若压裂油层附近存在水层,传统缝高控制措施为通过变排量或降低施工规模等,规避施工中水淹事故的发生及阻止裂缝沟通水层。该处理措施存在如下局限性,即水层与油层间距缩短至一定范围,缝高控制措施将无法发挥其应有的作用。所以,将新型透油阻水支撑剂用于控制水层压穿后油井出水程度,研究结果表明,该技术有助于压后控水增油目标的实现。
If there is water layer near the fracturing reservoir, the traditional control measures for seam height are to avoid the occurrence of flooding accidents and prevent the cracks from communicating with the water layer by changing the displacement or reducing the construction scale. The treatment has the following limitations, that is, the interval between the water layer and the oil layer is shortened to a certain range, and the seam height control measure will not be able to play its due role. Therefore, the new type of oil-permeable and water-blocking proppant is used to control the oil well water discharge after the water is forced through. The results show that this technology is helpful to achieve the goal of pressure-controlled water-oiling.
