Guarantee the accuracy of flow rate test by the multiparameter synergism such as magnetic orientation, temperature, pressure, hole diameter in journey.
The purpose of the present invention can be achieved by the following technical measures：Well stratified flow rate method for testing, this well stratified flow
Weight testing method adopts well stratified flow rate test instrument, and the method includes：Step 1, well stratified flow rate test instrument is gone into the well,
During going into the well, monitoring water injection string box cupling and downhole tool position are it is ensured that well stratified flow rate test instrument is parked in the middle part of interlayer；
Well stratified flow rate test instrument is placed centrally in pit shaft by step 2 in target zone；Step 3, in measurement flow and oil pipe
Footpath situation of change, by internal diameter-flow scale plate, revises the impact to test data for the tubing string fouling after COMPREHENSIVE CALCULATING.
The purpose of the present invention also can be achieved by the following technical measures：
The electric centralizer of well stratified flow rate test instrument receives arm, passes through the magnetic of well stratified flow rate test instrument during going into the well
Positioning cutting back monitoring water injection string box cupling and downhole tool position, realize the accurate of well stratified flow rate test instrument depth of setting
Positioning.
In step 1, well stratified flow rate test instrument also opens up the temperature, pressure of well stratified flow rate test instrument during going into the well
Cutting back enrolls temperature profile, the water suction situation slightly sentencing each layer with this and the leakage situation of tubing string of injection well.
In step 2, in target zone, the electric centralizer of well stratified flow rate test instrument is stretched one's arms, and well stratified flow rate
It is placed in the middle in pit shaft that mechanical centralizer collective effect below the effusion meter of examination instrument realizes well stratified flow rate test instrument.
In step 3, the effusion meter of well stratified flow rate test instrument, micro- hole diameter of well stratified flow rate test instrument simultaneously are opened
Measurement pipe aperture situation of change, by internal diameter-flow scale plate, revises tubing string fouling to test data after COMPREHENSIVE CALCULATING
Impact.
The present invention proposes a kind of well stratified flow rate method for testing, by lead-in cable reading technology, logical in test process
Cross the multiparameter synergism such as magnetic orientation, temperature, pressure, hole diameter to guarantee the accuracy of flow rate test；Instrument was gone into the well
Water injection string box cupling and downhole tool position can be monitored by observing magnetic locating signal in journey, realize instrument depth of setting
It is accurately positioned；Instrument can enroll temperature, the pressure traverse of injection well with opening temperature pressure parameter during going into the well, with this
Slightly sentence the water suction situation of each layer and the leakage situation of tubing string；The internal diameter change of monitoring water injection string while admission zonal flow rate,
Plate is associated come the test result of modified flow rate by internal diameter-flow.The method introduces the mentality of designing of electric centralizer,
While solving lower curved section instrument problem placed in the middle, the situation of change of measurement water injection string internal diameter, significantly improve flow rate test
Accuracy, the method can achieve the flow rate test under the complex situations such as little interlayer, hole deviation, tubing string fouling.
