Name:Proppant Introduction
Item:12-20,16-20,16-30,20-40,etc
Description:

Ceramic proppant is a kind of product made of ceramic granules, it has high fracture intensity. It is mainly used for sustaining down hole in order to increase the output of oil and gas. It is annual consumption product, so lots of proppant will be injected in the following year. This product is produced by many kinds of raw materials, such as bauxite, manganese powder, etc. It is sintered by ceramics and it is better than natural quartz sand, crystal ball and metallic ball which are low intensity or medium intensity. It is good for the increment of oil and gas. In brief, The production of petroleum ceramic proppant has many processes, such as crushing, dosing, grinding, ball forming, burning, cooling, sieving, packing and so on. Its main material is high-grade bauxite.
Self-developed 52Mpa, 69Mpa, 86Mpa low, medium and high intensity proppants are high technology products. After special grinding, balling and high temperature sintering, the products have many characteristics: high temperature resistance, high pressure resistance, high intensity, good conductivity and corrosion resistance. Ceramic proppant is a good helper for oil and gas exploration.

Types of proppant:
Crushing limit:52Mpa(7500psi),69Mpa(10000psi),86Mpa(12500psi) b. Volume density:Low density, Medium density, High densityc. Specification:12-20,16-20,16-30,20-40,30-50,40-70,40-80,70-140 and so on,our company is researching and developing different intensity and specifications products in order to satisfy the demands from domestic and overseas.

Ceramic proppant Advantages
The advantages of ceramic sand: ceramic proppant has high performance density. Under the same closure pressure, compared with quartz sand, it has the performance of low broken rate and High flow conductivity. Especially in the high closure pressure can provide a certain amount of diverting capacity, complete fracturing of the production tasks.
Ceramic proppant has the performance of salt resistant, high temperature resistant in 150 ~ 200 ℃ containing 10% salt water aging after 240 h. The compressive strength is constant,under the conditions of 280 ℃ and PH value of 11 . aging after 72 h, Ceramic weight loss of 3.5%, but about 50% quartz sand was dissolved.
With the increase of closure pressure and Extension of time pressure-bearing,The broken rate of Ceramic is much lower than the quartz sand. Diverting capacity decline rate is slower. So, For any depth and any reservoir, Using ceramic proppant, hydraulic fracturing will be higher at the beginning of production, Stable production and longer validity.
Results
It has been proven that Ceramic proppant can increase 30%-50%  productivity, and it can also extend the oil and gas service period.
