A Study On Low Fluctuation Pump By Using Hydraulic Filter

With the deepening of reservoir development and the increasing of the difficult of thedevelopment, investment and costs are increasing. Although the overall production of theTangshan oil District is relatively stable, there have been many production contradictions. suchas high water content, production decline rapidly, well effect slowly, Well not perfect, and soon.To improve the level of oil reserves of spending, slow the current production of thecontradictions arising in the process, to ensure the future stability of oil production continuedto increase. This research studied the geological and reservoir characteristics of the re-Fanreservoir oil zone, stamp a three-dimensional fine geological model. The status of reservoirdevelopment and production characteristics were analyzed. This research identify the maincontradiction and development the reservoir through reservoir simulation.programs are toachieve the objective of improving development effectiveness.This paper carried out the study area of reservoir simulation, history matching and miningin the amount of fluid reserves to achieve complete basic fitting, oil production rate andmoisture content of90%or more fitting well. History matching results agree relatively high,indicating that the construction of underground geological model can reflect the actualsituation with the oilfield development model used in the actual production line andunderground conditions. Based on coarsening the geological model, numerical simulationusing Eclipse software research numerical simulation based on establish the three-dimensionalgeological model, history matching of geological reserves and liquid production capacity isalmost reached full fitting, matching is perfect.
