摘要
欠平衡钻井由于有利于发现和保护油气层、提高钻速、降低成本 ,减少井漏及压差卡钻等复杂情况 ,而受到人们的高度重视。在已知的三种欠平衡钻井流体中 ,泡沫流体由于比空气钻井更安全 ,比雾化钻井液或纯气体钻井所需的设备功率更低 ,净化井眼能力更强 ,因而越来越广泛地应用于欠平衡钻井中。利用泡沫流体进行欠平衡钻井 ,是一种较安全的钻井技术。文章介绍了泡沫流体的组成、性能、特点及作用 。
Under balance drilling is paid great attention to by people for it is favourable for discovering and protecting oil and gas reservoirs,raising drilling speed,reducing cost and lessening drilling lost circulation and differential pressure sticking.Among the known three kinds of under balance drilling fluids,the foam fluid is more and more widely used for under balance drilling.Use of foam fluid for under balance drilling is a relatively safe drilling technique.In this paper,the composition,property,characteristics and function of the foam fluid are presented,the common problems in foam fluid drilling are analyzed and some.proposals are put forward.
