摘要:
由于水平井钻井技术的飞速发展，水平井–直井联合开发技术已经逐渐成熟，然而在设计油田开发方案和油藏工程计算时，对于压裂水平井–直井联合开发井网压裂水平井参数的优化还比较少。本文依据大庆某外围低渗透薄层水平井–直井联合开发油田的地质特征和开发特征，应用油藏数值模拟Eclipse软件并采用LGR局部加密网格技术建立了具有代表性的机理模型，从而对水平井–直井联合开发井网压裂水平井的参数进行优化，研究结果为类似水平井–直井联合开发油田压裂水平井参数优选提供了指导。
Due to the rapid development of horizontal well drilling technology, Horizontal well-Vertical well joint development technology is gradually mature, but in the oil field development plan design and the calculations of reservoir engineering, optimization of the fracture parameters of fractured horizontal well of Horizontal well-Vertical well joint development well pattern is relatively less. According to the geological characteristics and development characteristics of a peripheral low permeability thin layer Horizontal well-Vertical well joint development oil field in Daqing, and applying the reservoir numerical simulation software Eclipse with the LGR technology, the typical mechanism model is established. Then the fracture parameters of fractured horizontal well of Horizontal well-Vertical well joint development well pattern are optimized. The results can provide guidance for the optimization of the fracture parameters of fractured horizontal well in the similar oil fields of Horizontal well-Vertical well joint development.
