Description
Technical field
The invention belongs to technical field of lubricant, be specifically related to a kind of drilling machinery with lubricator and preparation method thereof.
Background technology
In drilling well and well-completion practice process, between drilling tool and the borehole wall, sleeve pipe, between drilling fluid and drilling tool, the borehole wall, casing wall, all friction can be produced.In the drilling process of horizontal well, orientation well, the effect of gravity makes landwaste and drilling tool assemble to borehole wall bottom, increases the contact area of drilling tool and landwaste so further, causes moment of torsion, frictional resistance to increase, thus cause the down-hole complex accident such as bit freezing.Lubricant significantly can reduce the friction resistance of drilling fluid, and therefore, the lubricity of drilling process to lubricant of horizontal well, orientation well has higher requirement.
The Main Means of the fifties in last century domestic raising drilling fluid lubricating performance is in mud, be mixed into crude oil or oil; The sixties rise and bring into use the tensio-active agent such as span80, sulfonation Yatall MA gradually; Development since the eighties is also successfully applied to and on-the-spot has the solid lubricant such as Graphite Powder 99, glass microsphere and good dispersity, unstressed configuration, biodegradable RH Series Lubricants.
From last century the seventies, along with the development of orientation well, horizontal well technology, external lubricant for drilling fluids obtains large-scale application, wherein the lubricant for drilling fluid of the U.S. is based on aniorfic surfactant, the lubricant for drilling fluid of the Soviet Union is based on fatty acid soaps class, oxidized petrolatum, Forest Chemicals and various industrial waste, and Japan is then based on various anionic and nonionic surface active agent.Above-mentioned lubricant for drilling fluid briefly can be classified as following a few class: 1. inert solid lubricant.This series products for representative, reduces moment of torsion and frictional resistance by principle sliding friction being become rolling resistance with glass microballon and plastic pellet.The application of plastic pellet (vinylbenzene obtains through becoming pearl with the multipolymer of divinylbenzene) is in recent years comparatively extensive, can reduce the moment of torsion of about 35% and the frictional resistance of about 20% under normal circumstances.2. extreme pressure lubricant.Reduce interface frictional resistance by forming firm chemical film in metallic surface, be therefore particularly useful for horizontal well and creep into needs to low frictional resistance.The product of three kinds of U.S.'s drilling company that representative is: EP-Bitlube, EP-Mudlube and EP-Lube.3. nontoxic or Biodegradable lubricant.This series products is nontoxic, environmental protection, unstressed configuration, biodegradable.Representative commodity have: Torq-Trim, temperature resistance 250 DEG C, and anticalcium 8100g/L, does not foam, and frictional resistance reduced rate is about 24%, and moment of torsion reduced rate is about 14%; DOS-3, frictional resistance reduced rate is 20% ~ 30%, moment of torsion reduced rate 21% ~ 29%; Trade(brand)name Lubeen, organic lipid mixtures, nonflammable, easily foam, frictional resistance reduced rate is about 30%, and moment of torsion reduced rate is about 62%.
Now widely used lubricant for drilling fluids or cost is higher or contaminate environment or have fluorescence to affect geological logging, all can not meet extensive horizontal well exploratory development well to the cost of lubricant for drilling fluid and performance requriements.Therefore, research and develop that a kind of fluorescence intensity is low, cost is low, the novel emulsion lubricant of high lubricating effect, produce good promoter action by the development of oil drilling industry.
