Specific embodiment
Below with reference to the embodiments and with reference to the accompanying drawing the technical solutions of the present invention will be further described.
Embodiment:
The resistivity measurement electrode array configurations of LWD resistivity log tool of the present invention design, can be in underground With the measurement of drilling row formation resistivity.Its resistivity measurement electrode array configurations design support tool carries out rotary drilling in underground Into when resistivity imaging measurement and resistivity imaging measures both of which when slipping drilling.It mainly passes through different emission measurements The design of electrode system, so that ac current signal is pushed into stratum by electrode system, and the exchange that measurement flows through stratum and returns simultaneously Electric current, to reflect that electrode system periphery is measured the resistivity information on stratum, electrode system is rotated and slided with drilling tool can be by drilling well The true resistance rate information for being drilled stratum in journey is recorded, and ultimately forms the resistivity image of tested wellbore formation.
Formation resistivity basic principle of measurement:
The resistivity logging feature different according to rock resistivities different in stratum, to distinguish rock category on drilling well bubble face Property, rock resistivity can reflect the physical quantity of rock conductive capability power under the conditions of extra electric field.For material homogeneous The cross section of its resistance and object is inversely proportional for object, directly proportional to the length of object, can obtain formula
Wherein R is the object resistance rate coefficient, is not only had with the material properties of object in relation to the geometry with object Relationship.Therefore, the resistivity of object is
It can obtain from the equations above, the resistivity unit of rock is ohm meter, numerically one square metre long for section The resistance value of the rock of one meter of degree.The value is higher to illustrate that electric conductivity is poorer, otherwise explanation conducts electricity very well.
When drilling tool rotary drilling and when slipping drilling in the wellbore, due to conducting electricity very well for drilling fluid, especially high resistant Between stratum and drilling tool, when the drilling fluid having had conductivity, by the electric current of the electrode outflow on drilling tool almost in the drilling well of wellbore It is flowed in low-resistance country rock on liquid and the borehole wall, is less able to flow into tested purpose stratum, the resistivity measured in this way is also hardly Variation.Therefore the method for using strengthening electric current penetration capacity enables alternating current to penetrate what the entrance of low-resistance country rock was tested Purpose measures in stratum.
Therefore LWD resistivity log tool drill collar surface used by tool machined the circular drill collar of a protrusion Periphery, and make array electrode on the circumferential surface, can be measured in LWD resistivity log tool when underground is slided The resistivity of 360 degree of rocks of wellbore, to realize the resistivity imaging method on stratum when slipping drilling.As shown in Figure 1, outstanding Periphery is in order to enable resistivity measurement electrod-array is in the wellbore closer to tested stratum.
Electrode measurement array is divided into two rows of and interlaced as shown in Figure 1, it can cover the tested stratum in wellbore. Each electrode structure in every row's electrode is identical, as shown in Fig. 2, its shape is long and narrow cuboid, cuboid is long and narrow by 4 Nested rectangular conductive ring and a rectangular conductive electrode are constituted layer by layer.Wherein rectangular conductive electrode is located in 4 layers of rectangular conductive ring The heart is filled into steel ceramic insulating material and insulate between rectangular conductive electrode and rectangular conductive ring.
Wherein metal electrode A0 is the main electrode in electrode system, and metal electrode ring M1 and metal electrode ring M2 are electrode systems Monitoring electrode retaining collar in system, metal electrode ring A are the focusing electrode in electrode system, and metal electrode ring B is returning for electrode system Galvanic electricity pole.It is all equal in the various pieces current potential of endless metal since electrode retaining collar M1, M2, A and B are annular conductive metal. When electrode work, main electrode A0 and electrode retaining collar A are applied the identical high tension voltage of polarity, and applying high voltage is in order in quilt It is generated in geodetic layer and gos deep into stratum electricity potential gradient.Under the action of polarity identical two high voltages, main electrode A0 and electrode Ring A will generate the identical electric current IA0 and IA of corresponding polarity, in circuit system by adjusting the size of IA, to realize metal electricity Polar ring M2 is identical with the current potential of metal electrode ring M1.Since voltage will not be generated between metal electrode ring M2 and metal electrode ring M1 Difference, ensuring that between metal electrode ring M2 and metal electrode ring M1 does not have electric current to flow through yet, thus in metal electrode ring M1 and The annular region of a bucking current will be formed between metal electrode ring M2, and is in the metal electrode A0 inside the annular region The electric current IA0 of generation can only flow into tested stratum along this passage area, without the periphery expansion to this annular region. Achieve the purpose that the electric current IA0 for forcing metal electrode A0 to generate deeply is tested stratum perpendicular to tool v drill collar surface.Its Current distribution is as shown in Figure 3.
