我国油藏分布广泛,石油开采工业经历长时间的发展,开发技术也有了长足的进步。但是许多油田的性质有较大的区别,需要应用的技术也不一样。低渗透的油田具有较多的特殊性,在油藏的开发上存在较多困难。水平井技术以其采收率高、效率高、成本低等诸多优势在低渗透油藏的开发中占有较为重要的位置。本文结合某油田的情况,简单阐述了水平井的优化设计,包括垂直向位置优化、水平向长度设定、单井的产能优化等,为从事低渗透油藏开发事业的人员提供一定技术参考与借鉴。 China has a wide range of oil reservoirs, the petroleum exploitation industry has experienced a long period of development, and the development of technologies has also made great strides. However, the nature of many oilfields is quite different and the technologies that need to be applied are different. Low-permeability oilfields are more specific and have more difficulties in reservoir development. Horizontal well technology occupies a more important position in the development of low permeability reservoirs because of its advantages of high recovery rate, high efficiency and low cost. Based on the situation of a certain oilfield, this paper briefly describes the optimization design of horizontal wells, including the vertical position optimization, horizontal length setting and single well productivity optimization, which will provide some technical reference for personnel engaged in the development of low permeability reservoirs.
