【摘要】：借助于烴源巖生排烴模擬技術(shù),開展了加熱溫度、加熱速率、恒溫時間、水質(zhì)量分數(shù)等不同邊界條件對油頁巖原位轉(zhuǎn)化開采影響的模擬實驗。結(jié)果表明:升高轉(zhuǎn)化溫度、降低升溫速率、延長恒溫時間均有利于提高原位轉(zhuǎn)化出油率和改善油品;流體壓力過度升高對油品稍有改善,但出油率有所降低,且過高的流體壓力(如超過開采層上覆巖層壓力)會對地面工程產(chǎn)生破壞影響;高溫地層水可能作為催化劑、反應(yīng)物和溶劑參加反應(yīng),促進非共價鍵的斷裂,提高出油率。在此基礎(chǔ)上,提出了在干餾轉(zhuǎn)化過程中加入額外的供氫物質(zhì)或高溫水中加入適量的水溶性催化劑提高油頁巖原位轉(zhuǎn)化開采出油率的方法。
[Abstract]:With the help of source rock hydrocarbon generation and expulsion simulation technique, simulation experiments were carried out on the effect of different boundary conditions, such as heating temperature, heating rate, time of constant temperature and water mass fraction, on oil shale in-situ conversion production.The results show that increasing the conversion temperature, decreasing the heating rate and prolonging the constant temperature time can improve the oil production rate and improve the oil quality, while the oil production rate is decreased when the fluid pressure is too high.Too high fluid pressure (such as over the pressure of overlying strata on the mining layer) will destroy the surface engineering, and high temperature formation water may act as catalyst, reactant and solvent to participate in the reaction, promote the fracture of non-covalent bond and increase the oil yield.On this basis, the method of increasing oil yield of oil shale by in-situ conversion was put forward by adding extra hydrogen material or adding suitable water-soluble catalyst in high temperature water in the process of retorting conversion.
