Interlayer or mutation, it is possible to form local anomaly can have greater difference with simulation result, and in experimental formula of actually cementing the well, pole
The small temperature difference can all lead to the performance change of well cementation medium, so the well temperature data that method obtains are not suitable for consolidating for complex area
Well construction；Particularly with certain special well sections, the influence of the anisotropic and short lap on stratum may all bring unknown wind
Danger.
Well logging LWD instruments, which respectively measure, is generally both provided with temperature sensor in pipe nipple, most of temperature surveyed is equal
For underground circulating temperature, this temperature data is mainly used for instrument and judges itself working environment and the correction index caused by temperature influences
Drift, for monitoring its instrument internal heat dispersal situations and correction measured value, so temperature data and the practical well that method measures
Depths well temperature is quite different.
WL wireline logging instruments measurement gained well temperature is similar with LWD well logging modes, and wireline operation is in high angle hole
Or complicated circumstances area risk is especially high, if simple need somewhere well temperature and carry out a wireline logging virtually to entirely applying more
Work process causes all multi-risk Systems and failure waste.
