摘 要：Microbial contamination and bacteria growth in the cementing makup water impact cementing operation and *** avoid the premature cement setting caused by microbial growth,the water is usually treated with biocides for microbial control before *** treatment will also prevent biodegradation of the added polymers and stabilize the slurry rheological ***-up water and cementing mix samples were collected from active drilling rigs in the *** 12 hours biocide addition program,the tested biocide at 50,100,250,and 500 ppm for cementing operations revealed acceptable control of both GAB and SRB numbers in one Field,but not in another *** 24 hours biocide addition program,revealed varying levels for control microbial contamination in cementing operations,with higher efficiency with Field B samples opposed to field A,and with better control at higher concentrations of tested biocide at 250,and 500 *** a recommendation therefore,usage of another biocide with a different chemistry at Field A is encouraged once a new biocide is selected.
