core re orientation

To orient core precisely and take the oriented core quickly is the key to design a core oriented device.

快速、準確地對孔內巖心定向取出高質量的定向巖心 ,是研制定向取心器的關鍵。

The paper introduced the principle of core-storage directional core drilling,the key techniques,instrument constitution,technical parameters and the site application.

采用巖心定向取心技術不僅可以迅速而方便地確定地下礦層和結構面的產狀,而且還可以判斷礦層的走向,了解地層傾向,預測鉆孔彎曲的趨勢。