The region that principal current IA0 is generated is as shown in figure 3 above, and the electric current generated is with a thickness of metal electrode ring M2 and metal electricity Midpoint between polar ring M1 will generate the region principal current IA0 of an annular closure in this position.This is the view on tested stratum Resistivity Ra is as shown by the following formula.
UM1 is the current potential of M1 metal electrode ring, and K is the coefficient of electrode system, when the circuit system of tool v is started to work, When principal current IA0 is constant, the current potential on the current potential of M1 metal electrode ring is according to the view on formula above and tested stratum electricity There are proportionate relationships for resistance rate.I.e. when tool in wellbore along the borehole wall slipping drilling when, be tested stratum apparent resistivity variation It is reflected in the potential change of metal electrode ring M1, tool passes through the available quilt of potential change on measurement metal electrode ring M The apparent resistivity information of geodetic layer.
And when tool is when wellbore slide inside is crept into, each electrode on electrod-array on tool can carry out simultaneously The apparent resistivity measurement on tested stratum, by all electrode measurements to apparent resistivity summarize icon be made, it will be able to reflect When tool is along borehole wall slipping drilling, the apparent resistivity image on 360 degree of tested stratum in wellbore.
Metal electrode ring B can be used as the return electrode of bucking electrode A1, the electricity that adjustable main electrode A0 is loaded Flow the depth of IA0 invaded formation.
When the measuring circuit for measuring principal current IA0 disconnects the connection with metal electrode ring B by switch, metal electrode ring When B is not return electrode, the return electrode of bucking electrode A1 is measured in the distal end of whole branch measuring tool, bucking electrode A1 and whole branch The potential surface range that the distal end of tool is formed is big, therefore the bucking current that bucking electrode A1 is issued can force principal current IA0 to invade Enter the deep position in stratum, i.e. principal current IA0 can dissipate just now farther awayly in the Distance tool.As shown in Figure 3.
When the measuring circuit for measuring principal current IA0 passes through the connection of switch conduction metal electrode ring B, metal electrode ring B As return electrode, the return electrode electric current of bucking electrode A1, as shown in figure 4, just being sent out after tested stratum slight depth will be entered It scatters, and flows into the measuring circuit of principal current IA0 by metal ring electrode B, is i.e. between bucking electrode A1 and metal electrode ring B Formation screen potential face range is small, therefore forced principal current IA0 gos deep into the depth as shallow on stratum, therefore principal current IA0 is apart from work Have closer place to dissipate.It is arranged by the switching of this return electrode, the resistance of two kinds of measurement ranges of the depth may be implemented Rate imaging.On the basis of the resistivity imaging of two kinds of ranges of the depth, load high tension voltage value on bucking electrode A1 is adjusted, it can It is further finely tuned with bottoming to formation resistivity.
Embodiment 2
When tool is when underground carries out rotary drilling, embodiment 2 can be completed when drilling tool rotates to stratum tested in wellbore Resistivity imaging measurement.
Herein it is emphasized that the structure of embodiment 1 and embodiment 2 can be used alone, also combinable use, that is, exist Two nested structures are installed on the same drill collar.Its resistivity measurement electrode array configurations design support tool carries out rotary drilling in underground Into when resistivity imaging measurement and resistivity imaging measures both of which when slipping drilling.
By formation apparent resistivity imaging formula
It can be seen that formation apparent resistivity is in addition to the electric current that flows through with voltage, the metal electrode A0 on metal electrode ring M1 IA0 has (IA0 in formula 4 is exactly the electric current IC that measuring electrode flows out in Fig. 6) outside the Pass.It is also related to k-factor.This k-factor It is electrode coefficient relevant with electrode design.
Electrode COEFFICIENT K can be acquired by following formula
A0M1L, A1M1L, A2M1L, A1A2L, B1B2L, B1M1L, B2M1L in formula are each point as shown in Fig. 5 Between linear distance.Such as A0M1L is in Fig. 3 or Fig. 4 shown from metal electrode A0 to the equivalent distances of metal electrode ring M1. Fig. 2,3,4 are the structures of a measurement metal electrode in array of measure electrodes shown in Fig. 5, and the η 1 in formula is metal electricity The ratio of the electric current I0 of electric current IS and main electrode the A0 outflow of polar ring A1 outflow, referred to as bucking current ratio, i.e. following formula
Resistivity imaging measurement of the drilling tool when underground is slided and measured to 360 degree of tested stratum may be implemented in the above structure.
