Abstract
The invention provides one kind using plugging agent and preparation method thereof made of the dregs of fat or oily sludge, by weight percentage, preparing the raw material of the plugging agent includes following components：The water of the dregs of fat or oily sludge 30% 60%, the methyl propane sulfonic acid of 2 acrylamido 2 5% 15%, N, N methylene-bisacrylamides 5% 10%, initiator 0.5% 5%, organic retarder 0.05% 0.5%, stabilizer 0.02% 0.1%, solid phase particles 0.5% 5% and surplus.Provided by the invention have that preparation technology is simple, raw material sources are wide, cheap, environmentally friendly close friend using plugging agent made of the dregs of fat or oily sludge, plugging agent is good with stratum compatibility, it is not likely to produce flocculation, plugging strength is big, the characteristics of heat-resistant salt-resistant performance is good, and there is certain selective water plugging function, deep water plugging and profile controlling can be realized, stratum is not polluted, it is wide to adapt to Oil Reservoir Types.
Description
Technical field
The invention belongs to oil-water well profile control and water plugging field, and in particular to one kind is stifled using being adjusted made of the dregs of fat or oily sludge
Agent and preparation method thereof.
Background technology
The dregs of fat are product of the oily sludge after advanced treating, and oily sludge refers to the oil tank of oil recovery factory's multi-purpose station, sedimentation
The oil that tank, Water Tank, oil interceptor bed mud, refinery's oil-containing water processing establishment, lighter hydrocarbons processing factory, purifying device for natural gas clear out
Husky, greasy filth, drilling well, operation, conduit wiring piercing and caused ground crude oil and oily sludge.Oil product storage tank is when storing oil product, oil
The weight oily components such as a small amount of mechanical admixture, the grains of sand, soil, heavy metal salt and paraffin and asphalitine in product are deposited on oil tank
Bottom, form tank bottom oil sludge.
CN1480627A discloses one kind and emulsifying agent and dispersant is added into oily sludge, adds composite anion tree
Fat, add polyacrylamide and burnt oily sludge is made.But because manufactured plugging agent contains crude oil and water, it is unfavorable for
Transport and storage, and gelling strength is weaker, it is inadaptable to contain hypertonic passage and large fracture reservoir profile.
CN1278547A discloses a kind of multi-functional plugging agent, and the plugging agent is by Sludge in Oilfields, waste mud, swelling
Soil, calcium oxide, cement, polymer, lignin and amphimicrobe are that raw material is formed in different ratio apolegamys, polymer
Including polyacrylamide, Xanthan gun and pre-crosslinked gel particle, the plugging agent using inorganic cement, bentonite with organic due to being gathered
The compoundings such as compound, lignin form, and are influenceed by compatibility difference during field application, easy delaminating deposition, block profile control pump and well is low, lead
Frequently inspection pump is caused, influences connectivity of constructing, it is dangerous that operation occurs.It is stifled that CN1429692A discloses a kind of composite solid particle tune
Agent, the plugging agent is made up of the mixing of bentonite, acrylamide, ammonium salt initiator and water, but bentonite is easily sent out with acrylamide
Raw flocculation reaction, precipitation, while heat-resistant salt-resistant poor performance are produced, causes plugging effect undesirable.
Because natural subsidence easily occurs in Agitation Tank, profile control pump or pit shaft for existing oily sludge, and frequently examine
Pump has certain operation dangerous, construction success rate is influenceed, in addition, flocculation phenomenon of the solid phase particles such as native powder easily with polymer.
For this reason, it may be necessary to which developing one kind has good heat-resistant salt-resistant performance, and the plugging agent of above mentioned problem can be improved.
The content of the invention
To overcome above mentioned problem, it is an object of the invention to provide one kind to utilize plugging agent made of the dregs of fat or oily sludge,
The plugging agent has the characteristics that big plugging strength, heat-resistant salt-resistant, does not pollute stratum.
It is a further object of the present invention to provide a kind of preparation method of above-mentioned plugging agent.
It is yet another object of the invention to provide application of the above-mentioned plugging agent in oil-water well profile control and water plugging.
To reach above-mentioned purpose, the invention provides one kind using plugging agent made of the dregs of fat or oily sludge, with weight
Percentages, preparing the raw material of the plugging agent includes following components：
The dregs of fat or oily sludge 30%-60%, 2- acrylamide-2-methylpro panesulfonic acid 5%-15%, N, N- methylene
Bisacrylamide 5%-10%, initiator 0.5%-5%, organic retarder 0.05%-0.5%, stabilizer 0.02%-0.1%,
Solid phase particles 0.5%-5% and surplus water.
It is provided by the invention to utilize plugging agent made of the dregs of fat or oily sludge, due to the dregs of fat or oily sludge and stratum water
With good compatibility, shale adsorption gel therein and wax can be adsorbed on formation rock, and assemble shape by viscous connection
Into " crumb structure " of greater particle size；And solid phase particles can be deposited in macropore, macropore latus rectum is diminished, block Thief zone
Layer band, increases filtrational resistance, forces seepage flow to turn to, and expands and injects water swept volume, blocks water breakthrough passage, further improves to adjust and blocks up
(deposition is mainly shown as two kinds, Yi Zhongshi for agent intensity and plugging effect：Behind fluid loss to stratum, solid phase particles settle,
Natural subsidence blocks stratum to the solid phase particles that another kind is suspended in liquid under gravity)；And the dregs of fat after emulsifying
Or oily sludge forms the higher thick gel blocking layer of intensity, and weak hydrophily is shown, so as to realize that selective shut-off goes out
The purpose of water layer position.Moreover, plugging agent provided by the invention has the characteristics of big plugging strength, heatproof salt, and with selection
The function of property water blockoff.
In above-mentioned plugging agent, it is preferable that the initiator is redox type initiators；It is it is further preferred that described
Redox type initiators include water miscible redox type initiators and/or oil-soluble redox type initiators, institute
Stating water miscible redox type initiators includes hydrogen peroxide-ferrous salt, persulfate-ferrous salt or hydrogen peroxide isopropyl
Benzene-ferrous salt, the oil-soluble redox type initiators include dialkyl-DMA or peroxidating
Diacyl-N, accelerine.
In above-mentioned plugging agent, it is preferable that the water miscible redox type initiators are sodium formaldehyde sulfoxylate-mistake
Ammonium sulfate, the mass ratio of the two are preferably 3:1.
In above-mentioned plugging agent, it is preferable that organic retarder be sodium gluconate and sodium tartrate in one kind or
Two kinds of combination.It is preferred that both be because：The organic retarder of sodium tartrate category high temperature, 150-200 DEG C of well temperature is generally used for, is had
Strong retardation capability, and can improve cement mortar mobile performance；Sodium gluconate has due to there is multiple hydroxyl reactive groups
There is an extremely strong strong deferred action, still can be used during 200 DEG C of well temperature, and dosage is few, and oily sludge is suspended and had no side effect, this is
Because the presence of hydroxy-acid group adds it to Ca2+Complexing.
In above-mentioned plugging agent, it is preferable that the stabilizer includes thiocarbamide, oxalic acid, tertiary amine, naphthenate, mercaptan and had
One or more of combinations in machine metallic compound；It is further preferred that the organo-metallic compound includes Al (C2H5)3。
