摘要: 针对青海油田狮子沟-英中构造带钻遇过程中发生的井漏技术难题,开展了地质分析,施工难点总结,以及钻井液堵漏对策研究。以狮子沟-英中构造带地区SX58井为例,研究发现该地区深部E32 地层低承压裂缝性漏失为井漏的主要因素。针对部E32 地层测井资料及钻井反馈,结合3D打印技术,设计研发了模拟裂缝模型并建立其堵漏实验评价方法。通过室内实验,优化堵漏材料及堵漏浆配方,为青海油田后续优快钻井提供借鉴和指导。

Abstract: Targeting the technical difficulties of well leakage in drilling Shizigou - Yingzhong structural belt of Qinghai Oilfield,geological analysis,operation difficulty summarization and study on plugging measurements are carried out. Taking well SX58 in Shizigou- Yingzhong structural belt as an example,it is found that the low pressure fracture leakage in deep E 3 2 formation is the main factor of well leakage. Based on E 3 2 formation logging data and drilling feedback,combined with 3D printing technology,a simulated fracture model has been designed and developed,and its plugging experiment evaluation method is established. Through laboratory experiments,the plugging material and plugging slurry formula are optimized,which can provide reference and guidance for the follow-up optimal and fast drilling in Qinghai Oilfield.

Key words: Qinghai Oilfield, Shizigou - Yingzhong structural belt, fracture leakage, plugging, 3D printing
