Abstract
The utility model discloses an imager for monitoring a well diameter, and particularly relates to a multi-arm well diameter imager that can work normally when a well wall deforms. The multi-arm well diameter imager comprises a cable sealing head, an upper centering device, a control piece, an imaging arm sensor, a lower centering device and a counterweight joint, wherein the cable sealing head is connected with one end of the upper centering device; the other end of the upper centering device is connected with the control piece through telescopic arms; the control piece is connected with the imaging arm sensor; the imaging arm sensor is connected with one end of the lower centering device; the other end of the lower centering device is connected with the counterweight joint through telescopic arms; and 1-40 monitoring arms are arranged around the imaging arm sensor. The multi-arm well diameter imager can measure parameters such as the internal diameter of a petroleum casing, a casing coupling, a well temperature and natural gamma (optional) in real time accurately, and is faster in data processing, lower in power consumption, better in test passing property, and wider in application scope, and the external diameter of the imager is reduced greatly.
Description
Technical field
The utility model is a kind of imager of monitoring hole diameter, particularly a kind of Multi-finger Imaging Tool for still working under borehole wall deformation.
Background technology
Existing hole diameter imager is in the situation that inclined shaft or at borehole wall fouling, wax deposition, the serious petroleum casing pipe that easily tangles of deformation comparison can't work instrument, and software can not be made stereogram, cannot analyse the distortion particular location.
Summary of the invention
The purpose of this utility model is in order to overcome existing hole diameter imager in the situation that the defective of borehole wall distortion cisco unity malfunction, invent a kind of can accurately measure in real time petroleum casing pipe internal diameter, casing coupling, well temperature, GR (apolegamy) thus etc. parameter depict sleeve pipe distortion, undergauge, hole enlargement, break, the Multi-finger Imaging Tool of the damaged condition such as bad break.
The purpose of this utility model realizes as follows: described Multi-finger Imaging Tool, comprise cable seal head, upper centralizer, control member, imaging arm sensor, lower centralizer and counterweight joint, cable seal head is connected to an end of centralizer, the other end of upper centralizer is connected with control member by telescopic arm, control member is connected with the imaging arm sensor, the imaging arm sensor is connected to an end of lower centralizer, the other end of lower centralizer is connected with counterweight joint by telescopic arm, and the surrounding of imaging arm sensor is provided with a plurality of monitoring arms.
Described monitoring arm is 1-40.
Good effect of the present utility model is as follows: the utility model can be measured the parameters such as the internal diameter, casing coupling, well temperature, GR (apolegamy) of petroleum casing pipe in real time accurately, thereby depict sleeve pipe distortion, undergauge, hole enlargement, break, the damaged condition such as bad break, variation in conjunction with magnetic orientation, by the gentle DTEM of gradient well, find out the particular location of the run-down or perforation of sleeve pipe; The processing of the utility model data is faster, power consumption is lower, and the instrument external diameter greatly reduces, and its test trafficability characteristic is good, and its range of application is more extensive.

The specific embodiment
As shown in Figure 1, described Multi-finger Imaging Tool, comprise cable seal head 1, upper centralizer 2, control member 3, imaging arm sensor 4, lower centralizer 5 and counterweight joint 6, cable seal head 1 is connected to an end of centralizer 2, the other end of upper centralizer 2 is connected with control member 3 by telescopic arm 7, control member 3 is connected with imaging arm sensor 4, imaging arm sensor 4 is connected to an end of lower centralizer 5, the other end of lower centralizer 5 is connected with counterweight joint 6 by telescopic arm 8, and the surrounding of imaging arm sensor 4 is provided with a plurality of monitoring arms 9.
Described monitoring arm 9 is 1-40.
The utility model belongs to precision equipment, before well logging, should first drifting, and can effectively guarantee the success rate of logging well and the accuracy of measured value, can prevent that also instrument from being blocked or damaging in well.After drifting, tighten up the monitoring arm and begin to go into the well, for righting effect is preferably arranged, the open-angle adjustment of centralizer system larger when entering well head, closed centralizer with hand, and instrument is passed through smoothly, is sure not to clash, and when instrument arrives the section of being hampered, delay lower instrument; Prevent that instrument from inserting in sand too dark, in order to avoid stuck, obstruction measuring system.Forbid work apparatus in sand.As this phenomenon occurs, and instrument is proposed Shamian Island, repeatedly open, receive gage beam, make the apparatus measures arm be in normal operating conditions, then carry out further work.
