DTU in petroleum prospecting domain application
Origin: Input time: 07-06-10 02:12:08English version

1. backgrounds

The oil field is by the oil gas production primarily, the collection exploration, the development, the construction work, the rear service auxiliary production, the diversified management, the socialized service are a body, specialized class complete state-owned extra large type enterprise. The oil field exploration, the well drilling, the oil well logging, the logging and so on are the field work, the fluidity strong, dispersible, the distance is long, between the job location and company's information exchange does not have the good solution since long ago.

This case row mainly aims at the petroleum the exploration, causes the administrative personnel on by to observe the oil well survey condition as necessary through the configuration software realization in the office through this system. The system will be allowed to be direct-viewing the survey data display through the graph way for the correlation staff, and has provided the massive forms and the data analysis controls.

Because explores the scene generally all in the condition comparison abuse poor open country, therefore, the system has used the GPRS/CDMA wireless network, the final process analysis comparison, has used the GPRS networking pattern, explores the scene to be allowed to survey the data through GF-2008W DTU by the GPRS way the data transfer to the data monitoring center.

In view of to the above situation, center the petroleum petroleum prospecting research institute unified purple golden bridge software to implement below the plan.

2. solutions

1. systems structures:

The overall system mainly used, now the data acquisition card (self-restraint), network communication facility GF-2008W (GPRS DTU), GPRS the Modem monitoring center disposition is PC machine and "purple golden bridge configuration software".

Information gathering station

The 1> information gathers the substation:

Refers is the scene some well. Mainly used the data acquisition card (self-restraint), night of body probe, resistance probe, GPRS DTU and so on.

2> monitoring center master station:

Supports with Internet IP address PC machine, and is loaded with "purple golden bridge configuration software" and so on.

GPRS the data transmission terminal DTU function introduced that,

A, function:

1. standards AT order contact surfaces, convenient programming;

In 2. TCP/IP Internet inlays the agreement stack, with ease interlocks;

3. RS232 connection way, simpler communication way;

4. passable strings mouths promotion procedure.

B, performance:

1. uses the low power loss high performance CPU to make the processor, 16 interior data bus, 128KBSRAM, 512KBFLASH, but high speed processes the agreement and the mass datas;

2. supports entire is transparent and the frame form data transmission;

3. supports TCP, IP, PPP, ICMP, UDP, TELNET, the HTTP agreement stack;

4.1 conform to ISO7816-3IC card standard SIM 卡座, supports conforms to GSM11.11 and GSM11.10, the standard SIM card;

5. simplifications connection designs, use the general 232 connections and simple AT order the interactive contact surface;

6. has supplied the more convenient power source connection outside, then uses hangs the power source. Also may from string together the mouth straight to receive the electricity;

7. entire machine power losses are smaller than 3W;

8. has consummated the false digit dialing which in the GPRS network appears, automatically falls the line to open again, long-distance awakens and so on the function;

9. supports long-distance controls and dynamic domain name analysis;

At the same time 10. has inserts the type system request in, may provide sets at the type module (not to bring outer covering, passable has inserted needle with to insert type direct system to be connected).

11th, at the same time also has the software and hardware dually 看门? when DTU cannot the normal work, can the automatic power failure replacement.

3. system functions

Below in view of to the above solution, the system should realize the function:

Real-time data analysis, trend analysis, in history data analysis, hardness index value processing, report form function, dynamic disposition equipment.

1. real-time/history data analysis

The system wants real-time gathering "the information to gather the data which the substation" transmits, then the data which gathers after processing, turns the hardness index. After also must the temperature value, the resistance value which gathers, and the computation ore commensurability value stores the database. Because the system to the timely request is not very strong, only wants pointed to suppose the definite value to the hardness index to carry on processing. Therefore, may use a data to carry on the history and the real-time analysis through the historical data module unification.

This is time the system movement data history picture:

2. trend analyses

The use trend analysis module, will gather the temperature value or the resistance value, or the hardness index value which will obtain after the computation carries on the trend analysis.

This is time the system movement data trend analysis picture:

In 3. hardness indices value processing

Will establish the flood water mineralization and the surface water hardness index will obtain the ore hardness index after the computation to suppose the definite value, after whenever the current equipment hardness index achieved will suppose the definite value all to have to carry on the record, and will have to preserve the recorded time, the system initiation time, will extract the time difference value, in order to solve this problem, will use will be stores the data the relational database.

4. report forms functions

Will be connected the equipment data to derive the form module from the relational database, and will be allowed to output the form in content Excel, will prepare later to analyze the use.

In the hardness index value processing and the report form are does in a picture, in the hardness index value processing has used the massive scripts.

This is time the system movement hardness index report form picture:

5. Dynamic disposition equipment

Because each time surveys the use to suppose the service number one not to be fixed, therefore must through the system hypothesis parameter dynamic disposition equipment. May carry on the correlation establishment through the system parameter according to the disposition.

This is time the system movement parameter disposition picture:

6. System mode demonstration

Request display system all equipment have the movement situation, system support biggest equipment data item, but also has some stand prompt information and so on.

This is time the system movement equipment information picture:

Time system movement main contact surface:

Has provided the good chart in the host contact surface, may use staff's direct-viewing observation each well the real-time hardness index change.

3. conclusions

In the entire supervisory system, has mainly used configuration software and GPRS passes on terminal DTU without the line number, various well heads the data which gathers the scene transmit through DTU to the monitoring center, thus realizes various single well condition centralism monitoring, big reduced personnel investment, and facilitated the staff to carry on the management, will be able prompt the survey information to transmit to the monitoring center, the enormous enhancement survey efficiency, the overall system investment quite has been simultaneously small.
