At the end of the year and the beginning of the year, the Xinjiang Project Department of Zhongyuan Petroleum Engineering Pipe Co., Ltd. came with good news one after another: the TKK3-2-1H well guaranteed in November 2023 set a record for the longest clastic rock horizontal section, the fastest mechanical ROP and the shortest cycle in the Tahe block, and the ultra-deep well guaranteed in December - Shunzhong 1 inclined well saved the drilling cycle of 3674 days.
The Xinjiang Project Department provides all-weather support for drilling tools and tools for the well team, strengthens the quality management of the whole life cycle of drilling tools and tools, and provides "gold medal nanny" services for the drilling team in the desert. In 2023, the Xinjiang Project Department will guarantee a total of 67 new wells and 71 completed wells, and hand over high-scoring answers in the service of deep-ground drilling.
"Special forces".
At 3 a.m. on December 4, 2023, Li Yao, deputy manager of the Xinjiang Project Department, suddenly received an instruction from the Technology Development Center of the Northwest Work Zone of Zhongyuan Petroleum Engineering Company: Well TP1115X urgently needs 400 drill pipes, and the quality inspection and loading must be completed within 24 hours!
Li Yao met with Xu Yong, the director of the pipe repair workshop, and Ren Li, the leader of the inspection team, and the pipe repair workshop immediately turned on the assault mode. The employees of the inspection team took turns to go into battle, the automatic cleaning of the drill pipe was non-stop, and the employees of the lathe shift repaired and detected the injured drilling tools at any time. Twenty-three hours later, 400 drill pipes were delivered to the drilling team ahead of schedule.
The Xinjiang Project Department is responsible for the drilling tools and tools support services of 25 drilling teams in the Northwest Work Area of Zhongyuan Petroleum Engineering Company, covering the Tahe, Shunbei, Tazhong and Hetian work areas of the Northwest Oilfield, with heavy tasks.
In 2023, the Xinjiang Project Department will provide a total of 940 kilometers of drilling tools, 33,854 drilling tool joints, 8,153 tools, 1,649 tool joints, and 1,099 new joints.
"Iron Gate God".
The oil and gas in the Northwest Oilfield is deeply buried, and the high stress, high temperature, high pressure and high salinity of the formation are superimposed, which increases the unpredictable risk in drilling, and has extremely high requirements for the quality of drilling tools and tools. We must be the 'gatekeeper' of the quality of drilling tools and tools. Shu Peng, manager of the Xinjiang project department, said.
The staff of the Xinjiang Project Department takes the whole life cycle management of drilling tools and tools as the starting point, strictly controls the inspection, flaw detection and repair of drilling tools and tools, and never allows a drilling tool or tool with injury or illness to go into the well. Every drilling tool and every tool stored by the Xinjiang Project Department has a steel stamp number, which is their "ID number".
Each number has a corresponding paper file and an electronic file. The file completely records the information of these drilling tools, tool arrival acceptance, pre-well inspection, on-site use, repair treatment, maintenance times, and cumulative time of pure drilling.
On December 20, 2023, the cold wind of the desert was pumping on the face, and it hurt like a knife. There was a busy scene in the restoration workshop of the Xinjiang Project Department. Employees first inspect the surface of the drill pipe and tools for damage, and then use ultrasonic and magnetic particles to detect whether there are cracks, fatigue and other internal injuries, which is equivalent to doing "B ultrasound" and "CT" for drill pipes and tools. For drilling tools with serious hidden dangers, they are scrapped according to standards.
Catch up with three drilling teams to drill at the same time, they work in two shifts a day, work hard, and rarely sleep.
Employees know every drill tool and every tool well and cherish it.
"Golden Nanny".
The Xinyuan 2 well is located in Xiaotang Town, Yuli County, in the Taklamakan Desert, 180 kilometers away from the Luntai base.
When this ultra-deep well was drilled to 8,169 meters, the 495 drill pipes in the well, as well as joints and "one-trip drilling" drilling tools, expired, and must be tested and detected.
To transport so many iron guys to the Luntai base, it not only increases the cost of the drilling team, but also affects the production back and forth.
On the afternoon of September 12, 2023, the Xinjiang Project Department was anxious about the urgency of the drilling team and arranged for flaw detectors Guo Junhui and Wen Cen to "go to the clinic".
The desert is a curtain, and the stars are shining. On the well site, the drillers took out one, and they detected and tested one. After 10 hours, it was a perfect call.
Our project department has Sinopec drilling tools and tools Grade A testing qualification, and it is common to go to the well site for testing and flaw detection. Huang Xiaofeng, deputy director of the pipe repair workshop, said, "The farthest well site is in the desert 700 kilometers away from the Luntai base, and you have to run for a day just one way." ”
Difficulties are not fearful, and ambition is stronger than iron.
In order to ensure high-quality and efficient deep-ground drilling, the Xinjiang Project Department has established a "24-hour production support circle" and a "5-hour technical service circle" in the construction area.
They keep in communication with Party A at all times, grasp the production progress of the drilling team, and coordinate the deployment of drilling tools and tools. During the drilling of the key wells, the technicians of the pipe repair workshop took drilling tools and tools to eat and live in the well site to assist the drilling team to solve the problems.
The technicians will give the drilling team engineer a reminder card every time, explain in detail the tensile strength, buckle torque, clasping torque and other parameters of drilling tools and tools, and take the trouble to tell the details and precautions for the use of drilling tools and tools.
They often hold training courses to guide the drilling team employees to correctly use and maintain drilling tools and tools, and provide risk warning services to the drilling team to prevent damage to drilling tools and tools in combination with the penetration rate, pump pressure, drilling pressure and drilling fluid displacement in special well type drilling.
In 2023, the Xinjiang Project Department will assist the Northwest Work Area of Zhongyuan Petroleum Engineering to hold 21 training sessions on the use of drilling tools and tools, with 280 participants.
