So in order to improve ROP, the VTK vertical drilling technology of Baker Hughes was introduced. VTK is a kind of closed loop, automatic, and vertical drilling technology, made up of closedloop rotary steering drilling system AUTOTRAK, highperformance X-TREME motor and reliable MWD. It is able to return the well path back to vertical by adopting downhole microprocessors to analyze the measured deviation data and determine the proper force necessary for decreasing the deviation angle to guide the steering rib at the highside to reliably stick out against the upper wellbore.

通过模拟分析比较,揭示出了环件轧制过程中的金属流动规律:轧制时,环件外侧的变形最大,厚向中心部位变形最小,内侧的变形程度介于中间;环件内外环面的压应力分布和变化规律:在垂直于环件轴线的对称面上,压应力分布近似对称状态,而且在对称面上的应力最大,往端面方向开始减小;指出了环件轧制中轧辊与环件摩擦对环件成形的影响:对于环件的宽展变形,摩擦的影响很小,可以忽略;分析了环件进给速度对环件成形的影响并阐述了环件厚向中心部位凹陷产生的原因,提出防止凹陷的措施:在轧制时,尽量使用快的进给速度有利于防止端面凹陷的产生;研究了导向辊位置对环件成形以及轧辊受力的影响:导向辊的位置对环件的宽展变形影响很小,但对轧辊的受力影响较大,当导向辊的中心位置位于毛坯初始中心位置之上时,驱动辊和芯辊的受力相对较小,这是导向辊导向时优先考虑的位置。
