完井工作包括多种工艺过程,且受诸多因素的影响和制约。完井方法正确与否会影响到一口井的产量和寿命,只有根据油气层的具体条件选用合适的完井方法,才能有效地保护产层,达到提高采收率的目的。完井方法的系统工程,是根据已有的广泛工程,地质等数据资料,确定完井井底结构选用标准。重点是建立和得出有关参数的数值指标,通过各方面的分析,以 Completion work includes a variety of processes, and are subject to many factors and constraints. Whether the completion method is correct or not will affect the output and life of a well. Only by selecting the appropriate completion method according to the specific conditions of the oil and gas well can the production layer be effectively protected to achieve the purpose of enhancing oil recovery. Completion method of the system engineering is based on the existing extensive engineering, geological data and other data to determine the completion of the bottom hole structure selection criteria. The key point is to establish and derive the numerical index of the relevant parameters, through various aspects of analysis
