Abstract
The present invention relates to a water soluble well drilling fluid lubricant for oil well drilling engineering and its preparation method. Said invented drilling fluid lubricant is made up by adopting light lube oil and white oil or diesel oil No.o as raw material, and adding dispersant, penetrant, emulsifier and defoaming agent in a certain proportion, heating, stirring and adding water, and making them undergo the compounding process so as to obtain the invented product. Said invented product possesses good water solubility, strong stability and less dose, and can meet the requirements for drilling fluid property in the oil well drilling engineering construction, and can greatly reduce frictional resistance coefficient of mud care, and its raw material cost is lower and its preparation method is simple, so that it can greatly reduce production cost.
Description
The present invention relates to a kind of drilling fluid that is used for petroleum drilling engineering and add treatment agent and preparation method thereof.
In Process of Oil Well Drilling, need in drilling fluid, add the multiple treatment agent that comprises lubricant.At present, on-the-spot commonly used lubricant for drilling fluid adopts diesel oil, crude oil or white oil to add tensio-active agent and the milk sap that forms mostly, its production cost higher (generally more than 5000 yuan/ton), and existing lubricant properties does not reach engine request under complex well conditions, the lubricant poor stability that has, demixing phenomenon often occurs, even cause that complexcase take place in the down-hole, influence normally carrying out of drilling engineering.
The object of the present invention is to provide a kind of both can having reached in the petroleum drilling engineering construction, can reduce water soluble drilliong lubricant of treatment agent preparation cost and preparation method thereof significantly again the lubricant for drilling fluid performance requriements.
The present invention realizes like this.This kind lubricant for drilling fluid is to adopt light lubricating oil, white oil or 0# diesel oil as raw material, add a certain proportion of dispersion agent (as tetramethylsilane, alcohol ether C8), permeate agent (OT), emulsifying agent (Tween, NP--10, OP-10) and defoamer (aluminum stearate, glycerin polyether, organosilicon) and under suitable temp, stir, add that water is composite to form.Its component (promptly use former, material and proportioning as follows:
Component (promptly using starting material) proportioning weight (%)
Lubricant: light lubricating oil, white oil 3-15
, 0# diesel oil
Dispersion agent: tetramethylsilane, alcohol ether C8 2-5
Permeate agent: OT 1-5
Emulsifying agent: Tween, NP-10, OP-10 0.1 0.5
Defoamer: aluminum stearate, glycerin polyether, organosilicon 0.1-0.5
All the other are water.
Preparation method's implementation step of this kind lubricant is as follows:
Above-mentioned former, material is added respectively in the closed reactor according to above order, proportioning, be heated to 50--60 ℃, stirred at a slow speed 1 hour; Then, pour in the uncovered stirring tank of normal temperature, restir is 1 hour behind the adding clear water, can barrelling put or transport to on-the-spot the use in storage.
Water soluble drilliong lubricant good water solubility provided by the present invention, stability is strong, consumption is few, can satisfy the performance requriements of petroleum drilling engineering construction process to drilling fluid, can reduce the coefficient of friction resistance of mud cake significantly, the material cost that is adopted is lower, preparation method and required equipment condition are simple, easy to implement, adopt product provided by the invention and preparation method, not only can reach the wellbore construction requirement, and can reduce production costs greatly, obtain good economic benefit, be suitable for and apply.
Embodiment 1: in closed reactor, add in order light lubricating oil 50kg, dispersion agent tetramethylsilane 30kg,, permeate agent OT10kg, emulsifier op-10 5kg, defoamer organosilicon 2kg, be heated to 55 ℃, stirred at a slow speed 1 hour; Miscellany is poured in the uncovered stirring tank of normal temperature, adds clear water 903kg, and restir 1 hour can be prepared into 1 ton of required lubricant for drilling fluid product.
Embodiment 2: prepare lubricant for drilling fluid according to method, the step identical with embodiment 1, the starting material and the consumption thereof that are adopted are as follows: white oil 60kg; Dispersion agent: tetramethylsilane 20kg; Permeate agent OT50kg; Emulsifying agent: NP-104kg; Defoamer: glycerin polyether 3kg; Add water 863kg.Make 1 ton of lubricant product.
Embodiment 3: prepare 1 ton of lubricant for drilling fluid according to the method described above, used former, material usage is as follows: 0# diesel oil 150kg; Dispersion agent: alcohol ether C820kg; Permeate agent: OT20kg; Emulsifying agent: Tween3kg; Defoamer: aluminum stearate 3kg; Clear water 804kg.
Claims (2)
1, a kind of water soluble drilliong lubricant, it is characterized in that this kind lubricant for drilling fluid adopts light lubricating oil, white oil or 0# diesel oil as raw material, adds a certain proportion of dispersion agent, permeate agent, emulsifying agent, defoamer, add that water is composite to form, its component and proportioning are as follows:
Component proportioning (weight %) lubricant: light lubricating oil, white oil
0# diesel oil 3-15 dispersion agent: tetramethylsilane, alcohol ether C8 2-5 permeate agent: OT 1-5 emulsifying agent: Tween, NP-10, OP-10 0.1-0.5 defoamer: aluminum stearate glycerin polyether 0.1-0.5
Organosilicon
All the other are water.
2, a kind of preparation method of water soluble drilliong lubricant, it is characterized in that, the implementation step of this method is as follows: starting material as claimed in claim 1 are added respectively in the closed reactor according to said sequence, proportioning, be heated to 50-60 ℃, stirred at a slow speed 1 hour; Then, mixture is poured in the uncovered reactor of normal temperature, restir got final product in 1 hour behind the adding clear water.
