Description
Technical field
The present invention relates to a kind of oil base drilling fluid and preparation method thereof.
Background technology
Along with constantly reducing and exploitation difficulty of petroleum reserves, countries in the world increase one after another to deep formation petroleum resources
The input of exploration and development, develops new oil reservoir and has become as an urgent demand of current each major oil companies development.China waits to verify
Petroleum resources be mainly distributed on Tarim Basin, Zhunger Basin, Qaidam, tell the basins such as Kazakhstan, Sichuan, the 73% of its stock number is imbedded in
Deep layer, and underground condition complex, therefore deep-well and ultradeep well oil gas drilling and supporting development technique have become restriction oil
The key factor of gas development of resources.Along with the increase of depth of stratum, deep-well, ultradeep well formation temperature also can be more and more higher, ground
Can the hot environment of layer maintain stable performance to bring challenge greatly to drilling fluid.
Drilling fluid is as the important component part of drilling engineering, and its performance is directly connected to the drilling well matter of deep-well, ultradeep well
Amount, drilling cost and drilling period.Relative to water-base drilling fluid, oil base drilling fluid has stronger anti-collapse inhibition, lubricity
With good reservoir protection performance, especially can meet strong retraction and high temperature, superhigh temperature stratum, or need to bore big displacement exceptional well
And seaborne horizontal well etc. is special turns drilling well needs.Oil base drilling fluid, also known as Water-In-Oil drilling fluid, is by oil, water, emulsifying agent, fall
Fluid loss agents, equilibrium of activation agent, flow pattern regulator etc. form.Normally used Water-In-Oil drilling fluid water content is between 5～30%
(water content generally referred to as full oil base drilling fluid, the most referred to as Water-In-Oil drilling fluid within 5%), but high temperature resistance reaches more than 180 DEG C
Water-In-Oil drilling fluid in the content of water typically 5～10%, rarely exceed 15%.The content of water increases, and takes bits property, filtration reduction
All improve with suspension, rheological characteristic, but heat stability and electrical stability are all deteriorated, as CN1660958 reports a kind of synthesis base
Drilling fluid, the primary emulsion of use is the mixture of AESA and NPE, although
Still having good rheological characteristic and emulsion-breaking voltage at 150 DEG C after aging 16 hours, water content is up to 25%, but higher temperature and water
Performance under content has no report.Oil base drilling fluid is owing to base fluid is based on oil, the most expensive, and cost is high, and full oil base bores
Well liquid is all the more so, and as CN101215461 reports a kind of complete-oil synthetic base drilling fluid, the emulsifying agent of use is Long carbon chain fat
The mixture of one or more in acid amide, Long carbon chain alkyl benzene calcium sulfonate, polyolefin carboxylic acid ester, although having low toxicity, ring
Protect, to advantages such as reservoir damage are little, but its preparation cost is high, limits it and promotes the use of.
There is provided in the market and be used as the of less types of oil base drilling fluid emulsifying agent, and report the breast for intensified oil reduction
Agent kind is the most, as US4485873, US4545912, CN100531884 etc. report polyoxyethylated alkyl phenol second
Hydrochlorate, double tail chain polyoxyethylene sulfonic acid salt, alkyl-fragrant benzyl-polyethenoxy ether anion surfactant answering in terms of intensified oil reduction
With, but it is not directed to its purposes in terms of well-drilling liquid emulgent.
Oil base drilling fluid is developed relatively slower owing to limiting by cost, environmental requirement always, and the block of application is the most relatively
Few, along with existing oilfield reserve declines day by day, and the exploitation in new exploratory area can run into various bad ground and environment, is badly in need of performance
Excellent oil base drilling fluid, to solve existing oil base drilling fluid emulsion-stabilizing performance problem poor, not salt tolerant, non-heatproof.Pass through
Improve the ratio of water in oil base drilling fluid and reduce the cost of oil base drilling fluid, provide for extensively application oil base drilling fluid operation
Technical guarantee.In the case of the most this high-moisture described in invention, it is suitable for Fatty alcohol polyoxyethylene polyoxypropylene ether carboxylic
Hydrochlorate is oil base drilling fluid of emulsifying agent and preparation method thereof.
Summary of the invention
One of the technical problem to be solved is that in prior art, oil base drilling fluid emulsion-stabilizing performance is poor, is weak to
