Description
Technical field
The preparation method who the present invention relates to a kind of methyl glucoside glycoside compound and this methyl glucoside glycoside compound uses lubrication inhibitor with the drilling fluid that contains said methyl glucoside glycoside compound.
Background technology
Along with the expansion in petroleum natural gas exploration field and deeply, probing exploitation dynamics constantly increases, and the probing difficulty improves, and the drilling complexity degree is more outstanding.Special conditions wells such as deep-well, ultra deep well, orientation well, long horizontal traverse well, horizontal well, multiple wells, slim hole well are more and more, and drilling speed need increase substantially.The increase of therefore, drilling well difficulty also proposes higher requirement to lubricant for drilling fluids.
Lubricant for drilling fluids commonly used at present has mineral oils, modification plant-animal oils, surfactant-based and polyvalent alcohol and polymerization alcohols.The mineral oils lubricant is big for environment pollution, and fluorescence grade is high, and the preparation maintenance requirement is strict, thereby under the situation of environment protection increasingly stringent, has lost competitive edge gradually; Conventional polyvalent alcohol and polymeric alcohol series products effective content vary within wide limits, a little less than the inhibition, the cloud point instability, and also most of product exists in drilling fluid and increases glutinous, bubble problem, and some polymeric alcohol product can not reduce the filter loss of drilling fluid, increases filter loss on the contrary; Cost an arm and a leg though modification plant-animal oils is the polyol lubricant, its performance is good, and is nontoxic, and fluorescence grade is low, and is easy to use, thereby obtained using widely.
In the world and domestic petroleum drilling well professional range, mud shale well section hole instability is the technical barrier of puzzlement drilling technology always.Field practice shows that in numerous difficulty wells, its difficult point just is well to solve the wellbore stability problem of mud shale well section, causes problems such as down-hole accident takes place frequently, drilling cost improves, infringement hydrocarbon zone.
When boring chance water sensitivity mud shale stratum; Owing to contain the clay mineral of smectite, illite or illite/smectite mixed layer in this type stratum; Can under the drilling fluid filtrate hydration, expand, broken, physics and chemical action such as peel off, cave in, cause complexcase such as hole shrinkage, slump in; Cause bit freezing, suppress Lou accident such as stratum and take place, influenced drilling speed, damaged hydrocarbon zone.
At present; The inhibitive drilling fluid system serves as to suppress core with single inorganic salt or organic salt both at home and abroad; Use this kind drilling fluid through a large amount of rig-site utilization, showed certain inhibition ability, can solve the problem of water sensitivity mud shale well section hole instability to a certain extent.But, also exposed some problems, for example can't avoid introducing negatively charged ion or anion radical; Increase drilling fluid salinity etc.
Methylglucoside (MEG) is by a six-membered ring structure, methoxyl group (OCH3), four hydrophilic hydroxyls.Can on the borehole wall, form the such adsorption film of the similar water-in-oil mud of one deck, this film can separate water in the shale and the water in the drilling fluid.MEG is owing to contain four hydroxyls on its ring molecule on the other hand; Its water absorbability is very strong, promptly can form firm hydrogen bonded with water molecules, therefore; Filtrating in the MEG drilling fluid enters in the stratum; Its effect is different from common fresh water, and it has the effect that makes anhydrating of formation rock, thereby has good inhibition oilness.MEG is a kind of glucide, therefore can biological degradation under the enzyme effect, environment is not polluted.But a little less than finding that in field use MEG temperature resistance ability, at high temperature be prone to decompose and lose its performance.
Summary of the invention
Technical problem to be solved by this invention provides the methyl glucoside glycoside compound that a kind of drilling fluid uses and the preparation method of this methyl glucoside glycoside compound; Provide a kind of drilling fluid that contains said methyl glucoside glycoside compound to use lubrication inhibitor simultaneously, its strong inhibition capability, oilness be good, property of drilling fluid is had no side effect, other drilling operation program is not had negative impact and can use lubrication inhibitor by biodegradable drilling fluid.
