Background technology
Oxygen activation well logging instrument is a kind of logger in injection profile field, the a kind of of neutron activation logging, be mainly used to detect flowing of oily WIH, while there is water flow in oil well, by water oxygen is activated and not only can find the existence of current, and observe with long and short two kind spacing the speed that can also try to achieve current.In oil field development production logging injection profile logging field, along with deepening continuously of oil extraction in oil field, the displacement of reservoir oil of application and profile control medium have polymer, ternary to meet agent and CDG gel etc.Because these fluid media (medium) viscosity are high, conventional method of testing can not adapt to the test needs of injection profile completely.
Summary of the invention
Technical problem to be solved in the utility model is for the deficiency existing in background technology, and a kind of novel oxygen activation well logging instrument that improves the effect of injection well, the water injection well displacement of reservoir oil is provided.
The technical solution adopted in the utility model is as follows:
A kind of oxygen activation well logging instrument, by upper helmet, upper seal head, anti-magnetic short section, accelerator for neutron production pipe nipple and probe I, II pipe nipple, tail cap, formed, wherein going up helmet, upper seal head is connected with anti-magnetic short section by magnetic joint, anti-magnetic short section is connected with probe II pipe nipple, accelerator for neutron production pipe nipple, probe I pipe nipple successively by gas-charging connection pipe nipple, and is connected with tail cap by thread bush.
Described anti-magnetic short section comprises magnetic signal urceolus, is arranged at the magnetic urceolus in magnetic signal urceolus, is arranged at magnet steel and coil in magnetic urceolus.
Described gas-charging connection pipe nipple comprises gas-charging connection and is arranged at 5 core inflation plug-assemblies in gas-charging connection.
Described probe pipe nipple comprises probe urceolus, is arranged at probe in probe urceolus and is connected with collection plate and collection plate power supply.
Described accelerator for neutron production pipe nipple comprises accelerator for neutron production urceolus, is arranged at accelerator for neutron production pipe nipple and comprises that the high tension transformer in accelerator for neutron production urceolus is connected with Cockcroft-Walton accelerator, neutron tube, neutron tube helmet and cathode pulse.
The course of work of the present utility model is as follows:
Oxygen atom in the high-energy neutron activated water of accelerator for neutron production transmitting, activated water has the radioactivity that the half-life is 7.13s, utilizes the flowing velocity of detector measurement activated water, determines the flow of borehole fluid according to flow section.
During well logging, according to the situation judgement water (flow) direction of down-hole string and downhole tool, when water (flow) direction is downward, neutron source upper, probe under.When water (flow) direction makes progress, neutron source under, probe is upper.Adopt a shorter pot-life (1-10 second is depending on the speed of current) to select a longer data acquisition phase (being generally 60 seconds) to activate measurement.The speed of current is to determine by the time of probe according to neutron source to distance, the activated water of probe.During well logging, after circuit is connected, after induction coil energising, produce magnetic field, the magnetic flux by induction coil changes, and then produces induced voltage, and this induced voltage is transported to ground by cable, reflects logging signal.
Compared with prior art, the beneficial effect having is the utility model:
Oxygen activation well logging instrument is not subject to an impact for fluid viscosity, is not subject to the impact of tubular column structure, is not subject to lithology, the impact of pore structure and size, can improve targetedly the effect of injection well, the water injection well displacement of reservoir oil.Not only can measure the interior flow of oil pipe and can also measure the flow of separate water injection well oil sets annular space.
