ultralight weight Fracturing fluid

Fracturing fluid

Fracturing fluid is the fluid mine (gas, steam, oil, fresh water, salt water, hot water, etc.) in the mining process, in order to obtain high yield and borrow liquid conduction force (such as hydro, etc.) used in fracturing fluids.

Fracturing fluid is divided into two types: the first one is water as a proppant suppliers dispersion medium such as water-based fracturing fluid thickened water, gel, oil in water emulsions, water-based foam and certain acidic solution and so on. The second is mineral oil as a dispersion medium such as oil-based fracturing fluid thickened oil, oil-in-water emulsion, oil-based foam.

2 Features

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.

Hydraulic fracturing is a process oil in a large displacement of the ground using high pressure pump, the pressure of the pressure transmission principle using a liquid, the liquid having a viscosity (usually called fracturing fluid) to be greater than the absorption capacity of the oil reservoir injection, and to gradually increase the pressure in the wellbore, which hold the bottom from the pressure, when the pressure is greater than the ultralight weight near wellbore formation rock to stress and tensile strength, it cracks near the bottom strata: Continue injected with with the proppant sand carrying fluid to fill the crack extends forwardly proppant in the fracture closure shut the proppant to form a sand-filled fracture geometry and having a high conductivity in the vicinity of the bottom of the formation, is well to increase production by injection purposes. Which is also known as proppant fracturing fluid. Fracturing fluid can be divided into: A water-based fracturing fluids (water fracturing fluid thickener, water gel fracturing fluid, oil in water fracturing fluids, water-based foam fracturing fluid); B oil-based fracturing fluid ( thickened oil fracturing fluid, oil gel fracturing fluid, oil-in-water fracturing fluids, ceramic proppant manufacturers oil-based foam fracturing fluid). C emulsion fracturing fluid; D pure gas fracturing fluid 

Introduction Coalbed Methane

Coalbed methane commonly known as "gas", whose main ingredient is CH4 (methane), associated with coal, [1] to the adsorption state stored in the seam unconventional natural Hydraulic Fracturing Proppants gas calorific value is 

Universal Coal 2-5 times, mainly composed of methane. Net calorific value of 1 m3 of coalbed methane gas equivalent to 1.13kg, 1.21kg of coal, and natural gas calorific value rather 

Can be mixed with natural gas output mix, and very clean combustion, [2] virtually no emissions, is a good industry, chemical industry, power generation and residential fuel 

Material. When the CBM air concentration up to 5% -16%, in case of fire will explode, which is the root cause of coal mine gas explosion. Coalbed methane emitted directly into the proppant suppliers atmosphere, which 

Approximately 21 times the greenhouse effect of carbon dioxide on the ecological environment devastating. If coal mining before the first coal bed methane, coal mine gas explosion rate will be reduced to 70% 

To 85%. Development and utilization of CBM has multiple purposes efficacy: clean energy, commercialization can produce huge economic benefits. 

National development policies 

National Energy Board issued "CBM industry policy," the silence want to change the momentum of development of coalbed methane, coal-bed methane industry to clean up institutional barriers will send the CBM industry 

Exhibition has become an important emerging energy industry. 

Degree of attention from the national perspective, the CBM has been incorporated to promote an important carrier of energy production and consumption revolution. Energy Board proposed development objectives are: "Twelve Five" period 

Rooms, built in Qinshui basin and the eastern fracturing fluid edge of the Ordos Basin coal-bed methane industry base. Then 5-10 years, 3-5 new industrial base, to achieve the CBM open
