Abstract
The present invention belongs to a displaying and evaluating instrument for the oil gas of mud. Mud can be directly analyzed and tested when the content of underground oil gas is analyzed and measured. The instrument is provided with a lower gas inlet pipe (1), a pressure stabilizing valve (2), a three-way (3), a pressure gauge (4), a flow stabilizing valve (5), a support frame (6), a sample inlet rod (7), a pyrolysis furnace (8), a crucible (9), a gas outlet hole (10), a detector (11), a gas inlet pipe (12), a hydrogen inlet pipe (13), an upper gas inlet pipe (14) and a pump (15). The instrument has the advantages of high testing precision, high analyzing speed, safety, convenience, no easy loss of samples, etc. and can be extensively used for the analysis and the test of mud in various oil fields.
Description
Technical field the invention belongs to a kind of mud oil-gas shows evaluation apparatus device.
Background technology is present, when take a sample at analysis to measure underground oil and gas content in the oil field, takes solid sample or gaseous sample to detect more.If the liquid towards sample detects, can only take sample changeover to be become gaseous state or solid-stately detect again.The liquid towards sample lacks special-purpose detecting instrument.
Summary of the invention the present invention can be when analyzing underground oil and gas content, and directly liquid towards sample (being generally mud) is analyzed.
Its principle of work is as follows:
Earlier mud sample is put into crucible 9, when sample feeding rod 7 pushes electric furnace 8, have the two-way carrier gas to enter electric furnace 8 from two-way up and down respectively, the carrier gas of setting out on a journey enters electric furnace 8 by last draft tube 14; The carrier gas of following road, enters in the chamber of electric furnace 8 through the venthole of opening in sample feeding rod 7 upper ends 10 through pressure maintaining valve 2, threeway 3, flow stabilizing valve 5 by lower inlet duct 1.Venthole 10 is symmetrical arranged a plurality of around sample feeding rod 7, in the chamber of electric furnace 8, form one horizontal " air curtain ", make the carrier gas that enters in electric furnace 8 chambeies from last draft tube 14 smooth " sweeping along " mud sample vaporized gas enter detecting device 11, guarantee normally carrying out of detection.Under low-temperature condition, detecting device 11 is measured the gaseous hydrocarbon value S of mud sample
0Then, the temperature of beginning electric furnace 8 raises, and at this moment, pump 15 is started working, extract the steam in the electric furnace 8, and discharge out of the furnace, when the hydrogen flame of detecting device 11 can be lighted, pump 15 work stopped, electric furnace 8 furnace temperature continue to raise and keep a constant temperature, continuation is heated mud sample, and at this moment, detecting device 11 records the liquid hydrocarbon value S of mud sample
1After, the temperature linearity of electric furnace 8 raises, and when rising to eventually temperature, detecting device 11 is measured the cracking hydrocarbon value S of mud sample
2According to the S that records
0, S
1, S
2, detecting device 11 promptly can be judged the oil-containing tolerance of sample.Tensimeter 4 can be indicated the pressure of carrier gas.Incoming air conduit 12 and advance hydrogen pipe 13 and be connected on simultaneously on the detecting device 11, input air and hydrogen use during for detecting device 11 operate as normal when detecting device 11 work.The exhaust tube of pump 15 and last draft tube 14 are connected on the top of electric furnace 8.Sample feeding rod 7 can be slided along support 6 easy on and off.
