6834 Meters! Setting a New Domestic Record for the Deepest Casing-External Optical Fiber Cable in Horizontal Wells!Casing-Evading Optical Fiber Cable, Manufactured by Huaneng

Huaneng Cable Supplies Optical Fiber Cables for the Mahu MYHW1003 Well of Xinjiang Oilfield

Huaneng Cable has provided optical fiber cables for the Mahu MYHW1003 Well of Xinjiang Oilfield. The well is currently in the well shutdown phase following fracturing operations and is expected to be put into production and fluid extraction in more than ten days.

On October 13th, the horizontal well external-casing optical fiber fracturing monitoring test conducted at this well was successfully completed. This test achieved two significant outcomes:

1. The length of the optical fiber cable deployed into the well reached 6,834 meters, setting a new domestic record for the deepest external-casing optical fiber placement in horizontal wells.

2. The directional perforation success rate while avoiding the optical fiber cable reached 100%, establishing a new domestic benchmark for the oil and gas industry.

In recent years, Xinjiang Oilfield has established a joint project team to conduct systematic research on the technology for fracturing monitoring using external-casing optical fibers in horizontal wells. The team has focused on overcoming key technical challenges, including the safe deployment of long horizontal-section optical fibers into the well and the precise positioning of external-casing optical fibers. This research provides crucial technical support for ensuring stable and increased production of shale oil in the Mahu area.

From September 22nd to October 13th, the MYHW1003 well successfully completed 37 stages of directional perforation avoidance and fracturing operations across 168 clusters. No optical fiber cables were damaged during the entire operation, achieving a 100% success rate in avoiding the optical fibers during perforation.

The fiber optic monitoring system real-time visualized the dynamic processes of bridge plug setting, cluster perforation, and fluid injection for each cluster. It enabled online monitoring and evaluation of the stimulation effect of each cluster, fully meeting the objectives of the test.
