Description
Technical field
The present invention relates to the composition and method of making the same that a kind of displacement of reservoir oil is used.
Background technology
Along with socioeconomic development, people are to the continuous increase of petroleum demand amount and the minimizing of prospective oil, and oil is just becoming more and more valuable as non-renewable resource.The problem that faces has one, and imbalance between supply and demand is outstanding, and the petroleum demand amount is more large, and find is fewer and feweri; Two, also left in exhausted oil reservoir have a substantial oil.Primary oil recovery (POR) but the underground crude oil of extraction 10～25%, secondary oil recovery (SOR) but the underground crude oil of extraction 15～25%, i.e. a primary oil recovery and secondary oil recovery extraction 25～50% underground crude oil.In order to guarantee oil supply steady in a long-term, to satisfy human wants, must research and development improve petroleum recovery technology, tertiary oil recovery (EOR) can make oil recovery factor improve 6～20% by the intensified oil reduction measure again, and is even more.
Chemical flooding is an important method that improves recovery ratio.Surfactant flooding is considered to improve by a relatively large margin a kind of chemical agent of recovery ratio, applied widely, tool development prospect.No matter tensio-active agent is as host or as the auxiliary agent displacement of reservoir oil, all plays immeasurable effect to increasing substantially recovery ratio.Polymer displacement of reservoir oil tech is a kind of method of important raising oil recovery, compares with general water drive, and polymer flooding can accelerate oil recovery process, improves economic benefit, and Processes and apparatus is simple, cost is lower.As an important technology in chemical flooding, the ASP Oil-Displacing Technology that polymkeric substance, tensio-active agent and alkali form has carried out some field tests in China and foreign countries, has obtained good oil displacement efficiency.But the adding of alkali cause occurring in field test the problems such as the fouling of producing well pit shaft is serious, Produced Liquid difficult treatment, make the application prospect of ASP Oil-Displacing Technology allow of no optimist.By contrast, do not use alkali in the binary combination flooding formula that polymkeric substance and tensio-active agent form, the mining site operability is stronger, thereby is subject to the approval in oil field.But due to need not any alkali, crude oil PetroChina Company Limited. acids active substance can not be fully used, so that research and development have novel surfactant and an alkali-free binary combination flooding formula of high surface more is imperative.
The Surfactant Industry product of external used for tertiary oil recovery mainly contains two large classes: the one, and sulfonated petro-leum is main tensio-active agent, the 2nd, alkylbenzene sulfonate is main tensio-active agent, this two classes tensio-active agent raw material is all taken from crude oil, raw material sources are wide, quantity is large, thereby are also the tensio-active agents of external tertiary oil recovery consumption maximum.Because sulfonate surfactant is anionic, it and the divalent cation (Ca in local water
2+, Mg
2+Deng) can precipitate, work as Ca
2+, Mg
2+Just lose oil displacement efficiency when surpassing 300 μ g/g.For this reason, also be fit to high saliferous, high Ca in continual exploitation research abroad
2+, Mg
2+The tensio-active agent that the ion stratum is used comprises the research of multi-functional tensio-active agent, Gemini surface active agent and sacrifice agent, and pays attention to the composition research of various tensio-active agents.
the anion-nonionic amphoterics is one of focus of tertiary oil recovery (EOR) area research in recent years always, owing in its molecular structure, two kinds of non-ionic groups of different nature and anionic group being designed in same surfactant molecule, make it have the advantage of negatively charged ion and nonionogenic tenside concurrently, have complementary advantages, excellent property, therefore shown good application prospect, especially the binary combination flooding system that exists for alkali-free, due to the obstruction of not only having avoided oil reservoir that there is no alkali, the problem such as fouling and corrosion, and can form ultra low interfacial tension with crude oil.In recent years, because Shuangzi (Gemini) tensio-active agent is by two hydrophilic radicals, two hydrophobic groupings and is connected and connects a base key and close the special construction compound that forms, has more good performance than conventional surfactant, make it have ultra low interfacial tension, low micelle-forming concentration, low Kraff point, good lime soap dispersing power, good a series of peculiar properties such as wettability, thereby cause great concern.Gemini tensio-active agent with interface performance and rheological is expected to replace the alkali in the ternary composite driving formula, under rational formula system, finally realizes binary displacement system, for the chemical flooding in oil field is opened up new approach.
In the patent application at beginning of the thirties late 1920s, Degroot (De Groot) just once proposed the recovery ratio that the water soluble surfactant active helps to improve oil.
At present, the main Gemini surface active agent of domestic research and development is mainly the positively charged ion double quaternary ammonium salt type, as Chinese patent CN 1528853, CN 1817431, CN 1066137 etc. reported in succession that the bisamide type is cationic, fluorine-containing cationic type and contain the pyridyl cation Gemini surfactant.The absorption loss is large, the high in cost of production shortcoming because positively charged ion has, the research and development of anionic and non-ionic type Gemini surface active agent have in recent years also obtained increasing attention, have reported the synthetic of the asymmetric Shuangzi of a kind of negatively charged ion as Chinese patent CN 101073757.And to have salt tolerance poor due to aniorfic surfactant, and non-ionic type has the poor shortcoming of temperature tolerance, makes these products can't being applied at high temperature and high salt oil deposit.
In addition, in existing ternary composite oil-displacing system, the alkali that contains high density, as sodium hydroxide, sodium carbonate etc., in use, to bringing huge injury in stratum and oil well etc., the tensio-active agent that uses is difficult for being biodegradable, and human body also there is certain hazardness, as: 1991, Zhao Guoxi was at " tensio-active agent physical chemistry " P495; 1994, disclosed content in Liu Chengzai " tensio-active agent is complete works of " P35.So for those harsh oil reservoirs, we ought to seek a kind of under alkali-free, high temperature (formation temperature is greater than 85 ℃), high salt (more than salinity 40000mg/L) condition Stability Analysis of Structures, and can form 10 with crude oil
-3～10
-4The mN/m ultra low interfacial tension effectively improves the displacing surfactant system of oil recovery factor.Of the present invention this in the alkali-free situation just, be suitable for the moon of high temperature and high salt oil deposit-non-Gemini surface active agent, its preparation method, binary is compound and the application in tertiary oil recovery.
Summary of the invention
