为了解决传统热洗工艺对地层造成的伤害或压死井问题,应用高效油层防污染管柱进行热洗,改进了传统热洗工艺,通过对这种热洗效果的分析,克服了传统热洗工艺的不足,避免了洗井液对油层的污染,同时也节约了洗井液用量、以及缩短了含水恢复期,该工艺技术具有良好的社会效益和经济效益。
In order to solve the problem that the traditional hot-cleaning process causes damage to the formation or to kill the well, the hot-cleaning with the highly effective oil-field anti-pollution column is adopted to improve the traditional hot-cleaning process. By analyzing the hot-cleaning effect, The lack of technology, to avoid the flushing fluid on the reservoir contamination, but also saves the amount of flushing fluid, as well as shorten the water recovery period, the technology has good social and economic benefits.
