关于聚合物铠装连续油管和钻进水平井用液动加载装置的试验研究

Experimental research on armored polymer coiled tubing and hydraulic feed for drilling horizontal well

摘要:

世界上钻井技术和方法很多，其中连续油管钻井是一项重要的油气井钻井技术，美国、加拿大使用较多，俄罗斯也在使用，取得了很好的社会经济效果。我国有这方面的设备也在使用。俄罗斯研发出来了聚合物钢丝铠装连续油管，其技术指标不亚于碳钢油管；设计出的液动加载装置，解决了水平井钻进摩擦阻力大、机械钻速低的难题。聚合物铠装油管和水平井钻进加载装置的研发成功，为连续油管钻井技术的扩大使用创造了有利条件。可以期望，或许可为我国未来煤层气和页岩气钻井的发展做出贡献，具有一定的实际意义，值得我们注意。

Abstract:

There are a lot of drilling technologies and methods in the world，among them coiled tubing drilling is an important oil and gas drilling technique, particularly for gas drilling. It has been used widely in USA, Canada, and also in Russia, leading to good technical and economical results. There are such coiled tubing units in China, and they are used. In Russia steel wire armored polymer coiled tubing has been developed and its technical characteristics are as good as those of carbon-steel coiled tubing. The designed hydraulic feed device has eliminated the problems such as high drag force, low penetration rate while drilling long horizontal wells. Combining of the armored polymer coiled tubing with the feed device creates favorable conditions for promoting the application of the technology. It can be expected that this technology may make contributions to development of coal gas and shale gas drilling in China, and has definite practical significance. It is worthy for us to pay attention to.
