Popis: |
It is common that bottom water of the carbonate reservoir coned caused the flowing wells stopped or bursting watered out even abandoned. Research suggested that it is worked to delay the bottom water coned with the help of flowing barrier while injected, to cure the “dying wells” and “long-time shut-in wells” with a lower cost and much more efficient method. Based on the complex and unique pore structure of the carbonate reservoir, combined with the theoretical fracture-cavity multiscale seepage law research, conceptual models of “fracture inject and cave product” and “cave injected and cave product” were put forward and built, the calculation method of reasonable water injection parameters was given, further research to prove the feasibility and validity of the method by actual production data. It suggested the conceptual models can reflect the actual multiscale seepage of carbonate reservoir and the calculate method can be used in selecting reasonable water parameters very well. |
