王庄油田超稠油蒸汽吞吐进入高轮阶段后,存在着吞吐效果变差,周期产油量下降、吨油成本上升等问题。在认真分析了影响高轮井开发效果的主要因素后,有针对性地提出并采取了组合式吞吐、间歇蒸汽吞吐、多元式吞吐等多种技术对策,打破了以往单一的吞吐模式,提高了热利用率,改善了高轮井吞吐效果。这些技术措施对其它超稠油和稠油油藏开发是有借鉴作用。
Wangzhuang Oilfield super heavy oil steam huff and puff into the high stage, there is the huff and puff, the periodic decline in oil production, tons of oil costs rise and so on. After carefully analyzing the main factors affecting the development effect of high-round-well, the paper put forward and adopted a series of technical measures such as combined throughput, intermittent steam throughput and multiple throughput, etc., breaking the previous single throughput mode and improving Thermal utilization, improved high round well throughput. These technical measures are of reference for the development of other ultra-heavy oil and heavy oil reservoirs.
