Description
Technical field
The present invention relates to a kind of oil base drilling fluid emulsifying agent and preparation method thereof.
Background technology
Continuous reduction and exploitation difficulty with petroleum reserves, countries in the world are increased to deep formation petroleum resources one after another
The input of exploration and development, develops an urgent demand that new oil reservoir has become 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 turned into restriction oil
The key factor of gas development of resources.With the increase of depth of stratum, deep-well, ultradeep well formation temperature also can more and more higher, ground
Can the hot environment of layer maintain stable performance to bring great challenge to drilling fluid.
Drilling fluid is as the important component 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, strong retraction and high temperature, superhigh temperature stratum can be especially met, or needs 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, are by oil, water, emulsifying agent, drop
Fluid loss agents, equilibrium of activation agent, flow pattern regulator etc. are constituted.Usually used Water-In-Oil drilling fluid water content is between 5~30 %
(generally referred to as full oil base drilling fluid of the water content within 5%, not referred to as Water-In-Oil drilling fluid), but high temperature resistance up to 180 DEG C with
On Water-In-Oil drilling fluid reclaimed water content it is general in 5~10 %, rarely exceed 15%.The content increase of water, takes bits property, drop filter
The property lost and suspension, rheological characteristic all improve, but heat endurance and electrical stability are all deteriorated, and such as CN1660958 reports a kind of conjunction
Into base drilling fluid, the primary emulsion used is the mixture of AESA and NPE,
Although still having good rheological characteristic and emulsion-breaking voltage after 16 hours in 150 DEG C of agings, water content is up to 25%.Patent CN
A kind of high-temperature water-in-oil drilling fluid of 102031095 A Shen Qing Publications, although heatproof can be to 240 DEG C, but it must be by auxiliary breast
The presence of agent and calcium oxide can be only achieved application effect.Oil base drilling fluid is therefore expensive because base fluid is based on oil, into
This height, full oil base drilling fluid is even more so, as CN101215461 reports a kind of complete-oil synthetic base drilling fluid, the emulsification used
Agent is one or more mixtures in Long carbon chain fatty acid amide, Long carbon chain alkyl benzene calcium sulfonate, polyolefin carboxylic acid ester, to the greatest extent
Pipe has the advantages that low toxicity, environmental protection, small to reservoir damage, but it prepares cost height, limits it and promotes the use of.
There is provided of less types as oil base drilling fluid emulsifying agent in the market, and report the breast for intensified oil reduction
Agent kind is relatively more, and such as US4485873, US4545912, CN100531884 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.It is in terms of domestic oil base drilling fluid emulsifying agent to rely on external more
Product, and domestic supporting drilling fluid system is also less.
Oil base drilling fluid due to limited by cost, environmental requirement develop always it is relatively slow, the block of application also compared with
Few, as existing oilfield reserve increasingly declines, and the exploitation in new exploratory area can run into various bad grounds and environment, be badly in need of carrying out
Satisfaction prepares the research of stability and high efficiency oil base drilling fluid emulsifying agent, to solve oil base drilling fluid emulsifying agent less varieties, emulsibility
Can be poor, not the problem of salt tolerant, non-heatproof, the cost of reduction oil base drilling fluid is reached by improving the ratio of oil base drilling fluid reclaimed water
Problem, to provide technical support extensively using oil base drilling fluid operation.
In the case of exactly this high-moisture of the present invention, it is suitable for preparing the breast of stability and high efficiency oil base drilling fluid
Agent and preparation method thereof.
