Abstract

The utility model relates to an intelligent instrument for the depth of a drilling well, which belongs to electronic meters in petroleum industry. The intelligent instrument is mainly composed of a roller position sensor (4), a hanging load pressure sensor (1), a vertical pipe pump pressure sensor (2), a drilling parameter display (3), a collision preventing overhead travelling crane controller (5) and a single chip microcomputer processing system (6). Because the roller position sensor (4) combines a mechanical counter, a photoelectric encoder and a unit stepping mutation device, the utility model solves the problem that errors occur because of the impulse of external interference and the reinstallment of parameters caused by power failure. Thereby, the test accuracy is improved, and errors of the whole instrument are reduced.

Description

The drilling depth Intelligent Instrument

The utility model belongs to the petroleum industry electronic instrument, relates to a kind of drilling depth Intelligent Instrument.

At present, cylinder position sensor in the instrument of domestic detection drilling depth parameter is to adopt the pulsating electronic counter, processing parameter has only overhead three parameters in the well depth degree of depth, tourist bus height and shaft bottom, and the pulsed counter can not have a power failure when work, parameter is provided with pretty troublesome, and error is also bigger.

The purpose of this utility model provides a kind of drilling depth Intelligent Instrument, has overcome and resets and be subjected to external impulse disturbances because of power failure and produce the problem of mistake because this Intelligent Instrument cylinder position sensor adopts mechanical counter to combine with photoelectric encoder, individual position wheel stepping sudden change device.

In conjunction with the accompanying drawings the utility model is described further.

Fig. 1 is for boring and degree of depth Intelligent Instrument frame principle figure.

Fig. 2 is cylinder position sensor construction figure.

Fig. 3 is the software programming flow chart.

The utility model is to realize like this (such as Fig. 1), a kind of drilling depth intelligence Instrument, mainly by cylinder position sensor (4), suspending weight pressure sensor (1), pump charge Pressure sensor (2), rig floor parameter display device (3), colliding crown block controller (5) and monolithic Microprocessor system (6) forms, and cylinder position sensor (4) is installed in wire rope drum Axle (D) is located, and weight transduser (1) is installed in dead line device (A) and locates, pump pressure sensor (2) Be installed in high pressure vertical tube (B) and locate, rig floor parameter display device (3) is installed in rig floor (C) and locates, Colliding crown block controller (5) is installed in valve main valve (E) and locates. The cylinder position sensor (4) adopt three kinds of mechanical counter and photoelectric encoder, individual position wheel stepping sudden change devices Structure forms, and single-chip microcomputer microprocessor system (6) comprises hardware electrical equipment and software application Program, rig floor parameter display device (3) comprises the bright display screen of extra-high-speed, single chip microcomputer hardware Circuit, software application.

Utility model is because cylinder position sensor (4) adopts mechanical counter and light Photoelectric coder, individual position wheel stepping sudden change device combine, and have overcome because having a power failure and have again established Put the problem of parameter, improved precision, reduced error, owing to increased suspending weight Sensor (1), pump pressure pressure sensing (2), thus the pressure of the drill increased, and the geology sand sample drags for 12 important parameters such as get, basically satisfied wanting of drilling engineering desired parameters Ask.

An embodiment is described below: at first be to process assembling according to Fig. 2, to the single-chip microcomputer hardware in the main frame, display, printer, UPS etc. process assembling, carry out software programming then, debugging, emulation, work such as copy, the hardware composing of rig floor parameter display and software programming debugging, copy.
