Abstract
An aqueous slurry composition for use in industries such as the petroleum and pipeline industries includes a particulate, an aqueous liquid and a chemical compound that renders the particulate surface extremely hydrophobic. The slurry is produced by rendering the surface of the particulate extremely hydrophobic during or before making the slurry.
Description
Background of invention
Invention field
The method that the present invention relates to water-soluble serous composition and prepare such composition.
the discussion of prior art
Generally use in the multiple industry that comprises oil, pipeline, building and cleaned industry etc. or run into the water-based particulate slurry.Slurries are usually comprise the mixture of particle and aqueous medium and play an important role in multiple industrial operation.For example, slurries are for being delivered to particle the another location at different distance place by a position, and this conveying can be on the ground, or by earth's surface to stratum or by stratum to earth's surface.The most frequently used particle comprises sand, ceramic particle, carbonate particle, glass sphere, bauxite (aluminum oxide) particle, coated particle and the coal particle of resin.Granular size is generally approximately 10 U.S. sieves to about 100 U.S. sieves, and pellet density is significantly higher than the density of water.For example, the density of sand is about 2.6g/cm
3, and the density of water is 1g/cm
3.Sand is the most frequently used so far particle.
In order to prepare metastable slurries, must be in static state or/and under dynamic condition, particle be suspended the long period in liquid medium.General knowledge is told us, and the viscosity of liquid medium or visco-elasticity is high ability suspended particle enough.The viscosity or the viscoelastic most popular method that increase liquid medium are by liquid medium, adding tackifier, for example natural or synthetic polymer or viscoelastic surfactant.Usually common polymkeric substance and the whipping agent of using is to utilize visco-elasticity and foam properties.Yet, in slurries, use polymkeric substance to increase cost and caused operational difficulty.In concrete application, for example, in the waterfrac treatment on stratum, because a large amount of resistatess is stayed in stratum, the use of polymkeric substance in slurries hinders the gentle production of oil.For viscoelastic surfactant, although they are more less than resistates with common polymer phase, its cost is usually higher.In many other application, as gravpack, completion with carries sand by pipeline, very expectation prepares stable particulate slurry and does not use tackifier.
The waterfrac treatment operation is widely used in the production of petroleum industry to promote that oil is gentle.In waterfrac treatment, fracturing liquid is injected into to stratum by pit shaft being enough to cause under the pressure of pressure break, this can increase the gentle production of oil.The particle suspension that often will be called propping agent is delivered to breaking part in fracturing liquid and as slurries.Propping agent comprises known particle in sand that sand, ceramic particle, bauxite ore particles, resin are coated and other industry.Wherein, sand is the most frequently used so far propping agent.
Normally used fracturing liquid comprises water base and hydrocarbon-based fluids.In aqueous fracturing fluid, usually use polymkeric substance or viscoelastic surfactant to increase the visco-elasticity of fluid.In most of the cases, the visco-elasticity of fluid is essential for carrying propping agent to go deep into stratum.In the final stage of fracture treatment, fracturing liquid is back to earth's surface and propping agent is stayed to breaking part, forms proppant pack to prevent breaking part closure after pressure release.The breaking part of proppant pack provides highly conductive passage, and it allows oil and/or gas more effectively to infiltrate pit shaft.The conductivity of proppant pack plays an important role in volume increase.The known conductivity that can greatly reduce proppant pack from of the fracturing fluid polymer residues.
With polymeric viscosifiers, compare, the infringement that viscoelastic surfactant causes stratum and proppant pack is less.Yet they will hold high more expensive.
Therefore, need for effectively carry propping agent deeply to stratum with low cost, stratum and proppant pack are caused the composition of very microlesion simultaneously.The particle diameter of propping agent, concentration, shape and filling model are also to determine conductive important factor.Although conduct extensive research in recent years, the progress obtained aspect the conductivity maximization of proppant pack in making tomography is limited.Therefore, need to be for the preparation of the composition of the conductive propping agent with improvement.
Proppant backflow after fracture treatment is perplexing petroleum industry for a long time.Backflow has reduced the amount of propping agent in the breaking part, causes the tomography conductivity to reduce.For example, at United States Patent (USP) the 6th, disclosed in 047, No. 772, attempted several different methods to solve reflux problem.In a method, use resin to be coated with propping agent and to make it very toughness.Like this, proppant particles tends to be bonded together, and reduces and refluxes.The method is not only expensive, and the tackifying resin of introducing proppant pack tends to reduce its conductivity.Therefore, need to be for the preparation of composition and the method for slurries, described slurries can form the stable proppant pack of anti-proppant backflow, have highly conc simultaneously.
When oily when gentle to find at strata drilling, usually use water-base drilling fluid.Produce a large amount of particles in drilling process, be called drilling cuttings.Drilling cuttings has the different size from the fine powder to the cobble.Drilling fluid circulates with on the spot with the drilling cuttings prepared slarry and it is transferred out to pit shaft by pit shaft.In most of the cases, in order effectively to carry drilling cuttings, in drilling fluid, add polymkeric substance and clay to increase its viscosity/visco-elasticity.Yet polymkeric substance and well as clay fines can be easy to infiltrate the hole on stratum or thin breaking part near the remarkable especially perviousness of pit shaft of stratum that reduces.The formation permeability impedes oil reduced and/or the production of gas.Therefore, very expectation provides and can enough drilling cuttings prepares on the spot stable slurry and it is transferred out to pit shaft and stratum caused to the drilling fluid of minor harm.
