Definitions
- the invention relates to the technical field of viscosity-reducing recovery of heavy oil, in particular to a catalyst composition and its preparation method and application.
- heavy oil recovery technology mainly includes cold recovery technology, thermal recovery technology and composite recovery technology combining cold recovery and thermal recovery.
- thermal recovery technology mainly includes cold recovery technology, thermal recovery technology and composite recovery technology combining cold recovery and thermal recovery.
- steam injection-based thermal recovery technology is the most widely used.
- the research group of Southwest Petroleum University proposed the low-temperature catalytic oxidation oil recovery technology of air injection in heavy oil reservoirs in 2002.
- This technology is to inject gas under reservoir conditions.
- inject a suitable catalyst to increase the low-temperature oxidation rate of crude oil, increase oxygen consumption and release heat, and at the same time form flue gas or nitrogen to assist external injection of high-dryness steam to improve heavy oil recovery and effectively increase formation energy , Environmental friendliness, low cost and high heat utilization rate.
- the safety of air injection low-temperature catalytic oxidation technology for heavy oil has always been the focus of academic attention, especially for the safety of production wells.
- the commonly used low-temperature catalytic oxidation catalysts for heavy oil injection into air such as oil-soluble metal salts, nano-metal catalysts, and dual-function catalysts, all have problems such as low catalytic effect, easy agglomeration, and high preparation costs to varying degrees.
- the key to solving this technical problem lies in Obtain a suitable low temperature oxidation viscosity reducer.
- the purpose of the present invention is to overcome the above-mentioned technical deficiencies, provide a catalyst composition and its preparation method and application, and solve the technical problem of high catalyst cost and poor viscosity-reducing effect in the prior art.
- the technical solution of the present invention provides a catalyst composition and its preparation method and application.
- the present invention proposes a catalyst composition, calculated according to mass percentage, comprising: free azacarbene 1-4wt%, azacarbene iron 1-2wt%, phase transfer catalyst 15-30wt%, hydrogen donor 1-5wt%, Phosphoric acid 5-10wt%, emulsifier 0.5-1wt%, and the rest are solvents, 100% in total.
- styrene tar is also included.
- the hydrogen donor is methanol.
- the solvent is benzene.
- the emulsifier is Span 80.
- phase transfer catalyst is a quaternary ammonium salt.
- the quaternary ammonium salt includes one or both of benzyltriethylammonium chloride and ammonium bromide.
- the present invention also proposes a method for preparing the catalyst composition, comprising: mixing free azacarbene and azacarbene iron with a solvent according to the ratio, then adding a phase transfer catalyst and a hydrogen donor to continue mixing, then adding phosphoric acid and The emulsifier is mixed to obtain the catalyst composition.
- phase transfer catalyst and the hydrogen donor before adding the phase transfer catalyst and the hydrogen donor to continue mixing, it also includes adding styrene tar for mixing.
- the present invention also proposes an application of the above-mentioned catalyst composition or the catalyst composition prepared by the above-mentioned preparation method in treating heavy oil.
- the beneficial effects of the present invention include: the phase transfer catalyst can bring the azacarbene iron into the heavy oil to contact with the oil, the proton is provided by the phosphoric acid, the emulsifier promotes the formation of water-in-oil in the heavy oil, which is beneficial for viscosity reduction, During the viscosity reduction process, the heavy oil releases metal ions complexed with it, and the metal ions form stable carbon-metal bonds with free azacarbene to obtain a stable complex, which undergoes a chemical reaction with azacarbene iron.
- Fig. 1 is the chemical structure identification proton nuclear magnetic resonance spectrogram of free azacarbene of the present invention
- Fig. 2 is the hydrogen nuclear magnetic resonance spectrogram of the chemical structure identification of azacarbene iron of the present invention.
- This specific embodiment provides a catalyst composition, according to mass percentage, including components: free azacarbene 1-4wt%, azacarbene iron 1-2wt%, phase transfer catalyst 15-30wt%, hydrogen donor 1-5wt%, phosphoric acid 5-10wt%, emulsifier 0.5-1wt%, and the rest are solvents, 100% in total; the hydrogen donor is methanol; the solvent is benzene; the emulsifier is Span 80;
- the phase transfer catalyst is a quaternary ammonium salt; further, the quaternary ammonium salt includes one or both of benzyltriethylammonium chloride and ammonium bromide.
- the catalyst composition further includes 5-10% styrene tar.

