Abstract
A kind of mud curing agent and preparation method thereof, is characterized in that, comprise the raw material of following consumption: polyacrylamide 2%-3%, polymerize aluminum chloride 7%-8%, calcium oxide 20%-28%, Z 250 8%-15%, surplus are mud; By the polyacrylamide of 2.5%, 7.2% polymerize aluminum chloride, the calcium oxide of 24%, the Z 250 of 11% add be placed with certain water gaging grug feeding jar in stir, after medicine after dilution mixes with the mud slurry uniform in suction pit and delivers to brokenly glue flocculation reaction inner reaction tube, make slurry curing.Place in described grug feeding jar water number depend on the consumption of mud.The invention has the beneficial effects as follows, improve more than 20% than the water purification ability of conventional water treatment method, water cycle rate of utilization can be increased in sewage disposal, more can improve slurry dewatering, make mud solid-liquid separation, accelerate solid settlement, improve filtrate clarity.
Description
Technical field
The present invention relates to a kind of mud curing agent and preparation method thereof, belong to the technical field of oil field geologic drilling well aspect.
Background technology
Oil production or geological prospecting all be unable to do without drilling operation, and drilling operation environmental pollution is mainly derived from rejected well drilling liquid, if a large amount of rejected well drilling liquids does not process, may excessive inflow farmland, river or permeate the ground, the physical environment of the objectionable impurities in drilling fluid to soil, underground water and locality produces and has a strong impact on.
Summary of the invention
The object of the invention is to, a kind of mud curing agent and preparation method thereof is provided.
A kind of mud curing agent, is made up of the mud of the polymerize aluminum chloride of the polyacrylamide of 2%-3%, 7%-8%, the calcium oxide of 20%-28%, the Z 250 of 8%-15% and surplus.
The mud of the polyacrylamide by 2.5%, the polymerize aluminum chloride of 7.2%, the calcium oxide of 24%, the Z 250 of 11% and surplus forms.
A kind of mud curing agent and preparation method thereof, a certain amount of water is joined in grug feeding jar, again by the polyacrylamide of 2.5%, 7.2% polymerize aluminum chloride, the calcium oxide of 24%, the Z 250 of 11% put into grug feeding jar and stir, be delivered to brokenly in glue flocculation reaction tank by dedicated pump after mixing with the mud slurry uniform in suction pit after agitation and dilution and react, make finished product slurry curing.
The number of placing water in grug feeding jar depends on the expense of finished product mud.
The solidification of described finished product mud is divided into three kinds: A. when vehicle-mounted sludge-water separating system uses, and mixes after drug dilution with mud slurry uniform; B., when waste drilling fluids disposal system uses, after mixing with mud slurry uniform after drug dilution, glue flocculation reaction is carried out brokenly; When C. using in well site, only medicine need be put into after suction pit mix with mud slurry uniform, after carrying out brokenly glue flocculation reaction, directly solidify, landfill.
The invention has the beneficial effects as follows, improve more than 20% than the water purification ability of conventional water treatment method and can increase water cycle rate of utilization in sewage disposal, more can improve slurry dewatering, make mud solid-liquid separation, accelerate solid settlement, improve filtrate clarity.
Embodiment
The present invention is made up of polyacrylamide, polymerize aluminum chloride, calcium oxide, Z 250.
The weight percent of each raw material is:
General proportioning:
Polyacrylamide 2%-3%; Polymerize aluminum chloride 7%-8%; Calcium oxide 20%-28%; Z 250 8%-15%; Surplus is mud.
Optimum ratio:
Polyacrylamide is 2.5%; Polymerize aluminum chloride is 7.2%; Calcium oxide is 24%; Z 250 is 11%; Surplus is mud.
The preparation method of drilling well agent: first pour a certain amount of water in grug feeding jar, by the polyacrylamide of 2.5%, 7.2% polymerize aluminum chloride, the calcium oxide of 24%, the Z 250 of 11% put into grug feeding jar and stir, then the medicine after dilution by after mixing with mud in pump delivery to suction pit, again by after pump delivery to broken glue flocculation reaction inner reaction tube, make slurry curing, its state of cure is: be 1. placed on vehicle-mounted and mud and do not land in equipment and only need stir; 2. use in well site separately and need wait 40-90 minute.
Place in described grug feeding jar water number depend on the consumption of mud.
The solidification of described finished product mud is divided into three kinds: A. when vehicle-mounted sludge-water separating system uses, and mixes after drug dilution with mud slurry uniform; B., when waste drilling fluids disposal system uses, after mixing with mud slurry uniform after drug dilution, glue flocculation reaction is carried out brokenly; When C. using in well site, only medicine need be put into after suction pit mix with mud slurry uniform, after carrying out brokenly glue flocculation reaction, directly solidify, landfill.
