利用油渣或含油污泥制成的选择性堵水剂及其制备方法
摘要：
本发明提供了一种利用油渣或含油污泥制成的选择性堵水剂及其制备方法，以重量百分比计，制备所述选择性堵水剂的原料包括以下组分：油渣或含油污泥20％-40％、沥青5％-20％、两性离子表面活性剂0.2％-1％、超分散剂0.5％-2％、固相颗粒1％-10％和余量的水。本发明提供的利用油渣或含油污泥制成的选择性堵水剂具有制备工艺简单、原料来源广、价格低廉、环保友好，选择性堵水剂与地层配伍性好等特点，而且该选择性堵水剂的封堵强度大，选择性堵水能力强，对油层无伤害，不污染地层，适应油藏类型广。
摘要（英）：

The invention provides a selective water blocking agent prepared from oil residues or sludge containing oil and a preparation method thereof. The selective water blocking agent is prepared from, by weight, 20-40% of the oil residues or the sludge containing oil, 5-20% of asphalt, 0.2-1% of an amphoteric surfactant, 0.5-2% of a super dispersing agent, 1-10% of solid-phase particles and the balance water. The selective water blocking agent prepared from the oil residues or the sludge containing oil has the advantages that the preparation technology is simple, raw material sources are wide, price is low, the selective water blocking agent is environmentally friendly, and the compatibility between the selective water blocking agent and a stratum is good. The selective water blocking agent is large in blocking strength, high in selective water blocking capacity, free of damage to an oil reservoir and a stratum and wide in application range of oil reservoir types.
