摘要
水平井技术主要是因射孔井段在油藏中平行于油藏顶底界面延伸,增大了与油藏的接触面,降低生产压差,提高生产井产能。特别是底水油藏由于经长时间开采后,油水关系较为复杂,油水界面存在波状起伏现象,水平井技术是开发底水油藏的有效技术手段。为了充分发挥水平井的优越性,对确定水平井水平段位置及方向、水平段长度等参数进行优化研究,为经济有效动用同类油藏具有指导意义。
the horizontal well technology is mainly due to perforation interval in reservoir in parallel to the reservoir top and bottom interface extension, the contact surface with the reservoir increases, reduce the production pressure difference, improve the production wells. Especially the bottom water reservoir because of the long time after mining, oil--water relationship is complex, undulating phenomenon exists in oil--water interface, horizontal well technology is an effective technology development of bottom water drive reservoir. In order to give play to advantages of horizontal wells, and the optimization of parameters to determine the position and direction, horizontal section length of horizontal section, has guiding significance for economic effective development of similar reservoirs.
