Impact of source models on focal mechanism inversion in hydraulic fracturing distributed acoustic sensing monitoring

Distributed acoustic sensing (DAS) has garnered growing attention for microseismic monitoring in hydraulic fracturing (HF) operations within unconventional oil and gas development. Conventional DAS sensors acquire single-component measurements along the optical fiber, which may introduce uncertainties in microseismic f...

Research on Application Technology of Laser Welding in Oil Downhole Instruments

With the continuous development of oilfield exploitation technology, ultra-high temperature and ultra-high pressure well conditions are increasing, and the requirements for downhole instruments to resist high temperature and high pressure are also increasing day by day. The traditional fluororubber O-ring seals used in...
