电子压力计井温测试工艺

利用井温曲线可以定性或定量分析油水井的出水层段、吸水层段及套管找漏、管外窜槽等，但目前普遍应用的机械井温仪存在不直观、卡片容量小、停点不清楚、基温调试复杂等问题。近年来应用电子压力计测井温曲线，工艺简单、成功率高，与机械井温仪相比具有快速、经济、准确、不受井深影响等优点。对于井段较厚或隔层发育的井，可代替同位素测吸水剖面。

Downhole Temperature Test Technology with Electronic Pressure Gauges

The use of well temperature log may qualitatively or quantitatively analyse water exit interval,water entering interval, casing leak location, external casing channeling etc., but the mechanical temperature bomb normally used at present has the problems of unintuition,limited chart capacity,indistinct stop points and complicated base temperature adjustment etc. In the past few years,electronic pressure gauges have been introduced to measure temperature log with simple technology and high success ratio,compared to the mechanical temperature bomb,an electronic pressure gauge has the advantages of being quick,economical,accurate,not affected by well depth. To the well with thick intervals or multi - layered system with nonpermeable stringers, it can take the place of isotope to measure water injection profile.
