Controlling Mud Losses in Well Shunbei 52X with High Temperature Chemical Gels

  • 摘要: 顺北52X井是位于塔里木盆地顺托果勒低隆北缘构造的一口勘探井,该井志留系火成岩裂缝发育,地层胶结差、易破碎,承压能力弱,在5600~6200 m井段发生反复的井漏和地层盐水溢流问题,150℃高温地层是阻止化学凝胶堵漏施工的最主要限制因素。为解决上述问题同时拓展化学凝胶的适用温度范围,利用有机凝胶的热塑性、凝胶的复合作用以及改性甲基硅油的缓凝作用,研制出一种新型抗高温化学凝胶。室内实验表明,抗高温化学凝胶的稠化时间能控制在4 h以上,10 h养护抗压强度达3.2 MPa。抗高温化学凝胶在顺北52X井进行的现场试验显示,新凝胶提高了顺北52X井的承压能力,现场试压4.8 MPa,志留系当量密度达到1.40 g/cm3,解决了顺北52X的井漏、出水等地层复杂问题。
