电子压力计保护装置的研制和试验

Developingt and Testing Protective Device for Electronic Pressure Gauge

高温高压井的射孔-测试联作中,易损坏昂贵的井下电子压力计。针对井下实际情况,研制了一种新的井下电子压力计的保护装置,其具有良好减震性能,并能降低射孔瞬间突然增压对压力计探头的冲击作用。该装置经过现场试验,效果良好。

The downhole electronic pressure gauge is vulnerable and costly in the perforation--DST combination operation in the HTHP well. For this reason, the paper presents an innovative protective device for the downhole electronic pressure gauge with effective shock absorbing property, which can reduce the shock action on the pressure gauge probe resulted from the sudden pressurization at the moment of perforating. The device has taken good performance through field test.
