Analysis of application effect of microbial wax control technology in HT area
Because of the change of temperature,pressure and flow condition during the process of production and transportation,paraffin wax precipitates from crude oil continu-ously,which results in wax deposition in wellbore and pipeline.As a new technology,micro-bial wax control has been widely concerned,but it is necessary to select appropriate micro-bial wax control bacteria liquid according to the field environmental conditions to effectively solve the problem of oil well wax.Through the determination of crude oil viscosity,the con-tent of bacteria,the contrast diagram of load variation to verify its wax control effect.After 180 d field test,the wax deposition period of 4 oil wells in HT block has been prolonged ob-viously,and good wax control effect has been achieved.
