- Radial horizontal well is the most complicated one in horizontal well series,it has a major horizontal section and one or several branch sections. 辐向水平井是水平井系列中的高难度井，它除了有一段水平井段外，还有另外一条或多条分支井段。
- The movement of top coal and top roof is discussed with the data observed from the caving mining of deeply inclined thick coal seam with horizontal section in Zhaogezhuang colliery of Kailuan Group. 就开滦集团赵各庄矿在急倾斜厚煤层采用水平分段开采过程中的现场观测，探讨顶煤和顶底板运移。
- Because of long chain couple helix composition of XC, XC can drag reduction, make drilling fluid keep disturbed flow condition in horizontal section, and stop cutting bed formation. XC的长链状双螺旋结构使其具有减阻作用,使钻井液在水平段始终处于紊流状态,阻止了水平段岩屑床的形成;
- ERD wells are widely adopted due to its great economic benefits and its applicability fur special purposes, while the drag along the horizontal section has limited the promotion of ERD wells. 摘要大位移井技术因其具有巨大经济效益并能够满足特殊作业的目的而得以迅速推广应用，但水平井段摩阻扭矩又成为了制约大位移井推广应用的关键因素。
- The vertical line meets the horizontal one here. 垂直线与水平线在此相交。
- Orientation optimization of the horizontal section; 优化水平段方位;
- dummy horizontal section assumption 拟平截面假定
- In order to carry out technical study of coring drilling in large horizontal sections of horizontal wells, field experiments are conducted in the horizontal section of the Xing 6-1-Ping 35 well. 摘要为开展水平井水平段大段取心钻井技术研究，在杏6-1-平35井的水平段进行了现场实验。
