Problems solved by technology

However, the material support system of the deep-sea oil and gas exploration base involves a huge amount of parameters. Compared with some existing systems, the solution set increases exponentially, and so does the time complexity.
Using the existing algorithm, although the optimal solution can also be calculated, the calculation speed is too slow to meet the needs of deep sea oil and gas material support

Embodiment Construction

[0020] The present invention will be described in detail below in conjunction with the accompanying drawings. However, it should be understood that the accompanying drawings are provided only for better understanding of the present invention, and they should not be construed as limiting the present invention.

[0021] The simulated annealing algorithm starts from a relatively high initial temperature, and with the continuous decrease of the temperature parameter, combines the probability jump feature to randomly search for the global optimal solution of the objective function in the solution space, that is, the local optimal solution can jump out probabilistically. and eventually tends to the global optimum. If the greedy strategy is used to find the (global) optimal solution of the function, the test starts from point A. If the function value continues to decrease, the test process continues. When point B is reached, the search process ends, and a local optimal solution B is...

Abstract

The invention relates to a deep sea oil and gas field drilling and production development material transportation scheme selection method which is characterized by comprising the following steps: 1) obtaining parameter information of a deep sea oil and gas field drilling and production development material guarantee system; the method comprises the steps of (1) acquiring parameter information of aship, (2) presetting the requirement of a transportation scheme according to the acquired parameter information, and (3) selecting an optimal transportation scheme meeting the preset requirement in atransportation scheme solution space by adopting a simulated annealing algorithm, is extremely high in operability, can adapt to computer platforms with different computing power, and can be widely applied to the technical field of ocean oil and gas development.

Description

technical field [0001] The invention relates to a method for selecting a material transportation scheme for deep sea oil and gas field drilling and development, and belongs to the technical field of offshore oil and gas development. Background technique [0002] In the process of offshore oil and gas exploration and production, it is necessary to provide material support for offshore oil and gas exploration and production bases. Due to the particularity of the material support of offshore oil and gas exploration and production bases, it is necessary to establish a reasonable material support system, which not only meets the material supply of offshore oil and gas exploration and production bases, but also reasonably arranges the transportation of materials to reduce transportation costs. [0003] The existing material support system is an offshore material support system, which is relatively simple compared with the shore-based base-island reef base-floating base model of de...
