Abstract

Development Zone has entered the stage of double-extra-high development, the ratio of water driving zones is increasing year by year, the inefficient and ineffective circulation is becoming more serious, the remaining oil is scattered heightly, and the object of modification becomes worse and the water cut rises rapidly. It is much more difficult to select wells and layers by using conventional fracturing technology and repeated fracturing of old wells, and the effect of increasing oil production is obviously reduced. To analyze the influence of production condition on fracturing effect, to study the formation of precision control fracturing technology, and to improve the effect of water driving measures in ultra-high water cut stage.
