Key Drilling Technologies for Complex Ultra-Deep Wells in the Tarim Keshen 9 Gas Field

  • 摘要:

    塔里木克深9气田超深井具有井眼超深、高温和高压的典型特征,钻井过程中存在钻井周期长、盐膏层高压盐水与薄弱漏层同存、盐上高陡地层防斜打快难,吉迪克组地层和致密砂岩储层机械钻速低等问题。为解决这些问题,在盐上地层应用了垂直钻井工具,并优选了高效PDC钻头,在盐膏层采用了高密度油基钻井液、控压放水技术和盐膏层安全钻井技术,在致密砂岩储层应用了360旋转齿钻头、涡轮钻具+孕镶钻头提速技术,形成了克深9气田复杂超深井钻井关键技术。该技术在克深9气田2口井进行了现场应用,平均钻井周期缩短12.0%,故障处理时效降低4.1百分点,平均机械钻速提高13.0%。研究结果表明,塔里木克深9气田复杂超深井钻井关键技术能够满足该气田超深气藏高效勘探开发的需求,对国内外类似超深井高效钻井具有一定的借鉴。