The groove of multiple installation coils is processed on drill collar, and portion's processing installation balance monitoring coil recess in the structure, The groove two sides machined electrode array, electrod-array is as shown in figure 5, to be looped around on 360 degree of directions of drill collar.That processes is wider Groove is to place launch monitor coil M0-M10.The relatively narrow groove of processing is to place transmitting coil T1-T10.
The working principle of the structure be as shown in Figure 6 in for T1, M1, T2, M2, I1 and I2 respectively represent mono- in T1 and T2 Ring electrode electric current detected under the intensity excitation of position;Similarly, Mij indicates the ring-like monitoring coil Mi under the excitation of Tj unit strength Electric current detected.The excitation of upper and lower ring-like transmitting coil differs 180 ° in phase, therefore, when upper ring-like transmitting coil drives When streaming current flows downward along drilling tool, under ring-like transmitting coil driving current flowed up along drilling tool, the axial direction at ring electrode Current polarity is opposite, cancels out each other, i.e., the voltage measured on transmitting balance monitoring coil is zero.Upper and lower ring-like emission lines Circle compels to draw current out array of measure electrodes simultaneously, thus enhances the electric current of electrode measurement electrod-array.The symbol of each electric current Number by following agreement: when electric current radially flows out, I1 and I2 are positive, and when electric current flows downward, M01 and M21 are positive, and work as electric current M02 and M12 is positive when flowing upward.
Array of measure electrodes electric current Ic is defined by the formula:
Equation (7) is that symmetrically, when subscript exchanges 1 and 2, equation is remained unchanged in form.Due to reciprocity, M12 =M21.
The weighted sum of equation (7) expression ring electrode electric current I1 (T1 excitation) and I2 (T2 excitation).Per the ring electricity individually motivated Electrode current can all distinguish scale for view formation resistivity, but all there are above-mentioned serious response aberration problems.However, logical It crosses and I1 is zoomed in and out and is added with I2 as equation (7), ring electrode electric current can be compensated, to obtain excellent sound Answer characteristic.Because the ring electrode current polarity generated by T1 and T2 is identical, is overlapped mutually, so that array of measure electrodes electric current Error will not be than individually motivating the error of ring electrode electric current high.As shown in fig. 6, emitting when adjusting electric current caused by T1 and T2 When voltage produced by the position balance monitoring coil M0 is zero, it is ensured that the electric current issued from array of measure electrodes can go deep into quilt Geodetic layer, measures resistivity value.When tool starts rotation in the inswept wellbore of electrode of each sector of array of measure electrodes Stratum can measure the resistivity value of wellbore formation.When drilling tool rotary drilling, the electrode of the structure is inswept borehole wall stratum can be with Tested wellbore formation resistivity is imaged.Select T1 T2, T3 T4, T5 T6, T7 T8, T9 T10 coil inductance L phase Go deep into the different measurement electric current of stratum degree to can produce Deng, middle different coil, to measure different depth rock stratum in wellbore Resistivity information.Wherein T1 T2 coil is most deep to the measurement electric current depth for going deep into stratum of generation, and the depth that T9 T10 is generated The measurement electric current depth for entering stratum is most shallow.By T1 the alternating current that is applied on T2 coil be actuated to amplitude equal phase angle Differ 180 degree, thus T1 the electric current I1 and I2 that is induced in drill collar axial direction of T2 coil in drill collar middle section measuring electrode battle array Column meet, and at this moment the equal but contrary electric current of two amplitudes can cancel out each other on drill collar axial direction, and electric from measurement Pole array flows into stratum perpendicular to drill collar, forms electric current IC as shown in FIG. 6, electric current IC will be flowed back by stratum T1 T2 The negative potential 2 of coil.Therefore can in circuit control timesharing select different coils to (such as the first moment T1 T2 coil it is same When be applied the electric current of amplitude equal direction difference 180 degree, and measure the size of IC, by stratum flow back into T1 T2 line The path longest of negative potential is enclosed, the depth of stratum of measurement is also most deep.T1 T2 coil to T9 T10 coil clock synchronization time-sharing work , when T9 T10 coil to work when, return flow path is most short, and the stratum of measurement is also most shallow.) electric to generate the measurement of different depth Stream, to measure the resistivity information of rock in wellbore.
Specific embodiment described herein is only an example for the spirit of the invention.The neck of technology belonging to the present invention The technical staff in domain can make various modifications or additions to the described embodiments or replace by a similar method In generation, however, it does not deviate from the spirit of the invention or beyond the scope of the appended claims.
