Embodiment Construction
[0073] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0074] The embodiment of the present invention provides a method for synergistic combination of development strategies in the whole life cycle of continental layered sandstone reservoirs, figure 1 It is a flow chart of a collaborative combination method for the full life cycle development strategy of a continental layered sandstone reservoir provided in this embodiment. The collaborative combination method for the full life cycle development strategy of a continental layered sandstone reservoir includes:
[0075] S1: Analyze the development history of the target reservoir, and judge whether there is any inconsistency in the development strategy combination of the previous development stage of the target reservoir. The development strate...

The invention discloses a method for synergistic combination of development strategies in the whole life cycle of continental layered sandstone reservoirs, which belongs to the technical field of reservoir development. The method includes analyzing the development history of the target reservoir, and judging whether there is a dissonance in the development strategy combination of the previous development stage of the target reservoir; when there is a dissonance in the development strategy combination of the previous development stage, For the non-coordinated development strategy in the development strategy combination corresponding to the previous development stage, the next development strategy of the non-coordinated development strategy is selected according to the chronological sequence of various development strategies as the development strategy combination of the current development stage; according to the current development strategy The combination of development strategies in the first stage is used to develop the target reservoir, avoiding the development strategy only for a single aspect with contradictions in the development process of continental layered sandstone reservoirs, while ignoring the secondary contradictions, resulting in the development effect cannot be effectively achieved. improved situation.
Description
technical field [0001] The invention belongs to the technical field of oil reservoir development, and in particular relates to a method for synergistic combination of development strategies in the whole life cycle of continental layered sandstone oil reservoirs. Background technique [0002] Continental layered sandstone reservoirs have the characteristics of many oil layers, strong heterogeneity, low water flooding efficiency, and low natural energy. These characteristics make the reservoir development process confronted with diverse contradictions. At present, in the development process of continental layered sandstone reservoirs, development strategies are often formulated for a single aspect with contradictions, while secondary contradictions are ignored, resulting in that the development effect cannot be effectively improved. Contents of the invention [0003] In order to solve the problems existing in the prior art, the embodiment of the present invention provides a ...
