On June 26, 2015, the first Futian Cummins & Futian Oumac “Fukang Cup†State IV Service Skills Competition finals were held in Beijing in June 2015. This event is divided into two parts, theoretical knowledge competition and electrical system troubleshooting. Futian Cummins hopes to train its technical backbones and improve service skills for after-sales service dealers across the country through this competition. It aims to provide efficient and efficient service to Futian Ouma and Foton Cummins users. As Ma Tian, ​​director of customer support department of Foton Cummins, said, the era of electronic control of China's diesel engine is only really coming after the implementation of the National IV emission standard. Due to the different implementation time of the country's four national regions, the country’s regional service dealers There is a difference in the level of understanding and understanding of the National Diesel Engine. In order to solve the problem of uneven regional service dealers' level of maintenance services for the State Fourth Engine , Futian Cummins has been providing technical guidance to them in the cycle of knowledge training, skills testing, and service competition in the past two years. The reason why the "Fukang Cup" National IV Service Skills Contest Final was held was to test the results of the previous guidance. The ultimate goal of Foton Cummins is to provide users with more reliable and more comfortable after-sales services through training and training. service. In the session of the theoretical knowledge contest, Foton Cummins prepared test questions for 44 contestants from all over the country, including single choice, multiple choices, judgments, and short answers. The content of the questions was set mainly around the conventional maintenance knowledge of the National IV engine. Common fault analysis and other aspects. An athlete from Shenyang interviewed a reporter from China Truck Network: “This theoretical knowledge contest is very meaningful. Because the exam is very focused, this exam has given me an understanding of the theoretical knowledge I have learned. With a deeper impression, I have also been guided by my peers after the examination. I believe that my thinking will be more open and accurate in the actual troubleshooting. †As the saying goes, “Practice is the sole criterion for testing truth.†Can the theoretical knowledge in the morning be used in actual vehicle maintenance? We found the answer in the electrical system fault diagnosis practical game held in the afternoon. The electrical system fault diagnosis actual operation competition set a total of four major faults: the engine computer does not supply power, the diesel oil-water separator circuit is broken, the engine intake pressure sensor is disconnected, and the exhaust brake cannot work properly. The failure of the engine computer to supply power was caused by the inspector unplugging the computer-powered fuse. It tested the contestants' familiarity with the use of the vehicle cutouts in the layout of the vehicle and the use of the circuit diagram of the vehicle. It also trained and tested the contestants. The electrical appliance malfunctions the correct maintenance idea of ​​the basic inspection first; the diesel oil-water separator and the engine intake pressure sensor are disconnected due to the inspector's disconnection of the circuit connection plug, and the two faults test the contestants as the candidates for the second exam. The proficiency of the ammeter and the ability to troubleshoot the wiring of the vehicle; the inability of the exhaust brake to function properly is due to the disconnection of the power switch of the clutch pedal. It tests the participants’ knowledge of the working conditions of the engine exhaust brake system. Understanding degree. From the winner of the final champion Xia Guoan of Shaanxi EAST, the master said, “In fact, most of the vehicle circuit failures are caused by short circuits caused by abnormal wear of electrical circuits and circuit breakers that cause electrical components to supply power abnormally. The failure setting of the Futian Cummins Examiner not only meets the actual maintenance requirements but also tests our basic maintenance ideas and the understanding of the unique electronic control system for the State IV vehicle. The probability of these theories and practical operations in our actual maintenance is at 50 More than %, they are really great!" People often say that the use of troops for a thousand days is a time when Futian Cummins's implementation of the after-sales service team is a matter of training troops for a long time. Perhaps as pointed out by Peng Shishun, service director of Futian Omar Marketing Co., Ltd.: “What I have achieved for you today. I'm glad to also hope that you will be able to share today's gains and your long-term accumulated practical knowledge with each other through today's platform and bring them to your service team. For the users of Foton Cummins and Foton Oumac Going to the best service experience is my highest expectations for you!
Casing is a large-diameter pipe that serves as the structural retainer for the walls of oil and gas wells or wellbore.
It is inserted into a well bore and cemented in place to protect both subsurface formations and the wellbore from collapsing and to allow
drilling fluid to circulate and extraction to take place
The oil casing is a steel pipe used to support the well wall of oil and gas wells to ensure the normal operation of the whole well during drilling and after well completion. Several layers of casing shall be used for each well according to different drilling depth and geological conditions. Cement shall be used for cementing after casing is put into the well. It is different from TUBING and drill pipe and cannot be reused. It is a disposable consumable material. Therefore, casing consumption accounts for more than 70% of all oil well pipes.
Casing is a large-diameter pipe that serves as the structural retainer for the walls of oil and gas wells, or wellbore. It is inserted into a well bore and cemented in place to protect both subsurface formations and the wellbore from collapsing and to allow drilling fluid to circulate and extraction to take place.
Surface casing
- Protects the well from contamination in shallow water and gas layers.
- Supports the wellhead equipment and sustains the weight of the other layers of casing.
Intermediate casing
- Isolates different layers of pressure to facilitate normal circulation of drilling fluid and protect the production casing.
- Intermediate casing facilitates the installation of blow-out preventers, anti-leakage devices and tailpipes in the well.
Production casing (oil string)
- It is the conduit through which oil and gas pass from a below surface reservoir.
- It protects the well and separates fluids into various layers.
First, green pipes are threaded on each end. The threading is then inspected and, if necessary, rethreaded to ensure that the thread accurately connects to the coupling. The threading type includes STC/BTC/LTC. The casing pipes are strengthened by surface treatment and are subject to various inspections, including drifting and hydrostatic tests before they are coated and packaged into casing.
Casing pipes are ordinarily produced with outside diameter sizes of 114.3 mm to 508.0 mm.
