本文介绍了聚晶金刚石复合片(PDC)钻头在墨西哥湾应用的最新研究结果。研究结果评价了PDC钻头在墨西哥湾中新世井段的使用,22个钻头钻进,节约1.4百万美元。由于这项研究结果,建立了PDC钻头的操作指南,每英尺钻井成本显著降低。另外,得出页岩反应性、强度和密度之间的关系。证明有助于选择钻头和确定水力条件,并证明研究结果是正确的。
This article presents the latest research results on the use of polycrystalline diamond compact (PDC) drill bits in the Gulf of Mexico. The study evaluated the use of the PDC bit in the Miocene section of the Gulf of Mexico, drilled 22 bits, saving $ 1.4 million. As a result of this research, guidelines for the operation of PDC bits have been established and drilling costs per foot have been significantly reduced. In addition, the relationship between shale reactivity, strength and density is derived. Proved to help select the drill bit and determine the hydraulic conditions and to prove that the findings are correct.
