近年来,随着经济的不断发展,我国油田开采工作也取得了巨大的效益。在油田开采过程中,井口回压问题是影响油井产量的一个重要因素,其对于油井产量以及抽油机的耗电量都会产生严重的影响。目前国内大多井口回压都控制在1-1.8Mpa左右。油井井口回压的问题是客观而且普遍存在的,只有对其进行有效的处理,才能够保证油井的正常工作。本文就主要针对井口回压对油井产量以及抽油机耗电量的影响进行简单的分析。
In recent years, with the constant development of economy, great achievements have also been made in oilfield exploitation in our country. Wellhead back pressure is an important factor affecting oil well production during oilfield production, which can have a serious impact on well production and pumping unit power consumption. At present, most wellhead back pressure is controlled at about 1-1.8Mpa. Wellhead back pressure problem is objective and ubiquitous, and only effective treatment of it can ensure the normal operation of the well. In this paper, a simple analysis of the impact of wellhead back pressure on well production and power consumption of pumping units is made.
