Petroleum proppant known as proppant in hydraulic fracturing in fracturing effect greatly affect the success or failure

Petroleum proppant known as proppant in fracturing proppants hydraulic fracturing in fracturing effect greatly affect the success or failure, depending on the length of validity of the quality of the proppant. After its role in the oil and gas when deep mining, high closure pressure after fracturing low permeability deposit processing, the hydrocarbon-bearing formation split, passage of oil and gas from the cracks formed in the collection out of the fluid injected into the rock grassroots needs at this time, in order to formation fracture pressure exceeds the strength to make cracks in the rock around the wellbore to form a channel having a high level flow capacity, cracks formed to maintain Open after fracturing oil and gas product can be smoothly passed.
Fracturing proppant can be broadly divided into natural and artificial two categories. The former representative of quartz sand, which is commonly referred to as ceramic proppant. The price of the widely used five different standard proppant in the oil and gas yield market, which is a natural quartz sand, artificial moderate density silicate proppant (ceramic sand), moderate-intensity artificial high density alumina and silicate proppant, bauxite high strength and high strength proppant zirconium lightweight proppant silicate, and applying pre-cured coatings and coating resins curable natural or artificial sand proppant. They each play a different role in the oil and gas production.
