Preparation method of toughening agent for well cementation in oil field
The invention discloses a preparation method of a toughening agent for well cementation in an oil field. Comprising the following steps: S1, weighing 30-60 parts of drilling solid waste and 10-30 parts of waste rubber particles, heating at 150-260 DEG C, stirring for 35-50 minutes, melting and uniformly mixing; s2, 5-10 parts of mineral fibers are added, and heating and stirring are conducted for 15-20 min at the temperature of 150-260 DEG C; s3, naturally cooling to room temperature, grinding, crushing, sieving with a 80-mesh sieve, infiltrating 1-4 parts by mass of 63-73% polybutadiene latex aqueous solution on the surfaces of the sieved powder particles, and mixing and stirring for 1.6-2.3 hours; and S4, drying the mixed and stirred mixture at 30-40 DEG C, and crushing to obtain the toughening agent for well cementation in the oil field. The method has the beneficial effects that the well cementation quality can be improved, the cementation degree with stratum rocks is enhanced, the rigid stress effect of the stratum is reduced, and the bearing pressure of an oil well casing is protected and reduced.
本发明公开了一种油田固井用增韧剂的制备方法。包括以下步骤：S1、称取30～60份钻井固废和10～30份废胶颗粒，在150～260℃下加热并搅拌35～50min熔融并混匀；S2、加入5～10份矿物纤维，在150～260℃下加热并搅拌15～20min；S3、自然冷却至室温,研磨粉碎过80目筛,再在过筛后的粉末颗粒表面浸润1～4份质量分数为63～73％的聚丁二烯乳胶水溶液,混合搅拌1.6～2.3h；S4、再将混拌搅拌后的混合物在30～40℃下烘干后粉碎,即得到油田固井用增韧剂。本发明的有益效果是：能够提高固井质量，强化与地层岩石的胶结度，降低地层的钢性应力作用，保护和降低油井套管承压力。
