Study On Feasibility Of Deep Flooding Of 4-7-14 Block

Shu 4-7-14 block is located in the west of the ditch sea railway,around the river around the area of Dujiatai.It is located in the middle part of the western slope of the western depression of the Liaohe fault basin,the southeastern part of the Shuguang area of the Shuguang Oilfield,and the east and the duguang ancient burial hill.The main development stratum is the upper part of the fourth section of the Shahejie Formation Oil layer.The distribution of oil layer is affected by tectonics and lithology,which is a lithologic tectonic reservoir.Shu-4-7-14 block long-term waterflooding development,reservoir heterogeneity intensified,in the current water injection mode,the water injection volume is difficult to further improve,it is difficult to significantly improve the recovery rate.In this paper,the experimental area is optimized on the basis of fine characterization of the block geological body,and it is of great significance to carry out the deep flood control experiment,which is of great significance to improve the recovery of ordinary heavy oil reservoir in Liaohe Oilfield.First of all,the paper puts forward the main research contents,the main achievements submitted,the achievements and achievements.The paper introduces the characteristics of the oil field,the study of reservoir address characteristics,the evaluation of waterflooding effect,the feasibility analysis,the design of reservoir engineering,the prediction of flood control and the economic evaluation,the dynamic detection scheme and the implementation requirements are described in detail.It is possible to improve the recovery rate of oil reservoirs and fully exploit the resources of oil exploitation,and take the correct research on the reservoirs,Mining methods,and then to achieve the purpose of the study.The method studied in this paper is suitable for the exploitation of complex environment in the old oil area of Liaohe Oilfield,which is of great significance and has important reference value for future exploitation of old block.
