Description
Technical field
The present invention relates to a kind of on-the-spot well repairing device and control method of oil and natural gas production field, specifically a kind of intelligent electric drifting device adopting and method.
Background technology
Tractor hoist belongs to the well workover machinery in petroleum recovering equipment, the work such as play lower tubular column, oil well pump, downhole tool while being mainly used in oil-water well operation and salvage.The equipment used of China's workover treatment by land at present mainly contains crawler-type pigging machine, wheeled tractor hoist, workover rig etc.The wherein consumption maximum of crawler-type pigging machine, national recoverable amount approximately has more than 3000 platforms, is mainly used in oil well light maintenance operation.
Oil pipe tripping operation mainly comprises two parts, oil pipe in well is risen to ground or oil pipe is transferred in well.While promoting oil pipe, roller of tractor hoist is rotated in the forward, wire rope drives oil pipe to move upward, in the time connecing hub under oil pipe and exceed well head, cylinder stops the rotation, elevator is placed into well head by the staff of well head, then cylinder reverse rotation, oil pipe decline until next root oil pipe on connect hub and sit on elevator; When lower drain line, cylinder is first rotated in the forward, make to connect hub under oil pipe and exceed well head, the elevator of well head is shifted out well head by the staff of well head, cylinder reverse rotation afterwards, oil pipe starts to enter in well, and then elevator is placed into well head by the staff of well head, and cylinder counter-rotates until connect hub on oil pipe and sit on elevator always.
Tractor hoist is operated by special staff, and staff carrys out rotating and the rotating speed of index drum in tractor hoist control room by pulling relevant action bars.Because derrick is in the middle of tractor hoist and well head, tractor hoist staff must see through derrick and pay close attention to the situation of well head the height of accurate control oil pipe from control room, and slightly carelessness just can cause the accident.When lower drain line, staff must, by repeatedly gathering the method for trying under the staff commander of well head, could contact connecing the upper box cupling of oil pipe in hub and well head under oil pipe.According to the oil production technology in current oil field, the single connection that general R a T is is all 8 meters of left and right by length forms, and in operation, tractor hoist is mentioned or transfers as unit taking single.As can be seen here, must concentrate one's energy for a long time to watch attentively the situation of well head the height of accurate control oil pipe when staff operates tractor hoist, labour intensity is larger, and operating procedure is also more complicated.In the operation with traditional of tractor hoist, pull in tractor hoist control room action bars taking special staff as main, under normal circumstances, operation team is per hour can be promoted or the quantity of lower drain line is no more than 70.
Through the literature search of prior art is found, Chinese invention patent (201110206972.2), Chinese utility model patent (201120238629.1, 201020175311.9, 200820218538.X, 200420053570.9, 99243437.8, 94225440.6, 02270736.0, 200820054835.5, 201320058679.0) and journal article " development of TJ70DB electric well dredger and application " (author Yuan Lifeng) and " development of novel hydraulic wheeled tractor hoist " (author Chen Yiliang etc.), in these document designs or disclosed tractor hoist, all be provided with control room or console, all need special staff to operate tractor hoist.Thus, in operation, the operation of tractor hoist is still pulled action bars as main taking special staff in control room.
Summary of the invention
The object of the invention is to the problems referred to above that exist in current workover treatment, a kind of intelligent electric drifting device adopting and method are provided, the height of control oil pipe accurately and timely, be not equipped with special operating room or control room, having reduced workover treatment needs staff's number, there is little, real-time, the simple to operate characteristic flexibly of volume, and solve the deficiency in above-mentioned background technology, to meet better the needs at workover treatment scene.
For achieving the above object, the present invention is achieved by the following technical solutions:
A kind of intelligent electric drifting device adopting, comprises elevator, suspension ring, hook, running block, wire rope, top fixed pulley, derrick, end fixed pulley, cylinder, rear shaft coupling, reducer, brake, front shaft coupling, switched reluctance machines, the first power cable, control box, signal-transmitting cable, control module, the second power cable, industrial power lead-out terminal, upper stroke switch, lower stroke switch, chassis and earth anchor; Described derrick, end fixed pulley, cylinder, reducer, brake, switched reluctance machines and control module are all fixed on chassis; Chassis by earth anchorage on the ground, is not moved while ensureing whole device work and turns on one's side; The hub that connects of oil pipe sits on elevator, and described elevator hangs over the lower end of suspension ring, and the upper end of described suspension ring hangs on hook, and the upper end of described hook is connected with running block, described running block connecting steel wire ropes; Described top fixed pulley is fixed on the most significant end of derrick, and the center of top fixed pulley is on the center line of well head; Described wire rope passes from the wheel hub of top fixed pulley, and is connected on cylinder by end fixed pulley; Described cylinder rear end is by rear shaft coupling connection reducer, described reducer rear end connecting brake, described brake rear end is by front shaft coupling connecting valve reluctance motor, described switched reluctance machines rear end is by the first power cable connection control unit, described control module connects industrial power lead-out terminal by the second power cable, described control box, upper stroke switch, lower stroke switch are by signal-transmitting cable connection control unit, described upper stroke switch is fixed on the upper end of derrick, the below of top fixed pulley; Described lower stroke switch is fixed on the lower end of derrick, the top of well head; When hook upwards operation always, while exceeding a certain maximum displacement, hook touches upper stroke switch, and upper stroke switch sends to control module the signal that shutdown switch reluctance motor rotates; When hook operation downwards always, during lower than a certain least displacement, hook touches lower stroke switch, and lower stroke switch sends to control module the signal that shutdown switch reluctance motor rotates.In described control box, there is speed governing knob, promote oil pipe button and lower drain line button.
A kind of intelligent electric drifting method, comprises the steps:
1) clear up the scene of oil well to be repaired, intelligent electric drifting device adopting is placed on apart from well head a distance, make the center of top fixed pulley on well head center line; Make earth anchor, chassis is fixed on the ground; Control module is connected to by the second power cable on the industrial power lead-out terminal of oil wells in field;
