田菁粉是由田菁种子胚乳磨成的粉,它的化学成分主要为半乳甘露聚糖。 田菁粉可溶于水,它象通常的水溶性高分子那样可以用作水的增粘剂(交联后增粘能力更大)和降阻剂。 目前,在油田中,田菁粉主要用于配压裂液。 配压裂液用的田菁粉存在两个问题:一个是水不溶物含量高,另一个是溶解速度慢。 为了解决这两个问题,可以将田菁粉进行化学改性,即在田菁粉的分子结构中引入亲水
Sesbania Jing is the seeds of endosperm ground into powder, its main chemical components galactomannan. Sesbania powder soluble in water, it can be used as a water-soluble polymer such as water-tackifier (after cross-linking more viscous capacity) and Jiang Zuji. At present, in the oil field, Sesbania powder is mainly used for fracturing fluid. Sesame powder with fracturing fluid has two problems: one is the high content of water insoluble matter and the other is the slow dissolution rate. In order to solve these two problems, Sesbania powder can be chemically modified, that is, the introduction of hydrophilic in the molecular structure of Sesbania
