Why are shear pump used in oil drilling

In the process of oil drilling, a lot of mud treatment equipment will be used, and the shear pump is one of the necessary equipment. The molecular weight of the high molecular weight polymer used in the mud is high, and it is not easy to be hydrated when added directly. If there is no sufficient shearing by the shear pump, the polymer may block the vibrating screen in the first cycle, and a large amount of polymer will be lost. , increasing the drilling cost, and may also make the large-sized solid phase particles in the drilling fluid hard and difficult to remove.

In the drilling fluid, due to insufficient shearing, the polymer will produce many "fish eyes", which will damage the formation, reduce the formation permeability, and reduce the production of oil and gas layers. Therefore, the high molecular polymer needs to be pre-sheared, and then enter the drilling fluid system to improve the performance of the drilling fluid, in order to give full play to its role. The shear pump can provide high shear efficiency and speed up the dilution and hydration process of the polymer.

HL Petroleum has improved the shear pump developed on the basis of a large number of domestic and foreign shear pumps, forming a complete shear and hydration system, which can quickly shear, dilute and hydrate polymers.

The main advantages of the product:

1. Adopting the comprehensive mechanical sealing technology uniquely developed by the institute, novel and unique design, the first at home and abroad with advanced sealing performance, reliable operation and long service life;

2. Greatly improve the degree of hydration of soil moving particles, and can save more than 30% of bentonite;

3. Provide high shear force for rapid hydration of high molecular polymer (or clay), and solve the outstanding problem of polymer (or clay) in drilling fluid due to poor hydration;

4. The loss of mud cake and fluid flow is reduced, the shear rate of drilling fluid is reduced, and the gel strength is improved, thus reaching the advanced level of foreign products.
