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

China University of Geosciences(Beijing), Beijing 100083

摘要

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。

Abstract: The well Shunbei 52X is an exploratory well located in the north margin of the Shuntuoguole low uplift, Tarim Basin. This well penetrated a section of the easy-to-break Silurian igneous rocks with plenty of fractures, poor cementation and low-pressure bearing capacity. Repeated mud losses and well kicks happened during drilling from 5,600 m to 6,200 m. High formation temperature of 150℃ was the major reason prohibiting the use of chemical gel to stop mud losses. To deal with mud losses encountered and extend the use of chemical gel, a new high temperature chemical gel was developed, making use of the thermoplasticity of organic gel, the compound action of gel and the retarding effect of modified methyl silicone oil. Laboratory experimental results showed that the thickening time of the high temperature chemical gel can be maintained to more than 4 h, and the compressive strength of the chemical gel after aging for 10 hours was 3.2 MPa. The high temperature chemical gel was used on the well Shunbei 52X to control mud losses; the pressure bearing capacity of the formations at which mud losses have happened in the past was increased to 4.8 MPa as tested, and the equivalent circulation density of the Silurian system was raised to 1.40 g/cm³, successfully resolving the mud losses and well kick problems encountered in drilling the well Shunbei 52X.
