摘要
塔里木盆地碳酸盐岩储层的储集空间大多以裂缝、孔、洞及其组合为主,极易形成易喷易漏窄泥浆窗口的井眼条件。根据井下的实际情况,通过优选测井工艺、测井项目,制定施工方案、应急措施,以保证测井施工安全。分析了LWD、电缆测井、钻杆传输测井及欠平衡测井的适用条件。提出易喷易漏复杂情况下电缆测井施工必须与声纳液面监测技术、测井电缆悬挂技术配套使用。塔里木油田20余口井的实际应用表明,该测井工艺安全可靠。
Carbonate rock reservoir in Tarim basin riches in fractures, caves and its combination. Logging can not be finished safely in this area because mud density window is so narrow that mud loss circulation and well blowout are easy to occur. To secure the safety of well logging, provided are the measures in operation, such as optimizing logging technology and logging items, establis- hing reasonable operation plan, preparing emergency measures, etc. , in according to the real situation underhole. Analyzed are the using conditions of different logging technologies, such as logging while drilling, cable logging, drill-pipe conveyed logging and underbalance logging. Given that, in this complex condition, cable logging should combine with other logging methods, such as sonar fluid level real-time monitoring technology and logging cable suspension technology. More than 20 logging operations in Tarim basin show that the safety technology provided is reasonable and credible.
