2C复合吞吐技术在洲城油田高含水油井的应用
|
摘要
2C复合吞吐技术是在CO_2吞吐技术的基础上进行创新优化后形成的一项新技术。通过室内试验和研究,优化出洗油剂、CO_2吞吐参数,并在洲城油田洲20井开展现场试验,试验后初期含水下降40%、日增油13 t,目前已增油301 t,效果显著。试验结果表明,此项技术具有投资少和见效快等特点,是提高高含水油井产量和采收率的有效措施,值得在高含水油井推广应用。
CO_2compound huff and huff compound huff and puff technology is a new technology, which is innovated and optimized from CO_2 compound huff and huff technology. Through laboratory test and research, the parameters of washing oil agent, CO_2 huff and puff were optimized, and the test was conducted in well Zhou-20 of Zhoucheng oilfield. The field tests show that, in the early stage, water cut declines 40 %, daily incremental oil production is 13 ton. And up to now, the cumulative incremental oil production is 301 ton. In addition, having the advantages of less investment and fast effect, this technique is an effective measure to improve production and recovery ratio of high water cut production wells. Accordingly, this technique is worth popularizing.
