Four invention patents of Jidong Oilfield Research Institute have been authorized by the state

In recent years, Jidong Oilfield has persistently strengthened scientific and technological innovation, strengthened independent research, and effectively solved the technical problems that restrict the current and future development, and the four invention patents of Jidong Oilfield Exploration and Development Research Institute have been authorized by the state this year, which is an important achievement of the Institute to strengthen scientific research management, improve the ability to tackle major projects, and vigorously promote the construction of scientific research teams, effectively solve practical problems in scientific research and production, play the leading role of "one department and three centers", and provide technical support for the transformation and upgrading of oilfields
。

It is understood that the four invention patents authorized by the State Intellectual Property Office are: "Method and Device for Determining Quality Factors", "A Simulation Device and Analysis Method for Superposition of Magma Bottom and Elongation", "Well Network Adjustment Method and Device", and "An Experimental Method for Identifying the Wave State of Chemical Flooding Front"
.

Among them, the method and device for determining quality factors is used to process seismic data, which significantly improves the resolution of seismic data and makes the wavegroup relationship clear, which is conducive to the improvement of subsequent reservoir prediction accuracy and the implementation of favorable target distribution
.
This technology effectively guides the establishment of quality factor fields in Nanpu No.
4 structure and pick-up sub-concave, and the actual seismic data processing effect is significantly improved, which provides a solid data foundation
for supporting the deployment of exploration and development wells in these areas.

"A Simulation Device and Analysis Method for Superposition of Magma Bottom and Elongation" simulates and reproduces the actual fault structure, better explores the fault structure pattern and development mode under the influence of igneous rocks in the Nanpu Depression, and is conducive to analyzing the relationship between key events and faults such as source rock maturation, hydrocarbon transport, and accumulation into reservoirs, which is helpful to guide seismic interpretation in the target area and for the prediction
of favorable oil and gas zones 。 This technology effectively guides the re-identification and optimal selection of middle and deep volcanic institutions in the Nanpu sag, among which a total of "3 layers and 9 phases and 17 sets" igneous rock bodies were identified in the 280 area of Nanpu, which supported the overall deployment of four wells integrating pre-exploration and evaluation in the area, and effectively expanded the exploration space
of pyroclastic rocks.

"Well Network Adjustment Method and Device" This method aims at equilibrium displacement, comprehensively analyzes static and dynamic anisotropy characteristics, combines theoretical research with numerical simulation, and carries out the research on differential adjustment methods of plane encryption adjustment and interlayer subdivision and recombination, which provides technical support
for improving the development effect of strong heterogeneous multi-layer sandstone reservoirs, improving the level of reservoir development, and realizing balanced reservoir displacement.
The patent guides the preparation of the reservoir adjustment plan for water injection development in Jidong Oilfield in 2018~2021, provides certain guidance for the implementation of new drilling, and provides certain technical support
for the completion of oilfield development and production tasks.
The implemented plan has produced a total of 319,000 tons of oil, produced 85.
48 million square meters of natural gas, and after the introduction of the sharing coefficient of 0.
02, the total new profit since the application of the patent is 2.
64 million yuan
.

"An experimental method for identifying the ripple state of chemical driving leading edge", this method is based on the change of resistivity curve, and then obtains the wave position
of the driving leading edge.
This method can detect the concentration of chemical agents at the leading edge of different positions of the core, which is suitable for the high water saturation environment of chemical flooding, with low cost, simple operation and strong repeatability
.
This technology effectively guides the adaptability, potential evaluation and scheme preparation research of chemical flooding enhanced oil recovery technology of different types of reservoirs in Jidong Oilfield, and provides technical support
for greatly improving oil recovery and improving the development effect of Jidong Oilfield.
