【摘要】：本文以PVA-1788、硼砂為原材料,合成了一種新型的固體降失水劑GWF-01S,合成過程中應(yīng)用了緊密堆積理論、顆粒級配理論、化學(xué)交聯(lián)技術(shù)、化學(xué)反應(yīng)熱力學(xué)和化學(xué)反應(yīng)動力學(xué)。首先研制了主體聚合物PVA-1788:通過改變單體濃度、引發(fā)劑濃度、反應(yīng)體系PH值、反應(yīng)溫度、交聯(lián)劑的種類等因素,分析不同條件下水泥漿的失水量變化情況,確定了合成主體聚合物的最佳條件。并對體系的性能進(jìn)行了分析,著重研究了反應(yīng)時間、反應(yīng)溫度、反應(yīng)物濃度、交聯(lián)劑加量和PH值對體系的影響。當(dāng)反應(yīng)溫度為40℃,硼砂濃度為0.3%時,反應(yīng)達(dá)到最佳狀態(tài)。其次,對合成的固體降失水劑GWF-01S的抗失水性、抗溫性、抗鹽性、與其他外加劑的配伍性能、穩(wěn)定性、防竄性和稠化性能進(jìn)行了分析。固體降失水劑GWF-01S加量為1.2%時,控制水泥漿失水效果較好,在實際固井操作中,取得了良好的效果,固井質(zhì)量較好,滿足現(xiàn)場固井要求。合成后的固體降失水劑GWF-01S可溶于水,同時由于降失水劑中的聚合物自身也較為穩(wěn)定,具有抗堿性,在含有電解質(zhì)的溶液中聚合物能夠有效的控制失水,但是對流變性沒有較大的影響。在實際施工中,聚合物不會化學(xué)降解也不會物理降解,方便保存且易于管理。固體降失水劑GWF-01S具有價格低廉、綜合性質(zhì)穩(wěn)定、生產(chǎn)及現(xiàn)場應(yīng)用方便等特點。
[Abstract]:In this paper, a new solid reducer GWF-01S was synthesized with PVA-1788, borax as raw material. The close packing theory, particle gradation theory, chemical crosslinking technique, chemical reaction thermodynamics and chemical reaction kinetics were applied in the synthesis process. Firstly, the main polymer PVA-1788 was prepared. By changing the monomer concentration, initiator concentration, PH value of reaction system, reaction temperature and the type of crosslinking agent, the water loss of cement slurry was analyzed under different conditions. The optimum conditions for the synthesis of the main polymer were determined. The effects of reaction time, reaction temperature, reactant concentration, amount of crosslinking agent and PH value on the system were studied. When the reaction temperature is 40 鈩，
