This paper mainly introduces the application of naturally-communicated well pair and directional drilling communicated well pair in Jiangxi Salt Mine Co.
文章主要介绍了自然连通井组,定向钻井连通井组在江西盐矿有限责任公司的应用实际,分析了各自在多层薄层盐矿床开采中的特点,提出定向钻井连通井组为最佳开采工艺选择。
During directional drilling,tool face often deviated from the desired direction due to the friction caused by the relative motion(rolling and sliding) between the bit and the formation.
定向钻井中,钻头与地层之间的相对运动(滚动和滑动)所产生的反扭矩导致工具面不断偏离井眼设计轨道,为解决该问题,国外石油公司研制出了一种全新的无反扭矩钻井装置,并进行了初步的现场试验。
The common drilling assembly was introduced used in directional well drilling in the"straight-by-steady-down-stability"phase.
介绍了定向井钻井过程中"直-增-稳-降-稳"阶段常用的钻具组合,结合现场所用钻具,分析了各个阶段所用钻具的特点,并优选了钻具组合。
