庄平3井低固相低伤害完井液体系研究与试验

Research and Experimentation of Low Solid-Phase and Low Damage Completion Fluid Systems of Well Zhuang-Ping No.3

针对西峰油田特低渗透油层，通过对储层的物性特征、储层敏感性矿物、地层水性质的分析研究和室内敏感性评价实验，初步搞清了钻井完井液对特低渗透储层的伤害机理，确定了完井液施工措施，并研制出一种新型的水平井低伤害完井液体系，在庄平3井进行了试验，应用效果良好。

Aiming at low-permeability reservoirs of Xifeng Oilfield, through analysis of reservoir properties, reservoir sensitivity minerals, formation water property and evaluation of the indoor sensitivity experiments, the damage mechanism of drilling and completion fluid to extra-low permeability reservoirs is initially understood. Construction measures of completion fluid are determined, and a new type of low-damage completion fluid system for horizontal wells is developed. It was tested on well Zhuang-Ping #3 and the results were very good.
