Bohai drilling comprehensive logging chromatography instrument to achieve localization

On December 1st, Bohai drilled four on-board gas measuring instruments equipped with Dema series chromatographs to reach the Changqing market and formally took posts. This indicates that the Demar series chromatograph independently developed by Bohai Drilling Co., Ltd. has achieved mass production and changed the history of the importation of the core components of the Dema Integrated Logging System.

Chromatography is one of the core components of Bohai Drilling Dema comprehensive logging equipment and has always depended on imports, which greatly limits the production, sales and maintenance of the instrument. In the past, the state parameters of the chromatograph were directly indicated less, most of the parameters needed to be measured with the instrument, and the error was very large. The operator was required to have rich field experience, the operation process was time-consuming and laborious, and the error was easily generated.

In response to these problems, Bohai Drilling Co., Ltd., through intensive research, successfully developed the Dema series of chromatographs, broke through the traditional analysis and control system using the two technologies of the rod valve and the rotary valve, and developed the need for high-pressure motive gas, the theoretical life of more than 50 million times, volume The 50% smaller, faster response multi-channel electromagnetic control valve realizes a sensitivity of 5PPM, a rapid analysis cycle of 30 seconds, and 15 seconds less than before. Field tests show that Dema Chromatograph has reached the level of similar products in the world.
