The construction task is the JH-SK003 team of Bazhou Project Department of Jianghan Petroleum Engineering Survey and logging company

The 9 day

Start at 10:00

The 10 day

02:30 to Manasi County accommodation, the local start to snow, 14:00 to the well site to get involved in advance.

The 11 day

The temperature of the mountain reaches 2 degrees below zero, and the JH-SK003 team works for 8 hours continuously. The construction tasks of the perforation and the first logging temperature are successfully completed.

But for the timeliness of temperature logging operations, a temporary second changes of temperature logging in four hours after fracturing, the original 11 pressure equipment starting from the tire base, only a temporary advance to the day starting at 19:00, because the road is far, traffic jam, on the downhill more, until the second day at 17:00 with pressure equipment to round the clock at the job site.

The 12 day

At 17:00, the pressure equipment was safely transported to the wellsite. Because of the low temperature, the JH-SK003 team changed the winter sealing grease in time.

Because the working environment is not good, the well site is uneven and the space is narrow, which adds difficulties for the field workers to connect the pressure equipment, and it takes more than 4 hours to connect the equipment well.

The 13 day

03:00, the crew fracturing finished, temperature has dropped to minus 10 degrees, in order to prevent the temperature is too low, the risk control head was frozen, the players put down the blowout preventer, and wrapped in the insulating film and the appearance of tropical.

Although prepared, but when the instrument into the wells delegated to the flat valve when suddenly difficult. After careful analysis by technicians, it is confirmed that the inner wall of Iguchi Hirasaka and the four link is frozen, resulting in smaller path. Finally, the card was solved by adding salt, diesel and antifreeze to the well.

Low temperature not only brings trouble for construction equipment, but also for construction workers. Their workers’ trousers are wet by water and ice is formed, and gloves are also mixed with ice and water.

Until 20:00, the second well temperature operation was completed.

Back to the lodging place, the JH-SK003 team had been working for 24 hours in the early morning hours, while the master Miao Lixin, who was carrying the pressure equipment car, had only rested for four hours in the two days of construction.

The 14 day

08:00, the team members came to the well, the same environment, the white snow mountain, the muddy well.

After the 19:00 bridge plug tools start out, the sealing 20MPa is qualified and the seat seal is successful. After the cable hydraulic bridge plug is put into use, the success rate of the seat seal is 100%.

The 15 day

Starting with 08:00, the pressure perforation and third logging temperature are still arranged at night.

The 16 day

In the construction of heavy snow, everyone stick to their posts, after fracturing third logging temperature curve has been recognized by Party A.

The ground is seven or eight centimeters thick when you pack up the tools and pack the pressure equipment car and get ready to return.

The thick snow, the rugged road, the players have to take the initiative to get off, master Xiao Yong and Zhao Kai took the wood for the car in the mask, put the mask slip in wood, Wang Xiaolong and Wei Zuowang holding shovels, and stones and soil on slippery pavement, vice president Tian Zhipeng and Miao Lixin walking command vehicle we have been, so go five kilometers, after it was sweating.

Starting from the 11 day to the 18 day of the Luntai base, the safe return of logging company Bazhou project department JH-SK003 team finally successfully completed the conventional cable bridge plug and perforation, with pressure with pressure perforation and pressure temperature logging construction tasks, with action in the snow in the writing of their youth, to show the brand image of Jiang Han iron perforation