The oil price and the alarming oil consumption speed that progressively rise have impelled people to consider to use coal as oily substitute.Several factors have slowed down coal substituting oil.A factor is to be difficult to by pipeline, coal to be grown to distance with low cost carry.Therefore, high expectations is provided for preparing the composition of the coal slurry that also can carry with low cost stable, high flow.
In the oil-sand operation, oil is being stayed from the sand sur-face peeling to a large amount of sand.Found the more economical pipeline that passes through since industry is medium-term and long-term always sand is being grown to the method that distance is effectively carried.Therefore, for composition and the method for preparing stable and particle loaded fluid high flow with low cost, can be very useful.

The detailed description of invention
The present invention's discovery, when particle surface of the present invention becomes extremely hydrophobic, the slurries that prepare with such particle have several novel character.For example, it is mobile that particle tends to adhesion ground, rather than move with the individual particles form; The cumulative volume of sedimented particle tends to substantially exceed the cumulative volume of sedimented particle in the slurries that form by ordinary method under identical condition; The grain packing formed is tended to have highly conc and can be easy to dehydration, and described slurries are that flow and stable while tending to not use tackifier under static state or dynamic condition.Grain packing than long-pending larger porousness and the consequent larger conductivity of showing of large population.This is especially useful for improving fracture treatment, and this is because as mentioned above, the conductivity of proppant pack is the main character that affects fracture treatment.Once the extremely hydrophobic surface of particle has further reduced towing force and the complete sedimentation of particle that fluid applies, makes propping agent more difficult by fluid removal.This is especially favourable for proppant backflow after fracture treatment is minimized, and this causes the conductivity of propping agent to increase.In conventional slurries, viscosity and the visco-elasticity of liquid play a major role, and the interfacial interaction role between particle surface and liquid can be ignored.Yet, the present invention's discovery, when particle surface becomes extremely hydrophobic, the importance of the interfacial interaction between surface and liquid increases.
Usually, the interfacial interaction between solid substrate and liquid depends primarily on the surface properties of solid and the surface tension of liquid.Usually can characterize the macroscopic property of solid surface by the shape of observing drop on solid substrate, the shape of described liquid is the result of the free energy of surface free energy and liquid.When the incomplete wetted surface of liquid, its formation is called as the angle θ of contact angle.Contact angle is the angle formed between the tangent line at the point of contact place between drop and solid substrate and solid substrate.Can on the solid substrate on macroscopic view, level and smooth, atresia, plane, directly measure contact angle, this is by only a drop of liquid or solution being placed on solid substrate and measuring contact angle by any of multiple technologies.The value of the contact angle between many kinds of solids and waterborne liquid is provided in various books well known by persons skilled in the art and scientific publications.Known most of natural mineral is hydrophilic.Known some hydrocarbon compound also, for example some traditional quaternary surfactant, amine tensio-active agent and cationic polyacrylamide can be used in the surface that reduces some particle and can and make the particle surface wetting ability descend or hydrophobicity increases.Yet " hydrophobicity " that such compound is given is not high enough, can not be included in term of the present invention " extremely hydrophobic ".In the present invention, " extremely hydrophobic " refers to that the contact angle of water on solid substrate surpasses approximately 90 °.Under large like this contact angle, the nonwetting solid surface of water, but shrink on solid surface and form the globule.For the sake of simplicity, can make the extremely hydrophobic compound of particle surface be called " giving extremely hydrophobic compound " (EHRC).EHRC is those compounds that contain organosilane or organic siloxane group normally.Due to such group, EHRC can give the hydrophobicity of solid surface to traditional hydrocarbon-surfactant or inaccessiable level of polymkeric substance.Known these compounds can make multiple inorganic solid surfaces extremely hydrophobic.
Can prepare on the ground or preparation on the spot in stratum by slurries of the present invention.Such slurries serve many purposes in multiple industry, comprise for (a) the particle transport different distance, perhaps on earth's surface, perhaps from earth's surface to stratum, perhaps from stratum to earth's surface, and (b) well services operation, comprise that stimulation, drilling well, completion, gravpack, control sand produce etc.
In addition, gas can be mixed into to slurries of the present invention.The suitable gas can be used in slurries comprises air, carbonic acid gas, nitrogen, methane and composition thereof.In can in the slurries preparation process, gas being introduced to slurries.For example, when by the pipeline pumped slurry, the gas such as nitrogen can be introduced to slurries, or will simply be mixed into slurries such as the gas of air by enough stir speed (S.S.)s.
In the present invention, the water that " waterborne liquid " refers to water, salts solution, contains alcohol or other organic solvent.The usage quantity or the use-pattern that should be appreciated that in waterborne liquid the additive that is different from water do not have a negative impact to the present invention.Can in waterborne liquid, add polymkeric substance.For example, in so-called riverfrac treatment operation, usually in waterborne liquid, add a small amount of polymkeric substance to reduce the friction pressure in pumping procedure.
In composition of the present invention, particle is of a size of approximately 10 U.S. sieve to 100 U.S. sieves, i.e. about 150 μ m to 1400 μ m.Should be appreciated that the distribution of sizes of particle can be narrow can be wide.Suitable particle comprises sand, ceramic particle, granulated glass sphere, bauxite ore particles, coated sand, carbonate and the coal particle of resin.
