From geology to engineering: a game-changing technique for fractured-porous carbonate reservoir in Central Asia
Through the reserch framework of "fundamental theory → technology research → engineering validation, the program presents a comprehensive approach for in-depth profile control in fractured-porpus carbonate reservoir, intergrating geological, reservoir, and engineering. In this research, the identification technology for low-angle fracture network connectivity and residual fluid occurrence in porous media has been established. A collaborative method and chemical system have been developed for the fractured porous carbonate reservoir. An integrated design method for in-depth confromance treatment, as well as an innovative intelligent control online injection and flooding technology, have been constructed.

The fracture distribution characteristics of various morphologies and scales were quantified, elucidating the distribution and existence characteristics of non-continuous gas phase in the throat as well as the adsorption properties of heavy components from degassed oil on the rock surface. A graded in-depth conformance treatment pattern for fracture-porous carbonate reservoirs was established, achieving a prediction accuracy for chemical agent dosage within 3%, with a application success rate of 100%. These findings were applied to typical fracture-porous carbonate reservoirs such as B oilfield and R oilfield, yielding significant economic and social benefits.
The team has won 3 provincial and ministerial scientific and technological progress awards, 1 provincial and ministerial scientific and technological innovation team award, 17 RIPED's scientific and technological progress awards, and has contributed an important force to the sustainable development of oilfield development in the Belt and Road countries.
