Description
Technical field
The invention belongs to inorganic non-metallic ceramics Material Field, be specifically related to a kind of low-density ceramic proppant utilizing coal ash for manufacturing standby and preparation method thereof.
Background technology
Petroleum fracturing propping agent (ceramsite sand) is a kind of ceramic particle product, has very high fracturing strengh, is mainly used in oil field well and supports, and to increase the output of oil and gas, belongs to environmentfriendly products.This product is the substitute of the Medium and low intensity propping agents such as natural siliceous sand, glass sphere, Metal Ball, has good result to stimulating oil Sweet natural gas.
During oil and gas deep mining, high locking pressure deposits of low permeability, after fracture treatment, makes Oil gas-containing rock layer split, and oil gas collects from the passage of cracking initiation.Enter Filling with petroleum fracturing propping agent in rock crack in company with high-pressure solution, play and support crack not stress release and closed effect, thus keep high flow conductivity, make oil gas unimpeded, increase yield.Facts have proved, use the oil well of petroleum fracturing propping agent pressure break to improve output 30-50%, can also extend the Oil/gas Well length of service, is the critical material of oil, the exploitation of Sweet natural gas low-permeability oil gas well, construction.Product application is when deep well fracturing is constructed, fill it in the rock crack in hyposmosis mineral deposit, carry out the closed fracture treatment of height, Oil gas-containing rock layer is split, play support crack not stress release and close, thus keep the high flow conductivity of oil gas, not only can increase oil and gas production, and more can extend the Oil/gas Well length of service.
Propping agent density is divided into three kinds by usual people custom: low density, Midst density and high-density, is generally 1.65 g/cm respectively with volume density and volume density
3below and 3.0g/cm
3hereinafter referred to as low-density propping agent; 1.65 g/cm
3~ 1.80 g/cm
