II-A type instrument.
2., instrument string by reaching casing space after partially stifled, lead to positive electricity to current collecting umbrella Electromagnetic Flow annular space instrument A and open casing
Current collecting umbrella, electromagnetic flow transducer therein start to measure casing flow；Casing data on flows three times is acquired, respectively 1. with step
In the Liquid output implemented compare, carry out validation instrument flowmeter stability, if positive negative error is no more than 5%, flowmeter is stablized
Property it is qualified；If the flow error measured is more than 5%, instrument string replacement current collecting umbrella Electromagnetic Flow annular space instrument A is above mentioned, then again
It goes into the well and measures.
3., instrument is moved up and down in casing space, acquire casing data on flows twice at an arbitrary position, respectively with step
1. the Liquid output implemented in compares, validation instrument weight by flow renaturation, similarly, if positive negative error is no more than 5%, flow
It is qualified to count weight renaturation, if the flow error measured is more than 5%, above mentions instrument string replacement current collecting umbrella Electromagnetic Flow annular space instrument A,
It goes into the well again again, repeats step 2., 3..
4., total No. five casing datas on flows for 2. 3. measuring step with step be averaged, obtain casing flow Q1,
Then current collecting umbrella Electromagnetic Flow annular space instrument A is led into negative electricity and closes casing current collecting umbrella, instrument string is played into well head, takes out casing afflux
Umbrella Electromagnetic Flow annular space instrument A removes weighted lever, disconnects end.
5., by the upper end oil-pipe type current collecting umbrella Electromagnetic Flow annular space instrument B connecting cable head, and in oil-pipe type current collecting umbrella electromagnetic current
The amount lower end annular space instrument B mounts weighted lever, and weighted lever lower end connects underground guiding device C, and instrument string is normally gone into the well, wherein oil-pipe type
II-Type B of HK-DC-80- that current collecting umbrella Electromagnetic Flow annular space instrument B is produced using Daqing oil field measuring technology service branch company
Instrument.
6., instrument string is by the way that after casing space, the righting elastic slice 6 on the guiding device C of underground is flicked, and makes instrument string centre bit
It sets and is biased to oil pipe mouth, continue to transfer instrument, the guider of the underground bottom guiding device C cone is prevented raming and 5 can slide into oil pipe mouth,
The smooth tripping in oil pipe of entire instrument can be made to reach purpose depth.
7., lead to positive electricity to oil-pipe type current collecting umbrella Electromagnetic Flow annular space instrument B and open casing current collecting umbrella, electromagnetic sensor starts to survey
Dipping tube flow acquires oil pipe data on flows three times, takes the average value of casing data on flows three times, obtain casing flow Q2；Oil
Cast current collecting umbrella Electromagnetic Flow annular space instrument B leads to negative electricity and closes oil pipe current collecting umbrella.
8., instrument string plays to well head, take out oil-pipe type current collecting umbrella Electromagnetic Flow annular space instrument B, remove weighted lever and underground
Guiding device C disconnects end.
9., by comparison Q1With Q2It obtains with the presence or absence of leakage, if Q1=Q2, then prove that higher level's packer sealing is good；
If Q1>Q2, then prove that upper packer leakproofness is poor, there are leakage phenomenas.
The ternary composite driving layering output well casing column tests underground guiding device used in encapsulation method, the underground guiding device
It is used when measuring oil pipe flow, including weighting connector 3,3 upper end of weighting connector and oil-pipe type current collecting umbrella electromagnetic current
The weighted lever for measuring the bottom annular space instrument B is connected, and 3 lower end of weighting connector is connected through a screw thread guide bar 4, and the two junction
It is fixed by caging bolt 7, it prevents from rotating between each other.The 4 middle section diameter of guide bar is greater than both ends diameter, guide bar
The outside at 4 both ends is cased with spring nut 2 respectively, and opposite side is connected separately with spring standing screw on two spring nuts 2
1, and righting elastic slice 6 is connected between two spring standing screws 1.4 bottom of guide bar is connected with guider and prevents raming
5, cone is in anti-5 lower ends of raming of guider, and the lower end of circular cone is round end.
Before instrument string is gone into the well, which is connected to instrument string bottom, when instrument string passes through ring set space, arrival
When casing, guider elastic slice 6 is flicked, and maximum can flick 6cm, and instrument string center is made to be biased to oil pipe mouth, continues to transfer instrument,
When guiding device touches oil pipe, anti-5 lower ends of raming of conical guider can slide into oil pipe mouth, and entire instrument can be made smooth
Tripping in oil pipe.
Example is missed in embodiment one, plugged zone position:
The teams and groups that log well carry out the evaluation of plugged zone position to B2-363-E67 separate-zone producer, the tubing string schematic diagram of the well as shown in figure 3,
Implementing the same day well Liquid output first is 33.5m3/d, according to construction requirement, Field Force's tripping in casing current collecting umbrella Electromagnetic Flow
Annular space instrument A, successively measure three times depth be 910 meters at casing Liquid output, measured value be respectively 33.88m3/d, 33.5m3/d,
34.32m3/d has good stability so as to the electromagnetic flowmeter of validation instrument.Instrument is above mentioned to successively surveying twice at 908 meters
Casing Liquid output is obtained, measured value is 31.95m3/d, 31.88m3/d respectively, and the repeatability of validation instrument is also good, takes five surveys
Amount casing flow average value is 33.11m3/d, so obtaining casing flow Q1=33.11m³/d.Similarly by oil-pipe type current collecting umbrella electricity
Guiding device C in underground is hung under magnetic flow annular space instrument B, packer is crossed after instrument string is imported oil pipe, respectively in 933 meters, 933.2
Rice measures oil pipe Liquid output 20.33m3/d, 20.06m3/d, 20.48m3/d at 933.5 meters, measures oil pipe flow three times and makes even
Mean value is 20.29m3/d, so oil pipe flow Q2=20.29m³/d。Q1>Q2, it was therefore concluded that well plugged zone position leakage, wastage
12.82m³/d。
Embodiment two, plugged zone position do not miss example:
Teams and groups log well to the progress plugged zone position evaluation of B2-363-E65 producing well, the tubing string schematic diagram of the well is as shown in figure 4, implement
The same day well Liquid output is 31.87m3/d, according to construction requirement, using same logging method respectively 913 meters in casing,
Casing flow 32.45m3/d, 31.78m3/d, 30.91m3/d are measured at 913.7 meters, 910.3 meters, are averaged 31.71m3/d,
So casing flow Q1=31.71m³/d.Similarly guiding device C in underground will be hung under oil-pipe type current collecting umbrella Electromagnetic Flow annular space instrument B,
By instrument string import oil pipe after cross packer, respectively 930 meters in oil pipe, 930 meters, 930.5 meters measure oil pipe flow 32.21m
3/d, 32.27m3/d, 32.98m3/d, taking the average value measured three times is 32.49m3/d, so oil pipe flow Q2=32.49m³/
D, because of Q1≈Q2, it was therefore concluded that the well plugged zone position good seal has no leakage.
