Development and Appraisal of Computer Software for Optimization of Particle Size of Temporary Plugging Agent

No. 81, Xinggong Xi Dajie, Sanhe City, Hebei 065201, china

摘要

摘要: 暂堵颗粒粒径分布的优化是保护储层暂堵技术的关键。为方便井场施工操作,以Alfred模型为基础,构建了钻井液暂堵颗粒理想充填分布模型,并以VB.NET为平台开发了颗粒粒径优化软件。根据输入的目标地层参数,软件自动给出相应的暂堵颗粒级配方案。室内通过PPT实验考察了二元及三元颗粒级配匹配度与滤失量的关系,验证了2者的反相关性。采用0.38~0.42μm²人造岩心进行了储层保护实验,进一步验证了匹配度与渗透率恢复值的正相关性。室内验证实验表明,暂堵颗粒粒径经软件优化后能有效降低储层伤害,可应用于完井、修井作业的施工方案设计。

Abstract: Optimization of the particle size distribution of temporary plugging agent plays a key role in reservoir protection. An ideal packing model for temporary plugging agent particle size optimization was developed based on the Alfred Model, and a software was developed on the VB.NET platform. This software calculates the optimized particle size distribution using the parameters of the target formation. The relationship between binary and ternary particle size compatibility and filter loss was examined through PPT experiment, and the inverse correlation of the two was verified. Positive correlation between the degree of match and permeability recovery was verified through laboratory experiment on artificial cores of 0.38 μm²-0.42 μm². Laboratory experiment showed that particle sizes optimized using the developed software effectively reduced reservoir damage, and the optimization results can be used in well completion and workover designs.
