| Abstract: | According to the different reservoir flow characteristics and fracture extension, this paper discusses theeffect of water selected control wells fracturing techniques. Respectively, from the use of selective control of waterproppant, water blocking fracturing fluid and manufacturing artificial isolation layer three processes on - site pilottest application effect analysis, it can analyze the processes controlling water and moisture content before and afteruse oil production situation. Combined with the engineering geological characteristics of different zones with highcontent of water wells, a optimization fracturing process selection is proposed. |
