Hydraulic fracking technology development

Hydraulic fracking technology originated in the United States, it is the main method of shale gas exploration and development. Application of hydraulic fracturing technology can greatly improve the unconventional natural gas  production, the application of the principle is to participate chemicals into the water poured into the hydraulic fracture shale gas reservoir, thereby releasing the gas. With the large-scale commercial development of unconventional oil and gas resources, hydraulic fracturing technology must be large-scale application.

Application of oil fracturing proppant

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 hydraulic fracturing fluid mixing , using coercion injected deep cracks in the rock strata support to improve the conductivity of oil , increased crude oil production .

Hydraulic fracturing is oil and frac sand companies gas well


Hydraulic fracking is oil and gas well production and injection Wells is an important technical measures of augmented injection, not only widely used in low permeability reservoirs, and in medium and high permeability reservoirs production stimulation and good results have been achieved. It is to use the ground high pressure pumps, absorptive capacity of the viscous fluid has considerably more than the bottom displacement in injection well, don't gas pressure at bottom hole, when the time pressure is greater than the wall near the ground stress and formation rock tensile strength, the cracks near the bottom bolt. Continue to inject with ceramic proppant manufacturers carrying fluid, crack extension forward and fill with ultra lightweight proppant, closed fracture closure on resin coated silica sand, thus formed in the near the bottom of the bottom has a certain geometry dimension and flow conductivity of sand filling cracks, make to increase attention of technological measures. The principle of hydraulic fracturing increase injection mainly reduced near the bottom hole formation fluid in the change of fluid seepage and seepage resistance of state, is the original radial flow change for reservoir and the one-way flow of approximation and cracks between the wellbore and one-way flow, eliminate the radial throttling losses, greatly reduces the energy consumption. Injection and oil gas well production or injection Wells will be greatly improved. If hydraulic fracture can unicom fracture reservoir of deep oil and gas layer and gas, the increase of the effect will be more obvious. In addition, the hydraulic fracturing team near the bottom of a well damage to remove oil and gas layer is jammed.

High temperature flue gas purification with pore gradient design

High temperature flue gas purification with pore gradient design, preparation and properties of high temperature ceramic fiber membrane filtration technology is an important part of industrial emissions and environmental engineering, and high temperature ceramic ultralight weightmaterial is the core and key of high temperature liquid separation and purification. Therefore, this study based on the preparation of low filter resistance, high separation efficiency, and has good high temperature resistance, corrosion resistance, thermal shock features such as pore gradient ceramic fiber membrane, it will be on the high temperature gas such as high temperature flue gas purification treatment and environmental protection is of great significance. On the basis of the reading of resin coated frac sand amount of literature, and through the hole gradient ceramic fiber membrane using the environment requirements and preparation conditions of comprehensive analysis, design and determine the support material, ceramic fiber type and high temperature binder, the key points of the choice of pore-forming agent, and according to the high temperature dust gas particle test results and the size of the situation, determine the fiber membrane pore gradient ceramics ceramic fiber separation layer, transition layer and the pore diameter of porous ceramic membrane support matching elements. System to study the fiber membrane pore gradient ceramics with the method of preparation of porous ceramic membrane support, for the first time the heat shock casting molding process, and by adjusting the process parameters of preparation of the high temperature resistance, good thermal stability, high porosity and permeability of small resistance, high strength, large aperture cordierite porous ceramic membrane support, and study the micropore of porous ceramic membrane support performance especially aperture effect the performance of the film and film layer.

Ultra lightweight proppant has changed elastic fracturing job.

Ultra lightweight proppant has changed the ways and means of elastic fracturing job. Continue to study the unique characteristics and applications of lightweight proppants encourage people to turn to spread sand proppant volume, rather than sanding quality. Studies have shown that hydraulic fracturing proppant used ultralight
The benefits are obvious. Particle strength lightweight proppant material suitable for use as proppant, but much lower than conventional proppant products apparent specific gravity
Lightweight proppant more obvious advantages include: significant reduction in proppant settling, have increased the potential value of the effective propped fracture length; desired viscosity fracturing fluid is not high, can reduce the pump power.

Hydraulic Fracturing Proppants is increase production

Hydraulic Fracturing Proppants is increase production of oil and gas wells, injection wells by injection of an important technical measures, not only widely used in low osmotic pressure reservoir, and in hypertonic reservoir stimulation transformation also achieved good results . It is the use of advanced ground pump hydraulic fracturing benefits, high mucus has greatly exceeded the absorption capacity of the underlying displacement injection wells, in the bottom suffocating pressure, when the pressure is greater than the near wellbore formation rock to stress and tensile strength, in the bottom formation near the cracks. Continue with injected fluid carrying sand proppant, fracture extends forward and filled with proppant in the fracture closure shut the proppant to form a certain geometry and conductivity of sand filling in the vicinity of the bottom strata cracks that reach well stimulation process measures attention.

There are many kinds of fracturing fluid composition

As the case may be, the main purpose is to look at its
Packer fluid is divided into two types: the first water as a dispersion medium such as water-based  maide fracturing Proppants thickened water, gel, oil in water emulsions, water-based foam and so on are some of the acidic solution. The second is mineral oil as a dispersion medium such as

oil-based  maide resin coated frac sand fluid thickened oil, oil-in-water emulsion, oil-based foam.
Fracturing fluid performance requirements: good high viscosity, lubricity is good, a small amount of fluid loss, low friction, to be fracturing fluid layer without clogging and damage, fluid mine pollution, thermal stability and shear stability , low residue, good compatibility, broken plastic rapid, wide supply, ease of preparation, economical and reasonable.
