Abstract
The invention provides a natural water fracturing construction method for petroleum, natural gas, shale gas, water and other fluid mineral products. 5-60 parts by volume of self-suspension fracturing propping agent is added into 100 parts by volume of natural water to form a propping agent suspension fluid, and then the propping agent suspension fluid is delivered into an underground rock formation. According to the natural water fracturing construction method, an expensive fracturing fluid added with organic polymers is not needed in fracturing, and natural water which can be obtained anywhere is directly used for fracturing. Therefore, pollution is reduced, and cost is reduced. The self-suspension fracturing propping agent adopted in the natural water fracturing construction method is long in suspension time in clear water and can better meet the oil or gas extraction demand. The self-suspension fracturing propping agent can reduce the friction of the fracturing fluid, so that a fracturing propping system adopting the natural water fracturing construction method and an existing fracturing fluid have basic same performance, delivery and flow-back are easy.
