摘要
杜229断块兴V组是典型的边底水油藏,随着采出程度及吞吐轮次的增加,边底水波及范围和影响程度越来越严重。为落实来水方向及能量大小,在该区块的杜32-51-37和杜32-53-41井组进行化学示踪剂监测,基本上确定了边底水突破方向和推进速度。通过示踪剂监测资料,结合生产实际,分析认识杜229断块构造南部兴V组出水这一问题,提出了科学的堵、排水工作思路。该种方法首次在边底水问题上采用,为兴V组综合治理提供了依据。
Xing-V formation of block Du229 is a typical edge water reservoir. As the recovery percent of OOIP and steam stimulation cycles getting more, the conformance range and influence of edge and bottom water become increasingly serious. In order to understand the direction and energy of the water, chemical tracer monitoring has been conducted in well block Du32-51-37 and Du32-53-41, and the breakthrough direction and movement velocity of edge and bottom water are almost determined. According to tracer monitoring data, combining with production practice, the problem of water production from Xing-V formation in the south of block Du229 is analyzed, and a scientific thought of water plugging and draining is put forward. This method is applied to the problem brought by edge and bottom water for the first time, and provides basis for comprehensive treatment of Xing-V formation.
