摘要
针对单家寺单113块油田超稠油油藏原油密度大、粘度高、含胶质高、凝固点高和烷烃含量低的特点,提出了超稠油注入CO2改善超稠油开采效果的采油工艺技术。通过对超稠油油藏注入CO2开采的试验,研究超稠油注入CO2的影响因素,并对单113块进行了注入CO2蒸汽吞吐的矿场试验。试验效果表明,注CO2蒸汽吞吐对单家寺油田超稠油油藏的开发具有重要的指导意义。
The superheavy oil reservoirs of Block Shan 113 show the characteristics of great density,high viscosity,large content of resin,high freezing point and low fraction of parrffin hydrocarbons.CO2 injection is recommended to improve the recovery effect of this block.Experiments were performed to study different influencing factors on the recovery effect and field tests of CO2 injection and steam stimulation were also done.The recovering mechanism of CO2 injection is presented in this paper and the field test results demonstrate the importance of CO2 injection to the development of Reservoir Shanjiasi.
