Abstract
The invention discloses a novel horizontal well fluid imager comprising a support arm sensor component, a support arm straightening component and a support arm sensor driving component. The support arm straightening component is used for rotating the support arm sensor component to the position over an instrument so as to ensure that the sensor component is capable of measuring parameters of fluid in a shaft layer by layer; the support arm sensor driving component is used for lifting the support arm sensor component to the needed height to allow the same to scan water holdup and flow of fluid at different height levels on the fluid section continuously. The novel horizontal well fluid imager has the advantages that probes in the same group can perform fixed-point or continuous measurement on different levels of different well depths, and influences on measurement results from probe differences and human factors can be eliminated. A support arm can telescope and elongate freely under stress, so that safety in well logging of the whole instrument can be ensured.
