FREMGANGSMAATE OG APPARAT FOR AA FREMBRINGE EN GRAFISK REGISTRERING AV OMKRETSEN AV ET BOREHULL

摘要

The invention relates to the well logs for the study of the cement in a bore and in particular for the production of a recording, which represents the quality of the connection of the cement all around the tubing. / p & & p & the process for obtaining such a recording comprises, in a first step, the production of measurement signals relating to the zones of different casings distributed at the periphery of the tubing. The measurement signals are converted into signals quantified having a number of possible values. It is then recorded on a film - support of the parallel strips formed each by a succession of zones, the grades are determined by the values of the signals quantified. / p & & p & it is thus obtained a recording, which represents the periphery of the probing in the form of a surface whose hue developed in each zone indicates the quality of bonding.
