Abstract
The utility model relates to a connecting device of a wireless drilling inclination measurement system and a comprehensive well logging instrument, which comprises at least one sensor, a decoding PC computer and a well logging computer. The utility model is characterized in that at least a sensor and a high speed sensor are connected with a well logging instrument computer through a CAN field bus, and the well logging instrument computer system is connected with a decoding PC computer. The utility model has the advantage that the CAN field bus is adopted; only one cable is required; the wiring is convenient; the cost is saved; the bus system adopts the standard communication protocol; the anti-interference performance is high; and the expansion can be easily realized; and the connection between the wireless drilling measurement instrument and the well logging instrument can be realized without changing the hardware structure of the collection system of the original well logging instrument.
Description
Technical field
The utility model relates to the coupling arrangement of a kind of wireless drilling deviational survey system and comprehensive logging instrument, relates in particular to the wireless drilling deviational survey system in a kind of oil drilling and the coupling arrangement of comprehensive logging instrument, belongs to the petroleum drilling technology field.
Background technology
Wireless drilling inclinometers device (MWD) can in time be measured in drilling process, promptly do not stopping under the brill situation, mud pulse generator sends to ground with the data that the down-hole probe records, and after the machine system acquisition is handled as calculated, obtains real-time well bore parameter and formation parameter.Steering tool can be measured inclination angle, azimuth, tool face azimuth and the stratum natural gamma intensity of well bore in drilling process, for the drilling well of high angle hole and horizontal well in time provides well bore parameter and formation evaluation data.This instrument is in directional well and horizontal well drilling operation, for improving bit speed and guaranteeing the requisite technical equipment of drilling quality.
Comprehensive logging instrument is the on-the-spot a kind of large-scale electronic instrument that uses of oil and gas well drilling, directly gas, drilling fluid, engineering and the geologic parameter of measuring has 30 multinomial, the comprehensive logging instrument investigative range that can make comprehensive logging instrument that combines with measurement while-drilling instrument extends to underground from ground, its function is improved, for drillng operation provides the real-time guiding of creeping into.
Like product in the market adopts the real-time acquisition system based on single-chip microcomputer mostly, after sensor signal carried out A/D conversion, pass to well logging instrument PC by serial ports, as shown in Figure 1, first sensor 1-N sensor N is connected with the decoding PC by acquisition controller respectively, the decoding PC is connected with the well logging computer system, and its shortcoming is complicated for wiring, and anti-interference is not strong.
Summary of the invention
It is convenient that the purpose of this utility model provides a kind of wiring, the wireless drilling deviational survey system of strong interference immunity and the coupling arrangement of comprehensive logging instrument.
For realizing above purpose, the technical solution of the utility model provides the coupling arrangement of a kind of wireless drilling deviational survey system and comprehensive logging instrument, comprise at least one sensor, decoding PC and well logging computer, it is characterized in that, at least one sensor is connected with well logging instrument computer by the CAN fieldbus with high speed sensors, and the well logging computer system is connected with the decoding PC.
The utility model is on the basis of the well logging instrument (CMS) with CAN fieldbus acquisition system, utilize high speed sensors, gather upright pressure signal at a high speed, and will stand and press the 29.3ms interval of signal with the mwd system requirement, send to the decoding PC through well logging instrument acquisition system by serial ports, after decoding software is decoded, send decoding parametrics such as hole deviation, orientation to the well logging instrument system by network, the well logging instrument system is deposited to it after receiving these data, and shows well track in real time.
The utility model has the advantages that:
1. adopt the CAN fieldbus, only with a cable, wiring is convenient, the saving cost.
2. bus system adopts standard communication protocol, and strong interference immunity is convenient to expand.
3. need not change original well logging instrument hardware of data acquisition structure, just can finish connecting of wireless drilling measurer (MWD) and well logging instrument.
Description of drawings
Fig. 1 is the connecting device structure schematic diagram of wireless drilling deviational survey system and comprehensive logging instrument;
Fig. 2 is the utility model structural representation.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment
As shown in Figure 2, connecting device structure schematic diagram for wireless drilling deviational survey system and comprehensive logging instrument, the coupling arrangement of described wireless drilling deviational survey system and comprehensive logging instrument, comprise N sensor, decoding PC and well logging computer, N sensor is connected with well logging instrument computer by the CAN fieldbus with high speed sensors, and the well logging computer system is connected with the decoding PC.
On the high speed sensors additional busses type sensor, sensor signal is converted to the data signal that meets CAN communication protocol, directly pass to well logging instrument computer by the fieldbus cable then, send to the decoding PC through well logging instrument computer system by serial ports, after decoding software is decoded, to decoding parametrics such as well logging instrument system passback hole deviation, orientation, well logging instrument computer system is deposited to it after receiving these data, and shows well track in real time by network.
