Description
Technical field
The invention belongs to pressure break oil recovery technique field, be specifically related to a kind of method of utilizing white clay to prepare extremely-low density fracturing propping agents.
Background technology
Fracturing propping agents are the cracks that produce in supporting oil gas well waterfrac treatment process, strengthen the flow conductivity on stratum, improve the output of oil, gas and a kind of solid particulate of widespread use.Desirable propping agent should have following characteristics: (1) intensity is high, can be not crushed for heavy duty service; (2) relative density is little, is convenient to pump into underground; (3) unreactiveness is good, can resist the erosion of water body in stratum, at high temperature stable equally; (4) degree of sphericity is good, to keep good space between proppant particles.
Existing propping agent is mainly divided into three types.The existing many documents of development and the patent report of with raw mineral materialss such as bauxitic clays, preparing oil fracturing ceramsite propping agent.Haydite class propping agent is not only expensive, the more important thing is because relative density is large, in construction, require the viscosity of sand-carrying agent must be very high, for example, and this high viscosity sand-carrying agent (: guanidine glue), pressure break energy consumption is large, cost is high and contaminate environment and destruction zone permeability is generally organic polymer solution.
Equations of The Second Kind propping agent is mainly that some crude substance are 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 class propping agent is cheaply easy to get, and relative density is about that in 2.5., to apply quartz sand in shallow well be that propping agent has certain success ratio.But because of sand insufficient strength (pressure while starting fragmentation is about 25MPa), in the situation that closure stress is higher, will be broken, produce a large amount of fragments and fine silt.These fine silts move and stop up crack in crack, thereby reduce the flow conductivity in crack.In waterfrac treatment operation, use such propping agent to also have a unsurmountable shortcoming, they all can embed stratum or when Oil/gas Well puts into production, occur that propping agent is counter to be told or the emptying phenomenon in crack.
The 3rd class is organic resin application type propping agent.These resins mainly comprise epoxy resin, furans, resol or their mixture.The content of resin is generally the 1-8% of coated particle weight, and particulate matter can be nut-shell or other particulate matter of sand, haydite, pulverizing.Chinese patent 200710188410 discloses " 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 ", utilize respectively vegetable fibre or filamentary material as raw material, organicly solidify non-sintered moulding or mix the effect of playing sand prevention Oil Guide in fracturing liquid, and there is lower density, they in use only need to just can meet as fracturing liquid the requirement that pressure break is recovered the oil with tap water or salt solution, and this class propping agent is called extremely-low density fracturing propping agents.But this class propping agent often has the defect that intensity is low He temperature tolerance is poor and cost is high.
Thus, research and develop a kind of high strength, low density, fracturing propping agents cheaply, for improving, China's oil and gas production and grade are most important; In addition, be applied in pressure break oil recovery technique, can not bring secondary environmental pollution and reduce its cost of manufacture, will there is obvious environment demonstration benefit and economic benefit, and meet China's strategy of sustainable development requirement.
Summary of the invention
The present invention aims to provide that a kind of intensity is high, density is low, cost is low, the preparation method of the simple fracturing propping agents of technique.
For achieving the above object, adopt technical scheme as follows:
Utilize white clay to prepare a method for extremely-low density fracturing propping agents, comprise the following steps:
1) get white clay, coupling agent is scattered in toluene and stirs, reaction finish rear suction filtration, oven dry, obtain modified white clay; Described white clay is residue of aluminum-extracted pulverized fuel ash; Coupling agent add-on is the 1-5wt% of white clay;
2) take water as dispersion medium, add modified white clay after adding dispersion agent, then drip the monomer solution that is dissolved with linking agent and initiator and carry out polyreaction, filter, washing, dry and obtain extremely-low density petroleum fracturing propping agent; Wherein, polyreaction water in mass ratio: dispersion agent: white clay: monomer: linking agent: carry out initiator=140:0.4～1.2:2～6:15～30:3.0～5.0:0.25～0.45.

White clay is a kind of fuel-burning power plant waste residue of aluminum-extracted pulverized fuel ash, and main component is Si and Al, close with most of inorganic mineral composition, can be used for building block, and brickmaking, makes low-grade concrete.But greatly still for filling out hole, paving the way, it is made a low multiple use, and governments at all levels all take much count of the processing problem of white clay, but also there is no at present better utilised method.Technical scheme of the present invention is that to take the white clay of modification be inorganic additives, and MMA is that organic monomer adopts the method for suspension polymerization to prepare compound propping agent.Low density and the high tenacity of the existing high molecular polymer of propping agent making like this, the intensity of organic/inorganic substance and temperature tolerance again, and white clay and macromolecular chain PMMA interact, thereby the motion of obstruction polymer macromolecule chain improves whole temperature tolerance and ultimate compression strength.
Beneficial effect of the present invention:
By add the white clay of a certain amount of modification in high molecular polymer building-up process, can reach and improve polymer strength and durothermic object, thereby in being applicable to, deep well fracturing uses, for Petroleum Industry has been created the more product of high-quality.
The propping agent density of preparing is 1.08～1.25g/cm
3, density, close to water, in use can be served as sand-carrying agent with salt solution, thereby can significantly reduce pressing crack construction cost, and reduces and avoid using the pluronic polymers such as guanidine glue to reduce the pollution to environment.
Both increase utilization ratio and the added value of white clay, reduced the preparation cost of extremely-low density fracturing propping agents.And preparation technology is simply suitable for suitability for industrialized production.
