油层保护技术是一项涉及多学科、多部门、多专业的系统工程。综合评价地层损害要分析对比一系列评价参数 ,往往需要较长的时间。在孤东三区的应用表明 ,运用采油工程入井液标准确定及地层伤害诊断专家系统 ,可以方便、快捷、科学地对伤害因素进行分析诊断 ,并提出相应的预防和处理措施。该系统包括盐敏、碱敏、颗粒含量、颗粒直径、表面张力、细菌含量等 6个实验数据库 ,1个油层伤害诊断知识库 ,1个入井液质量标准确定模块和 1个专家咨询模块 Reservoir protection technology is a multidisciplinary, multi-sectoral and multi-disciplinary systems engineering. Comprehensive evaluation of formation damage To analyze and compare a series of evaluation parameters, it usually takes a long time. The application in Gudong three districts shows that it is convenient, quick and scientific to analyze and diagnose the injury factors and to put forward the corresponding prevention and treatment measures by using the standard of well drilling fluid identification and formation damage diagnosis expert system. The system includes six experimental databases including salt sensitivity, alkali sensitivity, particle content, particle diameter, surface tension and bacteria content, a reservoir diagnosis knowledge base, a module for determining the quality of incoming fluid and an expert consultation module
