油田的开发经历了较长时间,许多条件出现变化,需要利用水平井进行石油的开采。水平井相对于一般直井结构更加复杂,且在技术及认识上尚未形成统一的标准,进行实际建设工程时,会受到各种不确定因素的影响,存在一定的难点。本文简单分析了影响水平井产能的各项因素,阐述了水平井最优竖向位置及水平井段最优长度等,为从事水平井开发的人员提供一定的参考与借鉴。
Oilfield development has lasted for a long time, many conditions change, the need to use horizontal wells for oil exploration. Horizontal wells are more complex than normal vertical well structures and have not formed a uniform standard in technology and understanding. When actual construction projects are carried out, they will be affected by various uncertainties and have certain difficulties. In this paper, the factors that affect the productivity of horizontal wells are briefly analyzed, the optimal vertical position of horizontal wells and the optimal length of horizontal wells are expounded, which will provide reference for the personnel engaged in the development of horizontal wells.
