Jing An Oilfield Da Lu Gou San Qu Control Water Stable Oil Technical Countermeasures

With the development of oil fields extend continuously, reservoir water continued to rise, increasing production situation, how to realize the long-term stability of the reservoir, to maximize the benefits of input and output, there is an urgent need to study oil reservoir in high water cut stage of stabilizing oil production by water control technology policy.This paper studies da lu gou san qu has entered the high water cut development period, because the reservoir plane contradiction, Rapid increase of water cut, The single well production decline, The development effect of gradual variation. The water control and stable oil technology research work, study on reservoir characteristics, oil migration, the rise of water law, formulate reasonable development of technology policy, improve the technology of recovery, comprehensive management of the next step plan stable reservoir, control the water rise, improve the whole block development effect. At the same time can provide guidance for the development of similar reservoirs.This paper makes full use of the fine reservoir description results existing, combining all kinds of chemical analysis data, the lithology, electrical property, physical property, oil-bearing property of reservoir macroscopic, microscopic characteristics; core data evaluation of water using field data, flooding situation, from the macroscopic(well, reservoir) and micro(core test Study on flow characteristics) two aspects, development characteristics and rules; considering the reservoir micro structure, sedimentary microfacies, reservoir properties, fluid properties, dynamic monitoring data, division of flow units in block; then using reservoir engineering, dynamic analysis, research and technological development policy of water cut development period in; carry out the rule of remaining oil distribution, the classification of the current pattern of remaining oil enrichment zone. In the end, the comprehensive adjustment measures are formulated, which is the main content of acid, water shutoff, profile control, increasing the amount of fluid, blocking water and minus punch.
