What is a Casing Centralizer?
ZHENGZHOU,DEC 07,2016-Casing centralizer is a mechanical device around the casing to keep the casing from contacting the wellbore walls.The continuous 360 degree space around the casing is better to make the cement seal the casing to the hole wall.Casing centralizers play the importanct role in improving the cementing quality by preventing mud channeling and poor zonal isolation.Simply speaking casing centralizer is used for centralizing casing( also called running of casing ) and the prevention of differential sticking.
Casing centralizer is manufactured widely during oilfield serive. It is estimated that 8 million casing centralizers are manufactured and used every year all over the world wide.When casing centralizer manufacturers hear the number of centralizer,they would like to increase the demand for casing centralizers.However ,on the other hand,cementing operators may be interested to ask why we need so much casing centralizers.
In fact casing centralizer is also used extensively.Due to the poor cementing job,the wellbore problems happen and arise year by year. Therefore casing centralizer properties and placements directly or indirectly affect the quality of the cementing job.It is the important task for cementing operators and oilfield serice companies to choose the righ type of casing centralizer and place the right amount at the optimum positions on the casing to achieve a good standoff profile. There are two following casing centralizers in cementing operation.The first centralizer is bow spring casing centralizer which is traditional ,simple,low cost centralizer,as you know OD of the bow springs are slightly larger than the wellbore,so this kinds of bow spring centralizer is mainly used in vertical or slightly deviated wells.The second centralizer is rigid casing centralizer whose OD is smaller than the wellbore,it works well even in deviated wellbores. Rigid casing centralizers are slightly more expensive and can cause trouble downhole if the wellbore is not in excellent condition.

Arranging Casing Centralizer in Casing String When Running into Well
ZHENGZHOU, September 20,2016-Casing centralizer is designed to help operators to complete a sucessful primary cement job.At the same time,these centralizers can help land the casing string to planned depth in the well and remove the mud from the wellbore.Therefore proper casing centralizer selection can be important for improving cementing quality in casing string.
Generally it is said that it is with 2pcs casing centralizers for every casing pipe,placing too much casing centralizers in casing string can be easy to hinder running casing pipes into the hole and then increase the unnecessary cost for cementing operation,but too few centralizers on the casing string will not ensure proper sealing of the hole.
In the view of the above reason,it is time to develop one kind of way for placing casing centralizers in a casing string which would take into account the spatial position of the hole as well as the load of the casing string with a minimum number of centralizers.The most important factors of casing string load happen when the casing strings run into the hole are the unit weight of the casing string,the stiffness of the casing string,the technology of running the casing string run into a hole and the spatial placement of the hole's axis.

How to Place Casing Centralizer
ZHENGZHOU, September 09,2016-Casing centralizer is installed in order to keep the casing in the center of wellbore while cement is poured between casings and well walls.The rigid placement of casing centralizers can better casing standoff,which enables mud to leave the casing for high quality cementing. The import task that both operators and service companies face is to choose the right type of centralizers and place the right amount at the optimum positions on the casing to achieve a good standoff profile.For more information,plesae click URL:http://www.casingcentralizer.com/news/casing-centralizer-placement.html
