As shown in fig. 1, the invention provides an injection-production well pattern optimization design method for a fracture-cavity type oil reservoir space structure, wherein a plurality of wells are arranged in an oil field block, and the injection-production well pattern optimization design method for the fracture-cavity type oil reservoir space structure comprises the following steps: s1): determining a plurality of initial injection-production schemes according to the position of each well or the type of the reservoir body of each well; s2): respectively calculating the communication degree between injection wells and production wells of each initial injection-production scheme; s3): respectively calculating the Gini coefficient of the communication degree between the injection wells and the production wells according to the communication degree between the injection wells and the production wells of each initial injection-production scheme; s4): and selecting the initial injection-production scheme with the minimum Gini coefficient as the final injection-production scheme.
Specifically, as shown in fig. 2, in step S1, a plurality of initial injection-production schemes are determined according to the principle of "low injection and high production", a plurality of initial injection-production schemes are determined according to the principle of "the well of the fractured reservoir is a water injection well, and the well of the karst cave reservoir is a production well", and/or an initial injection-production well pattern scheme may also be determined according to the production conditions of the wells. In the step S1, the above factors may be considered together to determine a plurality of initial injection-production well pattern schemes, that is, a well with a low position, a fractured reservoir, and poor production conditions (water content > 98% or oil production <1t/d) is selected as the water injection well; and selecting a well with a higher position, a karst cave type reservoir and a good production condition as an oil production well. In one embodiment, one of the plurality of wells is selected as a water injection well and the other of the plurality of wells is selected as a production well in each of the plurality of initial injection and production scenarios.
Further, in step S2, the conductivity is inverted by fitting the production based on a conductivity and a dynamic index prediction model established for the well control volume, wherein the conductivity is a parameter indicative of the degree of communication between wells,

And further, respectively drawing Lorentz curves of the communication degrees of the injection and production wells according to the calculated communication degrees of the injection and production wells of each initial injection and production scheme, thereby obtaining the Keyny coefficient. In the present embodiment, as shown in fig. 3, when the lorentz curve is plotted, the communication degrees are first arranged from small to large, the abscissa is the cumulative percentage of the well pairs, and the ordinate is the cumulative percentage of the communication degrees (fig. 3). And comparing the keny coefficients of the communication degrees between the injection wells and the production wells in different initial schemes, wherein the keny coefficients are areas formed by the curves and the diagonal lines in a surrounding mode (shaded parts in the figure 2).

Compared with the prior art, the reservoir type and the well production condition of the injection and production well drilling are considered, and the inter-well communication degree is also considered. The scheme with the minimum degree of inter-well communication and the minimum coefficient of the Gini is selected as the injection-production scheme, so that the one-way effect caused by the channeling of the injected water along the high diversion channel is avoided, and the sweep coefficient of the injected water is improved.

Well P1, well P2, well P3, well W2 drilled into cavern type reservoirs, well W1 drilled into fracture type reservoirs. Well P1 daily oil production 27m3Water content 36%, daily oil production 42m of well P2328% water content, and 38m daily oil production of well P33And the water content is 35 percent, the well W1 is opened with high water content, and the well W2 produces 0.89t of oil in daily time and does not contain water. Two initial schemes are determined according to the principle comprehensive consideration, and respectively: w1 well waterflooding (initial scenario one) and W2 well waterflooding (initial scenario two).
