QuickSEAL 壓差激活堵漏劑 Differential Pressure-Activated Lost Circulation Material
簡(jiǎn)介Introduction
QuiSEAL是一種由載流體、短鏈聚合物、單體、聚合引發(fā)劑組成的特殊流體，其中水化短鏈聚合物是重要活性單元，固體組分是密封劑體系內(nèi)的單體和聚合物在聚合活性物作用下交聯(lián)形成。密封流體是一種特殊乳液，分散相位是一類(lèi)具有活性?xún)?nèi)核的顆粒，活性?xún)?nèi)核的惰性殼層在外界作用下破裂，在管柱微泄漏孔隙內(nèi)反應(yīng)堆疊，實(shí)施原位密封，達(dá)到完整性快速修復(fù)目的。
QuiSEAL is a specialized fluid composed of a carrier fluid, short-chain polymers, monomers, and polymerization initiators. Among these components, the hydrated short-chain polymers serve as crucial active units. Solids within the sealing system are formed through the cross-linking of monomers and polymers under the influence of polymerization activators. The sealing fluid is a unique emulsion where the dispersed phase consists of particles with an active core. The inert shell layer surrounding the active core can rupture under external influences, allowing the active particles to react and stack within micro-leakage pores of the tubular column. This process enables in-situ sealing, thereby achieving rapid restoration of integrity.
性能及優(yōu)點(diǎn)Performance and advantages
l 具備長(zhǎng)期穩(wěn)定性和抗沉降能力，避免大體積凝固，保障井筒結(jié)構(gòu)安全；
l 無(wú)需定位漏點(diǎn)或鉆塞，充填修復(fù)后井筒清洗簡(jiǎn)單，且對(duì)井筒無(wú)腐蝕；
l 抗溫150℃，封堵后抗壓強(qiáng)度達(dá)20.0MPa，耐酸堿腐蝕，確保長(zhǎng)期可靠性。
l It possesses long-term stability and anti-settling capability, preventing large-volume solidification and ensuring the safety of the wellbore structure;
l There is no need to locate leakage points or drill out plugs. After filling and repairing, wellbore cleaning is simple, and the process is non-corrosive to the wellbore;
l It can withstand temperatures up to 150℃, achieves a compressive strength of 20.0MPa after plugging, and is resistant to acid and alkali corrosion, ensuring long-term reliability.
