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

For oil fracturing proppant mixer granulator

According to the resulting pellet size, density and wet conditions, mixing granulator can generally be divided into two categories. Like horizontal mixing tank and kneading machines of the first type, in this type of granulator, generally in a capillary state can create dense pellets, rolling pan granulation method similar products. Class mixer or blender to produce a strong internal component friction and shearing. Mixing granulation method is superior than the roll pan granulation method, because it has a kneading action that can create high hardness, high strength pellets, capable of handling viscous materials, to changing operating conditions have a greater ability to adapt. Mixed method were relatively dense pellets, liquid dosage required is less than its roll pan granulator. Disadvantages mixing granulator, usually a larger maintenance costs and power consumption, the irregular shape of the product, you may need further shaping, such as the application roller tray dryer so that the product is regular in shape.
The second class of mixed granulation method, the degree of wetting of the powder into the capillary state far, aggregate strength of the formation of relatively poor production of "instant" food wetting balance, drying and cooling process, that is such a granulation for example.
These two categories are mixed granulation equipment development, however, some types of mixers for granulation method are applicable. Distinction between granular and dense instant granulator granulator between large grains, some arbitrariness, are some examples:
1. Horizontal disc mixer
In the early ceramic sand granulation, horizontal disk-shaped mixer mixed with granulation Hydraulic Fracturing Proppants into one, the typical horizontal disc granulator, diameter up to 7.5ft (2.3m), deep 18in (0.5m) , material capacity of from 0.5 to 1t (0.5 to 0.9mg). Eccentrically mounted disc and the disc in the reverse tumbling mixing blades, to maintain a certain state of agitation, along with a plasticizer (e.g. water) is injected, they formed a dense pellet. For ceramic sand granulation, the mixing time is typically 2 or 3 minutes, automatic circulation system, its production rate is generally 12 to 15t / h (11 to 14rmg / h), but up to 30t / h (27mg / h) are also possible. In modern ceramic sand granulator industry, such a mixer (for example Eirich mixer rotating disc-shaped horizontal convection) is typically used for the swash plate granulator feed.
2. Blade mixer
Also known blender blade mixer, paddle mixer, and kneader. Usually consists of horizontal trough and mounted on the inside of the agitator shaft. In the stirring shaft equipped with a rod, needle-shaped, plate-shaped stirring blades and other forms. The stirring tank can be a uniaxial type, a biaxial type or may be, but generally the most common two-shaft. Two counter-rotating shafts, shaft intermeshing hydraulic fracturing proppant paddle into the front and center of the material. Thick frame and impeller blades from the edge of the member or the composition, structure and firm, hard edge portion. Can be attached to the exhaust hood, spray systems and the use of stainless steel components. In addition to feeding the mixer end portion estuary, the charging port may be provided at any position along the length of the mixer, can be applied to a total length of the mixer, the mixer operation more flexible.

Oil fracturing proppant equipment

The rapid development of the world oil industry, oil and gas extraction difficulty is gradually increased, the depth of oil and gas wells deeper, low permeability type deposits are also more and more domestic and international demand for high strength  Maide fracturing proppant  products volume is also growing.
Oil fracturing proppant production process equipment to meet the requirements of oil fracturing  fracturing proppants  products. Produce anti-fragmentation of 53Mpa and 69Mpa conventional products, and produce anti-fragmentation of 86MPa and 102Mpa products, grain diameter of 0.2 ~ 0.9mm, in full compliance with Q/SH0051-2007 standards.
Oil notable features  isp proppant  production lines are:
1, rational layout, process flow, high degree of automation;
2, mechanized joint control operation, low labor intensity;
3, calcination parameters real-time monitoring, firing good quality product;
4, producing energy than good, low running costs.

Oil proppant market forecast

Is expected in the next few years, our country oil fracturing proppant industry market size will rapidly expand, total output of enterprise can also increase quickly. Oil fracturing proppant supplier product development in the direction of the high strength. And the products will be toward more subdivided the trend of development, will further enrich product series. Oil fracturing proppant products in China market will get fast development, the annual growth rate over 27%. Is expected in 2012 oil fracturing proppant supplier products market scale growth at 29.23%, the size of the market in 2.74 million tons. 

Shale ceramic ball

Can be used as a gas source rocks and reservoir rocks and reservoir has a continuous distribution , low porosity and low permeability ultralight weight , high brittleness and other characteristics. Shale gas in three forms: free gas in rock pores , natural fractures in the free gas and adsorbed gas upbraid these different organic mineral surface oil well fracking mechanism directly affects the way shale gas development , speed and efficiency.
Global Energy Studies estimates that large shale gas resources are mainly distributed in North America, Latin America and Asia Pacific. 2012 study showed that the U.S. shale gas resources of approximately 415 000x10 ^ 520 000 qe 108 V, Canada, approximately 140 000x10 ^ 170 000x10 ^ ^ 3, China's major shale gas basins and large areas of recoverable resources of approximately 260 000 qe 108 V, while the resource situation in other parts of research is very limited.
Experience shows that U.S. shale gas development : increase the level of technology especially well fracturing technology [ 1 ] , for shale gas development is vital, other important technologies, including directional drilling horizontal wells and reservoir description .
