The original twice down well processes are changed into the new process that all logging information is completely taken by once down well by the oxygen activation up-down water flow combined logging instrument. The utility model has the advantages of logging time saving, logging cost reduction and system error reduction.
Description
(1) technical field:
The utility model belongs to the oxygen activation logging instrument, particularly relates to oxygen activation current combination logging tool up and down.
(2) background technology: the oil field that has mainly is to carry out the oxygen activation instrument development at the fluid entry profile of polymer injection well, because polymer viscosity is bigger, and the requirement of incompatibility polymer injection section plane test of existing input profile conventional logging instrument.For example: when using the turbo flow meter well logging, because of injected fluid viscosity increases, cause measuring error once big, even turbine does not rotate and can't measure; Tracer method is also because polymer viscosity is big, injection rate IR is low and the perforating depth on stratum is big, the stratum unequal factor affecting of imbibition hole also can not get ideal results.
(3) utility model content:
Technical problem to be solved in the utility model is at the problem that exists in the background technology, and a kind of a kind of oxygen activation that is not subjected to in-hole fluid viscosity influence current combination logging tool up and down is provided.
The invention for solving the technical problem can reach by following technical solution: in the housing that three core slip rings, high-voltage power supply transducer, Cockcroft-Walton accelerator I, insulating cylinder, neutron tube, seven core slip rings, nearly detector, power module, far detector, data acquisition circuit, gamma ray detectors, four-core slip ring are housed downwards successively from the top, be equipped with neutron tube under the four-core slip ring successively, have the Cockcroft-Walton accelerator II and the high-voltage power supply transducer of insulating cylinder, and the high-voltage power supply transducer places on the magnetic box cupling of housing bottom.
Above scheme is to adopt " two bill receipts " pattern, has both adopted the unitized construction of one group of probe, two cover neutron generators.Neutron generator is under the control of control circuit, the transponder pulse neutron, oxygen element in the interior liquid of pit shaft is activated equably, activation oxygen is along with water flow to detector, and the feature gamma rays of release is detected device and receives, compose by Measuring Time, calculate water from being activated to the time that device receives that is detected, the time that flows to detector according to neutron source to the distance and the activated water of detector is determined the flow velocity of water, both V=L/T.Measuring method is: adopt short pot-life (1-10s), select long data acquisition phase (being generally 60s) to activate measurement.The speed of current is according to the distance of neutron source to detector, and activated water was determined by the time of detector, is a kind of time measurement of known distance, and repeatedly duplicate measurements is to improve measuring accuracy.
The utility model is compared with background technology has following beneficial effect: this instrument makes twice original downhole technique, the new technology that becoming once goes into the well has got whole well-log informations, can save the well logging time, reduce logging cost, improve logging efficiency, reduce systematic error, solve the test problem of oil field input profile better.
