Energy dissipation wells are wells set up in the middle of a downhill slope or on the road. The depth is generally determined based on the slope.

The function of the pressure well in the building: pressure regulation. Since the water diversion pipe of the power station is long, when the unit suddenly drops the load and closes the guide vane during operation, there will be a large water hammer effect due to the inertia of the water flow. , if there is no pressure regulating well (also called a pressure well), water hammer will destroy the water guide vane and other flow-passing components. The function of the pressure regulating well is to provide a release channel for water hammer to reduce the pressure of flow-passing components.

Influencing factors

Balanced pressure drilling is mainly done by controlling the additional density value of the drilling fluid, optimizing the well structure, controlling the tripping speed, optimizing the rheology of the drilling fluid and the displacement of the drilling fluid. etc. to control bottom hole pressure. Therefore, the mud column pressure, well structure and tripping speed all play a vital role in the practical application of balanced pressure drilling technology.
