钻井液屏蔽暂堵技术在陕北探区的应用试验

Application Experiment of Drilling Fluid Screening Temporary Blocking Technique in Northern Shanxi Exploration Region

针对陕北探区储层地质特性,认为实施钻井液屏蔽暂堵技术有利于保护储层,为此开展了有关应用试验研究。首先在室内进行了屏蔽暂堵剂和储层保护剂的筛选和性能试验,然后将选定的保护剂应用于富古4井的现场试验中,取到了保护储层的良好效果。

In consideration oi reservoir geologic properties in northern Shanxi exploration region.it is considered that implementation of drilling fluid screening temporary blocking technique is beneficial to reservoir protection. Therefore experimental study is performed on related application. Screening temporary blocking agent and reservoir protection agent selections and their performance testings are conducted first, and then the selected protection agent is used for field test in Well Fugu4 with good result of reservoir protection.
