Description
Technical field
The invention belongs to pressure break oil recovery technique field is and in particular to one kind prepares extremely-low density fracturing propping agents using white clay
Method.
Background technology
Fracturing propping agents are to support the crack producing in Oil/gas Well hydraulic fracturing process, strengthening the water conservancy diversion energy on stratum
Power, improves oil, the yield of gas and a kind of wide variety of solid particle.Preferably proppant should have the characteristics that：(1) strong
Degree is high, will not be crushed for heavy duty service；(2) relative density is little, is easy to pump into underground；(3) chemical inertness is good, can resist ground
In layer, the erosion of water body, equally stable at high temperature；(4) sphericity is good, to keep preferable space between proppant particles.
Existing proppant is broadly divided into three types.Oil fracturing ceramsite propping agent is prepared with raw mineral materials such as bauxites
Development existing many documents and patent report.Haydite class proppant not only expensive it is often more important that due to relative density
Greatly, the viscosity requiring load fluid in construction must be very high, and this high viscosity load fluid is usually organic polymer solution (example
As：Guanidine glue), pressure break energy consumption is big, high cost and pollute environment and destroy in-place permeability.
Equations of The Second Kind proppant is mainly some natural materials such as quartz sand (US patent 5,420,174 to
Deprawshad et al；US patent 5,218,038 to Johnson et al and US patent 5,639,806
to Johnson et al:EP patent No.0542397).This kind of proppant is cheap and easily-available, and relative density is about in 2.5.
In shallow well, application quartz sand has certain success rate for proppant.But because of sand insufficient strength, (pressure when starting broken is about
For 25MPa), in the case that closure stress is higher, will crush, produce substantial amounts of fragment and fine silt.These fine silts exist
Migrate in crack and block crack, thus reducing the flow conductivity in crack.In hydraulic fracturing job, using such
Support agent also has a unsurmountable shortcoming, and that is, they all can embed stratum or occur when Oil/gas Well puts into production proppant anti-
Tell or crack emptying phenomenon.
3rd class is organic resin application type proppant.These resins mainly include epoxy resin, furan, phenolic resin or
Their mixture.The content of resin is usually to be applied the 1-8% of particle weight, and particulate matter can be sand, haydite, pulverizing
The walnut shell crossed or other particulate matters.Chinese patent 200710188410 disclose " preparation method of low-density propping agent and
Preparation technology ", Chinese patent 201010278084 discloses " a kind of fiber composite sand control material and preparation method thereof ", respectively profit
With Plant fiber or fibrous material as raw material, in organic curing non-sintered molding or incorporation fracturing fluid, play sand prevention Oil Guide
Effect, and there is relatively low density, they only need in use can as fracturing fluid with tap water or saline
To meet the requirement of pressure break oil recovery, this kind of proppant is referred to as extremely-low density fracturing propping agents.But this kind of proppant often has by force
The low defect with temperature tolerance difference and high cost of degree.
Thus, research and develop a kind of high intensity, low-density, low cost fracturing propping agents, for improve China's oil and gas production and
Grade is most important；Additionally, being applied in pressure break oil recovery technique, secondary environmental pollution will not be brought and reduce
Its cost of manufacture, will have obvious environment demonstration benefit and economic benefit, and meet China's strategy of sustainable development requirement.
Content of the invention
The present invention is intended to provide a kind of intensity is high, density is low, the preparation side of low cost, process is simple fracturing propping agents
Method.
For reaching above-mentioned purpose, as follows using technical scheme：
A kind of method preparing extremely-low density fracturing propping agents using white clay, comprises the following steps：
1) white clay, coupling agent is taken to be scattered in stirring in toluene, reaction terminates rear sucking filtration, drying, obtains modified white clay；Described white
Mud is residue of aluminum-extracted pulverized fuel ash；Coupling agent addition is the 1-5wt% of white clay；
2) with water as disperse medium, add modified white clay after adding dispersant, then Deca is dissolved with cross-linking agent and initiator
Monomer solution carry out polyreaction, filter, washing, dry and obtain extremely-low density petroleum fracturing propping agent；Wherein, polyreaction
Water in mass ratio：Dispersant：White clay：Monomer：Cross-linking agent：Initiator=140:0.4～1.2:2～6:15～30:3.0～5.0:
0.25～0.45 is carried out.
By such scheme, described coupling agent is silane coupler or aluminate coupling agent.
By such scheme, described dispersant is Mg (OH)2.
By such scheme, described cross-linking agent is divinylbenzene or cyclopentadiene.
By such scheme, described initiator is benzoyl peroxide.
By such scheme, at 60 DEG C of described polyreaction, add dispersant, monomer solution is warmed up to 75-80 DEG C after dripping
Reaction 0.5-1h, 1-2h, 90-95 DEG C of reaction 1h of 85 DEG C of reactions terminate.
White clay is a kind of thermal power plant waste coal ash residue of aluminum-extracted, and main component is Si and Al, with most of nothing
Machine mineralogical composition is close, can be used for building block, brickmaking, the low-grade concrete of system.But greatly still it is used for filling out hole, paving
Road, it is made a low multiple use, and governments at all levels all take much count of the process problem of white clay, but there is presently no more preferable Application way.
The technical scheme is that with modified white clay as inorganic additive, the method system that MMA adopts suspension polymerisation for organic monomer
Standby compound proppant.The low-density of the existing high molecular polymer of proppant being so obtained and high tenacity, and organic/inorganic substance
Intensity and temperature tolerance, and white clay and macromolecular chain PMMA interaction, the motion hindering polymer macromolecule chain is thus improve
Overall temperature tolerance and comprcssive strength.
Beneficial effects of the present invention：
By add in high molecular polymer building-up process a certain amount of modification white clay can reach raising polymer strong
Degree and durothermic purpose, thus in being applied to, deep well fracturing uses, and is the product that Petroleum Industry creates more high-quality.
The proppant density prepared is 1.08～1.25g/cm3, density, close to water, can use salt in use
Water serves as load fluid, such that it is able to pressing crack construction cost is greatly reduced, and reduce avoid using the pluronic polymers such as guanidine glue drop
The low pollution to environment.
Both increased utilization rate and the added value of white clay, reduce the preparation cost of extremely-low density fracturing propping agents.And make
Standby process is simple is suitable to industrialized production.
