This paper analyzes the formation mechanism of reservoir bitumen in M oilfield, the harm to development of oil field, and predicts the distribution of reservoir bitumen. At the same time, this paper analyzes the situation of asphalt plugging in production wells, the mechanism and distribution of asphalt precipitation, studies and understands the plugging measures, and the successful experience of the implemented wells. The research and solution measures are provided for the bitumen/asphalt problems in similar oil fields.展开更多
