由大港石油管理局定向井技术服务公司设计并提供技术服务,钻井工程公司32670钻井队施工的张17—1大位移多目标定向井,于1991年2月16日钻达设计层位交井。经试油,?4mm油嘴日产原油14t、天然气1397m~3,获得了较好的经济效益。该井是我国目前水平位移最大的一口定向井,钻达3个目标点。钻进过程中使用了无线随钻测量系统,全井定向一次成功,下了2层大尺寸技术套管,稳斜井段长,井身剖面符合率高,在井斜48.5°井段取心6.70m,收获率100%。该井还采用了项目管理、技术监督体制。本文介绍了该井实钻过程中的一些做法,供同行参考。
The Dagang Petroleum Administration directional well technical service company designed and provided technical services. Drilling engineering company 32670 drilling team construction Zhang 17-1 large displacement multi-directional directional well, drilling on February 16, 1991 drilled to design the level of well. The test oil,? 4mm nozzle Nissan crude oil 14t, natural gas 1397m ~ 3, get better economic benefits. The well is currently the largest horizontal displacement in China a directional well, drilling up to 3 target points. During the drilling process, a wireless MWD measurement system was used. The whole well was successfully oriented once and a large two-layer technical casing pipe was installed. The length of the steadily inclined well section was high and the coincidence rate of the wellbore profile was high. 6.70m, the harvest rate of 100%. The well also adopted a project management, technical supervision system. This article describes some of the drilling practice in this well for peer reference.
