摘要:The reservoirs in the AD gas field on the right bank of the Amu Darya River in Turkmenistan are dominated by reef-shoal limestone. During the development stage,the pressure and production of the gas reservoirs from wells vary enormously, which shows a strong heterogeneity of the reservoir and makes efficient development difficult. Using the characteristics of seismic response on reef-shoal and single-well facies to describe sedimentary facies, and carrying out high-resolution geostatistic inversion based on facies control to generate P-impedance cubes under the constraints of production and test data, the distribution of reef-shoal reservoir and the superposition between reefs are characterized in detail based on high-resolution inversion results, which will guide further study of the development plan and water control of the reservoir. This method makes full use of the research of dynamic and static data. Compared with traditional methods, it improves the accuracy and reliability of the reef-shoal reservoir characterization, and provides strong support during development stage.
