Background

Oil field fracturing is a method for forming cracks in an oil layer by utilizing the hydraulic action, and is also called oil layer hydraulic fracturing. The fracturing process of oil reservoir is to squeeze high pressure, large displacement and viscous liquid into oil reservoir by using fracturing truck, and after the oil reservoir is squeezed out of many cracks, proppant (such as quartz sand and the like) is added to fill the cracks, so as to improve the permeability of the oil reservoir and increase the water injection rate (water injection well) or oil production rate (oil well).

Fracturing is an important link in the exploration and development engineering sequence of middle and low permeability oil fields. Due to the limitation of the physical property conditions of the medium and low permeability oil field reservoirs and the pollution of drilling fluid in the drilling process, the oil well has low natural productivity and poor exploitation benefit after perforation, and can be put into normal production only by fracturing.
