| 中文摘要:为提高庆深气田水平井钻井速度，缩短钻井周期，降低钻井投资，在徐深1-平3井三开进行了旋冲钻井试验。通过分析钻具组合强度，结合不同尺寸液动旋冲工具特点，制定提速技术方案，优选钻井参数并进行现场试验。经验证，液动钻井在徐家围子深层直井段提速效果明显。试验从分析新钻具组合强度是否满足钻进需求，防止应力集中造成钻具疲劳破坏入手。根据大庆ZJ50D型钻机一般泵压≯25 MPa的实际情况，利用液动旋冲工具泵压-排量回推公式，优化钻井参数。基于参数优选结果制定针对性施工措施，确保φ279 mm型液动旋冲工具现场试验成功。 |

| Abstract:In order to improve the drilling speed of the horizontal well to reduce drilling investment in Qingshen gas field, a rotary percussion drilling test was carried out in the 3rd opening interval of Xushen1-Ping3. By the analysis on the strength of the BHA and according to the characteristics of hydraulic rotary tools with different dimensions, the acceleration technology scheme was formulated, the drilling parameters were optimized and the field tests were made. It was proved that there was obvious improvement in deep vertical section by hydraulic drilling. First of all, from the analysis on testing whether the new BHA strength meets the drilling requirements to prevent fatigue failure of drill caused by stress concentration. The drilling parameters were optimized by the pump pressure-displacement back-stepping formula of hydraulic rotary tools under the condition of the fact that the pump pressure of ZJ50D rig is generally no more than 25MPa in Daqing. Based on the parameter optimization result, the specific construction measures were formulated to ensure the successful field test of φ279mm hydraulic rotary tool. |
