Logging Interpretation On The Water-flooded Zones

Flooded layer is the consequent of flood development, the recover of reservoir turns into oil and water, it is the inevitable product of oil field development, water flooded layer can be divided into flooding and side, bottom water flooding.At present, most of the production area of Liaohe oilfield has entered the afternoon of development life, composite water cut rose rapidly, flooding well logging becomed particularly important. Because of the complex reservoir feature, the alternation of injection water salinity, the law of water flooded is very complex, and the logging project was not complete, flood level logging data was not effective, which give great difficulty to well logging interpretation of water flooded layers.The project under the Liaohe oil field flooded well logging status of drawing on existing flooding well logging series and method of well logging in the Liaohe oilfield and the application of adaptive line analysis of the effects of flooding, summarized the main reason of low compliance rate in waterflood interpretation.According to the status of liaohe oilfield, and research the water flooded layer logging series and method at home and abroad, analyzed the adaptability and application effect of The logging series inliaohe oilfield, summarizes the main reasons of the low accuracy logging interpretation. Based on the experimental studies of water flooding mechanism, established the interpretation model. According to water flooded layer on the logging interpretation evaluation effect and the successful experience of other oilfield explain for liaohe oilfield, optimum out geological characteristics under the condition of the water flooded layer logging series,and study the interpretation of Watered-out Formation of some area, Effectively improve the accuracy of adjustment Wells, and achieved the purposes of improve the harvest .
