Plugging agent for heavy oil thermal recovery, plugging suspension and preparation method thereof
The invention relates to a plugging agent for heavy oil thermal recovery, a plugging suspension and a preparation method thereof, and belongs to the technical field of oil exploitation. The plugging agent mainly comprises the following components in parts by weight: 35-50 parts of coal ash, 30-40 parts of a consolidation agent, 10-20 parts of desulfurized gypsum and 5-10 parts of a suspending agent. The plugging agent is simple in composition, economical, practical, low in price, resistant to the high temperature of 350 DEG C, suitable for thickened oil thermal recovery huff and puff, free ofinfluences of crude oil properties and water content, good in suspension performance, high in strength, low in cost and good in plugging performance; when applied to a thickened oil thermal recovery well, the thickened oil thermal recovery well plugging agent can fill stratum deficiency, plug gas channeling channels, restrain edge water propulsion, improve plane profile contradiction, increase steam swept volume and increase oil production and oil-gas ratio of the oil well. The coal ash is used as a component so that the environmental pollution can be reduced, the environmental protection pressure is reduced, the environmental protection treatment cost is greatly reduced, the plugging measure cost is reduced, and the plugging measure benefit is effectively improved.
本发明涉及一种用于稠油热采的封堵剂、封堵悬浮液及其制备方法，属于石油开采技术领域。本发明的封堵剂，主要由以下重量份数的组分组成：煤灰35～50份、固结剂30～40份、脱硫石膏10～20份、悬浮剂5～10份。本发明的封堵剂组成简单、经济实用、价格低廉，耐350℃高温，适用于稠油热采吞吐，不受原油性质及含水影响，悬浮性能好，强度高，成本低，封堵性能良好；在稠油热采井上应用可填充地层亏空，封堵气窜通道，抑制边水推进，改善平剖面矛盾，提高蒸汽波及体积，提高油井产油和油气比；并且利用煤灰作为组分能减少其对环境的污染，减轻环保压力，大大降低环保处理费用，降低堵调措施成本，有效提升堵调措施效益。
