【摘要】：鉆孔漏失作為地質(zhì)鉆探工程中最普遍、也最難解決的技術(shù)難題之一,嚴(yán)重制約著地質(zhì)勘探的進(jìn)展。水泥作為一種傳統(tǒng)的灌漿固結(jié)材料,廣泛應(yīng)用于地質(zhì)勘探鉆孔灌注堵漏,具有使用方便、利于灌注、性能可調(diào)、耐久穩(wěn)定和經(jīng)濟(jì)環(huán)保等優(yōu)點(diǎn)。因此,開展?jié)M足復(fù)雜地層鉆孔堵漏要求的新型水泥基灌注材料研究,對(duì)解決復(fù)雜地層鉆孔堵漏技術(shù)難題提供了理論基礎(chǔ)與科學(xué)依據(jù),為推動(dòng)地質(zhì)鉆探技術(shù)的發(fā)展具有重要的研究?jī)r(jià)值與現(xiàn)實(shí)意義。硅酸鹽水泥和硫鋁酸鹽水泥是兩種常用于地質(zhì)勘探鉆孔堵漏的無機(jī)膠凝材料。但硅酸鹽水泥因其穩(wěn)定性差,凝結(jié)時(shí)間長(zhǎng),早期強(qiáng)度低,且易被孔內(nèi)地下水稀釋,堵漏效果往往不夠理想。硫鋁酸鹽水泥具有快硬、早強(qiáng)、抗凍和抗?jié)B性能好等優(yōu)點(diǎn),然而由于其凝結(jié)速度過快,粘度時(shí)變特性無法得到良好調(diào)控,因而往往也無法達(dá)到理想的灌注堵漏效果,并且也存在價(jià)格偏貴的問題。為了克服和改善無機(jī)膠凝材料在灌注堵漏方面的弱點(diǎn),國(guó)內(nèi)外專家學(xué)者對(duì)此進(jìn)行了大量的探索和研究。復(fù)合化是改善水泥灌注性能的有效途徑。研究表明,硅酸鹽-硫鋁酸鹽復(fù)合漿液具有獨(dú)特的水化協(xié)同效應(yīng),表現(xiàn)出了水化凝結(jié)速度快、直角稠化、初終凝時(shí)間間隔極短等優(yōu)良的水化凝結(jié)特性。因此,開展對(duì)硅酸鹽-硫鋁酸鹽復(fù)合漿液灌注性能和水化協(xié)同效應(yīng)的研究,可望為解決松散破碎、陡傾寬大裂縫等復(fù)雜地層鉆孔堵漏技術(shù)難題提供全新的思路。論文首先分別對(duì)硅酸鹽水泥和硫鋁酸鹽水泥的灌注性能進(jìn)行了測(cè)試分析,并且采用合適的外加劑分別對(duì)其進(jìn)行改性研究,為復(fù)合水泥漿液的研究做好了技術(shù)準(zhǔn)備。論文重點(diǎn)研究了不同配合比的硅酸鹽-硫鋁酸鹽復(fù)合水泥漿液的灌注性能,進(jìn)而通過正交試驗(yàn)確定了灌注性能滿足鉆孔堵漏要求的硅酸鹽-硫鋁酸鹽復(fù)合漿液優(yōu)化配方。為了進(jìn)一步探索硅酸鹽-硫鋁酸鹽復(fù)合漿液獨(dú)特的水化協(xié)同效應(yīng),論文通過采用數(shù)字式水泥水化熱測(cè)量系統(tǒng)測(cè)試分析了復(fù)合水泥體系的水化放熱速率從而間接反映了水泥的水化過程,揭示了復(fù)合水泥體系不同于單一體系水泥的水化過程,并且結(jié)合掃描電子顯微鏡以及X射線衍射儀等先進(jìn)試驗(yàn)儀器,研究了復(fù)合水泥體系的微觀組構(gòu)特征,進(jìn)一步對(duì)復(fù)合水泥體系的水化硬化機(jī)理進(jìn)行了探究。論文最后結(jié)合陽山礦區(qū)典型復(fù)雜漏失地層,將研制的硅酸鹽-硫鋁酸鹽復(fù)合漿液優(yōu)化配方用于現(xiàn)場(chǎng)鉆孔堵漏,并且取得了初步的應(yīng)用效果,為其在鉆探堵漏的進(jìn)一步應(yīng)用積累了寶貴的實(shí)踐經(jīng)驗(yàn)。論文的研究成果對(duì)于今后進(jìn)一步提高和完善硅酸鹽-硫鋁酸鹽復(fù)合體系水泥的灌注性能,具有較為重要的指導(dǎo)和借鑒意義。
[Abstract]:As one of the most common and difficult technical problems in geological drilling engineering, borehole leakage seriously restricts the progress of geological exploration. As a kind of traditional grouting consolidation material, cement is widely used in geological exploration, which has the advantages of convenient use, good for pouring, adjustable performance, durability and stability, economic and environmental protection, and so on. Therefore, the research on new cement-based filling materials to meet the requirements of drilling plugging in complex strata provides a theoretical and scientific basis for solving the technical problems of drilling plugging in complex formations. In order to promote the development of geological drilling technology, it has important research value and practical significance. Portland cement and sulphoaluminate cement are two inorganic cementing materials which are commonly used in geological exploration. However, because of its poor stability, long setting time, low early strength, and easy to be diluted by groundwater in the pore, Portland cement is often not effective enough. Sulphoaluminate cement has the advantages of fast hardening, early strength, good frost resistance and impermeability, etc. However, due to its high setting speed, the time-varying viscosity can not be well regulated, so it is often unable to achieve the ideal filling plugging effect. And there is also the problem of high prices. In order to overcome and improve the weakness of inorganic cementitious materials in perfusion plugging, experts and scholars at home and abroad have carried out a lot of exploration and research. Compounding is an effective way to improve the castability of cement. The results show that the silicate-sulphoaluminate composite slurry has a unique hydration synergistic effect, showing excellent hydration condensation characteristics such as fast hydration setting speed, right angle thickening, and very short initial and final setting time interval. Therefore, the research on the performance of silicate and sulphoaluminate composite slurry and the synergistic effect of hydration are expected to provide a new way of thinking for solving the technical problems of drilling and plugging leakage in complicated strata such as loose fracture and steep sloping wide fracture. Firstly, the performance of Portland cement and sulphoaluminate cement were tested and analyzed respectively, and the proper admixture was used to modify the cement paste, which made the technical preparation for the study of composite cement slurry. The paper focuses on the study of the perfusion performance of silicate-sulphoaluminate composite cement slurry with different mix ratio, and then determines the optimal formula of silicate-sulphoaluminate composite slurry which meets the requirements of drilling and leakage plugging by orthogonal test. In order to further explore the unique hydration synergistic effect of silicate-sulphoaluminate composite slurry, In this paper, the hydration heat release rate of the composite cement system is measured and analyzed by using the digital cement hydration heat measurement system, which indirectly reflects the hydration process of the cement, and reveals that the composite cement system is different from the single cement system in the hydration process. The microfabric characteristics of the composite cement system were studied by combining the advanced testing instruments such as scanning electron microscope and X-ray diffractometer, and the hydration hardening mechanism of the composite cement system was further explored. In the end of this paper, the optimized formula of silicate-sulphoaluminate compound slurry is applied to the field drilling and leakage plugging combined with the typical complex leakage formation in Yangshan mining area, and the preliminary application effect is obtained. It has accumulated valuable practical experience for its further application in drilling plugging. The research results of this paper have important guidance and reference significance for further improving and perfecting the pouring performance of Portland-sulphoaluminate composite cement in the future.
