Abstract
The invention provides a method for manufacturing a downhole fracturing proppant by oil sludge sand, belonging to the utilization of waste materials. The technical scheme is as follows: the method comprises the steps of carrying out separation of oil, water, sludge and sand altogether on the oil-containing sludge sand, processing the separated sand in a high-temperature furnace at 800 DEG C to 1100 DEG C, screening, removing impurities, milling into 150-400meshes of powders by a Raymond mill, adding 1-3 times of amount of high-aluminum ore powder and 10-30% of iron ore, stirring uniformly to form 20-90meshes of particles; heating and drying the particles, transporting the particles into a rotary kiln, carrying out constant-speed rotation firing at 200 DEG C to 1500 DEG C so as to obtain the oil field downhole fracturing proppant. According to the method, the problem that the oil-containing sludge-sand pollutes soil and environment is solved effectively, valuable energy resource and a large amount of cost are saved, great social benefits and economic benefits can be generated, and the method is suitable for popularization and application.
Description
Technical field:
The present invention relates to a kind of method of utilizing of oily sandy sludge, especially a kind of method of using oil exploitation sludge sand making underground fracture propping agent.
Background technology:
Oily sandy sludge mainly is that the oil field produces in petroleum prospecting, exploitation; The composition of oily sandy sludge own is comparatively complicated; Contain a large amount of aging crude oil, wax, colloid, suspended solid, salt, sour gas or the like, the existence of these compositions causes under the natural condition the decompositions needs years up to a hundred fully; Oily sludge directly effluxes and can take a large amount of soils, and its toxic substance that contains meeting polluted water, soil and air worsen ecotope; At present, oil field oil-containing mud sand is put into the oily waste class (HW08 item) in " national Hazardous wastes catalogue "; (16 * 108t/a) estimations have nearly 1,000,000 tons oil sludge and sand to produce every year, and are seriously polluted, need to be resolved hurrily according to the present crude production rate of China.
Summary of the invention
The object of the invention is exactly the defective that exists to prior art, and a kind of method of using oil exploitation sludge sand making underground fracture propping agent of utilization of waste material is provided.Its technical scheme is: earlier oily sandy sludge is carried out oil, water, mud, four separation of sand; Sand after the separation is 800-1100 ℃ of laggard row filter of pyroprocessing of stove process in high temperature; Remove impurity; Grind into 150-400 order powdery with Raymond mill, add 1-3 high alumina mineral dust and 10%-30% iron ore doubly then and stir and cause 20-90 order particle; With the particle heating, drying, send into rotary kiln (200 ℃-1500 ℃) and at the uniform velocity rotate to fire and promptly can be made into the oil field and use the underground fracture propping agent.Through test, percentage of damage when its ultimate compression strength reaches 52 MPas≤5%, density is: 1.55g/cm
3-1.85g/cm
3, acid solubility＜5%-7%, product performance meet industry standard SY/T5180-2006, can satisfy the down-hole request for utilization, and this process method has realized the recycling of refuse.
Oily sandy sludge carries out oil, water, mud, four separation process of sand: oily sandy sludge gets into sand-washing device through sand pump in the pond; After sand-washing device cleaned separation, sand was disposed to the washed-out sand jar, and sand-washing device overflow sewage, sump oil, mud go back to sump oil silt particle pond and reclaims; Adding the joint station oil extraction-generated waste water in the washed-out sand jar mixes; Open the tank top whisking appliance and carry out stirring while wash, mixed sand water liquid is promoted to thickener by concentrate pump to carry out secondary cleaning and concentrates, and the sand entering concentration tank after concentrating concentrates; The thickener overflow liquid flows back to mud sand pond; Long-pending sand in the concentration tank regularly discharges, and drains into transfer roller and is promoted to vibratory screening apparatus and carries out the sand water sepn, and sewage is squeezed into the joint station waste disposal plant through sump pump and handled by the oil recovery factory.
The present invention has effectively solved oily sandy sludge contaminated soil and problem of environment, and refuse is become renewable resource, has practiced thrift the valuable energy and a large amount of funds, can have a tremendous social and economic benefits, and is fit to generally promote the use of.
