What is fracturing sand ?

Fracturing sand also is called frac sand, and fracturing sand is a kind of high-purity quartz sand, which is finely processed and has strong compression resistance and roundness. This kind of fracturing sand is often used in the field of petroleum industry as a proppant for petroleum and is an indispensable material. At present, the commonly used proppants mainly include quartz sand, bauxite ceramsite sand, etc., but compared with these materials, quartz sand is cheap and easy to pump, so it is widely used.

The petroleum proppant enters into the formation with the high pressure solution and fills in the rock fracture to support the unclosed fracture; The fracture of rock stratum will be closed due to pressure release, which will affect the production of oil and gas. After filling proppant, the oil and gas channel will be smooth, which can increase the production of oil and gas. In practical application, there are certain requirements for petroleum proppant:

1. Proppant should have strong compressive strength and wear resistance, and can effectively support artificial cracks;

2. The density should meet the requirements and be easy to pump into the well, so the relative density should be low;

3. It can not react with other substances at 200 ℃.

Because the oil in the oilfield is deep underground, with high temperature, low permeability and many fault blocks, the underground situation is very complex. The initial production of oil well fracturing is high, but the decline is also fast, and the production is unstable; At this time, the application of quartz sand proppant can effectively reduce the fracture bending friction; It can reduce the loss of fracturing filtrate into fine fractures, reduce reservoir damage and improve the construction success rate. Quartz sand proppant is mainly used for downhole support in oil fields to increase the production of oil and gas. Quartz sand is an environmental protection product and has a good effect on increasing oil and gas production.

Fracturing sand is a kind of high-purity quartz sand, which is processed through the production process of raw ore → pre-selection and screening → scrubbing → desliming → coarse particle classification → fine particle classification → magnetic separation → concentration → dewatering screen → rotary silica sand dryer → screening → finished product with pure physical and zero pollution. 

Before to classify the silica sand into different size ranges, firstly it has to be dry silica sand, then rotary silica sand dryer machine is the key sand drying equipment. 

Rotary silica sand dryer is developed from traditional rotary drum dryer, and Sunco Machinery is one professional manufacturer of silica sand dryer machine, and according to the actual need of the clients, we can design and supply the related silica sand drying machine with reasonable price and high quality accordingly.
