摘要
针对准噶尔盆地西缘春风油田薄浅层超稠油油层单一、多轮次水平井蒸汽吞吐后产量快速递减的情况,开展了水平井蒸汽驱开发先导试验。在对油藏特征、有利因素、不利因素分析基础上,从蒸汽驱方案要点、数值模拟优化、高干度注汽、泵提液技术、气窜封堵技术等方面对先导试验进行系统的全面研究。研究表明,水平井蒸汽驱开发先导试验可有效提高春风油田薄浅层超稠油开采效果,为春风油田水平井蒸汽驱开发提供了有利的技术支持。
In the Chunfeng oilfield at the western margin of Junggar Basin,the thin shallow super heavy nil reservoir is simple and the production declines rapidly after multi-cycle steam huff and puff via horizontal well.In this case,a pilot test is made for development with horizontal well strum drive technique.Based on the analysis of reservoir characteristics,beneficial factors and adverse factors,a systematic and comprehensive study is made to the pilot in view of elements of steam drive scheme,optimization of numerical simulation,high- dryness sleam injection,fluid pumping technique and blocking of gas channeled.The results show that the pilot test can help to effectively improve the receivery of thin shallow super heavy oil in the Chuanfeng Oilfield,proving a powerful technical support to the development with horizontal well sleam drive in the oilfield.
