Description

一种高造壁性封窜堵漏剂及其制备方法
技术领域
本发明涉及油田化学技术领域,具体涉及一种高造壁性封窜堵漏剂及其制备方法。
背景技术
随着开发过程中的强采强注,地层经长期的注水冲刷,形成了许多次生大孔道;同时,受固井质量、射孔、地质构造、修井和油水井管理不当等因素影响,造成套漏或套管外水泥环管外窜通,严重影响油水井的正常生产。而常规的化学堵漏剂多以水泥类为主,水泥基材料是先天带有一定缺陷和微裂缝的脆性材料。封堵施工时,由于水泥浆流变形好、悬浮性差,进入封堵部位后,凝固前很容易漏失和沉淀,造成现场施工用量大、成功率不高和有效期短,使封堵成功率低,并且存在一定的安全隐患。
发明内容
为了克服了上述现有技术存在的问题,本发明提供了一种高造壁性封窜堵漏剂,该堵漏剂使用方法简单,施工方便,安全可靠,其具有良好的悬浮稳定性,初始粘度低,易泵注,封堵强度高,一次封堵成功率高,运输方便,适用条件广泛。
为了实现上述目的,本发明采用以下技术方案:
一种高造壁性封窜堵漏剂,由以下重量份的成分组成:高炉KZ微粉1-15份、高炉矿渣5-30份、G级高抗油井水泥10-45份、G级高抗超细油井水泥15-40份、硅酸钠8-25份、有机硅树脂微粉0.1-1份、纤维5-18份、聚阴离子纤维素钠1-15份、聚合氯化铝5-20份、空心玻璃微珠5-40份、木质磺酸盐10-30份、腐殖酸钾2-5份、熟石灰2-5份、磺化沥青粉1-3份;所述高炉矿渣粒径为100-1000目;所述G级高抗油井水泥粒径范围100-1000目。
优选地,上述高造壁性封窜堵漏剂,由以下重量份的成分组成:高炉KZ微粉5-10份、高炉矿渣10-20份、G级高抗油井水泥20-40份、G级高抗超细油井水泥20-40份、硅酸钠10-20份、有机硅树脂微粉0.1-0.4份、纤维10-20份、聚阴离子纤维素钠1-5份、聚合氯化铝5-10份、空心玻璃微珠10-30份、木质磺酸盐10-20份、腐殖酸钾2-4份、熟石灰2-4份、磺化沥青粉1-2份;所述高炉矿渣粒径为200-800目;所述G级高抗油井水泥粒径范围300-1000目。
上述的一种高造壁性封窜堵漏剂按下述步骤进行制备:将所需要量的全部组分添加到三轴搅拌机中搅拌30分钟,按每袋25或50公斤装袋;使用时按比例加水搅拌均匀,配制成具有良好悬浮性、流动性的堵漏剂浆体。
本发明的有益效果为:
本发明中纤维、木质磺酸盐与聚合氯化铝的存在可使堵漏剂在封堵部位可快速吸附交联形成三维网架结构,抑制堵漏剂向地层深部漏失,对层间差异大的井段处理半径均匀,对地层污染小,大大提高堵漏剂抗渗、抗破碎、抗冲击性能;聚阴离子纤维素钠作为一种螯合剂,使堵漏剂的中各组分利用化学键结合在一起,增加堵漏剂的强度,减少了堵漏剂的漏失和沉淀;硅酸钠能够渗入到堵漏剂的缝隙和孔隙中,堵塞孔通道,具有固化微膨胀和充填密实作用,强化了堵漏剂同套管、水泥石及地层之间的胶结界面的致密性,提高了堵漏剂的胶结强度和抗压强度,堵漏剂与封堵层形成了一个坚实致密的整体,同时减少水中硫酸盐对堵漏剂的腐蚀;同时有机硅树脂微粉与水泥材料发生化学反应,形成一层憎水表面来隔绝腐蚀介质对水泥的腐蚀,从而延长堵漏剂的寿命;空心玻璃微珠减少堵漏剂的孔隙率,提高表面的密实度,阻塞腐蚀介质深入堵漏剂的通道,提高了堵漏剂的使用期限。
本发明采用磺化沥青粉、熟石灰和腐殖酸钾复配可以形成可压缩性的胶团,该可压缩性胶团不仅可以封堵油水井的微裂隙,还可以提高本发明的造壁性。
本发明中堵漏剂各成分之间相互配合使其具有良好的悬浮稳定性,可满足现场和配液站两种配液方式,使堵漏剂初始粘度低,易泵注,封堵强度高,一次封堵成功率高,运输方便,适用条件广泛。封堵层内堵漏剂失水后浓度增大,堵漏剂快速发生物理、化学反应,使堵漏剂具有一定承压能力,且井筒内堵漏剂凝固时间较长且强度低,反洗井时堵漏剂不反吐,施工安全性高,易钻塞。
本发明所述的堵漏剂使用方法简单,施工方便,安全可靠,其具有良好的悬浮稳定性,初始粘度低,易泵注,封堵强度高,一次封堵成功率高,运输方便,适用条件广泛,主要运用油井封堵水或封底水、水井封堵大小孔道、油水井破损套管的堵漏、油水井封堵窜槽。
