Description
Technical field
The invention belongs to petroleum works field, in particular it relates to which a kind of be used for calcium and magnesium sediment flocculation in the water of alkali drive stratum
The device of separation, using low concentration flocculant in helical hose device mixed base and stratum water so that calcium and magnesium sediment wad a quilt with cotton
Solidifying separation.
Background technology
Viscosity of thickened oil is high, be difficult flowing, generally reduces the viscous of viscous crude by heating using the method for steam thermal recovery at present
Degree, so that viscous crude is easy to flow and be plucked out of.But if core intersection is thin or oil reservoir is especially deep, carried out using steam injection
Exploitation will result in serious thermal loss, and exploitation effect is also poor.For such viscous crude, chemical flooding particularly alkali drive is
Than better suited method.The recovery ratio why alkali drive can improve viscous crude is because anti-containing natural organic acid and alkali in crude oil
Material of the Ying Houhui generations with surface-active, so as to form W/O (Water-In-Oil) or O/W (oil-in-water) emulsion.It is newborn when forming W/O
During liquid, because W/O emulsions have very high viscosity, Thief zone region can be blocked, makes the increase of aqueous phase pressure, is adopted so as to improve crude oil
Yield；When forming O/W emulsions, the viscosity of viscous crude can be substantially reduced, so as to be displaced with aqueous phase.
Although alkali drive has extraordinary driving effect to viscous crude, be due to alkali use can cause the corrosion of equipment with
Fouling etc. endangers, and limits application of the alkali drive in thickened oil recovery.Oil exploitation water filling is typically used in stratum water, water containing big
The salt ion of amount, such as Ca2+、Mg2+Deng after being mixed with NaOH, it may occur that following reaction：
OH-+HCO3 -→CO3 2-+H2O
Ca2++CO3 2-→CaCO3↓
Mg2++2OH-→Mg(OH)2↓
The CaCO of generation3With Mg (OH)2Fouling will be gradually deposited in pipeline or stratum, for actual production extremely
It is unfavorable.Therefore, the removal of calcium ions and magnesium ions is the important prerequisite of application of the alkali drive in thickened oil recovery in the water of stratum.
At present, following several processing modes are mainly taken this in the production of oil field：
(1), by chemical precipitation method or ion-exchange-resin process etc. in advance by the Ca in the water of stratum2+And Mg2+Deng removing；
