| Abstract:The special petroleum drillable float collar and float shoe are applied in the casing running in large diameter borehole of coalmine and well cementing. With this new technology, the conventional cement base setting or floating plug by welding steel plate to the case+one-way grouting valve is replaced and the procedure of casing running and well cementing are simplified. By these means, the engineering cost is saved and the well quality is guaranteed. The paper introduces the technology application and the effect in recharging hole of Wutongzhuang mine. |
