水平井分段压裂生产剖面测试技术进展与展望

针对目前水平井分段压裂生产剖面测试存在的各类问题,通过对分布式光纤、生产测井和示踪剂监测三大测试技术原理、适应性等进行分析对比,明确技术优势与不足,并对各项技术的发展趋势进行展望,进一步明确了水平井剖面测试技术的发展方向。研究表明:分布式光纤监测技术性能稳定、安装方便,但存储量大、无法完成定量解释;生产测井技术测试精度高,但适应性受到一定程度限制;示踪剂测井种类较多,各有利弊;剖面测试技术可从装备和数据解释方面进行深化研究。该研究可为现场的测试选择提供技术参考,也为后续的技术发展提供方向。

Progress and Prospect of Production Profile Testing Technology for Staged Fracturing in Horizontal Wells

In view of the various problems existing in the current production profile testing for horizontal well staged fracturing, the development direction of horizontal well profile testing technology is further clarified by analyzing and comparing the technical principles and adaptability of such three testing technologies as the distributed optical fiber, the production logging and the tracer monitoring to identify advantages and disadvantages of these technologies and providing an outlook on the development trend of each technology. The research shows: The distributed optical fiber monitoring technology is stable and easy to install, but the storage capacity is large and cannot be interpreted quantitatively; the production logging technology has high precision, but it is not applicable in some cases; the tracer logging involves many types, each with its own advantages and disadvantages; In the future, the in-depth research on logging technology can be carried out from the aspects of technical equipment and data interpretation. This research can provide some technical reference for the field test selection, and also provide some new perspectives for the follow-up technical development.
