油井防蜡降粘装置在现场应用认识 总被引:1,自引:0,他引:1
由于三矿地处过渡带,原油粘度高,含蜡浓度大,油井易结蜡,影响抽油泵正常工作,洗井效果不是特别理想。本文通过对常规热洗清蜡方式在现场应用技术上存在的弊端进行了分析,并针对过渡带油井结蜡严重,热洗周期短,洗井不彻底的问题,在井口安装了油井防蜡降粘装置试验应用,介绍了该装置的技术原理、仪器结构,对现场使用情况进行了效果分析,并对使用过程中出现的问题进行改进,有效地延长了热洗周期,取得了较好的试验效果。 相似文献

The toxicological end-points used in a method for the assessment of the toxicity of combustion products are described. The evaluation considers three areas of toxicological interaction: incapacitation, death, and post-exposure involvement. The model of incapacitation described is the leg-flexion avoidance response of the rat. Additional end-points to assist in the determination of the causality of the observed toxicity are included. The effects of the combustion products of Douglas fir, a phenolic foam, a urea formaldehyde foam and a flexible polyurethane foam on these endpoint are described. The wide range of types of potential toxicities resulting form exposure of animals to the combustion products of materials is discussed. Additionally discussed are the relative merits of the leg-flexion avoidance response as a model of incapacitation. Conclusions as to the important components of a first-tier toxicological evaluation of combustion products are drawn. 相似文献

The mechanism and rate of the melt extraction of eutectic-forming impurities from granules of organic substances are considered. A diffusion model is suggested for this process, and kinetic relationships taking into account the relative closed porosity are derived for calculating the purification efficiency for granules of various shapes and sizes. The solutions obtained are compared with equations known from the theory of countercurrent crystallization and other mass-transfer processes. Experimental purification efficiency data are presented for washing caprolactam granules in a tank apparatus and a countercurrent column. These data are consistent with the suggested washing model. The possibility of the intensification of mass transfer by promoting recrystallization in the granules–melt system by ultrasonic treatment and thermal cycling is analyzed. 相似文献

A variant of statistical processing of the data available in the literature is proposed with the aim of determining the most probable concentration dependences of the properties of binary glasses. The experimental data are processed using the SciGlass information system. Specific examples illustrating the application of the proposed method are given. The general potentialities of using the most probable concentration dependences of the properties of binary glasses both in research practice and in preparing and reviewing the papers containing new experimental data are analyzed. 相似文献
