Description：
|
Aiming at the new oilfield development situation that development well is almost shallow well, deviation well and horizontal well and the number of logging items decreases, various operation modes are adopted, like drilling pipe handling, pumping-out and so on, which makes the time-sensitivity and cost control increase. For the above situation, Huanding Energy Services develops the 531 system. Based on 530 system, 531 system absorbs design technique of slim tools and simplifies the function and configuration. Transmission mode and power supply mode are different from 530 system. 531 adopts independent power sub and integrates electrical circuits and sondes. This system basically maintains the functions of 530 system and also shortens the length of the tool string. Also, the tool string is combined flexibly. The tool string can be reduced according to customer demands.

Surface System Briefly IntroductionDownhole Tools CharacteristicsDownhole Tools Briefly IntroductionTool String Combination Mode
This surface system is simplified version, just having logging function with single cabinet, extensible electrode array logging panel, perforation, coring panel and other functional module. This system consists of interface cabinet, power supply cabinet, plotter and computer or alternatively laptop. The console adopts desktop layout, which is convenient for operation. The computer screen, keyboard and mouse lays on the desk.
Meanwhile, portable structure is alternative.
interface cabinet：
power supply and signal channel control
BPSK modulation and demodulation, 100Kb/S
full waveform acoustic sampling, 2.4M and 1.2M are alternative.
analog signal sampling, 16 channel, 12 bit resolution
logging data preprocessing
it can be deployed with power supply of 35Hz, used for connecting to 530 tools.
power supply cabinet：
AC main power supply 600VAC/1A，50Hz；
AC auxiliary power supply 600VAC/1A，50Hz；
hand knob controlling
SDDP：
It is used to provide the information about depth and wellhead tension.
For the application of portable system, depth processing panel can be set in interface cabinet.
The tool string maintains the basic three resistivity logs, three porosity logs, three shale indication logs, namely dual laterolog tool, micro-spherically focused logging tool, compensated density(litho-density)logging tool, high resolution acoustic tool, telemetry gamma ray tool, SP and caliper deviation tool.
It adopts power supply sub. Besides TGR, other tools uses power supply of 48VDC. Each tool uses DC/DC as power supply, leaving out space for transformer, so that the whole tool string shortens 10m.
4-arm caliper cartridge contains deviation sonde and circuit. Caliper deviation tool is compound tool with total length of 3.5m.
Lateral cartridge is set into sonde mandrel and power supply of 35Hz moves into downhole, decreasing controlling steps.
High resolution acoustic tool has one transmitter and five receivers. It also has the function of CBL-VDL. The total length is 3m. Also, it is used as upper electrode.
