When the present invention works, as shown in Figure 2, when described FDT modular dual probe formation tester is gone into the well, probe piston SRV1, SRV2, SRV3, SRV4 is in corresponding cavity bottom, first probe 2 and the second probe 11 shrink, probe valve PV1, PV2, strainer valve FV1, FV2 closes, equalizing valve EV1, EV2, isolating valve ISO1, ISO2 opens, the inner first probe fluid line 39 of tester of the present invention, second probe fluid line 40 and formation fluid always flow pipe and are communicated with and are communicated with the outside mud of instrument, instrument flow test macro and pit shaft peripheral sludge barrel pressure balance each other.
When instrument is behind arrival order stratum, when needing to open probe test, electromagnetic valve SOL1 in hydraulic system, SOL2 energising is opened, hydraulic oil enters probe piston SRV1 respectively, SRV2, SRV3, SRV4 backup chamber, promotion piston is outwards mobile presses to the borehole wall respectively by the first probe 2 and the second probe 11, probe packer 53 is tightly attached on the mud cake of the borehole wall, probe tube 50 and the mud in pit shaft are separated, probe valve PV1 simultaneously, PV2 piston is released and opens, probe tube 50 is made to be close to object stratum through the mud cake in pit shaft, equalizing valve EV1, EV2 closes, the probe fluid line of instrument internal and outside mud is completely isolated opens, after in strainer valve piston 51 chamber, oil pressure reaches setting value, safety valve RV2, RV3 is communicated with, strainer valve FV1, FV2 realizes Time Delay Opening, now formation fluid communicates completely with the stream tube inlet of probe fluid line, formation fluid just by filter probe device 48 in sonde configuration, can filter aperture on valve rod 49, strainer valve piston 51 intermediate conduit, formation fluid carrier pipe 52 and fluid hinged pipe 56, finally flow into the first probe fluid line 39, and in the second probe fluid line 40, setup test.
When formation testing pressure, first electromagnetic valve SOL5, SOL6 energising, close isolating valve ISO1, ISO2 makes probe fluid line and the total fluid line of formation fluid separate, test fluid flow system lock, only with stratum UNICOM, carries out test and prepares, when carrying out pretest, electromagnetic valve SOL1 and SOL2 is still energized, electromagnetic valve SOL3 and SOL7, ISO8 is energized, hydraulic oil is by SOL3 and SOL7, SOL8 enters pretest PRV1, PRV2 piston upper chamber, piston moves downward stop motion after full scale, a negative pressure is increased in fluid line closed system, formation fluid slowly enters pretest chamber PRV1 under negative pressure effect, PRV2 fluid cavity, until be full of pretest chamber, negative pressure disappears, strain gauge SG1, SG2 and quartz crystal pressure meter CQG1, CQG2 records pressure change when formation fluid enters each pretest chamber respectively, obtain strata pressure recovery curve, again in conjunction with corresponding fluid volume, conveniently can obtain each stratum different directions permeability.Under the condition ignoring seepage, the volume pumping oil is exactly pretest volume; Be provided with resistivity sensor RES1, RES2 in the probe fluid line that sample flows through and Real-Time Monitoring is carried out to the formation fluid entered in instrument, timely differentiation fluid type (oil, gas, water), thus determine whether to be drawn into desirable formation fluid, now, if will sample, electromagnetic valve SOL5, SOL6 power-off, opens isolating valve ISO1, ISO2, probe fluid test pipeline is communicated with formation fluid main pipe line, and formation fluid enters fluid main line successively and samples.
When needs reclaim probe, each electromagnetic valve power-off, System recover original state, probe backup piston SRV1, SRV2, SRV3, SRV4 return cavity bottom, first probe 2 and the second probe 11 shrink, probe valve PV1, PV2, strainer valve FV1, FV2 close, equalizing valve EV1, EV2, isolating valve ISO1, ISO2 open, first probe fluid line 39, second probe fluid line 40 always flows pipe with formation fluid and is communicated with, and be communicated with the extraneous mud of instrument, instrument internal formation fluid test system and the outside mud pressure of instrument are balanced each other.
