低荧光防塌沥青及低荧光特效封堵防塌降滤失剂的研制与应用

Development and Application of Low Florescence Anti-collapse Asphalt and Low Florescence Anti.collapse Filtration Reducing Agent

摘要:

研发了一种具有优良防塌效果的低荧光钻井液用井壁稳定剂，提高石油沥青磺化度，解决降低产品荧光级别的新工艺，突破因荧光干扰测录井导致油储层被误判、漏判的关键技术，磺化反应后期，引入提高产品综合性能的特种材料进行交联反应。介绍了低荧光防塌沥青LF—TEX-1及低荧光特效封堵防塌降滤失剂FSL-1的关键技术原理和生产工艺流程，并对这两种处理剂的性能测试结果进行了分析。实际生产应用表明，他们具有明显的封堵、降失水功能。

Abstract:

A low florescence wall-stabilizing agent for drilling fluid was developed. Technical principles and technological process of low florescence anti-collapse asphalt LF - TEX - 1 and low florescence anti-collapse filtration reducing agent FSL - 1 were introduced, and testing results showed these two products have good function of circulation lost control and filtrate reduction.
