Description
Technical field
The present invention relates to the free hydraulic control preparations of the cementing slurry in oil gas well cementing operation field to be furtherly related to one
Free hydraulic control preparation of kind cementing slurry and the preparation method and application thereof.
Background technology
In the diameter segment well cementation in oil gas well cementing operation field, in annular space concrete column, effect of the larger particle in gravity
Under can settle, may have the tendency that aggregation and bridge plug, and when free liquid in position below bridge plug is populated with just produces water
Slot or water band, when pressurization, cause Behavior of Hardened Cement Paste to rupture.In addition to this, free liquid, which is assembled, to form water pocket and also interferes cement to casing and ground
Layer it is cementing.It may also prematurely be gelled, lower static pressure is generated to stratum or not generate static pressure, and has channeling occurs.Horizontal well
In well cementation, the free liquid that horizontal segment is formed can be moved up gradually, when reaching a certain amount of, the free liquid capsule phase on annular space cement top
It is intercommunicated, free liquid bath or water band are constituted, has channeling is also easily led to, influences cementing quality.
The additive of the free liquid of control or extra material mainly have in well cementation at present：Bentonite, attapulgite, sodium metasilicate,
Diatomite, waterglass, natural volcanic ash, flyash, alum or aluminum sulfate, cellulose, aluminium chloride, superfine cement etc., but
Its function and effect has certain limitation.Such as bentonite, attapulgite, the free liquid effect unobvious of diatomite control and influence
Cement strength；Superfine cement hydration rate is too fast, and there are uncertainties；Sodium metasilicate, waterglass are used frequently as early strength agent,
The variation of its dosage can influence cement paste rheological matter, control free liquid effect unobvious；Alum or aluminum sulfate, cellulose, alkali formula
Aluminium chloride etc. easily makes cement mortar thicken.The above additive or extra material exclusive use are not fully solved in well cementation freely
The control problem of liquid does not form the free hydraulic control preparation for stablizing maturation.
Qiu it is mediate and etc. describe liquid silicon and can reduce the free liquid of cement mortar.(Qiu Xiehe, Wang Liangcai, Guo Guangping
.Microblock the evaluation of liquid silicon and application [J] Drilling and completion fluids .2010 (04) in Chinese oil field) wherein introduce
Liquid silicon is used as free hydraulic control preparation, has obvious effects on, but in the technical solution liquid silicon dosage it is larger, general addition 10% with
On.
