摘要:0152.4mm小井眼钻井技术是提高采收率和综合经济效益的有效途径,大庆徐深气田Xushen9-Ping4井首次在三开水平段开展了小并眼钻井试验,但机械钻建并不理想,制的了深层气并钻并提建和降成本的目标。以①152.4mm小并眼钻井现场试验为例,分析了现场试验中的储层特征、站头进尺、纯站时间和机械钻建,并利用通用机械钻速方程,结合徐深气田储层及小并眼钻井试验情流,得出了小并眼机械钻建的影响因素,并对小井眼钻井过程中存在的同题进行了探讨,为大庆油田深层气井下步开展小并眼钻井试验提供了依据和参考。

Abstract: The O152.4 mm slim hole drilling technique can effectively enhance EOR and overall cconomic performance of oilficld development. Slim hole drilling was tested first in the third drilling section of Well Xushen 9-Ping 4 in the Xushen Gasfield of Daqing Oilfield, but the ROP was lower than expected, failing to fulfill ROP enhancement and cost reduction in drilling deep gas wells. Taking the on site 152.4 mm slim hole drilling as an example, reservoir features, footages drilled per bit, pure drilling time and ROP have been analyzed, and based on the universal ROP equation, features of reservoir formations in the Xushen Gasfield, and experiences in drilling slim hole, factors affecting ROP in slim holes have been figured out, and problems encountered during drilling of such slim holes have ae e oaa se l a s o a e se aad e aee e

大庆油田首次在徐深气田的水平井三开水平段开展了0152.4mm小井眼钻井技术,但由于徐深地区目的层以营城组营一段火山岩储层为主,同时也存在致密砂岩、砂砾、花岗岩及变质岩风化壳等地层,营城组流纹岩地层蕴含石英,研磨性强、可钻性差。隔层发育高角度构造缝、微裂缝和诱导缝,
裂缝发育程度高,封隔性能差,钻井过程中易发生井漏。尽管小井眼钻井试验中应用了抗高温螺杆配合PDC、液动锤配合孕镶PDC钻头、扭力冲击器、液动旋冲工具和旋转导向等提速工具和提速技术,但是三开小井眼的平均机械钻速仍低于邻并的平均水平,严重制约了徐深气田小井眼钻井技术的发展
