The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Shown in Fig. 1 and Fig. 2, should comprise release 8 by the spike correlative flow logging instrument based on binary channels release and single detection system,
On release 8, be followed successively by from left to right liquid tracer release channel A1 and the liquid tracer release channel B2 of mutual interlock, two liquid tracer release channel A1 are all connected with liquid tracer release drive system 3 circuit with channel B 2, in the course of work, by drive system, controlled, thus atomizing of liquids tracer; Interconnective gamma detection system is housed in the Instrument shell 7 being connected with release 8, comprise gamma detection crystal 4, photomultiplier 5 and gamma control acquiring and transmission system 6, liquid tracer release drive system 3 is controlled acquiring and transmission system 6 with gamma and all by logging cable, is connected with ground installation.
In the correlative flow logging instrument course of work, after instrument is gone into the well, by ground installation, control liquid tracer release drive system 3, drive liquid tracer release channel A 1 and the liquid tracer release channel B 2 while releasing liquid isotopic tracer of release 8, tracer enters in well and forms suspension with borehole fluid, with borehole fluid, flow, when the suspension that the tracer discharging when two passages and borehole fluid form is flowed through gamma detection crystal 4, gamma detection crystal 4 gathers gamma ray, gamma ray is converted to the signal of telecommunication after entering photomultiplier 5, gamma is controlled acquiring and transmission system 6 above-said current signal is transferred to ground installation instrument.When the suspension that the tracer discharging when two passages (A, B) and borehole fluid form is flowed through gamma detection crystal 4, to there are two peak values in log response, two interchannel distances of liquid release are known, time between two peak values can try to achieve by log response curve, can calculate the flow velocity of borehole fluid thus, and then the flow of calculating borehole fluid, as shown in Figure 2.For example the tracer with certain polymerism is discharged in oil pipe, form suspension with borehole fluid, tracer flows with borehole fluid, when it flows through eccentric injection mandrel, part tracer will flow in oil jacket space by water nozzle, along with on current direction or flow downward, when the suspension that tracer and borehole fluid form is flowed through crystal detection there is peak value in measurement parameter (gamma counting rate), by calculating, can try to achieve the flow velocity of medium in well and then ask for flow.
