| 中文摘要:为适应鄂尔多斯塔巴庙区块勘探开发需要，利用区域测井资料进行钻头选型，并结合现场实践优化钻头类型和钻井参数，提高钻井效率。通过新型PDC钻头推广应用,单口井所需钻头数量减少3~4只，减少起下钻3回次以上，缩短钻井周期3~5天。 |

| Abstract:To meet the need of exploration in Tabamiao Area of Erdos , the bit type was selected by making use of the data from well observation and optimizing bit type and drilling parameters by site practice. In the application of new type of PDC bits, the number of bits used for a single well was reduced 3~4, well-completing period was shortened 3~5 days. |
