Abstract
The invention relates to a preparation method of a filtration control lubricant used by a high-temperature horizontal well and directional well. In a reaction container, a glycan drilling fluid treatment agent is mixed with water, and then sodium benzoate and hexamethylenetetramine or paraformaldehyde are added; then a plant polyphenol material and lignosulfonate are added into a mixture in the reaction container; finally, a mixture in the reaction container is subjected to vacuum drying and grinding to obtain the filtration control lubricant used by the high-temperature horizontal well and directional well. Vegetable gum adopted in the preparation method is heteropolysaccharide and has a branch structure, so that the filtration control lubricant has a good lubricating effect, and a coefficient of friction resistance of a mud cake is obviously reduced; in addition, the plant polyphenol material is used as an additive of the glycan drilling fluid treatment agent, so that the structure of glycan can be stabilized by intermolecular forces of a hydrogen bond and the like, the glycan drilling fluid treatment agent is difficult to degrade and decompose when the filtration control lubricant is used at a high temperature, and temperature resistance can be improved to 150 DEG C or more.
Description
Technical field
The present invention relates to environment-friendly type Drilling Fluids for Horizontal Wells preparation and application technical field is and in particular to a kind of high-temperature water horizontal well
The preparation method of the filtrate reducing lubricant that directional well uses.
Background technology
Drilling fluid is the general name of the various circulation of fluids meeting drilling well need of work in drilling process with its several functions, quilt
It is described as " blood " of drilling engineering.Additive for drilling fluid is the core of drilling fluid, and it plays very to adjusting drilling fluid rheology
Important effect.With petroleum exploration and development to ocean and deep formation development, drilling strata condition is increasingly complicated, horizontal well and
Directional well gets more and more, this requirement more and more higher to additive for drilling fluid, by health-safety-environmental protection standard and development trend,
Develop free from environmental pollution, do not damage health, meet complex structural well and deep-well, the novel non-toxic of ultra-deep well drilling job requirements,
Free of contamination green, high-quality, efficient, inexpensive additive for drilling fluid become the direction of people's effort.
At present, on the one hand, poly- saccharide material, as modified starch, modified cellulose etc., be often used as environment-friendly type water horizontal well and
Directional well drilling liquid inorganic agent, has degradable, avirulent feature, but it is poor to there is also temperature resistance, applies in general to be less than
120 DEG C of environment.But, going deep into oil field development, well depth is increasing, and also with regard to more and more higher, this allows for its temperature
These Environment-protecting Drilling Fluids materials can not use, and is also forced to then the polymer drilling fluid material using some non-environmental protections.
On the other hand, these conventional chitosan material lubricities are limited, and the mud cake frictional resistance of formation is larger, are unfavorable in the orientation boring High angle
Use when well and horizontal well, generally needed to be added substantial amounts of lubricant agent special, reduce frictional resistance it is ensured that drilling safety, this is just significantly
Improve the complexity that the cost of drilling well and drilling fluid are prepared.
