Hydraulic fracturing is an oil and gas well stimulation measure with wide application prospect. This method uses the surface high-pressure pump to squeeze and inject fracturing fluid with high viscosity into the oil layer through the wellbore, press the oil layer open and produce fractures
When the injection rate of fracturing fluid exceeds the absorption capacity of the oil layer, the oil layer at the bottom of the well will form a high pressure.
as to establish a new fluid channel between the oil layer and the wellbore, The production of oil and gas wells will generally increase greatly. But this technology will bring great damage to the environment.
