Abstract
The invention relates to a preparation method of coupling phenolic resin used for a drilling fluid, and the method comprises the following steps: successively adding 100 parts of phenol and 60 parts to 200 parts of formaldehyde according to mass ratio into a reaction vessel with a backflow cooler of a mixer, heating to 80 - 100 DEG C, stirring and reacting for 30 - 50 minutes under the effect of 1 - 3 parts of A type catalyst, then adding 10 parts - 20 parts of B type catalyst and 150 parts - 200 parts of sulfonate to heat at the temperature range of 90 DEG C - 105 DEG C to react for 1 - 2 hours, then adding 50 - 100 parts of aminosilane coupling type high-molecular polymer, and reheating to the temperature range of 90 DEG C - 105 DEG C for continuing the reaction for 2 - 4 hours, and then discharging the material to obtain coupling phenolic resin. According to the invention, when coupling phenolic resin is taken as a fluid loss agent with heat and salinity tolerance used for the drilling fluid, the high-temperature high-pressure filtration loss is reduced by 8 - 15%, the cloud point salinity is raised by 10 - 20% than that of common sulfonation phenolic resin on the key index tests, and the quality of the filter cake is raised so that the filter cake is thin and dense.
Description
Technical field
The present invention relates to polymeric material field, be specifically related to the preparation method of a kind of petroleum drilling industry drilling fluid with anti-salt temperature resistance fluid loss agent, promptly drilling fluid is with the preparation method of coupling resol.
Background technology
Borehole well instability is to influence the principal element that drilling well is carried out smoothly always in the drilling process, and on-the-spot the employing usually to adding fluid loss agent in the drilling fluid addresses this problem.Yet the temperature resistance ability of existing fluid loss agent is generally not high; Generally be no more than 160 ℃; Prior art mainly adopts sulfonated phenol formaldehyde resin as fluid loss agent, and high temperature resistance highly compressed filter loss is unstable, and anti-salt is lower; Especially under the situation that geologic framework differs greatly, just need the littler and higher fluid loss agent of salt resistance of filter loss.
Summary of the invention
The objective of the invention is to overcome the deficiency of existing petroleum drilling industry drilling fluid with anti-salt temperature resistance fluid loss agent, provide a kind of anti-salt, temperature resistance and adsorptivity performance all greatly the enhanced drilling fluid with the preparation method of coupling resol.
In order to achieve the above object; The present invention has adopted following technical scheme: a kind of drilling fluid is with the preparation method of coupling resol; This preparation method is: by the quality proportioning 100 parts phenol, the formaldehyde of 60-200 part are added in the reaction kettle of the reflux cooler that has stirrer successively; Under the effect of 1-3 part category-A catalyzer, heated 80-100 ℃ of stirring reaction 30-50 minute, add then 10-20 part category-B catalyzer and 150-200 part sulphonate heat 90-105 ℃ the reaction 1-2 hour; The aminosilane coupling family macromolecule polymkeric substance that adds 50-100 part is again heated 90-105 ℃ again and is continued reaction discharging after 2-4 hour, get final product coupling resol.The present invention can further process coupling resol aqua and pulvis is packed sale.
Above-mentioned category-A catalyzer (acid catalyst) is selected from a kind of in hydrochloric acid, tosic acid or the oxalic acid.
Above-mentioned category-B catalyzer (alkali catalyst) is selected from sodium hydroxid, a kind of in Marinco H or the Pottasium Hydroxide.
Above-mentioned aminosilane coupling family macromolecule polymkeric substance is selected from N-2-(aminoethyl)-3-aminopropyl trimethoxysilane, N-(β aminoethyl)-γ-aminopropyl methyl-dimethoxy silane or 3-aminopropyl triethoxysilane.
Above-mentioned sulphonate is selected from Sodium Pyrosulfite or vitriolate of tartar.
The present invention also comprises and utilizes the prepared drilling fluid of aforementioned preparation method to use coupling resol.
Principle of the present invention is: phenol, formaldehyde, sulphonate are reacted the preliminary resol of formation under the effect of catalyzer; Adding aminosilane coupling family macromolecule polymkeric substance again reacts again; Obtain coupling resol; Mainly show as and add after aminosilane coupling family macromolecule polymkeric substance reacts again, the resin that obtains uses key property to strengthen to some extent.After being mainly reflected in adding coupling high molecular polymer in the practical application, inorganic components in the base slurry and organic composition have improved cohesive action and have fallen the filter effect through coupled action.
Beneficial effect of the present invention is: among the present invention; Select different aminosilane coupling family macromolecule polymkeric substance, be added in the late phase reaction of resol, through the effect of functional group; Molecule is coupled together or inlays additionally each other, play the effect of strengthening the property.Use the coupling resol that this technical recipe produces can be as drilling fluid during with anti-salt temperature resistance fluid loss agent; Improve a lot than common sulfonated phenol formaldehyde resin (SMP-II type) in the test of key index, specific as follows: as under 180 ℃ temperature, to test: 1, high temperature and high pre ssure filtration reduces 8-15%; 2, the cloud point salinity improves 10-20%; 3, the quality that has improved filter cake makes filter cake thin and fine and close (after adding the coupling high molecular polymer, the inorganic components in the base slurry and organic composition be through coupled action, improved cohesive action and fall and filter effect).
Measure according to standard method, the coupling resol of preparation technology's preparation of the present invention is processed corresponding aqua and pulvis carries out index determining respectively, testing index is seen table 1:
The coupling resol of table 1 preparation technology's preparation of the present invention is processed corresponding aqua and pulvis index.
Above-mentioned coupling resol aqua and pulvis all adopt the sulfonated phenol formaldehyde resin aqua commonly used at present and the preparation method of pulvis to make.
