摘要
现场录井之中,准确计算油气上窜速度对安全钻井、油气层的保护和后期的测试、油气产能评价等意义重大。根据油气上窜速度可以对储层的特性和产能进行定性评价、合理调整钻井液密度,既能保护油气层不被压死,又能使钻井工程安全的施工。为此,提出了一种计算油气上窜速度的方法,该方法同时考虑了井深结构和钻具结构等影响环空体积的因素。现场作业表明,该方法是可行的。
In oilfield well logging,accurately calculating oil and gas jumping speed is significant for safe drilling,reservoir protection and post-test assessment of oil and gas production.According to oil gas jumping speed,the reservoir characteristics and capacity to conduct qualitative evaluation are possible,in particular,to adjust drilling fluid density reasonable is both to protect reservoir from being crushed to vanish and enable the safety construction of drilling engineering.In this paper,a new method of calculating the jumping speed of oil and gas is present,it takes into account both the depth of the well structure and the drilling structure annulus size factor.This method works well in a foreign construction of some well and recognited and praised by foreign company.
