Temporary plugging agent for plugging drilling cracks in oil exploitation and preparation method of temporary plugging agent
The invention relates to the technical field of temporary plugging agents for oil exploitation, in particular to a temporary plugging agent for plugging drilling cracks in oil exploitation and a preparation method of the temporary plugging agent. The temporary plugging agent comprises the following raw materials in parts by weight: 80-100 parts of granules, 20-30 parts of a fiber material, 10-20 parts of quartz sand, 4-8 parts of a nucleating agent, 4-8 parts of a compatilizer, 2-4 parts of a lubricant and 2-4 parts of a stabilizer. According to the invention, ions on the surfaces of the particles can form continuous conductive channels among the particles, so that the temporary plugging agent is endowed with electric ion performance, when the temporary plugging agent is added into a well for plugging treatment, the temporary plugging agent can generate electrostatic adsorption on powder particles on the wall of the well during flowing, and the powder particles are uniformly dispersed along with the flowing of the flowing temporary plugging agent. When the temporary plugging agent is used, powder particles on the well wall can be sucked into the temporary plugging agent, the effect of self-cleaning of dust particles on the well wall is achieved, the attachment effect of the temporary plugging agent on the well wall can be improved, and therefore the plugging effect of the temporary plugging agent is improved.
本发明涉及石油开采暂堵剂技术领域，具体为用于石油开采钻井裂缝封堵的暂堵剂及其制备方法。该暂堵剂包括以下重量份原料：80～100颗粒料、20～30份纤维料、10～20份石英砂、4～8份成核剂、4～8份相容剂、2～4份润滑剂及2～4份稳定剂。本发明中，颗粒表面的离子可以在颗粒之间形成连续的导电通道，从而使得暂堵剂被赋予电离子性能，在暂堵剂加入井内进行封堵处理时，暂堵剂在流动时可以对井壁的粉末颗粒产生静电吸附，随着流动暂堵剂的流动，井壁的粉末颗粒会被吸入暂堵剂的内部，实现对井壁灰尘颗粒进行自清理的效果，能够提升暂堵剂对井壁的附着效果，从而提升了暂堵剂的封堵效果。
