5 indicators of high quality fracturing quartz sand | lzzg

5 indicators of high quality fracturing quartz sand | lzzg

In the petroleum industry, fracturing quartz sand does not really value the content of silica. There is another set of evaluation criteria for good fracturing sand. If your fracturing sand can achieve the following 5 points, then congratulations, you and your fracturing sand will be warmly welcomed by the oil industry. 1. sphericity and roundness Sphericity, well understood, refers to how close the fracturing proppant (ie, quartz sand) is to a spherical shape. The roundness is interpreted as the degree to which the cross-section of the workpiece is close to the theoretical circle. In the eyes of unfamiliar people, the concept of roundness is a bit abstract. In fact, roundness can be understood as roundness in simple terms. The more sharp and sharp the particles are, the worse the roundness is; The sphericity and roundness of natural quartz sand should not be less than 0.6. In actual testing, the proppant sphericity and roundness plates are used to test the proppant sphericity and roundness, see the figure below. 2. Acid solubility Acid solubility refers to the percentage of the mass of a certain mass of proppant dissolved by acid and the mass of the total proppant under the specified acid solution and reaction conditions. Acid resistance is an important indicator of fracturing proppants. Propants with good acid resistance can work longer in acid rock formations and maintain good conductivity. The allowable acid solubility values for proppants of various particle size specifications are shown in the figure below. It is worth noting that the acid solubility index of quartz sand and ceramsite proppant are the same. 3. Turbidity The turbidity of the proppant is the degree of turbidity of the liquid after adding a certain amount of proppant to the specified volume of distilled water and shaking and placing it for a certain period of time. The unit is FTU. The turbidity mainly characterizes the surface finish of the proppant, reflecting the number and size of particles on the surface. According to regulations, the turbidity of quartz sand for fracturing should not be higher than 100FTU. 4. Anti-crushing ability For a certain amount of quartz sand proppant, the crushing rate determined by the pressure test under the rated pressure characterizes the proppants resistance to crushing. The main factors affecting the crushing rate are the roundness, sphericity, surface finish, and microstructure of the quartz sand proppant. The fracture rate of quartz sand proppant affects the fracture conductivity. The crushing capacity test of natural quartz sand proppant should use the crushing chamber of the specified size range, see the following figure. 5. Volume density and apparent density The bulk density of the quartz sand proppant is the mass of proppant per unit volume (unit g/cm3) and reflects the overall density of the proppant stack. The main factors affecting the bulk density are the apparent density, roundness, sphericity, surface finish, etc. of the sample. The apparent density of the proppant is the mass of proppant per unit particle volume (unit g/cm3). The difference from volume density is that the volume when calculating apparent density does not include the void volume between particles. The main factors affecting the apparent density of the proppant are the phase composition, structure and porosity of the sample. For different densities of fracturing proppants, different test indexes are used. In summary, the quartz sand for fracturing has the following requirements: uniform particle size, low density; high strength, low crushing rate; high roundness and sphericity; low impurity content; wide source and low price.

Quartz sand scrubbing machine plays an important role in the mineral separation process. The mined ore is often covered by impurities such as sludge, oxides or chemicals, which affects the subsequent sorting effect and requires scrubbing and purification. At present, beneficiation plants commonly use agitating tanks and agitating rod mills for scrubbing operations. Professional quartz sand beneficiation scrubbing equipment can

[caption id="attachment_3272" align="alignnone" width="450"] Frac Sand[/caption] What is frac sand? Frac sand (fracturing sand) is high-purity quartz sand with superior pressure resistance and high roundness. This substance is artificially crushed and used mainly in the petroleum industry. Especially in the application of hydraulic fracturing, the high-pressure water pump is used to inject the fracturing fluid into the oil and gas

Silica sand beneficiation and purification Quartz sand, also known as silica sand, can be made into high-purity quartz sand after beneficiation and purification, which is used in glass, ceramics, metallurgy, casting and refractory industries. After silica sand washed by a beneficiation plant, it can meets the industry standards. Artificial sand and natural sand contain certain impurities. It is necessary to
