Recently, Petrochemical Jingwei Jianghan Logging and Logging Branch applied tractor optical fiber monitoring technology to complete the 32-section optical fiber fracturing monitoring task of Jiaoye 11-Z1HF well, marking the first successful domestic tractor optical fiber fracturing monitoring construction
.

Well Jiaoye 11-Z1HF is a development evaluation well in the Fuling shale gas field
.

The purpose of fracturing monitoring of this well is to monitor the development status of hydraulic fracturing fractures and the opening of perforation clusters in real time, evaluate the fracturing effect of the well, and help adjust and optimize the fracturing plan

This construction adopts tractor optical fiber monitoring technology, which is the first time in China
.

During construction, a tractor needs to be used to transport the optical fiber cable to the bottom of the adjacent well Jiaoye 11-S10HF well, and the optical fiber cable is used as the information transmission medium to monitor the entire fracturing process of the Jiaoye 11-Z1HF well

After receiving the task, Jianghan Logging Branch quickly organized technical experts and key personnel to analyze the well conditions, write construction design and emergency plans
.

Arrange the construction team to arrive at the well site in advance to carry out standardized site layout and ground preparation; at the same time, select professional cadres to take turns on duty 24 hours a day, stationed at the site, supervising the construction, and ensuring safety and smoothness

The fracturing operation of the Jiaoye 11-Z1HF well started from the first stage fracturing at 20:00 on July 22 to the end of the 32nd stage at 17:00 on August 2, lasting 261 hours
.

The optical fiber monitoring of the retractor is carried out synchronously throughout the whole process.

The successful completion of the first domestic tractor optical fiber fracturing monitoring construction demonstrated the leading advantage of the "Jianghan tractor" in the industry, marking that Jianghan Logging Branch's optical fiber logging R&D project has successfully entered the commercial application stage, which is for future expansion The market space provides strong support
