Proppant testing becomes more important

Frac proppantis to crack open after lamination, for supporting the fracture to prevent fracture closure of a solid particle. It is an important part of hydraulic fracturing, its quality directly affects the size and the length of validity of fracture conductivity, thereby affecting the fracture stimulation effect. Thus proppant testing becomes more important
 

Hydraulic Fracturing Proppants has become the main measures of well stimulation

Hydraulic Fracturing Proppants technology has become the main measures of well stimulation, it has been widely used in the development of various oil and gas fields, of which an important part of the proppants for hydraulic fracturing, obtained many breakthroughs, especially in low permeability oil and gas development period today, proppant improve performance so that hydraulic fracturing stimulation effect increased significantly.

Ceramic ball are widely used in natural gas fracturing

Ceramic ball are widely used in petroleum, chemical, fertilizer,natural gas fracturing and environmental protection industries. As the reactor coverage tower packing proppants and catalyst. It has a high temperature high pressure, low water absorption,chemical stability characteristics. Can withstand acid, alkali and other corrosive organic solvents and can withstand temperatures occur during the production changes. Its main role is to increase the gas or liquid distribution points, support and protect the strength is not high activity catalyst.

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.
           

Kind of oil well fracking

Kind of oil well fracking

(1) hydraulic fracking, mainly by changing the state of the fluid flow, reduce energy consumption and reduce the formation of fluid flow near the lower resistance to complete. So that it can inject the proppant to achieve the diversion effect, so that the oil production.

(2) high energy gas fracturing, boosted by rapid cracks, such cracks are not easily closed during the generation of cracks naturally there will be some debris off, these chips will be self-supporting from the cracks. Meanwhile, in a high temperature wax soluble pores, resin and asphaltene, high temperature can make crude oil viscosity reduction.

(3) acid fracturing ,it is the acid as a fracturing fluid without proppant fracturing.

Fracturing technology for worldwide oil production plays a very fracture stimulation important role, while oil fracturing proppant fracturing of oil is the key to the success of the availability of technology.
High quality proppant can play an important role for the exploitation of crude oil. Oil fracturing proppant, is to maintain a deep fissure formation rock split state support. During use, the proppant fracturing fluid mixing, using coercion injected deep cracks in the rock strata support, to improve the conductivity of oil, increase crude oil production.
At present, the domestic use of fracturing ceramic, quartz sand, but their intensity is low, only for the exploitation of shallow wells. If these proppants for use in the deep, will bear enormous pressure and rock formation environment in a variety of corrosion will be a lot of broken, but prevented the outflow of oil, it is difficult to meet the requirements of the well.
Multi-sintered corundum products internationally, but to meet the requirements of this article, although the physical and chemical properties, but the sources of raw materials difficult, fracturing proppant complicated process, and the high energy consumption, high cost.
We use bauxite, together with special materials, through the laboratory, to obtain new proppant substantially achieve the desired purpose.

When oil and gas after deep mining, high closure pressure after fracturing low permeability deposit processing, the hydrocarbon formation split, passage of oil and gas from the cracks formed in the collection out bauxite proppant of the fluid injected into the rock grassroots needs at this time, to exceed the formation fracture pressure strength, so that cracks the rock around the wellbore to form a channel having a high level flow capacity, cracks formed to maintain open after fracturing oil and gas product can be smoothly passed.
         Petroleum proppant into the formation along with high-pressure solution filled in the cracks in the rock, play a supporting fracturing proppants fissure is closed not because of stress release effect, thereby maintaining high conductivity, so that oil and gas flow, increase production.
