Information
In 2015, Fuling shale gas field achieved phase I production of 5 billion m3, while the terrain area for phase II production and construction is extremely complex. The vertical depth of some wells is more than 3500 m, greatly increasing the difficulty of fracturing, higher requirements have been placed on the process, technology and equipment.
Difficulties:
More complex formations, with high deviation well, and the maximum well deviation exceeds 100 degrees;
Higher formation pressure;
Large-span in depth of the target formation, up to 4300 m, and the well temperature exceeds 140℃.
