Deep Water Flooding Optimization Of Xinli Ⅲ Block Hypotonic Reservoir With Moderate Temperature

Hypotonic reservoir in Jilin Oilfield is potential, and most have entered the stage of high moisture content 。 The water cycle invalid, and development of Jilin Oilfield is Contradictory,to solving these problems Jilin Oilfield Company share strong support 。First completing water flooding, scend improving water flooding and last changing mode conversion,which is called "three-step " work arrangements. Improving water flooding is a priority at this stage, and deep profile control technology is the key- directional engineering,therefore, carrying out the main block flooding test new technology in the earliest development of new oil legislation has important practical significance. By screening a reasonable injectant system(using nanometer to micrometer size range of microspheres system),with increasing oil Pharmacy, which could not only further expand the water swept volume and improve the efficiency of wash oil, but also further address the deep reservoir heterogeneity of flooding problem, and ultimately achieve the the goals of econdary development of a more substantial increase waterflood oil recovery and improve waterflood development effect. This paper first aims at the forms and problems of oilfield development,second confirms basis of chosen of trial plot,then selects the plots and water injection well,last make sure of the injection in each layer.After all these things have been done,we should first determine the blank water flooding scheme,second set up system of optimization and optimal.Through the experimental results,flooding will be a great success。This new legislation will explore technology and methods not only for further secondary development of oilfield, but also for the Jilin Oilfield to explore the potential in high moisture from.
