The drilling equipment consists of eight systems: lifting system, rotating system, circulating system, transmission system, driving system, control system, drilling rig base and auxiliary equipment. Drilling equipment is divided into rotation, lifting, circulation, power and transmission, control and other systems according to function: Drilling rig nd Workover Rig Equipment,Oilfield Rig,Truck-Mounted Drilling Equipment,Air Winch And Drawworks Drilling Rig Henan Youlong Petroleum Engineering Technology Co.,Ltd , https://www.youlongenergy.com
1. The main equipment of the rotary system is the Rotary Table installed on the wellhead of the drill floor. During rotation, the drill string and bit are driven to rotate and drill through the Kelly. When the downhole power drilling tool is used to drive the bit to rotate, the rotary table is used to bear the reverse torque.
2. The hoisting system is a set of hoisting equipment composed of winch, derrick, crown block, traveling block, hook, steel Wire Rope , etc. The winch is mainly used to trip the drilling tool, run the casing and control the WOB during drilling. The derrick is used for placing crown block, hanging traveling block, hook and other lifting equipment and tools, as well as lifting and storing pipe string. The crown block and traveling block are a set of complex pulley device to reduce the tension on the winch wire rope. The number of wire ropes of the complex pulley of large and medium-sized drilling rigs is generally 8 ~ 12 strands.
3. The mud circulating system is composed of Mud Pump , high-pressure mud pipeline, water hose, faucet, drill string and mud Solid Control Equipment.
4. Solid control equipment is used to remove useless solid particles in the mud returned from the well. The commonly used equipment includes vibrating screen, Desander , Desilter , degasser and centrifugal separator. In the late 1970s, the automatic mud preparation system began to be used in combination with the well control device, which can reliably control the wellbore at any time and automatically keep the mud specific gravity constant. In case of blowout omen, it can automatically adjust the mud specific gravity and other properties.
5. Power and transmission system includes power machine and transmission unit. The power engine mainly uses diesel engine, motor or gas turbine. The transmission unit includes mechanical transmission such as chain, belt and gear, hydraulic transmission and electric transmission to transmit power to working machines such as winch, rotary table and mud pump.
6. The control system enables each unit to work coordinately according to the needs of drilling technology. It includes the control of starting, stopping, speed regulating, paralleling and reversing of power machine, winch, rotary table and mud pump. The methods include mechanical, pneumatic, hydraulic and electric control, and develop in the direction of electronic computer control.
7. Well control equipment is an important equipment used to ensure safe drilling in oil and gas drilling, including BOP, Choke Manifold, kill manifold, Mud Gas Separator, etc. The blowout preventer is used to prevent the blowout of mud, oil, gas and water in the well. The blowout preventer includes ram blowout preventer, rotary blowout preventer and universal blowout preventer. It is installed at the wellhead under the drill floor and is used to close the annular gap between the drill string and casing or all wellhead respectively. In addition, there is a blowout preventer in the drill string, which is used to close the internal space of the drill string. Modern drilling equipment is equipped with several sets of different types of BOP to form wellhead BOP group to control different drilling conditions.
Excerpts from the Chicago Tribune:
Local law enforcement and emergency services in western Will County are feeling overlooked as the county moves forward with plans to construct a consolidated dispatch center for 30 agencies in eastern Will County. These agencies argue that if the county is funding a new dispatch center for one set of agencies, it should extend the same financial support to others.
The $5 million initiative to integrate this new dispatch center with the construction of a new Sheriff’s Office facility later this year has been labeled "generous but deeply flawed" by the Bolingbrook Village Board in a recent resolution. However, county officials view this consolidation as a cost-effective approach to governance, akin to prioritizing road maintenance in certain areas over others. State regulations have necessitated the reduction of dispatch centers from six to three in Will County.
According to state mandates, the Will County Sheriff’s Office, Lincolnway Communications Center, Romeoville, and Eastern Will County Communications Center (EASCOM) will merge into a single facility located at Laraway Road and Route 52. This new hub will also house administrative offices for the county’s 911 board. Agencies under the Western Will County Communications Center (WESCOM), which currently manages calls for 21 police and fire departments spanning from Bolingbrook to Wilmington, are expected to back Bolingbrook's stance, emphasizing the need for a fair resolution. WESCOM had taken on a $5 million bond in 2014 to fund its current dispatch center in Plainfield.
At a recent Lockport City Council meeting, Police Chief Terry Lemming expressed satisfaction with the state-mandated consolidation, acknowledging its potential for improved coordination. However, he and other council members remain dissatisfied with the notion that residents across the county, including those in Lockport, will bear the financial burden of the county’s $5 million project.
WESCOM representatives insist this is not a matter of envy but of fairness. The Lockport City Council is contemplating adopting a similar resolution to advocate for equitable treatment. Homer Township Fire District is anticipated to follow suit at its upcoming meeting in May.
Tom Ross, Bolingbrook’s Public Safety Director, highlighted the inequity faced by agencies served by WESCOM, who are essentially paying twice—once for their own dispatch center and again via county funds allocated to the new Sheriff’s Office facility.
Crete Mayor Mike Einhorn, who heads EASCOM, which serves 16 police and fire agencies, voiced his skepticism over claims of equity. He pointed out that most county expenditures favor eastern regions, suggesting that similar equity arguments could be made elsewhere but are typically dismissed.
County officials counter these claims by arguing that investments in infrastructure, such as dispatch centers and roads, ultimately benefit all county residents. They emphasize the importance of collaboration and efficiency in government operations.
While WESCOM serves 44% of the county’s population across 21 agencies, the new center will cater to 33.7% of the population and 31 agencies. Joliet, serving 21% of the population, handles approximately one-third of all calls. There are concerns among some agencies that the new center might attract member agencies away from WESCOM, particularly given its capacity for expansion. For instance, Romeoville residents might find joining the new center more advantageous, potentially reducing transferred calls by 3,600 annually.
Despite these challenges, Rauter, representing WESCOM, remains hopeful for dialogue with agencies considering a move, even if they choose to leave WESCOM, they would still be obligated to honor their existing financial commitments.
Meanwhile, Braidwood officials, currently part of WESCOM, are weighing the possibility of transitioning to the new center. Rauter aims to address their concerns directly, hoping to maintain their membership while acknowledging the difficulty of competing against what appears to be a free service.
