Abstract
The invention aims to provide a novel drilling fluid lubricant. The novel drilling fluid lubricant comprises the following components in percentage by weight: polyoxy enol ether, an emulsifier, fatty acid aluminum and residual oil according to the ratio of (5-20): (0.1-5): (1-10): (0.1-0.5). The novel drilling fluid lubricant has the beneficial effects of attractive lubricating property; by utilizing the lubricant in the field, the torque of a drill steam and the resistance of a summer drill can be reduced effectively, the accident of hamming of a drilling tool is reduced, the drilling fluid is not affected, the thickening and bubbling are avoided, the filter loss is reduced a little, and the environmental influence is small.
Description
Technical field
The present invention relates to a kind of formulating being applicable to oil field drilling fluids lubricant, belong to chemicals field.
Background of invention
Lubricant for drilling fluid is a kind of important drilling fluid chemical processing agent, improves drilling fluid lubricating, reduce the friction between the borehole wall and sleeve pipe or drilling tool during its effect, reduce drill string rotating moment of torsion and its under bore resistance, thus reduce the generation of lock of tool drilling.In recent years due to the development of drilling technique, the demand of drilling fluid sharply increases, therefore drilling fluid lubricating performance comes into one's own day by day.Presently, be the kind of lubricant or performance all has sizable distance comparatively abroad.Mainly there is following shortcoming and problem in the lubricant for drilling fluid of current onsite application: easily causes drilling fluid to bubble, easily cause drilling fluid viscosity to raise, be unfavorable for drilling fluid field maintemance; Time has been grown fermentation phenomenon; Anti-salt, anticalcium are undesirable, unstable in seawater drilling fluid; Environment is had to a series of shortcomings such as detrimentally affect.
The present invention relates to a kind of composition research of lubricant for drilling fluid.Primarily of polyoxyethylene glycol ether, anionic emulsifier, fatty acid aluminium and white oil composition, respond well.
Summary of the invention
Being of mother of the present invention provides a kind of lubricant for drilling fluid.
In order to achieve the above object, this invention takes following technical scheme:
Technical scheme of the present invention is as follows:
Relate to a preparation for lubricant for drilling fluid system, it is characterized in that: be made up of component A, anionic emulsifier B, fatty acid aluminium C and residual oil, made the corresponding lubricant for drilling fluid that can obtain the present invention relates to by the above main ingredient through specialized processes.
Wherein said component A is preferably from polyoxyethylene glycol ether, polyoxypropylene diols ether, polypropylene glycerol aether, polyoxypropylene ethylene oxide glyceryl ether.
Described anionic emulsifier B preferably from: one of Sodium dodecylbenzene sulfonate, sodium laurate, tetradecyl benzene sulfonic acid sodium salt or combination.
Described fatty acid aluminium C is preferably from the unsaturated fatty acids aluminium of: sulphur activation.
In formula, the weight ratio of each component is as follows: polyoxy enol ether: emulsifying agent: fatty acid aluminium: residual oil is (5-20): (0.1-5): (1-10): (0.1-0.5).
The invention has the advantages that lubricity is good, effectively can reduce drill string torque at the scene and play the summer and bore resistance, reduce lock of tool drilling, drilling fluid is had no adverse effects, not thickening, non-foaming, to filter loss slightly reducing effect, to features such as environmental influence are little.
Embodiment
Below in conjunction with embodiment, the present invention is described further, but is not limited only to this.
Embodiment 1:
Raw material and proportioning:
Polypropylene glycerol aether: 10 parts, sodium laurate 2.5 parts, fatty acid aluminium 8 parts, 0.3 part, residual oil.
Preparation method:
Press formula ratio respectively, once polypropylene glycerol aether, sodium laurate, fatty acid aluminium are joined in residual oil, after mix and blend 2-4h, can lubricant for drilling fluid be obtained.
Embodiment 2:
Raw material and proportioning:
Polypropylene glycerol aether: 15 parts, sodium laurate 3.0 parts, fatty acid aluminium 10 parts, 0.3 part, residual oil.
Concrete compound method is with embodiment 1.
Above-described embodiment is only and clearly the invention example is described, and the restriction not to the invention embodiment.For those of ordinary skill in the field, other multi-form change and variations can also be made on the basis of the above description.Here exhaustive without the need to also giving all embodiments.
