Other Feature

The analyzer is equipped with dual flammable gas detection alarms—one inside and one outside the system—for enhanced safety and real-time hazard monitoring. Additionally, the analysis position features a protective cover to shield operators from high temperatures, ensuring full protection during testing.

The instrument incorporates a patented BEST manifold design, providing exceptional integrity and minimizing dead volume to improve measurement accuracy. The all-stainless-steel gas pipeline system utilizes VCR metal hard connectors for superior sealing, and leak detection is conducted with an Inficon helium mass spectrometer, ensuring a high level of system airtightness and reliability.

Equipped with an imported high-precision pressure sensor, the system offers an impressive accuracy of 0.01% FS and long-term stability of 0.025% FS, ensuring precise pressure measurements over extended periods of use.

A non-barrier pollution prevention device, combined with an anti-pumping software program, eliminates the risk of volatile sample boiling under high vacuum conditions. This design prevents contamination of the valve and pipeline system, preserving the integrity and airtightness of the entire system.

The standard sample tube filling rod is equipped with a filter to reduce the free space volume in the sample tube. This effectively prevents sample splashing or contamination of the instrument's internal components, safeguarding both the instrument and the integrity of the test.

A composition-based model for methane adsorption of overmature shales in Wufeng and Longmaxi Formation, Sichuan Basin Author links open overlay panel Wenbin Jiang a b, Gaohui Cao a, Chao Luo c d, Mian Lin a b, Lili Ji a b, Ji Zhou a b

The Wufeng-Longmaxi Formation shale in Sichuan Basin is the main strata of shale gas exploration and development in China. Adsorbed methane is an important part of the total shale gas content. The influence of shale composition on adsorption characteristics is complex, and it is difficult to obtain a comprehensive understanding without a sufficient amount of data. In this work, the total organic carbon (TOC), X-ray diffraction (XRD) mineral analysis, and the excess methane adsorption isotherms with pressure up to 50 MPa at 40 °C of 106 overmature shale samples with TOC of 0.8%-9.0% and clay content of 2%-58% that belong to Wufeng-Longmaxi formation from 10 shale gas wells in Sichuan Basin, China are experimentally investigated and analyzed. New correlations found between compositions and methane adsorption characteristic parameters guide the establishment of a composition-based methane adsorption model that the excess adsorption isotherm of shale is the content-weighted sum of equivalent unit-content excess isotherms for organic matter and clay. With this model, the differences of excess isotherms of these two compositions and the differences of clay-contribution to methane adsorption for different sublayers are disclosed. It is beneficial to improve the accuracy of shale reservoir evaluation of studied blocks under the condition of limited coring and deepening the understanding of the underlying mechanism of methane adsorption characteristics.
