Type of proppant

fracturing proppant can be divided into natural and artificial two categories. The former representative of quartz sand, which is commonly referred to as ceramic proppant. hsp proppant is now widely used in oil and gas prices increase market five different standards proppants, which are natural quartz sand, artificial moderate density aluminum silicate proppant (ceramic sand), High crush proppants  of moderate-intensity artificial high density alumina and silicates proppant high-strength and high-strength bauxite proppant zirconium 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.

Hydraulic fracturing fracturing effect depends on the length of validity of the quality of the proppant

In hydraulic fracturing in fracturing effect the success or failure depends primarily on the length of validity of the quality of the proppant. Ceramic proppant role is to produce hydraulic fracture fracture filling, making it no longer re-closed and form a flow channel having a high conductivity. In the reservoir characteristics and fracture geometry the same conditions, fractured wells increased yield and production performance depends on the conductivity of cracks. Fracture conductivity refers to a fracture conductivity (transport) capacity reservoir fluids, and to crack proppant permeability (Kf) layer and the support crack slit width (Wf) of the product [KW] f to represent.

 Generally believed that the type of proppant, physical properties (size, strength, ball roundness, density, etc.) and their distribution in the fracture of (laid concentrations that support the dosage unit fracture area), as well as crack closure Stress is a major factor controlling fracture conductivity. Therefore, the master Ceramic proppants physical properties and fracture conductivity and many other factors, there is a reasonable choice in favor of proppant fracturing favor fracturing fluid and material support agents made more precise requirements. Type from the proppant, physical properties and evaluation methods proppants fracture conductivity and its influencing factors, and selection of proppant four face proppant and fracture flow capacity to make a presentation.

Hydraulic fracturing proppant is important to fill the media

http://www.maideceramics.Hydraulic fracturing  technology is an effective technology fields to increase production. The process is to use high-pressure pump on the ground, the high viscosity of the fracturing fluid to significantly exceed the absorptive capacity of the formation of the displacement is injected into the well at the bottom Biechu hypertension; when this pressure is greater than the near wellbore formation stress and When the tensile strength of the rock formations in the vicinity of the bottom layer can crack; continue to inject liquid with sand proppant, fracture extending forward and pressed (fracturing proppants

extending forward and pressed fracturing proppants Filling, shut after fracture closure on the filling of proppant, and finally cracks with a geometry and conductivity in the vicinity of the bottom layer, to facilitate faster inflow of crude oil around the bottom of the well, to achieve the purpose of increasing production. As hydraulic fracturing proppant filling an important medium, which directly affects the capacity of the entire yield wells. Therefore, the study of high performance oil proppant for oil yield is very necessary. Oil fracturing proppant * Major points of natural quartz sand, artificial ceramic proppant, resin-coated proppant (ie coated proppant) three categories, including coated proppant is divided into two coated sand and ceramic coating species.
