Abstract
The invention relates to a method for preparing an elastic particle flooding/profiling agent. The method comprises the following specific operating steps of: mixing oily sludge with a polymerization monomer, an initiator, a crosslinking agent and water; performing a polymerization crosslink synchronous reaction to generate an elastic rubber block; and cutting, granulating and sieving the elastic rubber block to obtain elastic particle flooding/profiling agents of different particle diameters. In the method, oilfield oily sludge can be directly taken as a filler for preparing an elastic particle flooding/profiling agent. The elastic particle flooding/profiling agent can be used for absorbing water by 3.5-12 times, and expands for 5-15 days; after water absorption, the elastic modulus and yield stress are higher than 6KPa, which are over two times that of an original expansion particle material; and the elastic particle flooding/profiling agent is a high-strength elastic gel, has high deep placement, deformation and blocking properties, can be taken as an oilfield gel particle flooding/profiling agent, and contributes to environmental pollution and lowering the oilfield production cost.
Description
Technical field
The present invention relates to a kind of elastic granule adjusting driving agnet preparation method, belong to the Oilfield Chemicals synthesis technical field, especially utilize oily sludge to prepare elastic granule adjusting driving agnet technical field.
Background technology
Sludge in Oilfields is a kind of solid waste that produces in oil production and disposing polluted water in oil process, and output is large, complicated component, and it is difficult to process, and is one of important pollutent that affects oil field and surrounding enviroment quality.According to incompletely statistics: the annual oily sludge nearly 1.43 * 10 that produces of Daqing oil field
5m
3, the annual oily sludge nearly 1.0 * 10 that produces of Shengli Oil Field
5m
3, the annual oily sludge nearly 1.5 * 10 that produces of Dagang Oilfield
5m
3, the annual oily sludge nearly 5 * 10 that produces of Henan Oil Field
4m
3, the annual oily sludge nearly 8.76 * 10 that produces in Zhongyuan Oil Field
4m
3, and generation rises year by year.Oil gas volatilization in the oily sludge makes the interior Air quality of output zone exist total hydrocarbon content to exceed standard; The oily sludge polluted surface water even the polluted underground water that are scattered and stack make COD in the water, BOD and petroleum-type severe overweight; Substantial oil in the oily sludge causes Land pollution, and petroleum-type exceeds standard and makes soil compaction, and regional implants is destroyed, and ecotope is affected.
The method of disposal and utilization oily sludge mainly contains both at home and abroad at present: utilize the characteristics that oil-contg is high in the oily sludge to produce reclaimed coal, with a certain proportion of oily sludge (10%～30%), coal dust (60%～80%), other composition (5～10%) through mud concentrate, flocculate, dewater, mix, the technique such as extrusion molding, oven dry makes reclaimed coal, this method can accomplish to make mud " minimizing, innoxious and resource utilization " but complex process, input cost is high, and the mud utilization ratio is lower, still has solid waste after the burning; Utilize oily sludge to produce material of construction, oil field sludge after the desalinization of soil by flooding or leaching, oil removing dehydration, is added in proportion certain solidifying agent, filler and cement and is cured, the method pre-treatment is complicated, and processing costs is high, and investment cost is high, floor space is large, may cause secondary pollution after the curing; Utilize oily sludge as amendment, mud is injected reservoir, utilize solid particulate to stop up the rock core duct, make follow-up injected water change seepage direction, improve the injected water swept volume, the method can't be used macropore or extra-high-speed infiltration oil reservoir, simultaneously owing to solid grain size narrow range in the mud, contain former Chuck Steak, plugging strength is low, and validity period is short, in may polluting in the injection process, low permeability layer; CN1781860 method of utilizing oil exploitation sludge to prepare volume expansion type granular profile control agent, with the swollen gel particle of preparation water behind the oily sludge hot water pickling degreasing, the crude oil cost that the method need to be removed in the oily sludge drops into larger; To bury or burn after the oily sludge dehydration, the method have not only wasted resource, but also has polluted the landfill yard surrounding enviroment; Adopt solvent extraction, high temperature or catalytic cracking to process the oil that extracts in the mud, the method needs a large amount of equipment investments, and the mud after the processing can only waste treatment; Biotechnology is processed, and can administer the pollution in wide area that oily sludge causes, but last length, and oily resource can't be recycled; CN1781860 discloses a kind of method of preparing rubber filler with oil-bearing sludge, at first oily sludge is pulverized separation, rejects the above particle of 200 orders, then carries out wet grinding, makes the powder granule particle diameter reach D
50≤ 3.0 μ m, D
90≤ 6 μ m, powder slurries after the grinding are after dehydration, water ratio is less than 40%, and is then dry to cake scattering, makes its water ratio less than 0.4%, sieve with screening plant, obtain the following powder of 200 orders, obtain the oil-containing packing agent, the method pre-treatment is complicated, investment cost is high, and floor space is large.
Owing on treatment process, also there being many problems, most of oil plays still adopt behind the natural drying direct landfill or build the mode that storage pool deposits temporarily and process, not only pollute the landfill yard surrounding enviroment, but also wasted the petroleum resources in the oily sludge.
