Five different ceramic proppant price alone collar "coquettish"


fracturing proppant can be broadly divided into natural and artificial two categories. The former, represented by quartz sand, the latter is often referred to as ceramic proppant. Five different  Ceramic proppant  price alone collar "flair", ceramic with its unique price, product use and other characteristics, a strong win, the momentum is better than the other four proppant.
Oil production in the market currently widely different prices using five standard  Proppant  which are natural quartz sand, synthetic aluminum silicate moderate density proppant ( frac sand ), synthetic high-density alumina moderate and silicate proppant, high strength and high strength bauxite proppant zirconium silicate, and applying a curable coating and pre-cured resin coated proppant natural or artificial sand. They are in the oil and gas production in each plays a different role.
In the success or failure of hydraulic fracturing fracturing effect, validity depends mainly on the quality of the proppant. The role of the proppant fracturing generated hydraulic fracturing  filled, so that no re-closure, and having a high conductivity to form a flow channel. In the reservoir characteristics and fracture geometry under the same conditions, fracturing wells yield and production dynamically depending on fracture conductivity. Crack fracture conductivity is conduction (transport) capacity reservoir fluid and proppant to fracture permeability layer (Kf) and fracture bracing slit width (Wf) of the product [KW] f to represent. Generally,  Proppant  type, physical properties (grain size, strength, ball, roundness, density, etc.) and their distribution in fractures (laid concentration per unit area of ??a support crack dose), and crack closure Stress is a major controlling factor in fracture conductivity.
Therefore, mastering the physical properties of the proppant fracture conductivity and impact of many factors conducive to a rational choice of proppant, it is beneficial for the fracturing fluid and proppant fracturing materials made more precise requirements.
