| 摘 要： | 套保油田为普通稠油油藏，其开发的难点是常规冷采产能低、递减快，蒸汽吞吐开采注入压力过高破坏隔层导致底水上窜、注入压力过低不能保证注入蒸汽质量导致开采效果差。因此开展出砂冷采试验，经研究及现场试验形成了较完善的配套工艺技术，出砂冷采在套保油田白92块工业化应用，单井日产油达到10～30m^3／d，为常规冷采产量的10～20倍。

| Abstract: | Taobao oilfield is one conventional heavy oil reservoir. It was difficult for this oilfield to effectively develop due to low productivity and fast decline for conventional cold production, and bottom water breakthrough, which was resulted by too high injection pressure damaging barrier beds during huff-and-puff. Therefore, the tests of cold production with sand inflow were implemented , and the improved matched techniques and technology were developed based on the research and field tests. The cold production with sand inflow has been commercially applied in Block 92 of Taobao oilfield with the daily single well oil production of 10-30mVd, which was 10-20 times of the conventional cold production. |
