Description
Technical field
The present invention relates to a kind of drilling fluid both sexes heat and salinity tolerance fluid loss additive and preparation method, belong to oilfield chemistry drilling well
Liquid inorganic agent field.
Background technology
It will be percolated when drilling fluid flows through permeable formation under stress in drilling process, cause the filtrate of drilling fluid to be invaded
Enter stratum, this process is commonly referred to as " dehydration ".If not controlling dehydration, the reduction of liquid phase volume will increase cement slurry density,
Thickening time, the former design requirement of rheology sexual deviation, substantial amounts of liquid, which flows into stratum, makes cement mortar become to be difficult to pump, and to stratum
Different degrees of injury is caused, filtrate invaded formation can not only cause shale hydration to expand, hole instability is caused when serious
With various down hole problems.Fluid loss additive is generally added in drilling fluid, the rheological characteristic of drilling fluid can be improved, by well
Low-permeability, flexible, thin and compact filter cake are formed on wall, the filter loss of drilling fluid is reduced as far as possible.
As oil-gas exploration and development develops to deep formation, bore the stratum met and become increasingly complex, property of drilling fluid is wanted
Ask harsher, the control of rheological characteristic and filter loss has turned into restriction drilling liquid technology particularly under high density drilling fluid hot conditions
The principal element of development.Under the high temperature conditions, the effect partial of existing additive for drilling fluid or completely lose, if in saliferous
Under the conditions of, such case can be more serious.Therefore, the need for the ultra-deep well drilling, domestic and international expert and scientific research personnel are in anti-height
Carry out a series of research work in terms of warm additive for drilling fluid, but these researchs focus primarily upon the polymerization object space of vinyl monomer
Face, and due to the limitation of group on the molecular structure and molecule of such polymer, in control drilling fluid high-temperature high pressure filter loss
Aspect goes back Shortcomings.
For this it is contemplated that a kind of new fluid loss additive of exploitation solves asking for high temperature and high pre ssure filtration in the prior art
Topic.
