Abstract
The invention relates to a sludge particle water plugging agent. The water plugging agent is produced by performing the processes of drying, crashing, sorting, granulating, coating, packaging and the like on oil field sludge. The sludge particle water plugging agent is composed of spherical particles, has the particle size of 1 to 8 mm, and is suitable for plugging channels with different sizes. The sludge particle water plugging agent has a multi-layer package structure which takes a spherical nuclear as a center; a package layer consisting of a plurality of layers of sludge powder and an adhesive is formed outside the spherical nuclear; a thin water-proof anti-erosion protective layer is formed on the outermost layer. When the sludge particle water plugging agent is applied to construction, water or a diluted polymer solution serves as carrying liquid, the sludge particle water plugging agent is accumulated to form plug at a channel after entering stratum, and when the sludge particle water plugging agent is accumulated to a certain degree, the pressure rises, and high-strength plugging is formed under an leak-off effect. Plugging and profile control effects are controlled by selecting construction carrying capacity, and the concentration and the particle size of the sludge particle plugging agent. The sludge particle water plugging agent manufactured by oilfield sludge belongs to an inorganic water plugging agent, the plugging strength is high, the manufacturing method is simple, and the effects of changing waste into wealth and protecting environment are achieved.
Description
Affiliated technical field:
The present invention relates to a kind ofly utilize particle plugging agent that oil field output mud manufactures for oil field profile control, water blockoff measure, be applicable to oil field sludge re-injection and oil field sludge profile control, water blockoff increase oily measure.
Background technology:
Organic plugging agent and inorganic plugging agent are divided with plugging agent in oil field, and organic plugging agent mainly takes organic materials rely on to improve the viscosity of plugging agent and duct, the stifled stratum of the distortion transport characteristics of particle, reaches the object of profile control, such as polymkeric substance etc.; Inorganic plugging agent mainly utilizes inorganics precipitation to stop up and inorganics solidifies obstruction, such as receiving soil, cement etc.Oil field sludge is the waste in oil field oil water treating processes, with method for sludge treatment, be now: the mud mud magma that a kind of Shi Ba oil field produces is moved water injection well well site to tank car, with surface pump re-injection, enter underground again, because mud all produces every day, pump into construction successively, processing cost is high, pollutes stratum, and oil increasing effect is poor.Another kind is to form dewatered sludge and leave that stock ground cannot utilize, pile up like a mountain in pressing mud machine to extrude sludge slurry moisture.Environmental administration requires pollutent not shift, and can only wait for re-injection.Utilize the particle plugging agent of oil field association output mud manufacture to belong to inorganic plugging agent, its manufacture method is simple, can play the effect of turning waste into wealth.
Summary of the invention:
The object of this invention is to provide a kind of mud granule plugging agent, this plugging agent utilizes oil field sludge to produce through operations such as oven dry, pulverizing, sorting, granulation, dressing, packings.Its profile is spherical granular, and particle diameter is the duct that 1-8mm is applicable to the different sizes of shutoff.Its structure is multilayer package structure centered by ball; Its ball can adopt rubber grain, fine perlite etc. can adjust the proportion of particle; Ball is outward that multilayer mud powder adds the integument that tackiness agent forms, and tackiness agent adopts water or rare polymers soln; Outermost is the protective layer of the waterproof antiscour that one deck is thin, can adopt gypsum bisque or organic membrane.Its composition is mainly the contained clay mineral of oil field sludge, water conditioner and a small amount of greasy dirt and polymer binder.This mud granule plugging agent is being executed utilization of hour water or rare polymers soln as transport fluid, enters place, Hou Hou road, stratum and piles up to form and stop up, and when accumulation acquires a certain degree, pressure raises, and forms high strength shutoff considering under mistake effect.By the selection of construct carrying capacity and mud granule plugging agent concentration, particle diameter, control shutoff and profile modification.
Embodiment:
The sludge slurry that oil field produces is through pressing the mud machine formation dewatered sludge that squeezes the water out, through Exposure to Sunlight efflorescence or oven dry, enter wind sorting equipment, the large diameter grains of sand can be used as construction material, other powdery, finely powdered dewatered sludge enter facility for granulating, by spraying a small amount of tackiness agent, under the effect of wind-force, mechanical rotation, produce a certain size circular granular, then preserve after drying.Select oil field to need the oil and water well of water blockoff, leak stopping, profile control, utilize water or rare polymers soln as transport fluid, this mud granule plugging agent is injected to place, Hou Hou road, stratum and pile up to form and stop up, when accumulation acquires a certain degree, pressure raises, and under worry mistake effect, forms high strength shutoff.By the selection of construct carrying capacity and mud granule plugging agent concentration, particle diameter, control shutoff and profile modification.Adopt surface pump that the dry particle of a certain proportion of mud is pumped in well together with water, the amount pumping into, the concentration of dry particle, injection pressure and speed can be determined according to construction object.
