Key Techniques for Deep Well Drilling Optimization in the Block Matambo,Colombia

  • 摘要: 哥伦比亚Matambo区块油藏埋深约5 000.00 m,具有地层倾角大、多套压力系统、地应力高、多断层破碎带、多层大段泥岩、巨厚砾石层及异常高压地层等特点,6口深井在钻井过程中频繁发生井塌、阻卡和井漏等井下故障,导致钻井速度慢、钻井周期长。为提高该区块油气勘探开发效益,在充分分析该区块地质情况和总结已完钻井施工经验的基础上,从井身结构优化、井眼轨道设计与轨迹控制、多参数随钻监测与分析、固井工艺优化及钻井液体系优选等方面进行了技术攻关,形成了适合该区块的深井钻井关键技术,并在G10ST5井进行了现场试验。G105ST5井顺利钻至设计井深,井身质量和固井质量满足设计要求,与该区块其他6口深井相比,钻井周期缩短了20.7 d,平均机械钻速由3.00 m/h提高到7.00 m/h,井下故障损失时间在钻井周期中的占比由原来的15%~30%降至7%,钻井综合成本降低近45%。现场试验结果表明,Matambo区块深井钻井关键技术能够满足深井钻井提速提效的要求,也为其他类似区块复杂深井的优快钻井提供了技术借鉴。
