Embodiment 2:
Present embodiments provide a kind of breaking glue solution, the component including following weight portion mixes:
Coagulant: 20%
Flocculant: 2.5%
Solid-liquid separating agent: 3.0%
Water: 74.5%
Wherein, described coagulant is the mixture of polyaluminium sulfate and polymeric aluminium ferrum silicate, polyaluminium sulfate and polymerization silicon
For 3:2, polyaluminium sulfate and polymeric aluminium ferrum silicate all can be buying on the market, and polyaluminium sulfate is mark for the weight of sour ferro-aluminum ratio
The high-quality product that quasi- gb14591-93 specifies.
Described flocculant is expoxy propane, oxirane, the copolymer of acrylamide, expoxy propane, oxirane, propylene
The weight of amide ratio is for 1:1:3, and this molecular weight of copolymer is 10,000,000, and described solid-liquid separating agent is carboxymethyl-acrylic-amine
Base modified cellulose sodium salt, described expoxy propane, oxirane, the copolymer of acrylamide and carboxymethyl-acrylic-amido change
Property cellulose sodium salt by engineering and technological research institute of Chuan Qing drilling project company limited provide it is also possible to directly buy from market.
This breaking glue solution is carried out with performance evaluation:
First, break glue, take off steady performance evaluation:
With 67.6% water+3% bentonite+0.4% high adhesive aggregation anionic cellulose sodium salt+0.5% Caustic soda+1.5% sulfonation
Asphalt powder+1.5% sulfonated phenol formaldehyde resin+0.5% sulfonation tannin+25% barite prepares low solid phase sulphonated polymer mud base slurry,
Add this breaking glue solution according to different dosages in base slurry, the broken glue of observed and recorded base slurry, delamination, in experiment using broken glue rate,
Separate out water and api dehydration characterizes the broken glue degree of base slurry, data result is as shown in table 1.
Table 1 breaks glue situation
As it can be seen from table 1 with the breaking glue solution dosage of the present embodiment to 5.0% it is possible to this is discarded low solid phase polysulfonate
Drilling well liquid-based slurry thoroughly takes off steady, broken glue, and solid-liquid is substantially layered, and broken colloid is solid to be in granular form, and using the existing centrifuge of drilling team, shakes
Solid-liquid separation just can be continuously added brokenly glue rate and is deteriorated on the contrary by dynamic sieve, and reason is as the excess addition of breaking glue solution, broken colloid by
Step dispersion, clear liquid viscosity also increases after breaking gel, and broken glue rate reduces.
This low solid phase sulphonated polymer mud base is starched through breaking glue solution after breaking gel, is carried out using drilling crew's centrifuge or vibrosieve
Solid-liquid separation, is contrasted to the property of drilling fluid before and after solid-liquid separation, is shown in Table 2.
Table 2 base slurry is contrasted with the liquid phace property after solid-liquid separation
Remarks: fv is funnel viscosity, and fl is middle pressure dehydration, and av is apparent viscosity, and pv is plastic viscosity, and yp is yield value,
Ph is acid-base value.
From table 2 it can be seen that low solid phase sulphonated polymer mud base slurry is after broken glue, separating treatment, there is the change of matter in performance
Change, density, viscosity are greatly lowered, and rheological characteristic thixotropy is completely destroyed, and the liquid phace property after solid-liquid separation is essentially close to
Clear water, the liquid phase volume of generation is the 55% of base volume of slurry, volume half, and the control amount being especially advantageous for rejected well drilling liquid reduces discharging, and produces
Raw solid phase can reach environmental protection requirement with the innoxious cured of drilling cuttings.
2nd, low solid phase sulphonated polymer mud breaks environmental-protecting performance evaluation before and after glue
With reference to People's Republic of China's Gas Industry standard, " sy/t 6787-2010 water solublity Oilfield Chemicals environment is protected
Shield technical requirements ", National Standard of the People's Republic of China's " gb31571-2015 petro chemical industry pollutant emission standard ", in
Magnificent people's republic national standard " gb 8978-1996 integrated wastewater discharge standard ", National Standard of the People's Republic of China " gb
15618-1995 standard of soil environment quality ", think poorly of solid phase sulphonated polymer mud break glue before and after chemical toxicity, biodegradation
Property, bio-toxicity, the results are shown in Table 3.Wherein employ Luminous bacteria and test bio-toxicity index ec50, ec50 numerical value >=
20000mg/l then belongs to nontoxic rank；The ratio bod5/codcr employing biochemical oxygen demand on the five with COD comments
Valency biological degradability, numerical value >=0.05 item belongs to easily biological-degradable scope.
The low solid phase sulphonated polymer mud of table 3 breaks the environmental-protecting performance parameter before and after glue
From table 2 it can be seen that this low solid phase sulphonated polymer mud break glue before and after content of beary metal, bio-toxicity, biological fall
Solution property is satisfied by country's correlation environmental protection standard requirement, all no biotoxicity, biodegradable, no chemical toxicity, and after breaking gel
Bod, cod are greatly lowered (although not up to direct emission request, not affecting the recycling of liquid phase), are more easy to biological fall
Solution, all other indexs more can reach setting requirement, more conducively environmental protection after breaking gel.
3rd, low solid phase sulphonated polymer mud breaks the reuse experimental evaluation of liquid phase after glue separates
By low solid phase sulphonated polymer mud break glue separate the liquid phase producing be used for preparing the low solid phase of a spud section respectively finely divided
Drilling fluid, Erkaijing well No-Solid Phrase Polymer drilling fluid, the performance parameter contrast with the carrying out prepared using clear water, such as table 4 He
Shown in table 5.

Embodiment 5:
This breaking glue solution described is applied to discard the broken glue of low solid phase sulphonated polymer mud.
Carry out field test popularization and application, the discarded low solid phase polysulfonate of accumulative 60 mouthfuls of wells of purified treatment in Su Lige block
Drilling fluid, about 11960 sides, respond well.Property of drilling fluid before broken glue: density 1.12-1.25g/cm3, viscosity 50-80s, dehydration
2-4ml, ph8-10, after adding the kindheartedness and righteousness breaking glue solution of embodiment 2-4, discarded low solids polymer drilling fluid breaks glue completely, Gu
Liquid is substantially layered, and solid phase is in granular form or rice-shaped, can have solid phase in conjunction with drilling team's solid controlling system (centrifuge and vibrosieve)
Effect removes, after solid-liquid separation, liquid phace property: 1.01-1.03g/cm3, viscosity 28-30s, dehydration be complete lose, ph6-7, broken glue, solid
Liquid phace property parameter after liquid separates is essentially close to clear water, and the liquid phase volume of generation is broken rejected well drilling liquid volume before glue
50-55%, volume half, the control amount realizing rejected well drilling liquid reduces discharging, and this liquid phase directly reclaims and drives a well for preparing other wells one

Water more than 5600 side, reduces drilling fluid integrated cost it is achieved that rejected well drilling liquid reaches " zero-emission " " no pollution ", solves in Soviet Union
Lattice block drilling fluid " not landing " discard, after implementing, the problem that low solid phase sulphonated polymer mud nowhere discharges, and have both met safety drilling need
Ask and be beneficial to environmental conservation, economic benefit, environmental benefit project.Also promote Su Lige drilling well cleanly production to greener simultaneously
Color more low-carbon (LC) direction is developed.
The only illustration to the present invention exemplified as above, does not constitute the restriction to protection scope of the present invention, all
It is that same or analogous design belongs within protection scope of the present invention with the present invention.
