摘要
塔北地区多数油气井在修井过程中发生修井液漏失,而且修井后油气产量并未显著提高。本文依据该区油气层特征及漏失特点,分析了修井液漏失的原因,并通过室内系统实验,研制出了一套修井防漏浆液配方且对其进行经济评价,为有效地解决该区修井过程中修井液漏失的问题奠定了基础。
Loss of workover fluid broke out in most of oil & gas well in Tabei district.
Furthermore oil & gas production aren't remarkably increased after workover treatment.
According to characteristics of oil & gas reservoir and loss of circulation,this paper analysed
the reason of loss. By means of systematically laboratory experiments,a serious formula of
loss protection fluid was developed for workover. It provides a basis for effectively solving the
loss of workover fluid problems for workover jobs.
