Recently, the first deep-ocean drilling vessel “Dream” independently designed and constructed by China officially set sail in Guangzhou, which marks a significant breakthrough in key technical equipment for China’s deep-sea drilling.As a petroleum equipment enterprise that has been deeply involved in the field of oil and gas exploration for many years, Shenkai has facilitated China’s deep-sea oil and gas exploration by providing the core equipment SK-3Q07 hydrogen flame chromatograph and its supporting SK-7H06 constant volume deaerator for the vessel “Dream”.

It is reported that the vessel “Dream” , as a “the pillars of a great power” supporting the construction of a strong maritime country, can be called a “national mobile laboratory”. It has the capability to navigate in non-restricted waters worldwide and the drilling capability of 11000m in sea areas. In the future, it will undertake ocean drilling mission in major national science and technology projects and international scientific programs, make breakthroughs in more than ten key technologies, and is the most advanced ocean drilling vessel in the world.

The chromatograph is the core equipment of gas logging, which can reflect the changes in formation oil and gas in a real-time manner through online detection of the natural gas content carried by the returned drilling fluid in the formation, and provide intuitive and accurate oil and gas information for reservoir assessment. The SK-3Q07 hydrogen flame chromatograph has a 15s ultra high speed gas detection and analysis capability. At the same time, through differential analysis of drilling fluid inlet and outlet, it can effectively avoid the influence of organic components in the drilling fluid (especially oil-based drilling fluid) on oil and gas display.

The SK-7H06 constant volume deaerator uses a hose pump to continuously suction drilling fluid into the deaeration cylinder for mixing and deaeration. The drilling fluid processing capacity can reach 12L per minute, and can be matched with high-precision chromatographs such as SK-3Q07 to achieve quantitative interpretation of formations and oil and gas, making the detection data more accurate.

In the future, Shenkai will continue to uphold craftsmanship, strengthen technological innovation and research, improve product performance and quality, and contribute Shenkai’s strength to the improvement of China’s capabilities of “deep-sea exploration, deep-sea production, and deep-sea development”.

Chromatographic Logging Solutions

For the identification of thinner oil and gas reservoirs, as the drilling speeds increase, the chromatographic analysis cycle can be shortened to improve the formation resolution. For the identification of heavy oil reservoirs and reservoir water content, online continuous analysis of light hydrocarbons can be provided. We provide various high-performance and high-precision chromatographs according to different logging application requirements, including 3Q05, 3Q06, 3Q07 hydrogen flame chromatographs, CHROMWIZARD wellhead chromatographs, with chromatographic analysis cycles of 90s, 30s, and 15s, and online analysis of chromatographic components for C1—C8, C1—C6, C1—C5.
