Description
Technical field
The present invention relates to a kind of amphoteric ion type lubricant, the invention further relates to a kind of containing amphoteric ion type lubricant
Water-base drilling fluid, belong to petroleum drilling technology field.
Background technology
The lubricant of traditional water base drilling fluid system is based on the mineral oil such as crude oil, diesel oil, machine oil.Wherein, crude oil is in height
Stable oil film can be formed under the maximum conditions such as warm high pressure in the stress surface of drilling tool and palisades.Due to substantial amounts of high viscous in crude oil
Spend colloid to exist, oil film still is able to keep greasy property under the severe rugged environment of high temperature extreme pressure, turns into drillng operation in face of high-leveled and difficult
The down hole problem of well is spent, improves the maximally efficient selection of lubricant effect.
And increasingly strict environmental requirement is faced, increasingly stricter limitation has been subjected to using crude oil lubrication technology.For
Preserve the ecological environment, meet the requirement of environmental regulation, always search for substituting the environment protective lubricant of crude oil both at home and abroad.
United States Patent (USP) US4181617 just developed water-base drilling fluid lubrication oily based on rapeseed oil early in 1980
Agent.So far most of oilfield services enterprise uses the type product still in the better simply well of some structures.Due to the plant used
Thing oil belongs to edible oil and fat, and the problem of there is food is striven with the people, while cost is higher.
Publication No. CN103045183A Chinese invention patent discloses a kind of trench oil lubricant, use gutter oil for
Lubricant is made in base oil, and the lubricant, which can effectively solve the problem that, drops moment of torsion and frictional resistance problem in drilling process.But trench oil component
It is more complicated, not only contain the impurity such as vegetable oil, the also higher animal fat of degree of saturation, free fatty, lecithin into
Point.Due to the presence of these components so that easily become morally degenerate when temperature is higher by the lubricating oil of main component of gutter oil,
Effect declines；Easily solidification is lumpd again when temperature is relatively low, influences to disperse in drilling fluid, it is unnecessary to cause to construction operation
Trouble.
Publication No. CN 102851004B Chinese invention patent discloses a kind of drilling fluid biodegradable lubricants,
Grease is reacted by the higher biological ester of generation stability using ester exchange reaction, it is relatively low to largely solve winter temperature
When lubricant solidification agglomeration problems.In addition, Synthin with certain viscosity temperature characteristic also with good lubricity and
Environmental-protecting performance.The lubricant belongs to emulsion droplet type lubricant, and test indoors has good lubricant effect, but in Holes of Complicated Wells,
Especially horizontal well sidetracking when, lubricating ability deficiency.
In order to improve grease scattering problem, Publication No. CN102952528A Chinese invention patent applications, one kind is disclosed
Degradable lubricant for drilling fluid, the emulsifying agent and a certain amount of water that 5 ~ 10% are added in 80 ~ 90% biodiesel carry out breast
Change, grease is dispersed in drilling fluid by surfactant, most domestic oily lubricant belongs to this type at present.
Publication No. CN103756651A Chinese invention patent application, oil phase, the table are disperseed using extraordinary nonionic surfactant
Oil phase can be separated into the emulsion droplet of nano-scale by face activating agent, improve the storage problem of the type lubricant.Publication No.
CN103756651A Chinese invention patent application, the higher paraffin of the coefficient of viscosity is separated into a nanometer emulsion droplet, improves oiliness
Scattering problem of the material in drilling fluid, surface of drill stem and the borehole wall.Because oily material is dispersed into nano particle, thus in drilling tool
Scattered evenly with borehole wall surface, lubricity is significantly improved compared with the large scale oiliness emulsion droplet of coarse dispersion.But moisten
The emulsion droplet that lubrication prescription oil phase is formed, equivalent to flexible particle, can cause bad in drilling process to the rheological characteristic of drilling fluid
Influence, while had a great influence in the distribution of friction aspect by emulsion droplet degree of scatter, it is not easy to formed uniformly in stress surface
Lubricating layer, so as to cause its using effect unobvious in the complex structural wells such as high angle hole, ultradeep well.
Above-mentioned environment protective lubricant effectively can not still solve or drop when in face of complex structural wells such as horizontal well, extended reach wells
Low down hole problem.Have environmental protection concurrently, integrate lubrication, suppression, compatibility etc. it is multi-functional lubricant exploitation it is less, especially
There can be the lubricant of crucial greasy property under highly difficult complex working condition still in space state.
