[0096]
[0097] Table 1
[0098] For example, in Table 1, oil and gas zones A and M are used. Substituting the relevant parameter factors of the benefit and efficiency parameters of oil and gas zones A and M into formulas (1) and (2), the benefit and efficiency parameters of oil and gas zones A and M are calculated respectively, where P... A =1+0.51+0.8+0.95=3.26, R A =0.43 + 0.83 + 0.50 = 1.76, that is, E A =P A *R A =5.74; P M =1+0.31+0.79+0.86=2.96, R M =0.55 + 0.75 + 1 = 2.30, E M =P M *R M =6.81, indicating that oil and gas zones A and M are high-efficiency and high-quality exploration areas, and their investment deployment plans are worth learning from for other areas. Using the same method, calculations were performed on the other oil and gas zones in Table 1, revealing that oil and gas zones G, H, I, and N, as well as oil and gas zones I, G, and L, all have relatively low comprehensive evaluation parameters for quality and efficiency improvement. Specific analysis shows that the efficiency parameters of oil and gas zones G, H, I, and N are relatively low, requiring improvements in organizational management, including optimizing benchmarking management, promoting technological innovation, and deploying forward-looking plans. The benefit parameters of oil and gas zones I, G, and L are relatively low, requiring optimized investment deployment plans, including increasing investment in key areas and high-efficiency exploration zones, and strictly controlling costs and the number of deep wells.
