Preparation method of high-activity oil well cement expanding agent
The invention relates to a preparation method of a high-activity oil well cement expanding agent. The method comprises the following operation steps: step S1, preparing raw materials including limestone, alunite, fly ash and bentonite according to a component formula of the oil well cement expanding agent; s2, carrying out ball milling on limestone, alunite and fly ash to obtain a prefabricated material; s3, calcining the prefabricated material, and then rapidly cooling to obtain a sintered material; s4, stirring bentonite by using a mixer, and introducing water mist into the mixer by using an atomizing machine at the same time, so as to obtain pretreated bentonite; and S5, adding the sintered material, carrying out ball milling until the average particle size is 10-30 meshes, adding the pretreated bentonite, continuously carrying out ball milling until the average particle size reaches 100-200 meshes, and finishing ball milling, so as to obtain a finished product of the high-performance oil well cement expanding agent. The method has the beneficial effects that the product activity is high, the expansion effect is good, and the process is simple.
本发明涉及一种高活性油井水泥膨胀剂的制备方法，该方法操作步骤如下：步骤S1：按照油井水泥膨胀剂成分配方准备原料石灰石、明矾石、粉煤灰、理膨润土；步骤S2将石灰石、明矾石和粉煤灰进行球磨，得预制料；步骤S3：将预制料煅烧，然后快速冷却，得烧结料；步骤S4：用混料机对膨润土进行搅拌，同时用雾化机向混料机中通入水雾，得预处理膨润土；步骤S5：将烧结料加入球磨至平均粒径10～30目，加入预处理膨润土，继续球磨至平均粒径达到100～200目，结束球磨，得到高性能油井水泥膨胀剂成品。本发明的有益效果：产品活性高、膨胀效果好，且工艺简单。
