Embodiment 1

[0053] According to the project screening Ed>N (the N value selects different empirical values ​​according to different regions, different oil fields and reservoir types, N is generally not less than 1) to determine the optimal value of investment scale and the corresponding investment portfolio, including the after-tax internal rate of return, The net present value after tax is the result of economic evaluation.

[0054]The first step is preliminary screening. Eliminate projects with after-tax net present value less than 0 and after-tax internal rate of return less than the benchmark rate of return (usually 8%) set by the enterprise. The purpose of this step is to ensure that a single block meets the most basic benefit requirements of the enterprise.

[0055] The second step is to sort the items. According to the characteristics of production capacity construction projects focusing on benefit scale, the projects are sorted in descending order of net present value, and inves...

Embodiment 2

[0064] Take the crude oil development project investment table of a branch company in 2018 as an example, including a total of 123 block projects in the new area and the old area. For this oilfield, N is 1 as the selection basis for the net present value investment elasticity coefficient of this example.

[0065] (1) Eliminate block projects with after-tax net present value less than 0. A total of 92 projects have NPV>0, and the cumulative investment is 2,862.4 million yuan. The calculation results of net present value and internal rate of return refer to the oil price of US$50 / barrel. The details are shown in Table 1.

Embodiment 3

[0086] like figure 2 shown, an optimization device for an oilfield development project portfolio comprising:

[0087] Screening module for screening development projects that meet the set conditions among multiple oilfield development projects;

[0088] The sorting module is used to sort the development projects that meet the set conditions according to the net present value of the project;

[0089] A calculation module for separately calculating the investment elasticity of the net present value of each development project in the development projects that meet the set conditions;

[0090] The comparison module is used for sequentially comparing the investment elasticity of the development projects with the set threshold according to the sorting result, and selecting the development projects corresponding to the investment elasticity greater than the set threshold for combined development.

[0091] Optionally, the set threshold is not less than 1.

Abstract

The embodiment of the invention discloses an optimization method and device for an oilfield development project portfolio and electronic equipment. The optimization method for the oilfield development project investment portfolio comprises the following steps: screening development projects meeting set conditions from a plurality of oilfield development projects; sorting the development projects meeting the set conditions according to the project net present values; respectively calculating the investment elasticity of the net present value of each development project in the development projects meeting the set conditions; sequentially comparing the investment elasticity of the development projects with a set threshold value according to a sorting result, and selecting the development projects corresponding to the investment elasticity greater than the set threshold value for combined development. The purpose of giving consideration to the overall benefits and resource utilization rates of the single project and the project combination is achieved.

Description

technical field [0001] The invention belongs to the technical field of oilfield development, and more particularly relates to an optimization method, device and electronic equipment for an oilfield development project investment portfolio. Background technique [0002] Oilfield development projects include capacity construction projects in new and old areas, and are the main targets for annual oilfield development deployments. [0003] Regarding the determination of the project investment scale, the current practice is to screen projects whose internal rate of return is greater than or equal to the benchmark rate of return set by the enterprise, and the investment of these projects is summed up as the investment scale. The investment scale obtained by this method can only be said to be the maximum investment scale, which can only ensure the benefit of a single project, and cannot judge whether the investment benefit under this investment scale is optimized. [0004] In the ...
