海上探井特稠油热采测试技术研究及应用

摘要

In view of the unconsolidated testing formation and extra-heavy oil in PLA-2 reservoir, Bo-hai bay, and its drilling platform conditions, the thermal injection technology, thermal injection parameter optimization and test string optimization were researched, resulting in a set of test techniques of thermal recovery in exploration wells with extra-heavy oil. By their successful applications, the extra-heavy oil reservoirs can be actually identified with a lower cost and a higher time efficiency. Such thermal recovery testing in multiple fluids may open a new way to test offshore exploration wells in extra-heavy oil fields.%针对渤海PLA-2特稠油油藏测试目的层储层疏松、油稠的特点以及钻井平台的作业条件,开展了注热工艺、注热参数优化、测试管柱优化等方面的研究,形成了一套探井特稠油热采测试技术,并实践获得成功,实现了低成本、高时效并真实地认识特稠油油藏.多元热流体热采测试技术的成功应用,为海上特稠油油田探井测试开辟了新思路.
