Description
Technical field
The invention discloses a kind of drilling fluid tackifier, belong to technical field of petroleum extraction.
Background technology
Drilling fluid, is the various circulation of fluid general names for meeting drilling well need of work in drilling process with its multiple functions.Ground
The harsh environment of lower drillng operation promotes the research and development to drilling fluid, it is desirable to can be completed in drilling process following more
Item key task：Suspension, pressure control, rock stratum stability, buoyancy, lubrication and cooling.
Drilling fluid is different from the physicochemical property of cement mortar, in well cementation due to annular space stream etc. reason can cause both blend and
Contact stain is produced, slurry section fluid mobility occurs because chemistry is incompatible and deteriorates suddenly.The harm of contact stain is：Slurry
Section flow resistance increase influences replacement efficiency, and Lou weak floor may be pressed and cause cementing " low to return " and " leakage by being pumped quick rise
Envelope "；Slurry high thixotropic may cause " plant flag bar " accident etc..The technical measures for solving contact stain at present have：1. carry out well
Lower different fluid compatibility test, adjusts Working solution prescription repeatedly, to improve slurry mobility；2. adjustment property of drilling fluid simultaneously makes
Use insulating liquid.But deep well cementing practice have shown that, slurry is difficult to avoid that, and some additive for drilling fluid when mixing proportion is minimum still
It is one of insoluble basic reason of contact stain to cause slurry mobility to deteriorate.In terms of contact stain research, Ma Yong etc.
Drilling fluid and the incompatible reason of cement mortar chemistry are analyzed；Yang Xiangyan proposes " two slurries " and interferes model；Liu's generation
Refined grade has carried out the anti-pollution experiment of cementing slurry and has screened the additive for drilling fluid for having blood coagulation enhancing effect to cement mortar；Joel etc.
The property of drilling fluid after by cement contaminants is studied with Fakhreldin etc.；But the studies above does not verify contact stain also
Mechanism.It is maximum that Cementing Practices find that the additive for drilling fluid such as biological tackifier, KPAM, JD-6 influences cement mortar mobility.But
Be used the drilling fluids of tackifier also there are tackifier Efficient Adhesive Promotion it is bad the problem of, therefore also need to study it.
The content of the invention
The present invention solves the technical problem of：It is bad for traditional drilling fluid tackifier Efficient Adhesive Promotion, there is provided one
Kind drilling fluid tackifier.
In order to solve the above-mentioned technical problem, the technical solution adopted in the present invention is：
A kind of drilling fluid tackifier, is made of the raw material of following parts by weight：

4~8 parts of emulsifying agent
35~45 parts of water
6~10 parts of polyacrylamide
3~5 parts of dispersant
The preparation method of the coal oil mixture is：
By medium temperature coal tar and high temperature coal-tar in mass ratio 2：1~3：1 mixing, and add medium temperature coal tar quality 0.1~0.2
Modified cellulose again, is stirred, obtains coal oil mixture；
The preparation method of No. 1 additive is：
By Petropols and terpene resin in mass ratio 2：1~4：1 mixing, and add the knot of 0.4~0.6 times of Petropols quality
Cold glue, is stirred, and obtains No. 1 additive；
The preparation method of No. 2 additives is：
By organic siliconresin and paraffin in mass ratio 1：2~1：3 mixing, and add the catalysis of 0.06~0.07 times of organosilicon quality
Agent, is stirred, Freezing smashing, and sieving, obtains No. 2 additives；
The preparation method of the drilling fluid tackifier is：
（1）Formed by raw material and weigh each component；
（2）Base oil, coal oil mixture, No. 1 additive and No. 2 additives are stirred, oil phase blank is obtained, will emulsify
Agent, water, polyacrylamide and dispersant are stirred, and obtain water phase blank, water phase blank and oil phase blank are stirred, must bore
Well liquid tackifier.
The base oil is white oil, any one in dimethicone or soybean oil.
The emulsifying agent is sorbester p17, sorbester p18, any one or the combination of several of them in polysorbas20 and polysorbate60.
The dispersant is dispersant NNO, any one in Dispersant MF or dispersant 5040.
The modified cellulose is any one in hydroxymethyl cellulose or hydroxypropyl cellulose.
The Petropols are any one in C5 Petropols or C9 Petropols.
The catalyst is diethylenetriamine, any one in triethylene tetramine or ethylenediamine.
The beneficial effects of the invention are as follows：
（1）The present invention adds coal oil mixture when preparing drilling fluid tackifier, on the one hand, the medium temperature in coal oil mixture
Coal tar component can make the high temperature coal-tar component of coal oil mixture dispersed after adding in drilling fluid tackifier system
In drilling fluid tackifier system, also, medium temperature coal tar has certain suction-operated, so that thickening of the product to drilling fluid
Effect improves, and on the other hand, the high temperature coal-tar component in coal oil mixture has preferable adsorption capacity, is adding drilling well
After in liquid tackifier system, the Efficient Adhesive Promotion of drilling fluid tackifier can be effectively improved in use, therefore increase in drilling fluid
Coal oil mixture is added in stick can effectively improve the Efficient Adhesive Promotion and lubricity of drilling fluid tackifier；
（2）The present invention adds No. 1 additive and No. 2 additives when preparing drilling fluid tackifier, first, in No. 1 additive
Petropols can improve the greasy property of drilling fluid in use, and Petropols can coordinate terpene resin and tie cold
Glue, further improves the viscosity of drilling fluid, therefore adding No. 1 additive in drilling fluid tackifier can imitate the thickening of product
Fruit and greasy property further improve, and secondly, paraffin and organic siliconresin are contained in No. 2 additives, are adding drilling fluid thickening
After in agent system, after use, when drilling fluid temperature raises, No. 2 additives is paraffin melting in drilling fluid tackifier, promotes
The greasy property of product improves, and paraffin melting rear organic siliconresin appears, under the action of high temperature and curing agent, organosilicon
Resin can be partially cured, and cured resin can coat the impurity in system, while also the crack of the borehole wall can be filled out
Fill, and uncured resin can further improve the viscosity of drilling fluid due to higher crosslinking degree, therefore No. 2 additives
Addition can further improve the Efficient Adhesive Promotion of product and lubricity.
