Cuttings and core from the drill-holes have intersected conglomerate bands. 钻粉和岩心已穿过了砾岩夹层。
This allows the drilling fluid to suspend cuttings when drilling stops. 这一特性使钻井液在钻探停止时仍能使钻屑悬浮于其中。
A simple laboratory testing method is established,and by means of this method mechanical bond strength is tested between drilling cutting and oilwell cement rock. 在实验室内,模拟水泥环与地层胶结全过程,分析了泥饼以及采用不同配方的水泥浆,对各种钻屑与油井水泥胶结强度的影响。
