油水井出砂可能导致砂埋油层或井筒砂堵,造成油水井不能正常生产或停产等一系列不良后果,所以对油水井出砂的防治与研究从20世纪60年代就已经开始了。目前的防砂技术主要分为机械防砂、化学防砂和复合防砂3大类。砾石充填防砂技术作为一种有效的机械防砂手段,在新疆油田有广泛的应用,该工艺防砂效果的好坏与防砂筛管缝宽、充填砾石尺寸、砾石填充量、充填排量和充填压力等参数的设置有着密切的关系,因此防砂施工参数的优化显得尤为重要。
Oil and sand production may lead to sand buried oil or sand block sand block, resulting in oil and water wells can not be normal production or stop production and a series of adverse consequences, so the oil well sand prevention and research since the 1960s has already begun. The current sand control technology is divided into mechanical sand control, chemical sand control and composite sand control 3 categories. Gravel pack sand control technology as an effective means of mechanical sand control in Xinjiang Oilfield has a wide range of applications, the sand control effect of the process is good or bad and sand control screen slit width, filling gravel size, gravel packing, filling capacity and filling pressure The parameter setting is closely related, so the optimization of the sand control construction parameters is particularly important.
