乳液压井液论文：乳液压井液抗气侵能力低滤失量储层保护

1、乳液压井液论文：乳液压井液抗气侵能力低滤失量储层保护【中文摘要】现在油田生产作业中用到的压井液种类很多，但现场应用针对低压区块密度小于 1 的乳液压井液，目前还没有考虑滤失 性。作业时由于有机分子或水的侵入储层，同样会造成储层污染，严重 时会出现减产的现象。吉林油田红岗区块压力系数小于1,井下温度为 40C,因此适合吉林油田红岗区块的压井液必须具备低密度低滤失 特性。本文结合红岗气田储层的基本特征，对储层进行敏感性评价，并且通过对岩心分析、铸体薄片分析，总结储层的敏感性，得出压井液 体系设计原则。压井液体系的研究是以水包油乳液为基础，筛选乳化剂、防膨剂、增粘剂、降滤失剂等，以乳液压井液的滤失量

2、、粘度为 标准,确定乳液压井液的最佳添加剂。通过调整油水的比例和优化添 加剂的浓度，得出不同密度的压井液体系配方。室内通过测定压井液 体系的抗气侵能力、沉降稳定性、储层伤害性等，来评价乳液压井液 体系的综合性能和保护储层的能力。【英文摘要】 Nowthere are manykinds of well control fluid inmanufacturing of oil well, but the well control fluid which is aimed atlow-pressure area and specific gravity is smaller tha n one d
