Description
The present invention is an a kind of rock complex resistance laboratory measurement system.Belong to the rock physics field.Can under high-temperature and high-pressure conditions, measure by the complex resistance (impedance) to rock sample.
Usually, in the laboratory, be to measure the rock electrical parameter at normal temperatures and pressures.But, tested rock sample is often taken from underground high temperature and high pressure environment, the difference of this environment can make measured value and the rock under the normal temperature and pressure that bigger difference is arranged between the actual value under the original high-temperature and high-pressure conditions, thereby influences using and analyzing of rock measured value.
In order to remedy this gap, the objective of the invention is to design under a kind of simulated formation high-temperature and high-pressure conditions measuring system, thereby make that the laboratory measurement value of the rock actual value original with it is more approaching the rock sample complex resistance.
The present invention is a rock sample complex resistance measuring system under a kind of high-temperature and high-pressure conditions.By hand oil pump 1, transtat 2, temperature controller 3, high temperature high pressure device 4, electric impedance analyzer 5, printer 6, microcomputer 7, plotting apparatus 8 is formed.High temperature high pressure device 4 adopts No. 45 steel to make housing 410, left side lid 411, right lid 49 and plug 46 through quench.Housing 410 inwalls place in the cavity 413 of housing 410 around two left-hand thread formula rubber sleeves 44 that 43, one of the stainless-steel tubes of putting the interior dress resistance wire that is used to heat are used for pressure transmission and sealing, and thermal resistance sensing probe 48 stretches in the cavity 413, the temperature in the detection cavity.Tested rock sample 41 is a column, places in the rubber sleeve 44, and each tie-in amount electrode 42 of the two ends of rock sample 41, potential electrode 42 links to each other with electric impedance analyzer 5 by electrode wires 47.In order to insulate, between electrode 42 and plug 46, put into column plastics 412.Stainless-steel tube 45 links to each other with hand oil pump 1, by steel pipe 45 to cavity 412 oilings with the pressurization.Microcomputer 7 links with electric impedance analyzer 5 by GPIB plate 9 and gpib bus 10.
The present invention can be 50MPa at top pressure, maximum temperature is in 150 ℃ the scope, on the measurement frequency range of a broad, the rock sample of any lithology is carried out the sweep measurement of complex resistance, can satisfy factories and miness, school and R﹠D institution under the situation of present drilling well well depth, carry out the measurement and the research of the rock complex resistance of simulate formation high temperature and high pressure environment, thereby the geophysical parameters of the best is provided for petroleum prospecting, exploitation.
Fig. 1 is a structured flowchart of the present invention.
Fig. 2 is a high temperature high pressure device structural representation of the present invention.
Below in conjunction with description of drawings a kind of preferred plan of the present invention.
The rock sample complex resistance measuring system of simulated formation high-temperature and high-pressure conditions, by hand oil pump 1, transtat 2, temperature controller 3, high temperature high pressure device 4, electric impedance analyzer 5, printer 6, microcomputer 7, plotting apparatus 8 is formed.Microcomputer 7 can use COMPAQ386 or IBM compatible.Microcomputer 7 is by GPIB plate 9 and gpib bus 10 and electric impedance analyzer 5 UNICOMs.Electric impedance analyzer 5 is selected model HP4194A for use.The electrode wires 47 of high temperature high pressure device 4 links with the measuring junction of electric impedance analyzer 5.The complex resistance R+jx of tested rock sample 41 measures in system by automatic frequency sweep.The size of rock sample 41 can adopt diameter 25mm, and length is 38mm, and rubber sleeve 44 adopts fluororubber, and its internal diameter is 25mm, so that closely cooperate with rock sample 41.Hand oil pump 1 can adopt SYB-2 type hand oil pump, and it links to each other with high temperature high pressure device 4 by 6mm stainless-steel tube 45, its effect be with hand by pressure oil pump, oil pressure is gone into high temperature high pressure device 4, the pressure with increase cavity 413 causes a hyperbaric environment.Temperature controller 3 can adopt SWT102 type temperature controller, and it links to each other with the input end of transtat 2, and the output terminal of transtat 2 is connected with resistance fiber tube 43 in the high temperature high pressure device 4.For avoiding electrical interference, the resistance fiber tube adopts antispin shape (S shape) around the home.Microcomputer 7 can export measurement and result to printer 6 and plotting apparatus 8.
Before the measurement, with resistance wire steel pipe 43, oil fuel tube 45 and thermal resistance sensing probe 48 are fixed in the cavity 413 as shown in Figure 2, and twist with sealing nut the junction, again rubber sleeve 44 is put into cavity 413, and left side lid 411, right lid 49 are screwed on housing 410.During measurement, tested rock sample 41 is put into rubber sleeve 44, again with electrode 42, column plastics 412 and plug were put in rock sample 41 both sides in 46 minutes, and tightened.The measuring junction of electrode wires 47 with electric impedance analyzer 5 joined.
Shake hand oil pump 1, after installing oiling in 4, treating that oil is full of cavity 413, oiling again, the oil pressure in the cavity 413 just raise gradually, and this moment, oil pressure loaded on the rock sample 41 by rubber sleeve 44, formed the hyperbaric environment to rock sample 41.Simultaneously, because the left-hand thread at instinct oil extruding rubber sleeve 44 two ends makes oil pressure high more, the left-hand thread edge is good more with contacting of housing, and sealing property is good more.Open temperature controller 3, and temperature is set at a certain specific upper limit value, then have electric current to pass through on the resistance wire in the steel pipe 43, thereby the heating such as oil, rubber sleeve 44 and rock sample 41 in the cavity 413 are given in heating.When the temperature in the cavity 413 surpassed the temperature value of setting, temperature controller 3 outputs were interrupted, and no current passes through on the resistance wire, stops heating, and the temperature of cavity 413 just is stabilized on the temperature value of setting, causes a stable hot environment.At this moment, just can carry out the measurement of rock sample complex resistance R+jx under uniform temperature and the pressure with electric impedance analyzer 5.Measuring process is by microcomputer 7 controls, and data storage is also undertaken by microcomputer 7 with processing.
