of the impact of fiber content on the performance, plugging and water loss, such as weaknesses in performance make a tests conducted studies. paper chose the ceramic fiber and polypropylene fiber put into the oil well cement posites together as well as one by one, including rheology, flexural strength performance, loss of performance for optimization and research. Experiments e to the conclusion: When ceramic fiber and polypropylene fiber content of %, its rheological properties did not deteriorate, and bending around a 40% increase in performance, pression performance of more than 30% , this is the most valuable effect; Fiber cement’s slurry water content has the best rate of increase in the volume of existence。 通過對(duì)陶瓷纖維、聚丙烯纖維改性水泥漿(石) 抗折抗壓、流變流動(dòng)、失水和堵漏 的實(shí)驗(yàn)測(cè)試,得出 了 : 當(dāng)陶瓷纖維與聚丙烯纖維摻量在 %左右時(shí),其抗折抗壓性能分別提升 40%和 30%以上達(dá)到最優(yōu)值;纖維的摻量對(duì)于水泥漿失水率存在最佳加量;堵漏效果與纖維摻 量 在一定上限下 成正比; 水泥石提前收縮 ;復(fù)合改性缺陷 等結(jié)果。 本科畢業(yè)設(shè)計(jì)(論文) 題目 復(fù)合纖維改性水泥漿及性能探討 摘要 目前國(guó)內(nèi)外油田開采環(huán)境、技術(shù)越來越復(fù)雜,對(duì)固井水泥漿(石)的性能要求也越來越高 。本文針對(duì)近年來對(duì)纖維改性水泥漿體系研究中 纖維 摻量 對(duì)性能影響規(guī)律、堵漏及失水性能測(cè)試等薄弱環(huán)節(jié)進(jìn)行了探討研究。 由于其優(yōu)異的改性性能, 陶瓷、聚丙烯 纖維水泥漿體系在固井工程有廣闊的應(yīng)用前景。 plugging effect of fiber content and the next is proportional to a certain limit。 plex defects, such as the result of modification. Modified due to its excellent performance, ceramicpolypropylene fiber slurry system works in the cementing broad application prospects.
