Problems solved by technology

[0002] The current reservoir numerical simulation technology mainly focuses on development indicators such as reservoir pressure, production rate, and oil-water production. It lacks the constraints of oil production engineering data, and the results of reservoir numerical simulation deviate from the actual situation. For example, the simulated reservoir local pressure, unit Inaccurate well production index, etc.; in reservoir plan formulation or production adjustment numerical simulation research, oil production engineering parameters and surface system data are not applied, resulting in inconsistency between the planned production of the reservoir plan and the production capacity of the pumping unit and pipeline network system

Embodiment 1

[0075] Example 1: Taking a new development block of an oil production plant as an example, according to the above steps, the integrated simulation study of the oil reservoir and the wellbore pipe network was carried out, and the oil reservoir model, the wellbore model and the pipe network model were established respectively. At the production time point of March 20, 2018, an integrated simulation calculation and production analysis were carried out.

[0076] Using the integrated coupling model, the production changes can be accurately predicted, and adjustment measures and directions are proposed.

[0077] The characteristics of the calculation results of the wellbore model, the reservoir model and the integrated coupling model are as follows:

[0079]

[0080] The integrated simulation results are compared with the numerical simulation results of the single-reservoir model, and it is found that the two have significantly different production trends. The convent...

Embodiment 2

[0084] Example 2: The simulation shows that the pressure along the pipeline network in the northern part of a certain area is relatively high and the gathering and transportation energy is sufficient, while the pressure along the southern route is generally low. It is necessary to select suitable sites and deploy booster pumps to improve the gathering and transportation capacity. According to the simulation suggestion, 2 booster pumps were newly deployed in the southern part of the pipeline network to make the gathering and transportation production run smoothly.

[0085] The analysis results guide the establishment of the surface pipe network model in the well area, which can accurately predict the pressure and temperature along the way, and realize the upgrade from the information pipe network to the intelligent pipe network.
