Demand-driven development of ceramic proppant

Demand-driven development of ceramic proppant
Shale gas development boom to increase demand for ceramic proppant
Global shale gas reserves are abundant, diversified energy supply pattern indicates that the goal will usher in a wave of a larger global shale gas and other unconventional natural gas boom. Shale gas than conventional gas recovery is low, the demand for  Ceramic proppant  greater. Ceramic proppant compared with quartz sand and resin-coated sand  proppants have higher permeability and resistance to stress, studies have shown that use of ceramic proppant can improve oil recovery, increase production, to extend the life of oil and gas wells, high-end pottery proppant grains cost is even higher.
Ceramic proppant production line is mainly caused by broken, ingredients, grinding, ball, calcination, coal preparation, finished cooling, screening and other processes, the main use of the equipment crusher, sand making machine, vibrating screen, mills , biaxial mixer, granulator, rotary kiln, coal feeder, cooling machines and other equipment, the main raw materials used for the bauxite.

ceramic proppant quality decision oilfields
Hydraulic fracturing technology, the fracturing materials are the key aspects of fracturing a ring, and fracturing the quality of materials is a key safeguard the quality of construction, fracturing material can safe, timely security for, is to determine an oilfield production priority. Ceramic proppant crushing rate detection key indicators, the standard is ≤ 7%.
1940 without  Proppant  fracturing test, because poor performance without proppant fracturing stop soon. 1950 Early fracturing using quartz sand from the Arkansas River and the state of Illinois Ottawa's Saint Peter formations "White" quartz sand. 1958 Brady near Hickory sandstone with "Brown" quartz sand. 1960 glass beads, plastic beads, walnut shells - try sanding layer design, as settlement, embedding, stress concentration and failure (soluble proppants spacers). 1970-1975 curable resin wrapped quartz sand. 1979 The first commercial ceramic proppant. 1980-1982 pre-cured resin wrapped quartz sand. 1985 low density ceramic, porous support additive agents; such as adding inhibitors to prevent the scale of certain ceramic products increased strength and a more narrow particle size distribution. 2002 very low density ceramic proppant success.
