海洋石油完井技术现状及发展趋势

Current situation and development of offshore completion technology

合理选择最佳的完井方式是充分发挥油井潜力、有效开发油田的一项重要工作。介绍了海上油气田在完井防砂和智能完井等几个方面先进技术的应用现状,并根据海上勘探开发的需求,提出海上完井技术应针对边际油田、高温高压和深水开发以及稠油开采等课题开展研究和先导性试验。同时,结合完井技术的现场推广情况,建议开展完井工具自主创新和消化吸收,实现工具的自主产权化。

Rational selection of optimal well completion methods is critical in fully exerting oil well potential and effectively developing oil fields. In this paper, the application of advanced theologies to sand control and intelligent completion of offshore oil and gas fields is introduced. To meet the requirement of offshore exploration and development, the development tendency of offshore completion technologies is proposed. Research and pilot test are conducted on marginal oilfields, deep development with high temperature and high pressure, and heavy oil exploitation. Meanwhile, combined with field application of well completion technology, independent innovation and absorption of completing tools are supposed to be carried out to realize independent property right transformation.
