Access opening be connected between two access opening holes and using inclined hole between central passage, as stratum water filling flow direction channel；Its
In, first hole is as flow rate test channel, and second hole is as flow-regulating passage, in the hole two in the flow rate test channel
End installation flow rate test probe (2), the flow rate test probe (2) are all-metal sealing ultrasonic transducer, flow rate test probe
(2) it tightens to be connected on intelligent watering device ontology (1) by screw thread and passes through sealing ring (3) and bore seal, described in water flow process
Flow rate test channel is popped one's head in by the flow rate test enters the flow-regulating passage after (2) carry out flow rate test and by setting
It sets and injects stratum after the runoff investigation unit (4) of flow-regulating passage is adjusted.
The present invention realizes following beneficial technical effect:
By adopting the above-described technical solution, a kind of permanent setting type flow testing device of the patent of invention is with method with following
Feature:
1, real-time and long term monitoring downhole flow, can realize the auto-control to flow with runoff investigation unit matching, entirely
Envelope is adjusted and tested to automatic survey, and realizes automation and intelligentification.
2, flow rate test channel aperture is big, is not easy to be blocked by sandstone dirt etc., and flow direction is more reasonable, flow rate test probe
It is not easy sand dirt etc., and reversely can carry out probe cleaning dirt by well-flushing, guarantees probe test performance.
3, flow rate test precision is high, and test effect is more preferable, and all-metal sealing ultrasonic transducer voltage endurance capability is high, and sealing can
It leans on, long service life, underground long-time service can be met.
