DFS series products [DF (Drilling Fluid) Real-time/Automatic Monitoring & Digital Simulation/Analysis Intelligent Equipment] are intelligent equipment in the field of DF for drilling engineering in the oil & gas industry. As we all know, DF is known as "The blood of drilling engineering". DF is a non-Newtonian plastic fluid developed in artificial laboratory based on the determination of chemical formula with the water or diesel oil or synthetic oil or other stable liquids as basic fluid. The diagram shows the standard circulation process of DF on site of drilling engineering. Main functions of DF: ① Forming jet cutting formation; ② Lubricate/cool drill bit; ③ Circulate and carry out drilling cuttings; ④ Well control; ⑤ Form a stable artificial well bore; ⑥ The hydraulic power of directional BHA; ⑦ The medium of data & information about directional BHA back to the ground.

The demands for DFS system on drilling engineering field is determined by Current Situation of Oil & Gas drilling industry and Trend of Digital Strategic Transformation of the industry:

1. Industry Status

 ● Issues:

 √ "Field/Real-time/Full-automatic/Digital monitoring of DF performance parameters" and “Synchronous/Digital Hydraulic Descriptions/Analysis/Pre-warning of wellbore while drilling" can not be realized on the drilling engineering field, resulting in DF engineering complex uncertainty and weak controlling in the field, and finally form a direct economic loss equivalent to 3~5% of the total investment of drilling engineering;

 √ Due to the lack of Real-time/Continuous/Complete data of DF on the drilling engineering field, the data of other operations (Drilling/Logging/Mud logging/Directional well) in the field form certain degree of “Data Isolation", resulting in the accurate, continuous and efficient mode of “Data Support Service" not being performed completely and consistently.

 ● Challenges：Unconventional, Complex/Special geological structure/Lithology, Deep/Ultra deep oil & gas reservoirs are the new normal faced by World Oil & Gas industry at present; Solving above issues is one of the core technical challenges of whether the new normal "well" can be "Successfully, Quickly and Controllably" and whether the "Reserves" and "Productivity" can be finally implemented.

2. Industry Digital Strategy Transformation Trend

 ● In the field of engineering technology services of Oil & Gas industry, it is imperative to use Digital Transformation and Industrial Internet to promote the core competitiveness!

 ● Digital Transformation of drilling engineering in Oil & Gas industry, involving Equipment, Instruments and Liquids; Drilling Fluid/Drilling Engineering Field Digital & Intelligent Service System (DFS system) is one of the core intelligent equipment about Digital Transformation of "Liquid";

 ● In fact, the application of DFS series products is not "New Toy" for "Icing On the Cake" of Automation/Digitization/Intelligence Trend of drilling engineering, but the rigid demand that has plagued the drilling engineering field for many years, just like the rigid demand of DF solid control system and Logging System.
