The specific embodiment

As shown in Figure 1, 2, 3, it is that housing becomes drawer-type structure and main frame, ups power and tool box to be installed in simultaneously in the integrating cabinet that total hydrocarbon intelligent logging instrument, drilling geology parameter acquisition unit, infrared total hydrocarbon gas analysis unit, electricity take off from motion tracking control module, main frame, ups power and tool box with standard industry control cabinet; Its circuit is connected to main frame and adopts RS232 serial ports and drilling geology parameter acquisition unit, infrared total hydrocarbon gas analysis unit respectively, and engine degasser links to each other from the motion tracking control module is two-way.

The various reflection drilling conditions at drilling geology parameter acquisition unit collection analysis oil drilling scene and the sensor signal of geologic parameter, the record well depth, when boring, drilling parameter, mud parameter, logging parameters, draw drilling time curve, the monitoring drilling process, and give host computer to handle all data and put in storage.

Engine degasser is from the liquid level of motion tracking control module by detection engine degasser drilling fluid pot, regulate the height of degas chamber, it is relatively stable that assurance enters the drilling well liquid measure of degas chamber, for the well logging instrument provides stable gas, to improve the gas analysis quality, its output links to each other with the stepper motor input, and stepper motor links to each other with stirring motor by leading screw, stirring motor stirs drilling fluid, and the gas of deviating from is imported infrared total hydrocarbon gas analysis unit and carried out continuous on-line analysis.

Total hydrocarbon gas analysis data not only can be shown by LCD in real time in this unit, and can with drilling condition, geologic parameter, the drilling time curve of drilling geology parameter acquisition unit, show in real time, print, export after host computer be handled.

The main frame program step is:

The first step: as be newly-built well logging, the input well-name;

As being the continuation well logging, loading data judges whether well-name exists;

Second step: display routine runnable interface;

The 3rd step: carry out drilling geology parameter acquisition, record respectively by serial ports, total hydrocarbon gas concentration acquisition and recording, drilling fluid

Fluid level condition shows, record;

The 4th step: data are handled, are shown in real time;

The 5th step: drilling parameter, drag for sand data, total hydrocarbon concentration data warehouse-in, drilling time curve, total hydrocarbon curve plotting;

The 6th step: data, curve real time print.

As Fig. 4, shown in 5, engine degasser is from the motion tracking control module, mainly by power supply, liquid level sensor, single-chip computer control system, stepper motor and driver thereof are formed, its circuit is connected to, the p1.6 of single-chip microcomputer, p1.7, p2.0, p2.1, the p2.2 end links to each other with motor lifting control circuit input respectively, carry high-low level, pulse signal and lifting control instruction, motor lifting control circuit output links to each other with the stepper motor driver input, the output of stepper motor driver links to each other with stepper motor, and stepper motor is connected to drive electricity with electric running thick stick and takes off the degas chamber lifting; Liquid level sensor detects input circuit with high liquid level respectively, low liquid level detects input circuit and A/D change-over circuit input links to each other, high, low circuit detect input circuit respectively with the INT0 of single-chip microcomputer, the INT1 port links to each other, the A/D change-over circuit links to each other with P2.5-P2.7, single-chip microcomputer P1.0, P1.1, P1.2, P1.3, P1.4 also links to each other with the keyboard and display panel of this unit, with the display system duty, as liquid level abnormal alarm state, the liquid level superelevation, liquid level is ultralow, A/M (control automatically/manually control) and C/N (controlled/off line) state etc., when manual state of a control, can pass through ↑, ↓ button is manually controlled electricity and is taken off the degas chamber lifting, and single-chip microcomputer links to each other with main frame is two-way by the RS232 mouth;
