The role of light ethyl cellulose HEC in oil drilling
In all kinds of mud needed for drilling and fracturing, the mud mud can obtain good fluidity and stability by using ethyl erythrovisol HEC as the adjuator. In the drilling, high mud capacity can be achieved, and a large amount of water can be prevented from penetrating into the reservoir from the mud, thus stabilizing the production capacity of the reservoir.
When drilling for oil and gas, excessive fluid loss can lead to shale expansion, which can lead to wall shrinkage or even collapse. This can lead to increased drilling time and cost, and worse, can lead to hole abandonment. Fluid loss control agents must be used in the drilling process. The addition of fluid loss control agents during drilling can form a flexible and dense filter cake on the parallel wall to reduce fluid loss, protect the reservoir and stabilize the well wall
Light ethyl cellulose HEC can be used as thickening agent and cementing agent for workover fluid. Helps to provide a clear, low solid content solution, which greatly reduces damage to oil and structure.
The thickened liquid with light ethyl cellulose HEC is easily broken down by acids, enzymes or oxidants, greatly improving the ability to recover hydrocarbons. Light ethyl cellulose HEC is used as a proppant carrier in well fluid.
The drilling fluid configured with ethyl cellulose HEC can effectively improve drilling and stability due to its low solids content
These performance inhibitors can be used in medium to high hardness rock formations as well as heavy shale or shale drilling. In cement strengthening operations, ethyl cellulose HEC reduces hydraulic friction and minimizes water loss from lost rock tools.
