The invention provides a water hammer pressure wave signal simulation system which comprises a fluid storage tank, a plunger pump, a plunger pump console, a sand adding device, a sand storage device,a simulation crack, at least two high-frequency pressure sensors and a pipeline. The fluid storage tank, the plunger pump, the sand adding device, the simulation crack and the at least two high-frequency pressure sensors are sequentially connected through pipelines. The plunger pump console is connected with the plunger pump so as to control whether the plunger pump works or not; when the plungerpump works, the plunger pump is used for injecting fluid in the fluid storage and collection tank into the pipeline; the sand adding device is connected with the sand storage device and used for adding the propping agent in the sand storage device into the pipeline and stirring the fluid and the propping agent into fracturing fluid; the at least two high-frequency pressure sensors are used for detecting water hammer pressure wave signals in the pipeline when the pump is stopped. According to the system disclosed in the solution, the water hammer pressure wave signal formed when the pump is stopped in hydraulic fracturing can be simulated, and a basis is provided for fracturing diagnosis based on the water hammer pressure wave.
Description
technical field [0001] The present application relates to the technical field of fracturing in oil and gas field development, in particular to a water hammer pressure wave signal simulation system. Background technique [0002] At present, hydraulic fracturing is an important means of unconventional oil and gas development. Hydraulic fracturing works by pumping fluids into the surface to open fractures in the formation, providing pathways for oil and gas to migrate. Fracturing diagnosis is used to analyze the location and shape of fractures at the bottom of the fracturing well, evaluate the fracturing effect, and provide a basis for fracturing design and optimization. [0003] However, since the hydraulic fracturing operation is carried out thousands of meters underground, and the geological conditions at the bottom of the well are complex, the characteristics such as the location and size of the fracture after the fracturing operation are complex and difficult to predict d...
