摘　　要：综合应用SAGD蒸汽腔发育监测技术发现,风城双水平井SAGD试验井蒸汽腔发育呈现非标准化、非均衡性和上升速度缓慢的特征。在掌握了影响SAGD蒸汽腔发育主要因素的基础上,针对风城SAGD特殊汽腔发育存在的问题,开发了一系列蒸汽腔发育改善治理技术,包括注采管柱工艺、生产调控、关键操作参数设计。现场应用结果表明,该技术系列有效改善了蒸汽腔发育程度,油藏动用程度和产油速度得到显著提高,现场应用效果良好。It is found by the comprehensive application of SAGD steam chamber growth monitoring technologies that the steam chamber growths present non-standardization, non-equitability and slow speed upward at the SAGD test on the dual horizontal wells in Fengcheng Oilfield. Based on the understanding of the main factors which af- fect the SAGD steam chamber growth, a series of technique are developed to improve the SAGD steam chamber growth, including the injection and production tubing string technique, the production-control technique and key operation parameter design etc. The field application shows that the series of the technology have effectively improved the steam chamber growth degree, the reservoir producing degree and the oil-producing speed have been improved greatly, a good field application effect are obtained.
