horizontal borehole pressure recorder 水平钻孔压力记录器
horizontal projection of borehole 井身水平投影图
horizontal long borehole 水平长钻孔
The pressure loss in horizontal borehole may have certain influences on production performance of fractured horizontal wells.
水平井筒内的压力损失对压裂水平井的生产动态有一定的影响；
Real-time evaluating the stratum by the using LWD (Logging While Drilling) curve could ensure horizontal borehole extend effectively in the reservoir bed and improve rate of drilling.
利用LWD曲线实时评价地层，可以确保水平井井眼在储层中的有效延伸，提高钻遇率。
The horizontal lateral displacement of reinforced concrete or rail anti-slide piles is measured by setting up borehole incline-tube in pile.
通过在大截面钢筋混凝土和钢轨抗滑桩身埋设钻孔测斜管，监测得二类抗滑桩的水平侧向位移。
