Description
Technical field
The present invention relates to the proppant production method, particularly a kind of high strength, high-density porcelain granule support agent and preparation method thereof of a kind of oil, the use of gasser fracturing technology
Background technology
Petroleum fracturing propping agent (ceramsite sand) is a kind of ceramic particle product, has very high pressure break intensity, 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 low strength propping agent in natural siliceous sand, glass sphere, the Metal Ball etc., and the volume increase oil and gas is had good result.
During the oil and gas deep mining, high locking pressure deposits of low permeability splits Oil gas-containing rock layer after fracture treatment, and oil gas compiles from the passage that the crack forms.Enter Filling with petroleum fracturing propping agent in rock crack in company with high-pressure solution, play support the crack not stress discharge and closed effect, thereby keep high flow conductivity, make oil gas unimpeded, increase output.Facts have proved, use the oil well of petroleum fracturing propping agent pressure break can improve output 30-50%, can also prolong 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.When product application is constructed in deep well fracturing, fill it in the rock crack in hyposmosis mineral deposit, carry out high closed fracture treatment, Oil gas-containing rock layer is split, play support the crack not stress discharge and closed, thereby keep the high flow conductivity of oil gas, not only can increase oil and gas production, and more can prolong the Oil/gas Well length of service.
In oilfield explorating developing process, especially hypotonic, special hypotonic oil-gas field, in the transformation of oil exploitation and old Oil/gas Well, pressure break has become volume increase and the Main Means that improves recovery ratio.
Propping agent is the critical material of oil/gas deep well, ultra deep well fracturing technology, plays an important role to improving oil and gas production and prolonging work-ing life oily, gas well.86Mpa percentage of damage＜10% particularly, volume density〉3.35 high strength, high-density porcelain granule support agent be external import basically.This series products mostly adopts through the bauxitic clay after the 600-1000 ℃ of roasting and makes base-material in addition, and the defective such as the adjunct ingredient that production high strength, high-density porcelain granule support agent are added is complicated, exists cost of manufacture high, and energy consumption is high, and the utilization ratio of resource is low.
Summary of the invention
The object of the present invention is to provide a kind of high strength, high-density porcelain granule support agent.
