浅薄层稠油油藏注蒸汽开采规律研究

Study of Recovery Law of steam Injection in Thin Thickness Heavy Oil Reservoir

通过对河南井楼油田零区试验区注蒸汽开采的试验资料及生产区蒸汽吞吐大量数据的统计分析，结合数值模拟，本文提示出浅薄层稠油油藏注蒸汽开采规律：尽管油层纵向驱替状况好向驱替状况好，采油速度和采出程度高，但单井日产油量、周期产油量和油汽比仍较低，产量递减快。

The analysis of the production data of Jinglou Oilfield of Henan and one of its pilotareas, Opilot,reveals the recovery law of cyclic steam simulation and steam flooding in thin thickness heavy oil reservoir: While the vertical displacement is efficient and the recovery rate and percentage are high,the oil production rate per well,cyclic oil production and oil-steam ration are low,and oil production declines fast.
