Ceramsite Petroleum Fracturing Proppant For Oil Field Mining
Machine Spare Parts
1. Introduction of proppant products for oil field fracturing mining machine spare parts
At present, the commonly used proppants mainly include quartz sand,
aluminum-vanadium clay sand and resin coated composite particles.
Quartz sand is widely used because of its low cost, low density and
easy to pump, but it is not suitable for deep Wells with high
closure pressure because of its strong bottom and poor sphericity,
which reduces fracture conductivity. Resin coated compound
particles of quartz sand, sphericity is improved and corrosion
resistance is strong, diverting capacity is better also, retention
period is short, but the product cost is too high, the cost of
today's promotion is not easy, and adopts aluminium vanadium and
soil in the process of ceramsite ceramsite proppant, high density,
good sphericity, corrosion resistance, high temperature resistance,
resistance to high pressure, the cost at the same time be able to
get good control, Therefore, more and more widely used by oil and
gas fields. Practice has proved that the use of ceramsite proppant
fracturing oil Wells can increase production by 30-50%, but also
prolong the service life of oil and gas Wells. It is a key material
for the exploitation and construction of low permeability oil and
gas Wells, which can not only increase oil and gas production, but
also prolong the service life of oil and gas Wells.
2. Performance requirements of petroleum proppant mining machine spare parts:
(1) The proppant must have sufficient compressive strength and wear
resistance to withstand strong pressure and friction during
injection and effectively support artificial fractures.
(2) The relative density of proppant particles should be low to
facilitate pumping downhole.
(3) Proppant particles do not chemically interact with fracturing
fluids and reservoir fluids at a temperature of 200 degrees, and
the maximum allowable acid solubility should be less than 7%.
3. Proppant product parameters for petroleum fracturing mining machine spare parts
The petroleum fracturing proppant produced by our factory has high
fracturing intensity and is mainly used for downhole support of oil
field to increase the output of oil and gas. It is an environmental
protection product. This product makes use of high-quality bauxite
and other raw materials, sintered with ceramic, natural quartz
sand, glass ball, metal ball and other medium and low strength
proppant substitute, has a good effect on increasing oil and gas
production. In the exploitation of deep oil and gas Wells, the high
closed pressure and low permeability ore deposits are fractured and
the oil and gas come out from the channels formed by the fractures.
The ceramsite support material along with the high-pressure
solution is used to enter the formation and fill in the rock
fissures, which plays a role of supporting the fissures without
closure due to stress release, so as to maintain high conductivity,
make oil and gas smooth and increase production. It has been proven
that Wells fractured with ceramic proppants can increase production
by 30-50% and extend well life. Proppants can be widely used in
deep Wells and high-pressure oil and gas reservoirs. High quality
bauxite as the main raw material by crushing fine grinding into
powder, with a variety of additives, repeated mixing, granulation,
polishing. Sintered at high temperature, the product has the
advantages of high compressive strength, low density, good
sphericity, high finish, strong conductivity and so on. According
to the test of support evaluation Laboratory of Langfang Branch of
PETROCHINA Research Institute of Petroleum Exploration and
Development, all performance indexes fully meet the standards of
SY/T5108-2006 and SY/T6302-1997, which are in the leading level at
present.
(1) According to the crushing resistance of 52MPa(7500psi),
69MPa(10000psi) and 86MPa(12500psi), 102MPa(15000psi) four series.
(2) According to the volume density, it can be divided into low
density, medium density and high density.
(3) According to specifications :12-20 mesh, 16-20 mesh, 16-30
mesh, 20-40 mesh, 30-50 mesh, 40-60 mesh, 40-70 mesh, 70-100 mesh,
etc.
In order to meet the needs of domestic and foreign oil and gas
Wells, users can choose different strength and different
specifications of products according to the depth of the oil well.
