Technical Field

Background

In the field of oil and gas exploitation, fracturing operation refers to a technology of forming cracks in oil and gas layers by using high-pressure fracturing fluid in the process of oil or gas exploitation. The fracturing operation can lead the oil-gas layer to form cracks, thereby improving the flowing environment of oil or natural gas in the underground and increasing the yield of the oil well.

The fracturing technology is one of core technologies for shale gas development, and can be widely applied to shale reservoir transformation and shale gas exploitation.
