Study On ESP Working Condition Analysis Of Shallow Water Oil Field

With the development of land-based oil field into the mid-and late stage,offshore oil field particularly in shallow areas has been more and more developeted.Submersible pump by virtue of its small footprint,simple operation has been largely used in offshore field. Due to the special environment of offshore oil and gas production, safety and reliability has become the most important issue.In order to maximize the potential production ability of the submersible pump to ensure the safety of offshore oil and gas production and extention of the life cycle of submersible pump,analysis of working conditions, and to take appropriate measures to maintain submersible pump in good working condition has become especially important. Shallow water oil submersible pump operation analysis is a more complex technology, we must consider offshore oilfield tubular structure is different from the land and its particularity of production parameters, the results of the analysis of working conditions have been more in line with the actual situation.This article first submersible pump basic theory and analysis of the general theory of condition processes are discussed, the submersible pump oil into the production system is divided into systems, wellbore flow systems, downhole pump system, three sub-systems of the various sub-systems detailed study of selected offshore oil field production systems adapted to the computational model, especially for Shengli Oilfield special column structure of analysis, research in shallow water areas suitable for submersible pump unit production parameters new method to calculate - Casing parameter method, the pipeline parameter method. According to Shengli oil field reservoir parameters and production parameters of submersible pump submersible pump that affect working conditions of the main factors and the establishment of shallow water oil production systems, submersible pump condition analysis plates, the application compiled Visual Basic 6.0 the corresponding condition analysis software, able to condition analysis submersible pump wells and their production systems carry out the necessary transformation of production measures, to block oil capacity and oil pumps for the liquid fluid production capacity of the optimal match, submersible electric The optimal pump working state of shallow oil field development to achieve the security and reliability.
