PIBSI对油基钻井液性能影响研究
Effect of PIBSI on the Properties of Oil-Based Drilling Fluid
摘要
Abstract
5# mineral oil and 3# mineral oil were used separately to prepare the basic mud and the oil-based drilling fluid system at room temperature.PIBSI(polyisobutylene succinimide)with different concentration were added to investigate the effect on properties of the basic mud and oil-based drilling fluid system under different temperatures.The results showed that, PIBSI can improve sag stability and viscosity of the basic mud changes with the concentration of the PIBSI under low temperature(4 ℃).As for oil-based drilling fluid system,PIBSI can decrease the viscosity of the system under low temperature while showed little effect on the viscosity and the gel strength under room and high temperatures if the concentration of PIBSI was in the appropriate concentration (for the 5 # mineral oil based drilling system,the appropriate concentration was 2%,while for the 3# mineral oil based drilling system,the appropriate concentration was 0.2%).The larger the concentrations of the PIBSI,the lower the HTHP filtration loss will be.关键词
