HOUSTON -- Schlumberger has introduced the ACTive Q CT real-time downhole flow measurement service, which delivers real-time injection diagnostics and treatment evaluation in just one run in a well.
休斯顿-斯伦贝谢介绍了ACTive Q CT实时井下流动测量服务，能够仅在一趟钻进行实时注入诊断和作业评价。
“Fluid injection monitoring and placement often requires customers to reach conclusions through trial and error or time-consuming logging operations,” said Amerino Gatti, president, Well Services, Schlumberger. “With the ability to measure pressure, temperature and fluid velocity in real time during interventions, the ACTive Q service improves our customers’ understanding of downhole wellbore and reservoir behaviors while intervention is ongoing. This helps facilitate customers’ decision making and improve the effectiveness of treatment placement.”
斯伦贝谢井服务部门的经理AmerinoGatti说：“流体注入监测和定位通常需要客户通过反复试验或耗时的日志记录得出结论。随着在干预过程中有能力来实时测量压力、温度和流体速度，ACTive Q服务提高了我们的客户对干预过程中井下井筒和储层流动行为的了解。这可以帮助客户更容易做出决策，提高作业位置的有效性。”
With the ACTive Q service, which couples fiber-optic telemetry and calorimetric flow measurements, customers and Schlumberger can evaluate the flow rate contribution to each interval, review the data in real time and adjust the pumping schedule as needed for diversion and subsequent stimulation stages.
基于ACTive Q服务，并结合光纤遥测和热量流量测量，客户和斯伦贝谢可以根据转向和后续增产作业的需要，评价每一层的流量贡献，实时检查数据，调整泵的时间表。
The ACTive Q service has provided real-time flow measurement information for several operators in the Middle East, North Africa and Central America.
ACTive Q服务已经为中东、北非和中美洲的不同作业者提供了实时流动测量信息。
For example, when a water injector well in Sabriya field exhibited falling injection rates and an increase in injection wellhead pressure, Kuwait Oil Company (KOC) wanted to effectively target sections that needed stimulation or diversion while avoiding additional logging runs. Using the ACTive Q service, two primary thief zones at each extremity of the well were identified. The middle section that was not taking any fluid was targeted for acid placement. As a result, the wellhead injection pressure decreased from 1,000 psi to 0 psi with a constant injection rate of 8 bbl/min. In addition, the ability to combine real-time flow monitoring, injection profiling and acid stimulation in a single run significantly reduced costs by eliminating three days of operations.
例如，当Sabriya油田的注水井出现注入率下降和井口注入压力增加的现象，科威特石油公司(KOC)想要有效的确定需要增产或转移的层位，同时避免额外的下入作业。使用ACTive Q服务，在每个发生事故的井发现了两个主要的漏失层。中间层位没有流入任何流体，被作为进行酸化的目标层。结果，在恒定注入排量8 bbl/min的条件下，井口注入压力从1000 psi降至0 psi。此外，该服务使得实施流动监测、注入分析和酸化压裂能够在一趟钻完成，节省了三天的作业时间，大大降低了作业成本。
