How to operate oil drilling rig can be more convenient

1. selection of drilling tools and processes should be reasonable Choosing appropriate drilling tools according to the construction geological conditions can not only save fuel but also protect the drill pipe. When drilling is difficult, the drilling speed can be improved by changing the drilling mode through different drilling combinations. In the process of large-diameter pile formation, small-diameter drilling tools are first used for drilling and then large-diameter drilling tools are used for reaming, which can effectively reduce resistance and improve drilling efficiency. The drilling of hard stratum shall be of jog pressure type, the drilling of loose soil stratum shall be of long stroke pressure type, and the pressure raising and pressurizing method shall be selected when drilling floating stone. According to different geology and hardness, the reasonable pressure method shall be selected, which can also improve the construction efficiency of drilling rig and effectively reduce oil consumption. After the drilling tool is filled, the power head shall be properly rotated during lifting, which can reduce the lifting resistance and fuel consumption. The idle speed function of the 2. should be integrated, and the selection of drilling tools and processes should be reasonable.

Role of power of workover rig

1. The power of the workover rig is generally high-speed diesel engine. In terms of power equipment, it is divided into single engine and dual engine. The single engine is on the car and shared under the car. The dual engine is divided into the car, and the two engines are shared under the car. On the car, one engine supplies power under the car, 2. There are two independent hydraulic systems in the workover rig, the main hydraulic system and the hydraulic power steering system. (1) The primary effect of the main hydraulic system is the vertical release of leveling vehicles and derrick after the workover rig is in place at the well site, as well as auxiliary operations such as hydraulic winch, hydraulic cylinder collapse and hydraulic tongs. (2) The hydraulic power steering system is used to reduce the strength of the rolling steering wheel when the vehicle is running. 3. The workover rig is generally welded with high-strength angle steel and hollow truss structure. The derrick of large-tonnage workover rig can also be welded with high-strength rectangular tubes. The workover rig can have one section and two sections according to different workover rig types. The workover rig of small-tonnage generally selects one derrick. 4. The transmission part generally uses the engine and the hydraulic mechanical gearbox to connect directly. If two engines are shared on and off the car, which requires a parallel car box, the hydraulic mechanical gearbox and the parallel car box, and the angle transmission box. Connect, then connect through the chain and the sand fishing roller or the main roller, then through the chain to the turntable angle transmission box, and the climbing chain box to the turntable. It can also be directly from the parallel car box (angle transmission box) through the transmission shaft to the climbing chain box to the turntable. Sand drum, main drum and turntable are generally controlled by pneumatic push plate clutch, or pneumatic tire clutch 5. The gas circuit system in the workover rig has the primary control effect, such as the clutch, the throttle of the engine, the gear shift of the gearbox, the control of the hydraulic pump, and the control of the throttle and brake when the workover rig is running.

Common maintenance methods for drilling rigs

Useful maintenance of machinery and equipment is divided into daily maintenance, primary and secondary maintenance. Daily maintenance is the protection of machinery and equipment in normal operation by the operator. Set up the mechanical equipment operation table and record the daily operation situation in detail. Check, clean and lubricate the machinery and equipment every day, and clean the oil cup, oil hole, oil pool and oil line every week. In the process of inspection found equipment, machinery defects or damage should be registered in a timely manner, and reported to the relevant departments, tell the repair personnel to repair in a timely manner. In the daily operation of machinery and equipment, it is necessary to strictly operate in accordance with the operating rules. Level 1 maintenance refers to the primary maintenance of machinery and equipment within a certain period of time when the equipment and machinery are operated. Under normal circumstances, the time of first-level maintenance can be regulated according to the specific maintenance requirements of machinery and equipment. Assuming that there are no rules, a reasonable confession can be made according to the actual situation, such as 600 hours. In the first-level maintenance, technicians dredge the oil circuit of machinery and equipment, fasten parts, replace felt pads, and disassemble and maintain messy parts. 3. The workover rig manufacturer indicates that it is necessary to maintain the machinery and equipment after the normal operation of the machinery and equipment exceeds 3000 hours, I .e. secondary maintenance. Check whether the parts are worn, replace and wipe them, adjust the operation accuracy of mechanical equipment, and improve the operation quality. Check and repair the electrical system by the electrical personnel.

How to maintain the workover rig daily

1 Maintenance of workover rig parts. If the hydraulic equipment of the workover rig fails, it will affect the normal operation of the entire equipment. Therefore, the maintenance of hydraulic equipment is very important for workover rig. It must be remembered that the pressure of the hydraulic system cannot be adjusted casually on site, because it has been adjusted before leaving the factory. And when replacing the hydraulic oil, remember not to open the manhole cover. If the working environment is poor and dusty, the filter element should be cleaned and replaced regularly. Also pay attention to check whether the oil level in the car is stable. 2. For the maintenance of the transmission part, first check the degree of chain wear of each part, such as rollers, bearings, etc., to ensure that the oil level of the chain box is stable. Pay attention to check whether the dead end and live end of the brake belt are accurate, and replace them in time if there is any change. Pay attention to the degree of wear between the bearing and the transmission device, and add grease in time. Such as smooth oil level of gearbox, abnormal noise, abrasion of crown block pulley bearing, abrasion degree of traveling block hook pulley bearing, etc. It is worth noting that the height of the brake handle can be adjusted. If the adjustment is not correct, it may happen that the brake cannot be braked or the idling traveling car cannot be lowered. The correct adjustment height is 3-5mm. Finally, remember to check the connecting bolts of each part frequently to see if they are loose. The maintenance of the gas path system is related to the above two parts, and the maintenance of the gas path system is relatively simple. Check the main drain valve and dryer for air leakage and outstanding working condition. Check whether the belt tension of the pump is correct. Pay attention to the rubber pipeline of the gas path system for aging or cracking, and repair it in time. Also pay attention to the components, pipes and joints of the gas pipeline system to see if there is any leakage or looseness.
