Technical field
The present invention relates to oilfield oil well yield-increasing technology field, in particular to a kind of fracturing liquid.
Background technology
Waterfrac treatment is the major measure of low permeability oil and gas field effective exploitation, desirable fracturing liquid should be have certain viscosity in construction, the requirement made seam and take sand can be met, and can thoroughly break rapidly glue after construction terminates, to ensure the of the fracturing fluid row of returning fast, thus reduce the injury of reservoir and supporting crack. For many years; guanidine gum fracturing fluid good takes sand, heatproof resistant to shearing, broken glue performance with it; and relatively low cost; occupy the leading position in domestic and international fracturing liquid market; since the end of the year 2011; affecting by multiple factors such as country of origin climatic anomaly, the protection of local employer's organization, international demand are vigorous, guanidine film price skyrockets several times, defines huge cost pressure to domestic Low permeable oil and gas reservoirs fracturing reform.
Summary of the invention
It is an object of the invention to provide a kind of fracturing liquid, the sandfrac for Low permeable oil and gas reservoirs is transformed.
Fracturing liquid of the present invention is made up of base liquid A and base liquid B, and during construction, 100% proportioning is as follows by weight for base liquid A and base liquid B:

100% proportioning is as follows by weight for base liquid A:
100% proportioning is as follows by weight for base liquid B:
Wherein:
Thickening material in base liquid A is xanthan gum, produces by Shandong Fufeng Fermentation Co., Ltd. Can being wound around mutually with low-molecular weight polymer, collaborative increasing is glued.
The molten thickening material that helps in base liquid A is methyl alcohol, ethanol, propylene glycol or glycerol, xanthan gum can be disperseed well, suppress " flake " to generate, pass through hydrogen bond action simultaneously, make the winding of low-molecular weight polymer and xanthan gum tightr, it is to increase system takes sand performance.
Low-molecular weight polymer code name FS944 in base liquid B, is produced by Beijing Xi Tao technological development company limited, is system synergistic thickening agent, in 40min can complete swelling, resistance to flow is low, and degraded is easily.
Other additives are the conventional product in oil field, wherein:
Gel breaker is ammonium persulphate, Potassium Persulphate, clorox or hydrogen peroxide. According to the selected kind of reservoir temperature and execution conditions and the amount of adding.
Clay stabilizer is Repone K, dimethyl diallyl ammonium chloride or epoxypropyl trimethylammonium chloride ammonium. According to the selected kind of reservoir clay type and content and the amount of adding.
Cleanup additive is non-ion fluorin carbon surface active agent and low-carbon alcohol (��C6) compound product, non-ion fluorin carbon surface active agent weight ratio is 1% ~ 3%, low-carbon alcohol (��C6) weight ratio is 5% ~ 20%, surplus is deionized water. According to the selected kind of reservoir situation and the amount of adding.
Sterilant is dodecyl dimethyl ammonium chloride, hexadecyldimethyl benzyl ammonium ammonium chloride, octadecyldimethyl ammonium chloride, Surchlor GR 60, sodium trichloro-isocyanurate, isothiazolinone or BIT. According to the selected kind of region water quality and bacteria types and the amount of adding.
Emulsion splitter is polyethylene oxide-polypropylene oxide, polyoxyethylene polyoxypropylene propylene glycol or polyoxyethylene polyoxypropylene quadrol. According to the selected kind of properties of fluid in bearing stratum and the amount of adding.
Low-temp activation agent is trolamine or diethanolamine. According to the selected kind of reservoir temperature and the amount of adding.
Base liquid A process for preparation:
First sucking sterilant and help molten thickening material with jetting stream vacuum, circulate 10 minutes, then slowly suck thickening material, it is desired to prevent formation " flake ", then suck clay stabilizer, cleanup additive, emulsion splitter and low-temp activation agent, fed in raw material Posterior circle 20 minutes. Require swelling more than 4 hours of base liquid, and circulate 15 minutes before construction.
Base liquid B process for preparation:
First slowly sucking low-molecular weight polymer with jetting stream vacuum, it is desired to prevent from forming " flake ", then suck sterilant, clay stabilizer, cleanup additive, emulsion splitter and low-temp activation agent, fed in raw material Posterior circle 20 minutes. Require swelling more than 1 hour of base liquid, and circulate 15 minutes before construction.
Form of construction work:
Novel fracturing liquid injects well head by base liquid A and base liquid B by after different ratios field mix, two kinds of base liquid have certain viscosity, according to construction total flow rate and both ratios, realize by following two kinds of modes: 1. a kind of base liquid discharge capacity is less, adds pump pump by liquid and enters mulling pond or manifold; 2. discharge capacity is relatively big, by two truck-mounted blenders mulling feed flow respectively.
The useful effect of the present invention:
Novel fracturing liquid of the present invention, has and good takes sand, heatproof resistant to shearing and broken glue performance, it is possible to the sandfrac requirement on stratum within meeting 60 DEG C.