Description
本发明涉及稠油的降黏开采技术领域,具体涉及一种催化剂组合物及其制备方法和应用。
稠油黏度高、凝点高以及在地层中流动性差等特点,导致其难以采用常规方法进行有效开采。目前,稠油开采技术主要包括冷采技术、热采技术以及冷采与热采相结合的复合开采技。而在这些开采技术当中,以注蒸汽为主的热采技术应用最为广泛。
为了保证注空气采油过程中的安全性和提高采油过程的经济性,西南石油大学课题组于2002年提出了稠油油藏注空气低温催化氧化采油技术,该技术是在油藏条件下注气开采稠油的过程中,注入合适的催化剂,提高原油低温氧化速率,使耗氧增加并放热,同时形成烟道气或氮气辅助外注高干度蒸汽提高稠油采收率,有效提高地层能量、环境友好、成本低和热利用率高等特点。但是,稠油注空气低温催化氧化技术的安全性问题一直是学术界关注的焦点,尤其是生产井的安全,必须保证当空气突破时,采出气中O
2的浓度低于***的安全阈值(5%)。为此,目前趋势是将氧化源O
2替换成有机过氧化氢化合物、H
2O
2、KIO
4、NaIO
4等,在加入或者不加入溶剂的条件下,辅以催化剂。但是,现有的稠油开采用催化氧化的催化剂及其降黏剂仍然存在催化降黏效率低,降黏后的稠油中重质组分含量仍然较高的问题。
目前常用的稠油注空气低温催化氧化催化剂如油溶性金属盐、纳米金属催化剂和双功能催化剂等,它们都不同程度存在催化效果 低、易团聚、制备成本高等问题,解决该技术问题的关键在于获得合适的低温氧化降黏剂。
发明内容
本发明的目的在于克服上述技术不足,提供一种催化剂组合物及其制备方法和应用,解决现有技术中催化剂成本高降黏效果不佳的技术问题。
为达到上述技术目的,本发明的技术方案提供一种催化剂组合物及其制备方法和应用。
本发明提出一种催化剂组合物,按照质量百分比计算,包括:游离氮杂卡宾1-4wt%,氮杂卡宾铁1-2wt%,相转移催化剂15-30wt%,供氢剂1-5wt%,磷酸5-10wt%,乳化剂0.5-1wt%,其余为溶剂,总计100%。
进一步地,还包括苯乙烯焦油5-10%。
进一步地,所述供氢剂为甲醇。
进一步地,所述溶剂为苯。
进一步地,所述乳化剂为司盘80。
进一步地,所述相转移催化剂为季铵盐。
进一步地,所述季铵盐包括所述季铵盐包括苄基三乙基氯化铵和溴化铵中的一种或者两种。
本发明还提出一种上述催化剂组合物的制备方法,包括:按照配比,将游离氮杂卡宾和氮杂卡宾铁与溶剂混合,之后加入相转移催化剂和供氢剂继续混合,之后加入磷酸和乳化剂混合得到所述催化剂组合物。
进一步地,在加入所述相转移催化剂和所述供氢剂继续混合之前还包括加入苯乙烯焦油进行混合。
此外,本发明还提出一种上述催化剂组合物或者上述制备方法制备得到的催化剂组合物在处理稠油中的应用。
与现有技术相比,本发明的有益效果包括:相转移催化剂能够将氮杂卡宾铁带入稠油中与油接触,由磷酸提供质子,乳化剂促进稠油形成油包水利于降黏,降黏的过程中稠油释放出与其络合的金属离子,金属离子与游离氮杂卡宾形成稳定的碳-金属键并得到稳定的络合物,该络合物与氮杂卡宾铁一起发生化学反应进行降黏,降黏稠油的同时可将稠油释放的金属离子加以利用反作用于降黏,如此只需要较少的氮杂卡宾铁和游离氮杂卡宾即可实现对稠油快速且高效的降黏,经过6h降黏处理,对稠油的降黏率可高达90%以上。

对比例4
本对比例提出的催化剂组合物与实施例5的区别在于不含游离氮杂卡宾和氮杂卡宾铁,具体地,按照质量百分比计,包括:相转移催化剂苄基三乙基氯化铵20wt%,供氢剂甲醇3wt%,磷酸5wt%,乳化剂司盘80 0.6wt%,苯乙烯焦油5wt%,其余为溶剂苯,总计100%。
应用例
将实施例1-7及对比例1-3提出的催化剂组合物用于处理开采自吐哈的稠油为反应物(50℃下,黏度为95650mPa·s);具体地,先将稠油与水按照质量比7:3混合,之后按照催化剂组合物的添加量为所述稠油质量的1.0%向稠油中加入所述催化剂组合物并在60℃下进行降黏,检测并获取降黏4h、6h和8h的降黏率。
测定稠油的黏度值,评价催化剂的催化性能。降黏率计算公式为Δη(%)=((η0-η)/η0)×100%,η0和η分别指代反应前和反应后的 油样黏度,单位为mPa·s;降黏结果如表1所示。
表1实施例1-7及对比例1-3不同时间下对稠油的降黏结果
从表1可以看出,实施例1-4经过8h的降黏后降黏率高达90%左右,实施例5-7因为加入了乙烯焦油提高了稠油的流动性,明显加速了降黏速度,只需要6小时,降黏率可高达90%左右;而对比例1-2的降黏率很低,这可能是因为对比例中氮杂卡宾铁或者游离氮杂卡宾的含量较低,单独的少量氮杂卡宾铁和游离氮杂卡宾不利于降黏;另外实施例1-7的重质组***解为轻质组分的占比高达70%以上,明显高于对比例1-3;对比例1-3也进一步说明了本发明提出 的催化剂组合物的降黏效果是各组分配合实现的。
以上所述本发明的具体实施方式,并不构成对本发明保护范围的限定。任何根据本发明的技术构思所做出的各种其他相应的改变与变形,均应包含在本发明权利要求的保护范围内。
