The “World Petroleum Award†was selected by the “World Oil†magazine and was selected once a year to honor technological achievements, events and individuals that have made outstanding contributions to the petroleum industry in the previous year. Historically, the "World Petroleum Award" has always been monopolized by Shell, Halliburton, Baker Hughes, Schlumberger, Weatherford, and other top international oil companies or petroleum engineering and technical service companies.
In recent years, China National Petroleum Corporation has repeatedly won the “World Petroleum Award†nomination and demonstrated its technological R&D capabilities in the world oil industry. In 2003, the "High Pressure Water Jet Radial Horizontal Well Drilling and Completion Technology" in Liaohe Oil Field was nominated for the "World Petroleum Award" for the best drilling/completion solution award. In 2005, the results of the Exploration and Development Institute's “Use of Earthquake Attenuation Information to Detect Gas Reservoirs†entered the final list of the “World Petroleum Award†Best Exploration Technology Award.
For the first time, CNPC won the “World Petroleum Awardâ€. In 2007, the results of Liaohe Oilfield's “Enhanced Recovery by Flue Gas†was honored in the competition with Schlumberger and Halliburton. Received 2006 "Best Mining Technology" award.
On October 16, 2008, the 2007 World Petroleum Prize will be announced in Houston, United States. It is reported that a total of 13 awards such as “Best Development Plan Awardâ€, “Best Exploration Technology Award†and “Best Data Visualization Plan Award†have been established. On the eve of National Day, the Tuha Oilfield Engineering Technology Institute received an invitation to participate in the “World Petroleum Awards†awards meeting. It is reported that with the "innovative jelly valve technology" at the same time selected the "new thinking award", there are four companies from Schlumberger and other technical achievements.
In the drilling, completion, and killing operations of oil and gas wells, it has been necessary in the past to use mud, kill fluid, and casing valves to balance wellbore and formation pressures to ensure construction safety. However, these methods either easily contaminate the oil and gas layer, or they are expensive and complicated.
The innovative “frost valve technology†independently researched and developed by the Tuha Oilfield Engineering and Technology Research Institute uses a chemical method to configure a type of jelly to achieve isolation between the oil and gas layer and the wellbore, effectively preventing the infiltration of the upper kill fluid. Pollution of oil and gas layers can also prevent the outflow of gas such as hydrogen sulfide in the formation. What's more worth mentioning is that when the tubing and drill pipe penetrate the jelly layer for follow-up operations, the jelly that replaces the casing valve is like a “Transformerâ€, and it is closely attached between the pipe string and the casing. Seal the entire process.
The successful research and development of the "innovative jelly valve technology" not only drastically reduced the cost of drilling, but also simplified the well completion process, and achieved good results through the field application of five wells. In a major field trial of CNPC's 2007 underbalanced nitrogen drilling, the nitrogen drilling section exceeded 200 meters, the mechanical drilling rate was 3.4 times that of the neighboring wells, and the crude oil production after drilling increased by 146%.
Oilfield drilling experts believe that the “innovative jelly valve technology†concept was ingenious and created a new way of gas drilling and completion, providing new ideas and technical means for low-cost underbalanced drilling and oil and gas layer protection during completion. The significance of promotion.
The "World Petroleum Award", which is hailed as the "Oscar of the oil industry," is one of the authoritative awards in the international petroleum technology community. On October 8, the reporter learned from the Tuha Oilfield Company that the "Innovative Gel Valve Technology" of the Engineering Technology Research Institute was nominated for the 2007 World Petroleum Award for "New Thinking Award."
