摘要
高升油田为中深层稠油油藏，注蒸汽开采一般井底蒸汽干度较低，目前仍以蒸汽吞吐生产为主。分析了高升油田高三块目前井网密度和生产现状，通过数值模拟方法和油藏热平衡法，以目前井网、井距为基础，系统地对注蒸汽吞吐井网密度进行了研究，其结果表明：合理地钻加密吞吐井，可经济有效地提高采出程度。
For the medium deeply buried heavy oil reservoirs of Gaosheng oil field, the main recovery method is still steam huff and puff due to the comparably poor quality of steam at bottom hole during oil recovery by steam injection. This paper analyses the current well spacing and production performance of Gao-3 block in Gaosheng oil field and presents the result of studying rea sonable well spacing of cyclic steam stimulation by means of numerical simulation and the calculation of reservoir heat ba lance. This result indicates that the current oil recovery can be increased effectively and economically by drilling proper in fill wells for cyclic steam stimulation.
