低渗透气藏水平井割缝衬管完井设计

Well Completion Design of Slotted Liner for Horizontal Well in Low-permeability Gas Reservoir

水平井割缝衬管完井产能与衬管参数密切相关,衬管割缝参数越优化,产能比越高,气井获得井底完善程度越高,产能也越大。以某低渗透水平井割缝衬管完井后需要酸化解堵为例,借助数值模拟来优化该井完井设计,达到均匀布酸解堵,恢复气井的自然产能,达到提高气井产能的目的。

There is a close relationship between completion productivity of slotted liner for Horizontal well and liner parameters. If liner parameters are optimized, the index of the performance will be higher, the completion will be higher, and the productivity will be bigger. Taking a low permeability horizontal well completed with slotted liner which needed to acidizing plugging removal as an example, it takes use of numerical simulation to optimize completion design for the purpose of acid uniform placement, recovering natural productivity, and elevating oil well productivity.
