为了录取油井含水资料,油井取油样成为采油工每天必须完成的工作,目前,使用常规的取样器取样的缺点是要先放空,到了冬季生产容易冻堵。放空造成一部分能量的损失,而对取样器进行解堵会有一定的安全隐患,造成环境污染,给采油工标准化井场的完善带来较大的困难,增加采油工的工作量。本文针对上述问题研制设计了免放空防冻堵取样器,旨在弥补目前常规取样器的不足,达到安全环保生产、减少采油工工作量的效果。 In order to recruit oil well data, oil well sampling has become a daily job that oil tankers must complete. At present, the downside of sampling using conventional samplers is that they should be vented first and then frozen in winter. Vent some of the loss of energy, while the sampler to unblock will have some potential safety problems, resulting in environmental pollution, oil well workers to improve the standardization of the well site to bring greater difficulties and increase the workload of oil production workers. In view of the above problems, this paper developed a vacuum-free anti-freeze blocking sampler designed to make up for the lack of conventional samplers, to achieve safe and environmentally friendly production, reducing the workload of oil producers.
