Description
技术领域 technical field
本发明属于缓蚀剂领域，涉及一种控制二氧化碳与高矿化度腐蚀的缓蚀剂组合物。The invention belongs to the field of corrosion inhibitors and relates to a corrosion inhibitor composition for controlling carbon dioxide and high salinity corrosion.
背景技术 Background technique
随着油田开发的深入，二氧化碳与高含水、高矿化度组成混合腐蚀介质的金属腐蚀逐渐加重，腐蚀、结垢直接威胁了油田的安全稳定生产。西北某地的油井水质分析报告为例：某区块16口油井产出水的水质分析结果显示，所有水质属于NaHCO3型，HCO3 -含量高，pH值在8～9之间，同时，Ca2+离子高达1000mg/L，这种水，极易产生腐蚀与结垢，因此研制一种能控制二氧化碳与高矿化度的混合腐蚀与结垢的物质和方法，对油田安全、稳定生产是非常重要的。缓蚀剂是控制二氧化碳腐蚀、结垢的一种简便，经济，有效的重要物质和方法之一，缓蚀剂的缓蚀效率与钢材料种类、腐蚀环境，地层的温度有密切的关系，西部油田一般油井转井深度都超过了5000米，地下环境复杂，温度较高，矿化度高，都采用高含Cr、Ni、Mo钢。目前所采用的缓蚀剂，难以适应油田的情况，难以取得满意的效果，因此，需要研制具有多种功能缓蚀与阻垢的组合物，以实现控制二氧化碳腐蚀与结垢的目的。With the deepening of oilfield development, the corrosion of metals in the mixed corrosive medium composed of carbon dioxide, high water content and high salinity is gradually aggravated. Corrosion and scaling directly threaten the safe and stable production of oilfields. Take the water quality analysis report of an oil well in a certain place in Northwest China as an example: the water quality analysis results of 16 oil wells in a certain block show that all the water quality belongs to NaHCO 3 type, the HCO 3 - content is high, and the pH value is between 8 and 9. At the same time, Ca 2+ ions are as high as 1000mg/L. This kind of water is very prone to corrosion and scaling. Therefore, a material and method that can control the mixed corrosion and scaling of carbon dioxide and high salinity is developed, which is safe and stable for oilfield production. is very important. Corrosion inhibitor is one of the simple, economical and effective important substances and methods to control carbon dioxide corrosion and scaling. The corrosion inhibition efficiency of corrosion inhibitor is closely related to the type of steel material, corrosion environment and formation temperature. Generally, oil wells in oilfields have a transition depth of more than 5,000 meters. The underground environment is complex, the temperature is high, and the degree of salinity is high. Steels with high Cr, Ni, and Mo content are used. The corrosion inhibitors currently used are difficult to adapt to the conditions of oilfields, and it is difficult to achieve satisfactory results. Therefore, it is necessary to develop compositions with multiple functions of corrosion and scale inhibition to achieve the purpose of controlling carbon dioxide corrosion and scaling.
发明内容 Contents of the invention
本发明的目的是为克服现有缓蚀剂的不足，解决西部油田二氧化碳腐蚀与结垢的问题，延长油田设备的使用寿命，保证油田的安全、稳定生产。提供一种控制二氧化碳与高矿化度腐蚀的缓蚀剂组合物。在高矿化度含有HCO3-与氧气的腐蚀环境中，极易产生结垢与腐蚀，尤其是容易产生垢下的穿孔腐蚀。因此，需要解决结垢与腐蚀的双重问题，在油田的含水中，一般钙离子容易和水中的碳酸根结合，形成碳酸钙垢，解决结垢，就是设法不使形成垢，为此，需要络合住水质中的钙离子。基于这样的想法，在配方的设计上，就需要考虑采用一定的措施控制钙离子的浓度，在破坏结垢方面，磷酸盐具有比较理想的效果，为此，沿着这个思路我们寻找到药物中间体中含磷的化合物，它不仅有阻垢作用，也有良好的缓蚀效果，见其分子式：The purpose of the invention is to overcome the deficiency of existing corrosion inhibitors, solve the problems of carbon dioxide corrosion and scaling in western oilfields, prolong the service life of oilfield equipment, and ensure the safe and stable production of oilfields. A corrosion inhibitor composition for controlling carbon dioxide and high salinity corrosion is provided. In the corrosive environment containing HCO 3 - and oxygen with high salinity, scale and corrosion are very easy to occur, especially the perforation corrosion under the scale is easy to occur. Therefore, it is necessary to solve the dual problems of scaling and corrosion. In the water contained in the oil field, generally calcium ions are easy to combine with carbonate radicals in the water to form calcium carbonate scale. To solve scaling is to try to prevent the formation of scale. Hold calcium ions in the water quality. Based on this idea, it is necessary to consider certain measures to control the concentration of calcium ions in the design of the formula. In terms of destroying scaling, phosphate has a relatively ideal effect. Phosphorus-containing compounds in the body, it not only has scale inhibition effect, but also has good corrosion inhibition effect, see its molecular formula:
