我国至今在世界上属于石油大国。自80年代以来,我国发现大部分油田开始,随着机械动力的扩展与开发,对石油的需求量也大幅度增加,研究剩余油分布,提高采收率已经成为世界各石油生产国普遍关注的问题,我国各大油田也不例外。大港油田疏松砂岩油藏较多,港西、马西、港东油田都占很大比例,因此搞好防砂工作非常重要。出砂对于油水井来说危害巨大,出砂出现会带来油田堵塞,严重甚至导致停产,加大工作量,成本增加,而且加大机器的磨损程度,最终导致油田亏空,油田坍塌的几率大大增加。所以油水井出砂治理的技术研究对港西油田来说十分重要。 My country is by far the largest oil power in the world. Since the 1980s, most of the oilfields have been discovered in our country. With the expansion and development of mechanical power, the demand for petroleum has also increased dramatically. Studying the distribution of remaining oil and increasing oil recovery has become a common concern in various oil producing countries in the world Problems, China’s major oil fields are no exception. Dagang oilfield loose sandstone reservoir more, Hong Kong West, Massey, Hong Kong East oil fields account for a large proportion, so do a good job of sand control is very important. Sand production is very harmful to oil and water wells. Sand production can cause blockages in the oilfield. Serious or even stop production. Increasing the workload and increasing the cost. Increasing the degree of wear and tear of the machine eventually leads to a shortage of oilfields. increase. Therefore, the technical research of oil and sand well management is very important to Hong Kong-West oilfield.
