摘要/Abstract

摘要： 水平气井弯曲井身设计及油套封隔的特点导致泡排剂难以投注至井底,水平段大量积液无法有效排出。为此,基于亚硝酸钠-氯化铵型自生氮气协同泡排技术原理,将氯化铵、亚硝酸钠、缓速酸催化剂分别与泡排剂混合,经高压冲压制作成分体式圆球状化学动力球,形成了水平气井分体式化学动力球排水采气技术,对该泡排体系的配方和性能进行了优选和评价,对施工参数进行了优化,并开展了现场试验。研究表明:分体式化学动力球泡排剂基础配方(质量分数)为45%氯化铵+35%亚硝酸钠+10%泡排剂(含稳泡剂)+5%缓速酸催化剂+5%高密度填料;分体式及圆球状设计既解决了泡排剂投注难题,又避免了反应提前触发的风险;每克反应物(45%氯化铵+35%亚硝酸钠)可产生108~147 mL的泡沫量及4.9~5.9 mL的携液量;试验井段塞流排液特征明显,排液量显著增加,平均日产气量提升6.66倍。该研究成果可为水平气井积液治理提供新的解决方案。

Abstract: Due to curved wellbore design and tubing-casing isolation by packers in horizontal gas wells,foamers are difficult to be delivered to the bottom of the wells,and large volumes of accumulated liquid in horizontal sections cannot be effectively removed.Therefore,based on the principle of synergistic foam drainage with sodium nitrite-ammonium chloride self-generated nitrogen,a split-type spherical chemical power ball was developed by mixing ammonium chloride,sodium nitrite,and a slow-release acid catalyst separately with a foamer,and fabricating them into split-type spherical balls via high-pressure stamping.A split-type chemical power ball dewatering and gas production technology for horizontal gas wells was formed;the formulation and performance of the foaming system were optimized and evaluated,construction parameters were optimized,and field tests were conducted.The results show that the basic formulation of the split-type chemical power ball foaming system(mass fraction)is 45% ammonium chloride+35% sodium nitrite+10% foamer (including foam stabilizer)+5% slow-release acid catalyst+5% high-density filler.The split-type and spherical design solves the problem of foamer placement and avoids the risk of premature reaction triggering.Each gram of reactants(45% ammonium chloride+35% sodium nitrite)can generate 108~147 mL of foam and 4.9~5.9 mL of liquid-carrying capacity.The test well exhibits pronounced slug-flow liquid unloading characteristics,the liquid production increases significantly,and the average daily gas production increases by 6.66 times.These results provide a new solution for liquid loading control in horizontal gas wells.
