濮城区块浅井日益减少,随着井深的增加,牙轮钻头的使用磨损也在增大,一口井钻遇研磨性高地层时,难免会造成牙轮提前磨损,造成损坏,缩短使用寿命。通过对抗研磨的PDC钻头的定向使用,有效的节约成本,并且提高机械钻速,缩短钻井周期,具有一定的推广价值。 Pucheng block shallow wells are decreasing, as the depth increases, the use of roller bit wear is also increasing, a well drilling encounter high ground, it will inevitably lead to early wear and tear of the roller cone, resulting in damage and shorten the service life. By confronting the directional use of ground PDC bit, it can effectively save the cost, improve the ROP and shorten the drilling cycle, so it has certain promotion value.
