Abstract
The utility model relates to a device measuring drill holes or wells, in particular to a screw pump well output profile logging instrument. The screw pump well output profile logging instrument comprises a plurality of rigid short section and a plurality of bending short sections, wherein the rigid short sections and the bending short sections are mutually connected at intervals. According to the crew pump well output profile logging instrument, the connecting mode of a traditional instrument is changed, through the design of flexible connection, the length of a single section of the instrument is greatly shortened, and the testing problems of screw pumps and special channel wells are solved. An impedance mode and an over current mode are adopted for the measurement of the water content according to tested objects. While the measurement range of the instrument is enlarged, the measurement accuracy of the water content is accordingly promoted.
Description
Technical field
The utility model relates to a kind of equipment of measuring boring or well.
Background technology
The oil field is reaching more than 3 000 mouthfuls with screw bolt well, but be subjected to the restriction of screw pump pumping unit well down-hole technique and surface drive, the conventional annular space production profile logging instrument of crossing can not be by the well logging passage, and being badly in need of a kind of structure of development can be crooked and satisfy the novel logger of screw bolt well test request.
Summary of the invention
The utility model aims to provide a kind of screw bolt well production profile logging instrument that can improve measuring precision of water content in water.
Screw bolt well production profile logging instrument described in the utility model comprises a plurality of rigidity pipe nipples and a plurality of crooked pipe nipple, wherein the rigidity pipe nipple be connected pipe nipple and connect spaced reciprocally.
Preferably, crooked pipe nipple is section or the curved channel of being flexible coupling.
Perhaps preferably, the rigidity pipe nipple is provided with sensor, current collector and locator.
Screw bolt well production profile logging instrument of the present utility model has changed the connected mode of traditional instrument, by flexibly connecting design, the single-unit length of instrument is shortened greatly, has solved the test problem of screw bolt well and specific channel well.Wherein the measurement of water ratio part adopts impedance type and 2 kinds of modes of overflow-type according to tested object, when enlarging the apparatus measures scope, has correspondingly improved the certainty of measurement of moisture content.
Description of drawings
Fig. 1 is the structural representation of embodiment one.
The specific embodiment
Embodiment one.
Screw bolt well production profile logging instrument comprises successively the A rigidity pipe nipple 1 that links to each other, is flexible coupling 2, B rigidity pipe nipple 1, curved channel 3, C rigidity pipe nipple 1 and be flexible coupling 2.Wherein A rigidity pipe nipple 1 is provided with magnetic localizer and flow contains water sensor, and B rigidity pipe nipple 1 is provided with temperature pick up and pressure sensor, and C rigidity pipe nipple 1 is provided with current collector 4.
Embodiment two.
132-21 one P * * be 1 mouthful of screw bolt well, it is 58 m that well head measures this well production fluid amount
3/ d, moisture content are 90.8%.With embodiment one described screw bolt well production profile logging instrument this well is carried out annular space logging.Well logging as a result table sees Table 1, and closing layer output is 63.6 m
3/ d.The output of 3 layer positions is respectively 7.5,16.4 m
3/ d and 39.7 m
3/ d.Payzone under 1 146.9 m is the main fluid producing layer of this well, and output accounts for 62.4% of full well production.The mixed phase value that records at 1 135 m places and full water number are respectively 559.2 Hz and 511.2 Hz, and calculating moisture content through Logging Software is 89.8%.As seen embodiment one described each parameter of screw bolt well production profile logging instrument is working properly, and flow and moisture content have higher certainty of measurement, and logging instrument is fine to high water-cut well.
Table 1.
Embodiment three.
NB * * well is l mouth low water cut well, it is 22.7 m that well head measures this well production fluid amount
3/ a, moisture content are 4.1%.With embodiment one described screw bolt well production profile logging instrument well logging.Well logging as a result table sees Table 2, and total output is 23.4 m
3/ a.As seen embodiment one described each parameter of screw bolt well production profile logging instrument is working properly, and flow and moisture content have higher certainty of measurement, and logging instrument is fine to low water cut well.
