How to choose drilling mud cleaner?

XI'AN, China - April 26, 2015 - PRLog -- Mud cleaner is used to separate 47~76μm and 15~47μm solids from drilling mud. It plays a critical role in whole mud purification system. So how to choose a high performance mud cleaner will be very important.

There are a variety of structure for mud cleaner in market, such as circular, square arrangement, just with reasonable structure design, easy to operate and ensure desander and desilter work normally. It is unnecessary to much more pursuit contour structure

We should pay attention to the flowing points on choosing mud cleaner:

Firstly, the core part of mud cleaner is desander and desilter  hydrocyclone, since the hydrocyclone is scoured by mud sand constantly, it should also be included in the wearing parts. Choosing hydrocyclone firstly select product materials, there are two types in market: one is cast iron material, the other is polyurethane material. After investigating, the using company generally reflect the polyurethane cyclone is more durable and lightweight structure, low maintenance cost. The other point is to choose common specifications in market, such as 10” desander hydrocyclone, 4” desilter hydrocylone. Once damaged, easy to purchase nearby, saving time and reduce cost.

Secondly, mud cleaner is second and third purification equipment, choosing a mud cleaner matching with other equipment is especially important. So according to its last purification equipment-capacity of shale shaker, meanwhile considering the following purification equipment-using cost and request of centrifuge to choose drilling mud cleaner. For example, BWZS70-3P linear motion shale shaker capacity is 120m³/h (mud density: 1.2g/cm³, viscosity: 45s, screen: 40 mesh), according to solids content 10~20% calculating, the drilling fluids treated by shale shaker flowing into next stage need the max treating capacity of mud cleaner is about 108m³/h, according to experiment report on desander hydrocyclone, choosing a set of 10” Polyurethane cyclone will meet request. According to the same methods calculating, choosing 4 "polyurethane desilter hydrocyclone is ok.
