复杂断块油藏蒸汽吞吐开发效果分析

由于在蒸汽吞吐开发过程中要受到多种因素的影响,而且生产井处于断层和油水边界附近,所以层间水复杂小断块稠油油藏的开发难度较大.作者以新庄油田57和67断块稠油开发为例,通过分析判断,分别研究了层间水侵入井和正常生产井的开发特点及影响因素,提出见层间水的判断方法.在对各类生产井生产特点分析的基础上,研究该类油藏开发特点及影响因素,对提高相同类型的稠油油藏的开发具有参考价值.

Analysis of Efficiency of Huff and Puff in Reservoir of Complex Small Fault Flock

Effected by many factors during huff and puff,the reservoir of edge water invasion and complex small fault block,the producing wells which are located in the neighborhood of the fault trace and oil-water contact,are quite difficult for development.The production of NO57 & 67 fault block in Xinzhuang oilfield is taken as an example to analyse the developing complexity and difficultly,which concludes the producing characteristics,effect factors of normal production and flooded well,Meanwhile,a simple method is put forwared to judge the water invasion based on the conclusion of various kinds of producing wells.It has important meaning to analyse the developing characteristics,effect factors and bring forward refence for the development analysis of the same kind of reservoir.
