基于非侵入式温度变送器的稠油吞吐井测温系统设计应用

Design and Application of Temperature Measurement System for Heavy Oil Steam Stimulation Wells Based on Non-intrusive Temperature Transmitters

温度是稠油吞吐开发中分析油井生产动态、研判注入蒸汽指标、识别井间汽窜干扰的核心参数,直接影响着开发效果。早期开发的稠油区块井场温度数据录取主要采用人工抄录方式,存在着数据采集工作量大、精度低、时效性差,生产异常难以及时发现等诸多不足。针对传统的“RTU+仪表”单井自动化建设模式在稠油吞吐开发区块无法大规模推广的问题,提出了利用一种非侵入式温度变送器与远程自动选井计量控制相结合的测温系统设计思路,实现稠油吞吐井温度自动采集上传、异常建模分析,有效提高数据采集频次、提升数据质量、拓宽应用场景,形成一种低成本、易实施、性能优的稠油吞吐井温度监测建设模式。

Temperature is the core parameter for analyzing oil well production performance,evaluating injection steam indicators,and identifying inter well steam channeling interference in heavy oil stimulation development,which directly affects the development.The temperature data acquisition of early developed heavy oil block well pads mainly adopt manual recording,which has many shortcomings,such as large data collection workload,low accuracy,poor timeliness,and difficulty in timely detection of production abnormalities.In response to the problem that the traditional“RTU+instrument”single well automation construction mode cannot be widely promoted in heavy oil stimulation development blocks,a temperature measurement system design scheme that combines a non-intrusive temperature transmitter with remote automatic well selection measurement control to achieve automatic temperature collection and uploading is proposed,to achieve abnormal modeling and analysis of heavy oil stimulation wells,and to effectively improve data collection frequency,to improve data quality,and to expand application scenarios,to develop a low-cost,easy to implement and high-performance temperature monitoring construction model for heavy oil stimulation wells.
