用几个不同的开采方案对阿根廷ChihuidodelaSierraNegra油田的化学驱潜力进行了评价。在该油田进行了几年的大规模水驱 ,并且已经用地面设备重复利用采出盐水作为注入盐水。因此 ,无论从操作的观点还是从经济的观点来看 ,用采出盐水作为化学溶剂的添加水都是非常有利的。然而 ,地层盐水中含有大约 11× 10 4 ppm的固体总量和约 2 80 0 ppm的二价阳离子 ,这就使选择合适的表面活性剂相当困难。已经考虑采用三元复合驱 (ASP驱 )工艺 ,然而 ,大量的淡水以及在该油田安装软化设备的需要对该工艺的经济效益有不利的影响。本文将讨论新的阴离子表面活性剂的研制 ,这种阴离子表面活性剂在高矿化度中具有溶解性 ,并且当浓度低时 ,界面张力低。简要描述ChihuidodelaSierraNegra油田的开发史、表活剂的室内筛选和评价 ,包括界面张力性质、吸附、岩心评价 ,并且还要讨论化学驱动态。研制新表面活性剂的重要性在于 ,这种表面活性剂使得设备EOR项目得以实施 ,打消了由于需要进行水处理和处理费用的增加而被认为不经济的想法 Chemical potential of the Chihuidodela Sierra Negra field in Argentina was evaluated using several different mining options. Large-scale waterfloods have been carried out in the field for several years, and groundwater has been used as recovery brine for groundwater reuse. Therefore, it is very advantageous to use brine as a chemical solvent to add water, both from an operational point of view and from an economic point of view. However, the formation brine contains about 11 × 10 4 ppm of total solids and about 2 80 0 ppm of divalent cations, making it rather difficult to select a suitable surfactant. ASP flooding has been considered, however, the sheer volume of freshwater and the need to install softening equipment in the field adversely affect the economics of the process. This article will discuss the development of new anionic surfactants that have solubility in high salinity and low interfacial tension at low concentrations. A brief description of the history of the Chihuidodela Sierra Negra field, in-house screening and evaluation of surfactants, including interfacial tension properties, adsorption, core evaluation, and chemical-driven states. The importance of developing new surfactants is that this surfactant enables the EOR project of equipment to eliminate the idea of ​​being considered uneconomical due to the increased cost of water treatment and treatment required
