含蜡高凝原油在注水开发过程中,油井结蜡、水井结垢是一项常见的问题。尤其对于特低渗透油田,在生产中随着井筒温度的降低,蜡组分将逐渐析出,并聚集、粘附在油管壁上,直接影响自然产能本来就低的油井产量。同时,低孔隙度、低渗透率对注入水水质的敏感程度,更易造成结垢堵塞,使单井配注量难以满足。因此,油井采取防蜡措施、水井采取防垢措施,对于维持特低渗透油田的正常生产具有重要意义。 Waxy hypercoagulable crude oil In the development of waterflooding, well waxing and well scaling are a common problem. Especially for ultra-low permeability oilfields, as the wellbore temperature decreases during production, the wax components will gradually separate out and accumulate and adhere to the wall of the oil pipe, directly affecting the production of oil wells with low natural productivity. At the same time, the sensitivity of low porosity and low permeability to the quality of injected water is more likely to cause scale fouling and clogging, which makes it difficult to meet the requirements for single well injection volume. Therefore, the oil well to take anti-wax measures, wells to take anti-scaling measures for maintaining the normal production of ultra-low permeability oilfield is of great significance.
