Water Control Technology For Xi Jiang23-1Oil Field

In basal ground water reservoir, reservoir’s physical propertyisnice, oil layer is thin, basal ground water is easy to break, the coning water is faster, in order to delay the basal ground water coning rate, prolong the well anhydrous and low water period of production, improve the recovery ratio, Xijiang23-1oilfield well drilling and completion project team and reservoir engineer have done a lot of research work, in the oilfield was first introduced into the balancer machine water control device in the production zone, with consideration of geological material inequality, locus of control quality, borehole enlargement and other related factors, and flow pressure loss calculation, rational use of oil/water expandable packers of the wellbore is divided into several independent production area, in easy water breakthrough cone into the region, through the adjustment of the period of formation fluid inflow nozzle, control the production pressure difference, thus adjusting the regional effective output, so that the entire production period of bottom water coning synchronous lifting, delay, to control the purpose of water.
