Through similar material simulation the horizontal and vertical stress of arch rock stratum in pressure equilibrium is observed.
通过相似材料模拟，对压力平衡拱处岩层的水平应力和竖直应力的观测。
During the producing process of a horizontal well, fluid flow in well bore and stratum filtering flow have the restraining and effecting actions.
在水平井生产过程中，井筒内管流与地层渗流互相制约、互相影响、互为边界条件，从而构成了一个完整的水动力学体系。
The Ordovician is the hydrocarbon source rock and also is one of the main series of stratum in exploration, which is characterized by wide distribution and greatly vertical-horizontal variation.
奥陶系是烃源岩，也是主要勘探层系之一，具有分布广，纵、横向变化大的特点。
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。
Is drills the deep well, the extra-deep well, the horizontal well, the slant hole, the directional well, the windowing well and the low seepage stratum well essential ideal equipment.
是打深井、超深井、水平井、斜井、定向井、开窗井及低渗透地层井不可缺少的理想设备。
