RockySea Petro Skid-mounted fracturing equipmentDescriptionIn the field of petroleum, hydraulic fracturing refers to a method of using hydraulic action to form fractures in oil and gas reservoirs during oil or gas production, also known as hydraulic fracturing. After a certain stage of oil well production, the production capacity and permeability decrease. In order to enhance oil drainage capacity and increase oil well production, people have invented fracturing technology. The methods of
