In this embodiment, in the process that the device in the library is operating, the information processing apparatus may acquire the first operating state of the device in the library of the oil and gas gathering and transportation unit at the current moment. The first operation state is a state of equipment in the oil-gas gathering and transportation combination station warehouse at the current moment, such as a liquid level of a water tank in the oil-gas gathering and transportation combination station warehouse, a switching state of a valve in the oil-gas gathering and transportation combination station warehouse, and the like.
Before the first operation state of the equipment in the oil-gas gathering and transportation combined station library is obtained, a simulation system of the oil-gas gathering and transportation combined station library can be further constructed, and the simulation system comprises a physical model corresponding to the equipment in the oil-gas gathering and transportation combined station library, and the following specific description is given: first, determining a plurality of devices in a library of oil and gas gathering and transportation combined stations and static parameters of the plurality of devices, wherein the static parameters are used for representing inherent properties of the plurality of devices, and the plurality of devices can comprise but are not limited to the following: three-phase separator, settling tank, walnut shell filter, fiber ball filter, etc. The above-mentioned static parameters represent inherent properties of the plurality of devices themselves, and taking a three-phase separator as an example, the static parameters of the three-phase separator may include, but are not limited to, the following: equivalent length of the three-phase separator, radius of the three-phase separator, total volume in a three-phase separator tank, cross-sectional area of a water chamber of the three-phase separator, cross-sectional area of an oil chamber of the three-phase separator, height of an oil spilling baffle of the three-phase separator, water density, oil density, gas average molecular mass, gas constant, gravity acceleration and the like.
Second, a physical model of each of the plurality of devices is constructed based on the static parameters of the plurality of devices. That is, parameters in the physical model of each device may be randomly initialized according to information of each device in the plurality of devices, and a secondary loss function between predicted data and actual production data at each moment is calculated according to historical operation parameters of each device, and the parameters in each device are estimated using a random gradient descent algorithm.
And determining the connection relation between each device in the plurality of devices of the oil and gas gathering and transportation combined station library. For example, the connection mode of the physical models of the plurality of devices can be determined according to the connection mode between the devices in the oil gas gathering and transportation combination station library. Specifically, each of the plurality of devices may be used as a node, and the node corresponding to each of the plurality of devices may be connected in an edge manner according to the connection manner between the devices in the oil and gas gathering and transportation joint station library.

And 8, repeatedly executing the steps 2 to 7 until a preset iteration termination condition is met.
In this embodiment, after each iteration, whether the number of iterations reaches a preset value may be determined, if yes, it is determined that a preset iteration termination condition is satisfied; or judging whether the parameter value of the first parameter of the first module and/or the parameter value of the second parameter of the second module are converged, if yes, determining that the preset iteration termination condition is met.
It should be noted that after the multiple iterations are performed, after the multiple four-point groups are obtained, the parameter value of the second parameter of the second module is updated by minimizing the quadratic time sequence differential loss function, and meanwhile, the parameter value of the first parameter of the first module is updated by the strategy gradient descent, based on the multiple four-point groups (for example, 3 or 4, which may be specifically set according to the actual situation).
It should be noted that, the first parameter is a parameter of a state determining action in the first module, and the second parameter is a parameter of a state determining value in the second module.
And 9, determining the target network when the iteration is ended as a preset action model.
It should be noted that, in the actual operation process, after the device in the oil gas gathering and transportation joint station library is operated based on the target action, the parameter value of the preset action model may be updated, which specifically includes the following steps: adding the target action to a random process to determine a third action; determining a fourth operating state based on the third action and the simulation system; determining a reward value of a fourth operating state, wherein the reward value of the fourth operating state indicates whether the simulation system operates normally when in the fourth operating state; and updating the parameter values of the preset action model through the first running state, the third action, the fourth running state and the rewarding value of the fourth running state. The parameter values in the updated preset motion model may be described in the above steps 2 to 7, and detailed descriptions thereof are omitted herein.
In summary, it can be seen that, in the training process of the preset action model, the parameter value of the first parameter of the first module and the parameter value of the second parameter of the second module are continuously updated through iteration, and the parameter value of the first parameter of the third module and the parameter value of the second parameter of the fourth module are continuously updated through the first module after updating the parameter value and the second module after updating the parameter value in an incremental updating manner, so that the trained preset action model is more fit to the state of each device in the oil-gas collection-transmission joint station library and the operation corresponding to the state, and meanwhile, due to the addition of a random process in the training process, the preset action model can find an optimal decision scheme to help the oil-gas collection-transmission joint station library optimize the production decision when the device in the oil-gas collection-transmission joint station library has a new state.
