因开发后期调整需要及地面条件限制,八面河油田水平井,特别是稠油区块水平井逐年增多,但水平井泵效总体较低,仅为51.5%,其中稠油区块平均泵效仅为39%,水平结构的增液优势并未发挥。造成这种现象的主要原因一是油藏条件上区块供液能力总体较差,二是工程上地层供给能力与生产参数的矛盾。稠油水平泵便是为了应对上述问题,旨在从举升角度出发以提高区块油井泵效的有益举措。
Due to late adjustment needs and ground conditions, the horizontal wells in the Bamianhe oil field, especially horizontal wells in the heavy oil fields, have been increasing year by year. However, the horizontal well has a relatively low pumping efficiency of only 51.5%, of which the average pumping efficiency in heavy oil blocks is only 39 %, The advantages of the horizontal structure of the liquid did not play. One of the main causes of this phenomenon is that the reservoir liquid supply capacity of the block is generally poor, and the second is the contradiction between the supply capacity of strata and the production parameters in the project. Heavy oil level pump is to deal with the above problems, designed to lift from the point of view to improve the efficiency of pumping well block measures.
