以专家知识和现场经验为基础，将专家系统技术应用于稠油开发领域的蒸汽吞吐中，开发了蒸汽吞吐的专家系统（ＥＳＳＳ）。通过访问现场专家，搜集现场数据及查阅文献等手段，收集了大量有关蒸汽吞吐工艺的知识。将这些知识进行整理、分析、综合，建立了蒸汽吞吐专家系统的知识库。在知识库中，以产生式规则来表示知识，利用树形结构组织知识库；采用面向目标的推理技术。该专家系统包括三个基本的功能模块，能用来筛选宜于采用蒸汽吞吐开发的稠油油藏，选择基本注汽工艺参数以及进行注汽前、后的指标预测。该系统有简单、直观的菜单提示，操作方便简单。利用部分现场资料进行了检验，与现场资料吻合较好，说明该系统具有一定的可靠性和实用性
Based on expert knowledge and field experience, expert system technology is applied to steam huff and puff in the field of heavy oil development, and an expert system for steam stimulation (ESSS) has been developed. By accessing field experts, collecting field data and consulting literature, a great deal of knowledge has been collected on steam huff and puff processes. This knowledge will be collated, analyzed, integrated, and established a steam hunter expert system knowledge base. In the knowledge base, the rules of production to represent knowledge, the use of tree structure to organize knowledge base; the use of goal-oriented reasoning technology. The expert system includes three basic functional modules, which can be used to screen heavy oil reservoirs that are suitable for steam stimulation development, select the basic steam injection process parameters and forecast the indexes before and after steam injection. The system has a simple, intuitive menu prompts, easy to operate. Using some of the field data for testing, and field data is consistent, indicating that the system has a certain degree of reliability and practicality
