What ceramic sand is ?

ceramic ball , is used to replace concrete gravel and pebbles , is the use of a variety of materials of various types of clay, slate , shale , coal , and industrial solid waste , etc., through the ceramic sintering.
Ceramic sand has a low density , excellent thermal insulation , impermeability, excellent alkali aggregate reactivity, low water absorption, frost resistance and good durability , and many other advantages. hydraulic fracturing proppant, by definition, ceramic particles , called fine sand , also known as oil fracturing proppant .
Most circular or oval sphere, but some ceramic imitation gravel is not circular or oval sphere, and irregular shaped gravel . The appearance of color due to different ceramic materials and process used and different. Firing ceramic colors are mostly dark red , red ocher , there are some special varieties of pale yellow , gray and black ceramic proppant sand , gray , blue gray and so on.

European shale gas storage

European shale gas reserves up to 15 trillion oil well fracking silica sand meters, showing its development has many advantages. Horsfield said the Swedish alum schist, northern Germany, the Netherlands and the south of England schist, shale are similar to the United States. European shale black or dark brown, which means rock in the formation process, the soil is rich in bio has grown organic substances, and most of these organic substances into the present shale gas. If shale storage can confirm, then shale gas will change the fate of European countries rely on Russian gas. Currently, a quarter of the EU Member States natural gas supply from Russia. ? Washington advanced energy industry consultancy Resources International (ARI) Main Coos Cora (Vello Kuuskraa) said: "The shale is the world's most abundant rock despite the lack of conventional gas resources in many parts of the world, but these places did. has abundant shale resources.

First, the hydraulic fracturing and selective

There are many multi-country oil and gas fields, usually stratified fracturing. In addition, the division of oil field development strata,proppant sand manufacturers some belong to a development strata, but reservoir heterogeneity characteristics of strong stratification exists within the layer, which is usually called oil well fracking.

1. Packer layer fracturing

Packer layer fracturing fracturing technology is a widely used at home and abroad, but the job is complicated and costly. Depending on the choice of the type of packer and the tubular string, the following four types.
1) Single-packer for the bottom layer of the hierarchical fracturing fracturing, suitable for all types of reservoirs, especially in deep and large fracturing.
2) double layer fracturing packer can open any oil and gas wells on the radio layer fracturing.
3) bridge plug packer layer fracturing.
4) sleeve packer layer fracturing

Spherical ceramic proppant

Proppant is spherical, its Ceramic proppants sphericity greater than equal to 0.8 , the apparent density of not less than 2.70g/cm3, a bulk density of not less than 1.60g/cm3. It 's the acid solubility of less than or equal 7.0% ( according to ISO9001: 2008 standard ) . It turbidity less than or equal 100FTU. Broken rate is greater than or equal 52Mpa (7500psi) next . Ceramic proppant called oil fracturing proppant . After proppant sand manufacturers deep mining in the oil and gas , high pressure low permeability deposit after closing fracturing treatment, the rock cracked petroleum , oil and gas from the cracks in the channel formed by the collection of out of the fluid injected into the rock at this grassroots needs to exceed formation fracture compressive strength , making the rock around the wellbore cracks , forming a high-level flow channel has the ability , in order to maintain after fracturing the formation of cracks in the open , the oil and gas product can smoothly pass.

Ann field fracturing sand plug factor analysis and solution

Ann profile field work area proppant sand manufacturers is the key exploration area of henan oilfield in recent years, in the south and discuss basin in biyang Zhao Ao - shed nose-like structure belt in southeast, Ann for underwater branch of fan delta front facies flow channel and front sand deposits. Reservoir geological characteristics indicate that Ann tent oilfield is characterized by deep buried depth (2 800 ~ 3 800 m), high temperature (90 ~ 140 ℃), the average permeability is 1.81 x 10-3 mu m2, average porosity of 5.2%, belong to the typical high temperature and high pressure, low porosity, low permeability fractured sandstone reservoirs. Its natural reservoir capacity is low, must be conducted by fracturing to industrial development. The formation of natural fracture development, the average fracture density is 0.57 / m, natural gas fracturing average length of 0.16 m. The existence of microcracks caused by fracturing fluid filtration, easy cause sand plug. In-situ stress and the study of the physical and mechanical properties of rocks show that Ann field horizontal maximum principal stress direction for north east 81 ￣ 93 °. Nearly east-west, level of minimum principal stress gradient averaged 0.016 0 MPa/m, high ground stress, formation fracture pressure is higher, to some extent, increased the difficulty of fracturing operation. A principle is put forward according to the geological characteristics of low damage organic boron hydroxypropyl guar water-based fracturing fluid system, the use of the linear sand and crack closure techniques such as fracturing technology

Basic Information about Ceramic proppant

Ceramic proppant is a granular product with high fracturing intensity, mainly for oilfield downhole support, to increase production of oil and gas, an environmentally friendly ceramic proppant suppliers product. This product is the use of high-quality bauxite and other raw materials, sintered ceramic, is a substitute for natural quartz sand, glass beads, metal balls and other low-strength proppant, to increase production of oil and gas have good results. When oil and gas exploration in deep, high pressure low permeability deposits closed after fracturing treatment, the rock cracked petroleum, oil and gas channel proppant sand manufacturers formed from the cracks in the collection out. Ceramic support material along with high-pressure solution into the formation filling in cracks in the rock, play a supporting fissure is closed not because of the role of stress release, thereby maintaining high conductivity, so that oil and gas flow, increase production. Practice has proved that the use of ceramic proppant fracturing wells can increase yields by 30-50%, but also to extend the service life of oil and gas wells. 

From the international fracturing proppants environment the ongoing transfer of industries

From the international environment, first, the ongoing transfer of industries in Western countries, China is facing a good opportunity to become the world's manufacturing center. Second, the international oil prices continued to rise, stimulating investors have the funds natural gas fracturing to invest in oil exploration and development and oil processing, the formation of a new round of oil investment peak surge in demand for ceramic proppant. Our ceramic proppant products cost-effective than some developed countries, has a comparative advantage. Third, the three major oil companies are vigorously implement the "going out" strategy to accelerate overseas business development, can stimulate domestic oil proppant into the international market. These are for export and development of large enterprises ceramic proppant provides a rare opportunity. However, the development of ceramic proppant industry is also facing serious challenges. With

international ceramic proppant suppliers prices continued to rise and continued tight supply of oil and gas, oil and gas exploration and development investment continued to increase the pace of energy such as oil and gas pipeline infrastructure continues to accelerate, substantial growth in demand for ceramic proppants, which also attracted a large number Investors have entered, intensified market competition.
