摘要
In this paper, the key problems confronted with the natural gas exploration of mid-deep strata in the Yinggehai Basin were discussed. Strategically, a couple of policies gaining access to the success of natural gas exploration were proposed as follows: 1) to look for payable facies belts and predict good reservoirs by using approaches of seismic sedimentology; 2) to fully understand variations in physical properties caused by heterogeneity in reservoirs and search for distributional disciplines of good reservoirs by analogy with various reservoirs; and 3) to use high-precision 3D seismic data to try prestack inversion on the basis of petrophysical studies so as to improve the reliability of hydrocarbon detection and the precision of gas reservoir prediction.
