Description
Technical field
The invention belongs to cement defoaming agent field of compound material, and in particular to a kind of oil-well cement high efficiency composition defoaming agent and
Preparation method.
Background technique
During oil gas well cementing operation construction operation, due to applying a variety of additives in cement slurry, lead to process with slurry
Middle generation foam, thus reduce cement slurry density and other performance causes site operation to be difficult to monitor and to control cement slurry close
Degree and performance.
It under continuous execution conditions, such as cannot quickly defoam, it will so that cement slurry actual density is significantly less than true value, lead
Cement strength and cementing strength is caused to reduce, acoustic amplitude logging curve is higher, to influence cementing quality；Simultaneously as this mistake
False information is by Real-time Feedback to stock mixing system, it will causes oil-well cement to change with the ratio with pulp-water, while also affecting water
The effective content of various additives in mud causes the parameters such as its rheological property, fluid loss, thickening time and design to generate inclined
Difference.
In addition, the cement slurry of bubbles will change head of liquid in well, the fluid in high pressure formation will enter annular space,
Make the cementing variation between cement sheath bonding quality and cement sheath and casing and the borehole wall, or even gas (water) occur and alters, construction quality without
Method guarantees that even resulting in construction can not be normally carried out, and cementing operation failure is directly resulted in when serious.So such cement slurry is necessary
Using defoaming agent except defoaming, it can guarantee construction progress and construction quality.Therefore, a kind of defoaming agent of function admirable is being cemented the well
Occupy very important status in construction.
Currently, domestic defoaming agent kind has several hundred kinds, be used primarily in papermaking, printing and dyeing, coating, biofermentation, cleaning, at water
The industries such as reason and petrochemical industry, only on a small quantity specifically for the defoaming agent of oil-well cement slurry system.Domestic defoaming agent is various in style,
Different properties, composition are broadly divided into organic silicon type, polyether-type and non-silicon type three categories.Organic silicon defoamer has dosage
Small, the advantages that defoaming capacity is strong, volatility is low, anti-oxidant, nontoxic, tasteless, without side-effects；Polyether antifoam agent can be by adjusting oxygen
Ethylene (EO), the ratio of oxypropylene (PO) and molal weight adjust its water-soluble and oil-soluble, substantially reduce the surface of expanding foam solution
Tension has defoaming, foam inhibition ability well；Non-silicon type defoaming agent refers to be organised with fatty acid amide, phosphate, alcohol, ether etc.
A kind of defoaming agent based on object is closed, defoaming, foam inhibition ability are poor.
Because there is the features such as being vigorously stirred and shake mixed with additive, in process for preparation in well cementing mortar architecture,
Therefore, defoaming agent used is in addition to requiring higher defoaming capacity, also require to have in mortar architecture it is comparable water-soluble or
Dispersibility, be to mortar architecture it is inert, not with other additive chemically reactives, it is without side-effects to mortar architecture,
