- 摘要:
- 针对长庆油田油藏埋藏深、低渗、低产、大井组、滚动开发、快速开发的特点，油气集输采用油气混输工艺可实现集输系统的优化和伴生气充分回收利用。文章从定压阀回收油气混输工艺、同步回转油气混输工艺、增压点油气混输工艺等对该技术进行了介绍，文章最后还对油气混输工艺技术的发展进行了展望。
The storage tank area for first-phase of Tianjin LNG project is located in special geological condition.The original foundation treatment scheme,i.e.plastic drainage sheet + waterproof wall + well point drainage + self-weight load by secondary backfill,encounters difficulties,so that the new foundation treatment scheme,i.e.holing with long spiral machine + stroked vibrating cast-in-place sand pile + waterproof wall + well point drainage + self-weight load by secondary backfill,is proposed.The construction procedure,technical and quality inspection requirements of the new foundation scheme are illustrated in this paper,and its applicability as well.2013,3(3): 59-63 收稿日期：2012-5-31DOI：10.3969/j.issn.1001-2206.2013.03.016作者简介：郭刚(1982-)，男，四川达州人，2007年毕业于中国石油大学(华东)油气储运专业，硕士,现从事油气田地面工程规划设计工作。参考文献：
