What are the raw materials of ceramic sand production
Maide ceramic proppants is that we can not live without product , because of the presence of ceramic sand , our life more colorful . Ceramic sand then you know what are the raw materials to produce it? We just did not put that garbage on the location of another resource , for example, living on garbage , which can be processed to produce a high-quality ceramic sand . In fact, the raw materials to produce ceramic sand there are many .
For example, also can produce ceramic slag sand , slag activity is relatively high, but due to a large set of slag has been used in cement production , so the current tight supply . Except slag , fly ash, coal slag and natural or calcined higher activity waste rock , these three waste emissions from large , ample supply , easy to find everywhere , should become the subject of Maide high density ceramic production unburned material . relatively few other tim of waste, can be adapted to local conditions to choose from.
Different active material and cement , the cement hydration can directly produce cementitious material, and it is the first active material and the reaction of calcium hydroxide , then water, into the gelatinous substance . But even so , the activity of the active material is also of value , but also for reducing the cost of ceramic sand is very meaningful. So, if there is such a source , then the slag , or try the first choice .

Performance oil fracturing proppant
The role of oil fracturing proppant (Fracturing Proppant) that separates the two wall cracks and effective support , so that always cracks after fracturing can be effectively supported , thus eliminating most of the radial flow formation , formation fluids to linear flow way into the cracks. Usually require fracture permeability than the formation permeability several orders of magnitude . Understanding the type of proppant and closed in the state under stress , performance evaluation and Hydraulic Fracturing
Proppants to support a variety of factors influence fracture conductivity is the correct choice and use of proppants foundation.

Application of oil fracturing proppant
Maide fracturing
fluid technology is an important means to transform oil and gas fields , it is the use of artificial methods of fluid injected into the rock of the grass-roots level to exceed the strength of the formation fracture pressure , so that cracks around the wellbore rock layers , forming a channel with high conductivity . In order to maintain open after fracturing the formation of cracks , oil and gas products through smoothly , injecting particulate proppant is one of the important measures.
Fracturing technology for worldwide oil production plays a very important role, but oil is a key oil fracturing proppant fracturing technology can be successful . High quality proppant can play an important role for the exploitation of crude oil. Oil fracturing proppant , is to keep the fractured rock formations deep split state support , particle size 0.2-0.9 mm, there is a certain roundness and sphericity . During use , the proppant Maide hydraulic fracturing fluid mixing , using coercion injected deep cracks in the rock strata support to improve the conductivity of oil , increased crude oil production .
At present , many domestic use fracturing ceramic, quartz sand , but their strength is low , only for shallow wells with . If these proppant use in deep well , will bear great pressure and rock formations in a variety of corrosive environments , will be a substantial crushing, crushing rate is generally 15% -25 % , but prevents the outflow of oil , it is difficult to meet the wells requirements. International ( such as the U.S. ) to use more sintered corundum products , but to meet the requirements of this article although the physical and chemical properties , but the sources of raw materials difficult , complicated process , and energy consumption, and high cost .

How to select fracturing proppant
According closure pressure to fracture the formation of the election, a large compressive strength proppant to support level is greater than the closing pressure of the formation.

High-performance ceramic sand and their use
The reason why the particles have developed rapidly in the world, because it has other materials do not have a lot of excellent performance, this excellent performance, the excellent performance it has the effect of other materials can not be replaced. These excellent performance in the following areas.
Density, light weight.
The ceramic itself is less than the bulk density of 1100kg/m3, generally 300 ~ 900kg/m3. As aggregate in the production of Hydraulic Fracturing Proppants density of 1100 ~ 1800kg/m3, corresponding concrete compressive strength of 30.5 ~ 40.0Mpa. The biggest feature is the appearance of a hard ceramic, but there are many internal pores. These pore-forming properties of lightweight ceramic. No. 200 Lytag concrete density is about 1600kg/m3, and the density of ordinary concrete is up to the same label 2600kg/m3, a difference of 1000kg/m3.
