3～5m特薄层超稠油油藏蒸汽吞吐厚度界限研究

Thickness Limit of Huff and Puff in Superheavy Oil Reservoir of 3 to 5m Thick

摘要: 在分析研究井楼、古城油田 3～ 5m特薄层超稠油油藏地质和开采特点的基础上 ,根据特薄层稠油单井蒸汽吞吐经济极限累积产量研究结果 ,系统研究了 70× 10 0m和 10 0× 141m井距条件下特薄层超稠油油藏返层兼采、一套层系开发和两套层系开发的蒸汽吞吐开采厚度界限条件。该技术可用以指导 3～ 5m低品位超稠油油藏经济有效地合理开发

Abstract: Geological and development characteristics of the superheavy oil reservoirs of 3 to 5m thick are analyzed in Jinglou and Gucheng oilfields. The thickness limit of huff and puff in extraordinary hin superheavy oil reservoirs with well spacing of 70×100 m and 100×141 m is systematically studied based on the economic accumulative production of single well huff and puff. This technology can be used to guide economic, effective and rational development of superheavy oil reservoirs of 3 to 5m thick.
