概述

概述

从组合完整性测试/泄漏测试(fit/lot)中获取压力概况,并在AccuFIT™ real-time flow-off pressure data servicefrom Baker Hughes. By enabling pressure data to be transmitted uphole immediately after the test, the AccuFIT service improves the quality and accuracy of measurements compared to surface-based FIT/LOT methods.

通过实时压力数据提高测量精度

拟合和批量是评估敞口截面可以容忍的最大压力的宝贵方法。但是,由于具有胶结单元和钻机泵压力表的数据准确性的挑战,常规的,基于表面的测试受到限制。壳体孔效应(包括泥浆可压缩性,被困在钻孔流体中的气体以及壳体膨胀)也限制了所获得的压力数据的准确性。

Accufit服务通过提供实时的下井数据来解决这些挑战。该服务为整个批次/拟合间隔提供了初始的60分压力时间曲线。该轮廓已足够详细,可以立即可视化整个流动事件,并确定达到泄漏压力和击穿压力。它还估计崩溃压力后的斜率。

ACCUFIT服务是当前最小/最大流动环压力的扩展ontrak™andAzitrak™tools. But while these tools required pulling out of hole (POOH) to download the flow-off annular pressure data from the OnTrak/AziTrak memory, the AccuFIT service commences initial transmission downhole, immediately after circulation resumes. No time-consuming rig downlink is required.

If higher resolution data is required for a particular time interval of interest, the AccuFIT service can “zoom in” by sending an additional downlink for 60 data points over that shorter time interval. A downlink to cancel LOT/FIT transmission can be sent downhole when the service is no longer required or enable it when needed.
