摘要
水平井试采是目前一项逐渐成熟的、有效提高油气产能的技术途经。但因水平井特殊的井身结构,使得在水平井段进行井下施工操作具有独特的施工环境,试油和开采过程中有别于直井或斜井的常规试油工艺。使用改进的水平井可捞式桥塞,克服了水平井段普通桥塞不易坐封和打捞困难的缺憾,对水平井段封层和分层试油及现场类似操作具有一定的借鉴作用。
Oil testing and recovering in horizontal well is one technical way that is gradually ripe and effectively improves oil and gas productivity at present.But because of special casing program of horizontal well,it must have unique construction environment during constructing at horizontal interval,and is different from conventional oil testing tech in straight well and inclined well during oil production testing and recovering.By improving plug which can be fished in horizontal well,it overcomes the regret that it is difficult to set and fish by using ordinary plug at horizontal interval,which supply reference for oil production testing about plugging player and separating layer and similar operation in field.
