Abstract


Oilfield Oilfield Surface water injection network is an important part of the pipe network and shoulder injected to the reservoir medium (water, polymers, etc.) the arduous task, and ground water injection network optimization to improve the production rate and recovery, to ensure the normal development of oilfield production plays an important role. Reasonable oilfield water injection network optimization can not only reduce the cost of construction of water injection system can also reduce its operating costs, so the oilfield water injection network optimization study is necessary. This article from the number of water injection system injection plant optimization, topology optimization of the parameters of the pipe network optimization three aspects of the water injection network optimization studies. In the oilfield surface pipe network optimization process obstacle is an objective reality, the existence of barriers to the pipe network layout, site selection, the number of stations and pipe network parameters and other factors are present affected. Without the existence of obstacles to be considered, it will reduce system optimization effect, so that optimal results are not consistent with the actual situation, so consider this factor barriers water injection network optimization process is particularly important. Based on this, the paper ground water injection network for the study, examining different obstacle avoidance optimization algorithm to determine the water injection network for obstacle avoidance algorithm, and after injection area is divided into several sub-regions, each sub-region are single station water supply mode, the sub-region based on cost and water distribution pipes relationship between cost, comprehensive and control of conventional pit radius constraints, the establishment of a mathematical model of the well group division. Affiliation preliminary determination of each well, using the entire oilfield water injection network system for the study, in order to inject a total investment cost of water supply network as the objective function to injection wells for the process parameters and geometry constraints established for water injection in the presence of obstacles Network topology optimization model and water injection network parameter optimization model, the model coupling avoidance optimization algorithm, namely avoidance determined after considering the location and layout of each station connection; connection determined parameters for water injection network optimization, determine the appropriate pipe network parameters; final study injection plant pipe network is not the same number of total costs to determine optimal number of injection points, and ultimately more filling stations under water injection pipe network optimization. In theory, based on the mathematical model using computer optimization software to solve the preparation, the use of C Builder prepared water injection network optimization software, and Jing'an Oilfield water injection network Panguliang Western optimization, for example, the results show that the optimization software ground for oilfield water injection network planning and design work has a certain significance.
