Introduction:

（1）DAS / DSS can also receive clear low-frequency strain signals and microseismic signals in adjacent wells.

（2）The temporary optical fiber fracturing monitoring technology of adjacent wells greatly reduces the monitoring cost and construction risk. It can be implemented simultaneously in multiple horizontal wells on the same platform to achieve comprehensive real-time monitoring.

（3）Through the low frequency signal and microseismic signal generated by the formation strain, the fracture development process is intuitively described.

（4）North America fracturing monitoring workload ranks first, mature technology.

（5）This technology is still blank in China.

Technical status quo：

Optical fiber adjacent well fracturing monitoring technology : At present, the most important application in the shale oil and gas region of the United States is to understand the number of perforation opening clusters, the width and orientation of each fracture reconstruction, and to identify inter-well and inter-section interference. Through real-time monitoring of low-frequency strain signals, the development process and state of fracturing fractures are described, and Party A can make real-time decisions to optimize the fracturing plan. Through the identification of Frac Hit, the relationship between interwell interference and fracturing parameters is confirmed, which provides a very important data reference for the development of well network deployment in the later block. The spacing of infill wells in the horizontal and vertical directions of the reservoir is adjusted to adjust the fracturing scale and achieve the best fracturing effect to obtain the maximum productivity.
