【摘要】：在油田開發(fā)高含水階段實(shí)施瀝青顆粒調(diào)剖,既可調(diào)整層間矛盾、擴(kuò)大波及體積,也可以提高驅(qū)油效率,現(xiàn)場試驗(yàn)取得了一定的效果。但是,在試驗(yàn)中發(fā)現(xiàn)不同井層效果差別很大,效果不穩(wěn)定,原因不清。因此有必要通過室內(nèi)實(shí)驗(yàn),開展瀝青顆粒調(diào)剖適應(yīng)性及參數(shù)優(yōu)化研究。本論文在調(diào)研相關(guān)文獻(xiàn)基礎(chǔ)上,闡述了瀝青調(diào)剖機(jī)理,通過檢測粒徑分布、懸浮率、粘結(jié)溫度等參數(shù),對(duì)現(xiàn)場提供的瀝青顆粒進(jìn)行了性能評(píng)價(jià),優(yōu)選了懸浮劑;改進(jìn)人造膠結(jié)巖心結(jié)構(gòu)及注入方式,解決了瀝青顆粒注入過程中在端面聚集的問題;利用填砂管進(jìn)行驅(qū)替調(diào)剖實(shí)驗(yàn),評(píng)價(jià)了瀝青顆粒注入性能,包括配伍性、封堵性,確定了瀝青顆粒的注入粒徑與滲透率的匹配關(guān)系,對(duì)不同滲透率巖心,優(yōu)選了最佳注入量。研究結(jié)果表明,加入濃度為2%的KCl溶液作為分散劑可以對(duì)瀝青顆粒起到較好的分散作用;通過對(duì)三類瀝青顆粒的封堵率實(shí)驗(yàn)和耐沖刷實(shí)驗(yàn)確定瀝青顆粒粒徑為0.06mm~0.1mm時(shí)調(diào)剖效果最佳。且隨著調(diào)剖劑段塞量的增大,堵塞率和殘余阻力系數(shù)相應(yīng)增加。隨著調(diào)剖劑段塞的增大,突破壓力增大,突破時(shí)間延長。說明調(diào)剖劑的封堵性能和耐沖刷性能十分優(yōu)良。另外,根據(jù)實(shí)驗(yàn)結(jié)果開展了調(diào)剖劑體系注入濃度、調(diào)剖半徑及段塞組合方式的實(shí)驗(yàn)研究,最終確定了注入濃度3500mg/L、調(diào)剖半徑為井距1/3~1/2、段塞組合方式為高-中-高的段塞組合方式為最佳注入?yún)?shù),對(duì)瀝青顆粒型調(diào)剖劑的現(xiàn)場應(yīng)用提供實(shí)驗(yàn)依據(jù)。
[Abstract]:The application of bitumen particle profile control in high water cut stage of oilfield development can not only adjust the contradiction between layers, enlarge the sweep volume, but also improve the oil displacement efficiency. However, it is found that the effect of different wells is very different and the effect is unstable, the reason is not clear. Therefore, it is necessary to carry out the research on the adaptability and parameter optimization of asphalt particle profile control through laboratory experiments. Based on the investigation and investigation of related literature, the mechanism of asphalt profile control is expounded in this paper. By detecting the parameters of particle size distribution, suspension rate and bonding temperature, the performance of asphalt particles provided in the field is evaluated, and the suspension agent is selected. The artificial cemented core structure and injection method were improved to solve the problem of asphalt particle accumulation on the end surface during the injection process, and the displacement profile control experiment with sand filling pipe was carried out to evaluate the injection performance of asphalt particle, including compatibility, plugging property, etc. The matching relationship between the injection particle size and the permeability is determined and the optimum injection rate is selected for the cores with different permeability. The results show that adding 2% KCl solution as dispersant can disperse asphalt particles well. According to the plugging rate test and scour resistance test of three kinds of asphalt particles, the profile control effect is the best when the size of asphalt particle is 0.06mm~0.1mm. The plugging rate and residual resistance coefficient increase with the increase of the slug volume of profile control agent. With the increase of profile control slug, the breakthrough pressure increases and the breakthrough time is prolonged. The results show that the plugging performance and scour resistance of profile control agent are very good. In addition, based on the experimental results, an experimental study was carried out on the injection concentration, profile control radius and slug combination of profile control agent system. Finally, the injection concentration of 3500mg / L, the profile control radius of 1 / 3 / 1 / 2 of well spacing and the slug combination mode of high-medium-high slug combination are determined as the best injection parameters, which provides the experimental basis for the field application of asphalt particle profile control agent.
