Embodiment Construction

[0013] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0014] As shown in the figure, this new horizontal well fluid imager mainly includes a support arm sensor assembly, a support arm swing assembly and a support arm sensor pushing assembly. The support arm sensor assembly is used to measure the water holdup and flow rate, and then obtain wellbore fluid imaging results by processing the measured data; the arm swing assembly is used to turn the arm sensor assembly directly above the instrument, so as to ensure that the sensor assembly can measure the parameters of the fluid in the wellbore layer by layer The arm sensor push assembly is used to raise the arm sensor assembly to the required height, which can continuously scan the water holdup rate and flow rate of the fluid at different heights in the fluid section; the instrument is controlled separately by dual motors in the horizontal state The posture is correc...

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.

Description

technical field [0001] The invention relates to an instrument for logging the production profile of a horizontal well in an oil field, and is a novel horizontal well fluid imager for measuring the water holdup and flow rate of the wellbore fluid of the horizontal well in layers and sections. Background technique [0002] Along with the development of horizontal well technology, horizontal well production logging has also become an important topic in front of oil people. At present, in addition to measuring conventional production logging parameters including temperature, pressure, magnetic positioning, natural gamma ray, density, water cut, and flow rate, the production logging of horizontal wells is more important to measure the fluid composition in the wellbore of the horizontal well, that is, the wellbore The distribution of the fluid in the wellbore, as well as the flow rate and flow state of the fluid at different positions in the wellbore. Therefore, in addition to so...
