Description
技术领域 technical field
本发明属于油田化学技术领域，具体涉及一种以卵磷脂为主剂的非离子型清洁压裂液。 The invention belongs to the technical field of oil field chemistry, and in particular relates to a nonionic clean fracturing fluid with lecithin as the main agent.
背景技术 Background technique
压裂液是在石油开采过程中，为了获得高产而利用液体传导力压裂流体层时所用的液体。卵磷脂非离子型活性剂是一类在水中不会电离而整个分子起表面活性作用的活性剂，由于它们一般抗盐、抗钙、抗酸、抗碱性强，又不易与常用的引力自由基相互干扰，且对储层的渗透率伤害小，故在压裂液中使用非离子型活性剂越来越多。常规的压裂液体系以瓜尔胶为稠化剂，在使用过程中往往由于破胶不彻底，破胶液残渣含量高，而对地层的渗透率伤害较大，通常达到20%以上，不利于油气层的保护，在使用过程中越来越受到局限。 Fracturing fluid is a liquid used in the process of oil extraction to use liquid conduction force to fracture fluid layers in order to obtain high yield. Lecithin non-ionic active agent is a kind of active agent that will not ionize in water and the whole molecule acts as a surface active agent. Because they are generally resistant to salt, calcium, acid, and alkali, they are not easy to be free from gravitational forces commonly used. The mutual interference between base and base, and little damage to the permeability of the reservoir, so more and more non-ionic active agents are used in fracturing fluids. Conventional fracturing fluid systems use guar gum as the thickener. During use, due to incomplete gel breaking and high residue content of the gel breaking fluid, the permeability of the formation is greatly damaged, usually reaching more than 20%. It is beneficial to the protection of oil and gas layers, and is more and more restricted in the use process.
