530-Series Super-combined Logging Tools, Section 1

It is an advanced logging technology of high efficiency, high integration and high ratio of performance to price. In this area, the system jumps in to the advanced line in the world. The advantages of the system are:

SUPER-COMBINATION: One run gets 27 logging curves.

HIGH INTEGRATION: Three main measures: Common circuit sub controls multi-probes; Single hydraulic pad-mounted device drives a combined probe of Litho-density logging and Micro-spherically focused logging; A lot of second integrated circuits are used. They improve the stability and reliability of the system.

LIGHTER AND SHORTER: Better operated, and reduce the drilling bag.

HIGH RATIO OF PERFORMANCE-PRICE: With maintenance or improvement of the performance of 520 series tools, the ratio of performance-price is improved.

530 series logging strings consist of cable telemetry/gamma ray combined tool, temperature/tension/Rm tool, common electronic circuit section 1, gamma ray sonde, compensated neutron sonde, litho-density and micro-spherically focused logging combined sonde, hydraulic pad-mounted device, common electronic circuit section 2, borehole deviation logging sonde, dual latero-logging sonde, high resolution sonic logging sonde, dual induction logging sonde, four independent are caliper tool and flexible joint sub etc.. Following diagram shows the brief configurations of 530 series strings.

The 530-Series Super-combined Logging Strings consist of three sub-series. The resistivity sub-series consists of dual laterolog (or Dual induction tool) and micro-spherically focused logging tools; The porosity sub-series consists of litho-density, compensated neutron and high-resolution acoustic logging tools; And the auxiliary logging series consists of spectro-GR or natural-GR, auxiliary logging cartridge, SP, 4-independent arm caliper and borehole deviation logging tools.
