油田开采生产过程中,高油气比井的冻堵与积液问题一直是油田开采中影响开采生产效率的重要问题。井下油嘴是解决油田开采中试气试油冻堵与积液问题的有效方法与措施。本文将结合油气开采中试油试气冻堵实例,在对于油气开采中试气冻堵原因分析的情况下,通过对比对于井下油嘴解决试气冻堵原理、优势等进行分析论述。 During the process of oilfield mining and production, the problem of freezing blockage and fluid accumulation in high-oil-gas ratio wells has always been an important issue affecting the production efficiency in oilfield mining. The downhole nozzle is an effective method and measure to solve the problem of freezing, blocking and accumulating fluid during the trial gas test in oilfield. In this paper, we will combine the example of freeze-block test of oil-in-gas in trial production, and analyze the principle and advantages of freeze-block test of downhole oil nozzle by comparing the reasons of freeze-block test in oil and gas exploration.
