Brief Introduction To The System Configuration

The system is composed of four main parts, they are: a Control Rack, a Display and Operating Desk, a Power Supply Rack and a Truck Depth Panel SDDP-C. The Control Rack consists of a Perforating and Coring Panel (CSP), a Signal Switchover Cabinet (CIP), an Acquisition Interface Cabinet (GEP), an Electrode Array Logging Panel (DJXP), an Interface Cabinet of DITS (DEMP), an AC Power Cabinet of DITS (ELGAR), a USP and an AC Power Control Panel (ACCP); The Display and Operating Desk consists of a Consolidated Industrial Computer, a consolidated LD and a Network Exchanger; The Power Supply Rack consists of a Control Panel of DC power (DCCP), a Power Cabinet of Down Tools (TPS), 4 DC Power supplies, a Digital Oscillograph and a Plotter.

Operating Principle

1. Logging Computers

530 Logging Main Computer and 530 Auxiliary Logging Computer form a dual-computer system for 530-series, 520-series, 521-series and cased hole production loggings, perforating and coring, and other domestic logging. It adopts Windows-2000 operation system as an open platform. The 530 Logging Main Computer is the CPU of the system, and it completes the software initialization of the main control module and DSP modules etc. after starting the system; it completes the orderings of display, plotting recording and management of various data, as well as of the disposition of tool strings, power on the down tools, calibration of down tools and operation of pad-mounted device during logging. The 530 Auxiliary Logging Computer can exchange data with 530 Main Logging Computer through a Net Exchanger and process the data while logging. It can promote logging efficiency. If the 530 Main Logging Computer fails, the 530 Auxiliary Logging Computer can quickly be connected into the system through the ether net port to complete the logging operation. With the switchover, the plotter can be separately connected with 530 main and auxiliary logging computers for log plotting after logging.

DITS (EXCELL-2000) Main Logging Computer is a special logging computer of DITS–series tools, it is connected with the main control computer PC104 through ether net to complete the display, plotting, recording and management of relative logs, and to control down tools.

2. Depth System

In the Acquisition Interface Cabinet, the depth system, with the core of PC104 computer board, completes the receiving, calculating, correcting, presetting and correcting against cable slip and vibration, and sends the corrected depth increment interrupt to the 530 Main Logging Computer and PC104 Main Control Computer for calculation, meanwhile it can send the present depth, depth preset of key board, corrected depth value to the PC104 main control computer.

It is different from the depth-driving logging program of 530-series (520), 521-series tools, the DITS tools of Halliburton use time-driving logging program, so the depth system should print the time mark on the depth value and then send it to DEMP Interface, the DITS-series logging program can then identify the information of depth and other data.

The depth system can meanwhile acquire magnetic marks, tension, and pack them with depth signal, then send them to Truck Depth Panel for display there through RS-232 series port.

Main Characteristics

1. Complete Functions, Advanced Performance And Strong Compatibility

The system can be compatible with various open hole convenient logging series’ and production logging tools of Huanding, and DITS-series convenient and imaging logging tools of Halliburton. It will also be compatible with some special tools and IQ-series tools of Halliburton in future.

2. Various Technical Measures Ensure The Reliability Of The System

l Adopt the designs of CPLD, DSP for integrating the system;

l The designs of module and independent channel avoid the interference in the system, and it is a convenient way for system maintenance;

l Adopt mature technology for the system stability. The system is designed on the base of CJS-VA Computerized Logging Surface System of Huanding, and the DITS-series interface is directly introduced here from Halliburton Company;

l Use high reliable equipments and devices, such as consolidated industrial computer, consolidated LD, special wide-band and wide-voltage UPS, imported AC and DC power supplies, all the imported connectors in the cabinets and controlling devices on the front panels.

3. Adopt Advanced Computer Net Technology for the Optimized Systematic Structure.

Both the acquisition and depth system use embedding computer PC104, several computers with net exchanger form a net system to complete various logging functions, and the acquiring system can control and monitor related parts through RS485 Series Net.

4. WIN2000-Vxwork-DSP Software System Enhances Real-Time Function Of System Logging.

5. Better Structure Design of Human Nature.

The desk design enlarges the operation space and improves the comfort for operators. The front panels are made of stainless steel. The system has very good outline.
