With a view to the problems such as large solubility in oil and poor inhibition function of currently used corrosion inhibitors in oil fields, a novel water-soluble corrosion inhibitor ZYC-1 was developed based on a series of optimization tests concerning emulsification behavior, water-solubility, and corrosion-inhibiting effect. The corrosion-inhibition action of the newly developed corrosion inhibitor ZYC-1 was investigated using sealed stirring method in an evenly mixed water-oil fluid. It was found that ZYC-1 introduced into the wells and oil pipes as the water-soluble corrosion inhibitor was capable of greatly decreasing the total amount of Fe ions and the corrosion rate as well, which could make it feasible to put ZYC-1 into broader field applications.

在气举采油中,传统的套压控制气举阀的开启和关闭主要取决于注气压力(套压),往往造成低产井举空和高压气体"打循环";而高产井则出现阀间干扰,造成多点注气,耗气量大,且举升深度受到限制.新研制的ZBY-1型油压控制气举阀的注气量由井筒流压自动控制.流压升高,阀打开,注气量增加;流压降低,注气量减少,使气举井在恒定的流压梯度下工作,确保产量稳定.现场应用新型气举阀15井次,单井平均日产油量增加12.44t,平均举升深度增加750m,平均日注气量下降279m3,最大下入深度2920m,单井最高日产液量82m3,收到了较好的增产节气效果.
