Abstract

The invention discloses a lubricating agent for a drilling fluid and a preparation method thereof. The invention aims to design a lubricating agent for a drilling fluid which is low in cost and does not pollute the environment. According to the technical scheme, the lubricating agent for a drilling fluid comprises vegetable oil and methanol, wherein the vegetable oil accounts for 70-90 percent of the weight of the components, and the methanol accounts for 10-30 percent of the weight of the components. The method for preparing the lubricating agent for a drilling fluid comprises the following steps: heating the selected vegetable oil to 100-110 DEG C, slowly adding the selected methanol, uniformly stirring, continuously heating for 3-4 hours, stopping heating, naturally cooling the mixed liquid to be 30 DEG C or below, and finishing the preparation. The lubricating agent for a drilling fluid has the advantages of stable performance, no toxicity, easy biodegradation and slight environmental pollution, the friction between the wall of a well and a drilling tool can be effectively reduced, the drilling production cost is reduced, and the drilling production efficiency is improved.

Description

A kind of lubricant for drilling fluids and preparation method thereof
Technical field
The present invention relates to petroleum drilling fluid field, particularly a kind of lubricant for drilling fluids and preparation method thereof.
Background technology
Drilling fluid is a kind of working fluid that can carry the multiple effects such as drilling cuttings, cooling and lubricating drill bit, equilibrium strata pressure, protection wellbore stability and protection oil reservoir preserve from drilling process; its performance directly has influence on drilling efficiency, downhole safety and cost control, is the important component part of drilling engineering technology.And lubricant for drilling fluid is a kind of important drilling fluid chemical processing agent, its effect is to improve drilling fluid lubricating, reduces the friction between the borehole wall and drilling tool, reduces drill string rotating moment of torsion and the resistance that makes a trip, thereby reduces the generation of lock of tool drilling.
In recent years, due to the development of drilling technique, drilling fluid lubricating performance is had higher requirement.Now with lubricator many employing mineral oil allotment forms, because the biological degradability of mineral generation is poor, environmental pollution is serious, along with the continuous enhancing of mankind's environmental consciousness, environmental requirement to lubricant is also more and more higher, in the urgent need to developing environment amenable lubricant.
Summary of the invention
The object of the invention is to design a kind of cost lubricant for drilling fluids lower, free from environmental pollution.
Technical scheme of the present invention is that a kind of lubricant for drilling fluids, is characterized in that: lubricant for drilling fluids comprises vegetables oil and methyl alcohol, and the composition by weight of described vegetables oil is 70-90%, and the composition by weight of methyl alcohol is 10-30%.Described vegetables oil is: soybean oil, peanut oil, rapeseed oil or sewer oil.
A preparation method for lubricant for drilling fluids, is characterized in that: the vegetables oil of choosing is heated to 100-110 ℃, more slowly add the methyl alcohol of choosing, after uniform stirring, continuous heating 3-4 hour, stops after heating, liquid after to be mixed naturally cools to below 30 ℃, completes preparation.
The present invention has advantages of that stable performance, nontoxic, readily biodegradable and environmental pollution are little, can effectively reduce the friction between the borehole wall and drilling tool, has reduced drilling well production cost, has improved the production efficiency of drilling well.
