吉林油田欠平衡钻井技术研究

摘要

The Jilin oilfield found Changling faulted contains the large reserves natural gas by underbalanced drilling technology in Changshen 1 wells ,for the expansion of the results of exploration ,and improve the efficiency ,promote the underbalanced drilling technology .Technology promotion and improvement make the drilling speed raise sharply ,gas reservoirs protection is very effective ,promoting the promotion and implementation of underbalanced drilling supporting technology .%对吉林油田在长深1井应用欠平衡钻井技术进行了研究，发现了长岭断陷蕴含丰富的天然气，为扩大勘探开发成果，提高勘探效率，推广应用欠平衡钻井技术。通过欠平衡技术推广与完善，钻井速度大幅提高，气藏保护效果显著，促进了欠平衡钻井配套技术的推广实施。
