 1 for measuring hook block and drilling tool the pressure of the drill size being installed on winch rope fixed end, this load transducer 1 is connected with controller 7, controller 7 is connected with control valve 8 simultaneously, the load signal V that controller 7 will detect
2with the set speed signal V that control valve 8 provides
3, and the pressure of the drill reference signal V that controller 7 sets
4a control signal V is exported after carrying out computing
5, then go to control executing agency 5 by signal adapter 6, realize the brake weight size controlling winch 4, winch 4 cylinder is equipped with the sender unit 3 detecting winch tach signal, the winch drum tach signal V that sender unit 3 will detect
1be input in controller 7.Controller is primarily of formations such as comparing unit, detection, conversion, anti-hungry unit, by detecting element, the rate signal recorded and pressure signal are compared as the setting value of actual value and operating grip or the artificial set-point inputted through conversion, show that control signal drives executing agency's work, the controllable silicon producing rational start pulse signal control major loop carries out variable voltage control, reaches the object of control.
Operating principle of the present invention: the sender unit 3 be contained on winch drum shaft detects the tach signal V of winch drum 4
1, the load transducer 1 being contained in traveling system dead line end detects load signal V
2, control valve handle 8 provides set speed signal V
3, controller 7 sets the pressure of the drill reference signal V
4, controller 7 moment detects four kinds of signals.In the process of making a trip, controller 7 couples of V
1, V
2, V
3three kinds of signals carry out computing, are sending in drill-through journey V
1, V
2, V
4three kinds of signals carry out computing, export a kind of control signal V
5, then go to control executing agency 5 by signal adapter 6, realize the brake weight size controlling winch 4, thus control the lowering velocity of hook block and drilling tool 2.The process of the adjustment drum speed of this automatic stepless, thus achieve in the process of making a trip, keep the lowering velocity of hook block to carry out " at the uniform velocity transferring ", sending in drill-through journey, keep " constant voltage send brill " of down-hole equipment.
