Specific embodiment
Below in conjunction with attached drawing, the present invention is described in detail
Embodiment 1:
Fig. 1 is that the downhole hardware connection in High water cut horizontal well outlet part Bit Parity element labeled test method of the invention is shown
It is intended to, Fig. 2 is the isotope release device structural schematic diagram in the present invention.In Fig. 1, Fig. 2, binding test example, to this hair
Bright test process is illustrated.But those skilled in the art are it should also be understood that the present invention is not limited to listed specific
Embodiment should all be included in protection scope of the present invention as long as meeting spirit of the invention.
Test process of the invention includes: three test device assembling, tubing transmission tripping in, production test processes.
Test device assembling: by the water-solubility carrier A5 containing isotope A, the water-solubility carrier B6 containing isotope B, contain
There is the water-solubility carrier C7 of isotope C to be separately mounted in isotope release device.
Tubing transmission tripping in: by sequence of going into the well, horizontal well ball seat 8, isotope release device 4, envelope are sequentially connected with oil pipe 9
Every device 3, set pressure valve 2, oil extraction pump 1, using 9 transmission mode G.I.H of oil pipe, as shown in Figure 1.
Production test: base sealed packer 3, the examination of oil extraction pump 1 are taken out 6-12 hours, exclude to stop after hydrops and Carryover effect in well
Pump.Casing, which is suppressed, opens isotope release device 4, and oil extraction pump 1 starts to go into operation, and it is laggard that well head recovered water carries out gamma spectrum analysis
It stands.According to the isotopic species and feature content seized, the diagnosis at water outlet position is carried out in conjunction with horizontal well geologic data.
Isotope release device in the present invention includes connector 10, loudspeaker collection port 11, water inlet flows to slot 12, carrier is pacified
Tankage 13, carrier release chamber 14, water outlet flow to slot 15, and connection relationship is: 13 both ends of carrier mounting groove pass through screw thread
It is fixedly connected with connector 10, is successively fixedly installed ring-type outside the annular barrel that connector 10 and carrier mounting groove 13 are constituted
The water inlet communicated flows to slot 12, carrier discharges chamber 14, water outlet flows to slot 15, and the entrance that the water inlet flows to slot 12 is provided with
Loudspeaker collection port 11；The connector 10, carrier mounting groove 13, water inlet flow to slot 12, carrier release chamber 14, water outlet flow to slot
15 be concentric setting.Water flow is collected by loudspeaker collection port, is flowed to slot through water inlet and is washed away carrier to release chamber, and dissolution
The solution of isotope is through being discharged the horizontal segment for flowing to slot and being discharged on the outside of oil pipe.
In the present embodiment, there are three the identical isotope release devices of structure for setting altogether, and isotope release device 4 is it
In one.Water-solubility carrier A5 containing isotope A, the water containing isotope B are installed respectively in three isotope release devices
Solubleness carrier B6, the water-solubility carrier C7 containing isotope C, isotope A, B, C difference in above three water-solubility carrier
For Ru, Sr, Ta.
In conjunction with the example that the single production section of High water cut horizontal well is discharged, the test philosophy of this method is illustrated.
High water cut horizontal well goes out water problems, is oil reservoir under the collective effect of natural factor and artifact, causes to drive
Some of grease body in horizontal segment, which produces section, to be occurred breaking through.Strong interference is produced to produce section to other, causes horizontal well
There is the violent downslide even zero of High water cut and crude output, i.e. the part production a large amount of recovered waters of section of horizontal segment in production, and its
It is few without output or output that he produces section.
By means of the present invention, isotope release device is laid in multiple downstreams for producing section, then this High water cut is horizontal
The flow characteristics of well, can by recovered water isotopic species and feature content captured and analyzed.
For example, at toe water outlet, heel and middle part without output situation.Along the heel of horizontal segment, middle part and toe three productions
The downstream of section lays three isotope release devices 4.Because heel and middle part produce section without output, in heel and middle part dissolution release
Isotope A, B will can not be carried to ground because of not flowing.γ detection will will detect that isotope C and its feature
Content, and isotope A, B will test less than thus can compare geologic data according to testing result can examine water outlet position
It is disconnected.
At middle part, water outlet, heel and toe are without output situation.The isotope A of heel dissolution release will because of not flowing,
And ground can not be carried to.And in flow process of the output water at middle part along " the outer annular space-shaft bottom-oil pipe-ground of oil pipe ",
Other than carrying the isotope B of middle part dissolution release, the isotope C of toe dissolution release will be also carried.It is same due to carrier
The position element flowing that rate of release is proportional to flow velocity and output water is from middle part to toe is same flow velocity.γ on ground is examined
Survey will will detect that isotope B, C and approximately uniform feature content, and isotope A will test less than thus can be according to detection
As a result control geologic data diagnoses water outlet position.
In heel water outlet, middle part and toe are without output situation.The output water of heel is along " outer annular space-shaft bottom-the oil of oil pipe
The flow process of pipe-ground " will also carry middle part, toe dissolution is released other than carrying the isotope A of heel dissolution release
Isotope B, the C put.Due to carrier release isotope speed to flow velocity proportional and output water from " heel-middle part -- toe
Portion " is same flow velocity, and γ detection will will detect that isotope A, B, C and approximately uniform feature content, thus can be according to detection
As a result control geologic data diagnoses water outlet position.
In conjunction with the example that multiple production sections of High water cut horizontal well are discharged, the test philosophy of this method is described further.
The case where middle part and toe water outlet, heel are without output.The output water of middle part and toe is along " the outer annular space-of oil pipe
The flow process in shaft bottom-oil pipe-ground ", the adduction at middle part and toe water yield, will cause toe flow velocity big within the unit time
In middle part flow velocity, the γ detection on ground will will detect that the feature content difference of isotope B, C and the two, and isotope C
Feature content can be greater than the feature content of isotope B.Thus geologic data can be compareed according to testing result to carry out water outlet position
Diagnosis.
In downhole hardware connection in High water cut horizontal well outlet part Bit Parity element labeled test method of the invention, underground
The quantity of isotope release device can be determined according to the quantity of down-hole horizontal section oil reservoir, and placed in water-solubility carrier
Different isotopes.
High water cut horizontal well in the present invention is the oil well that water yield reaches 85%.
