Academician Workstation Tour | Liuhe Team with the old oil area with new "skills"

What many people do n’t know is that today ’s“ hoe machine ”everywhere in Daqing is not picked by the oil flow, but the oil and water mixture. The above: 1 ton, 950 kg is water, only 50 kg of oil. The remaining oil is scattered, and the difficulty of mining is becoming more and more difficult. At present, the reserves and outputs of the high -moisture oil fields in my country account for more than two -thirds.

How to innovate and develop high -efficiency potential digging technologies for high -moisture oil fields and maintain continuous production? How to realize the orderly replacement of resources? How to cultivate a scientific and technological innovation team and leading talents in the direction of sustainable development?

In order to solve this series of problems, in March of this year, Daqing Oilfield introduced the "Sustainable Development Technical Research Research Research Research Research Research on the Local Oil Area", and jointly assaulted with the Chinese Academy of Engineering Liu He and his team to break through the key core technologies of restricting development. Breaking into innovative "unmanned areas".

Academician back to "home" for research and development

"The cooperation with Academician Liuhe has a deep foundation, which can be said to be successful." Guo Junhui, a technical expert of the Daqing Oilfield Exploration and Development Research Institute, told reporters.

As one of the leaders in the field of oil mining engineering in my country, Academician Liu He led the team to create a series of key technologies such as oil recovery engineering technology and management "continuous integration" engineering management model; ; Solving major problems in the development of the maximization of tailings resources and the development of low -quality reserves.

Before being transferred to the China Petroleum Exploration and Development Research Institute, Academician Liu He had worked in Daqing Oilfield for 27 years and had deep feelings for Daqing. In July last year, Academician Liu He and Professor Zhu Rukai successfully revealed the list of the first batch of major science and technology research projects in our province.

In recent years, Daqing Oilfield and Academician Liuhe have established a good foundation for cooperation in many fields such as the Key Laboratory of Heilongjiang Province, the China Academy of Engineering's key consultation projects. The high -quality and high -efficiency development of the Luxiang Old Oil Area has made significant contributions.

Based on the consensus to contribute to the sustainable development of the old oil field, in March of this year, the "Lu Xiang Old Oil Area Sustainable Development Technology Research Research Academician Workstation" was established. 10 experts in the academician team and 9 technical experts of the oil field began to overcome the "high water content old old old old old old old Technical problems in the field of oil field development "research".

CT to the oil layer

For more than 60 years of mining of oil fields, delicious and easy -to -eat resources have been eaten. What are the remaining "marginal reserves"?

"The surplus oil of the oilfield during the high water field is highly scattered. Precise positioning the remaining oil is the key to implementing precision development strategies and extending the life of the old oil field. It requires high -precision geological models and high -precision numerical simulation support." Personalized brother Fu Xian said.

The work team of the academician workstation for more than 3 months is being detained.

If you want to achieve precise "oil", "underground map" is essential. How to pass the authenticity and real time in real time? The “High -precision CT, NMR in situ -driven scan and digital infiltration simulation simulation” technology that is developed by the academician workstation can be quantitatively researched by accurately positioning the oil layer to make CT, and a quantitative research on multi -scale infiltration such as rock heart and pores, so as to create post -creation oil The theory of wisdom geology and infiltration provides theoretical guidance for in -depth development.

With the "Map", scientific researchers will improve the reliability and accuracy of the description of the oil collection through the comparison and analysis of massive development of dynamic data, and quantitatively study the types and distribution characteristics of micro remaining oil; Technology, accelerate the parallel processing speed of the simulation of oil collection, improve the accuracy and efficiency of the remaining oil simulation, and facilitate precise excavation of the remaining oil.

"Drive" oil and gas from the rock seam

In the breakthrough innovation of scientific research technology, Academician Liu He's most effort is the finest layered water injection technology. This technology has now iterated to the fourth generation in Daqing Oilfield, helping my country's stratified water injection technology to continue to lead internationally internationally.

What is "layered water"?

At the beginning of the oil and gas development, the strata pressure was enough to spray the oil and gas along the well. After the pressure decreased, it was necessary to replenish the energy by manually to replenish the energy. The most used way is to push water and "drive the oil and gas out of the rock gap."

Today, the fourth -generation fine layered water injection technology sets the monitoring, control, and communication in one, so that the "eyes" and "hands" developed by the oil collection can be extended to each section, achieving the section of the streaming flow and pressure of the water injection wells, and the pressure and other parameters of the water injection well. Remote real -time monitoring and regulation.

This technology can allocate hundreds of eloquence or even thousands of wells wirelessly. At present, 6 demonstration areas have been constructed in Daqing Oilfield, and a total of 503 wells are used.

Based on this research and development, the academician workstation is being separated from the underwriting oil and water spinning technology. This technology uses the spinning separation device to separate the oil water of the use of the production layer under the well. In order to be a small cycle between the lower layers and the interior of the well, subvert the traditional production model, realize the decrease in the amount of liquid in the ground by more than 70%, significantly reduce the energy consumption of machine mining, water injection, and transmission systems. Open a new model. In the tested oil wells such as Daqing and Dagang, the preliminary effects of adding liquid, oil increase, and reducing water.

Innovative technology, creative talents, and creative benefits, look forward to the sustainable development of the old oil zone in the Land -like Oil Area, to continuously radiate more energy, and help the old oil field to rejuvenate a new life.Source: Heilongjiang Daily
