超高温抗盐聚合物降滤失剂的研制及应用
Development and application of ultra-high temperature anti-salt polymer fluid loss reducer
摘要
Abstract
Aimed at the present outstanding problem of filtration property adjusting and controlling and high temperature stability of ultra-high temperature water base drilling fluid around the world, the ultra-high temperature anti-salts polymer fluid loss reducer HTP-1 was developed. The action mechanisms of HTP-1 are as follows: ( 1 ) HTP-1 are largely and hardly adsorbed on clay particles and little changed by salt and temperature. (2) HTP-1 can improve particle size grading, reduce the permeability and improve compressibility observably of filter cake. Field application results of the polymer fluid loss reducer HTP-1 in ultra-deep well Shengke 1 and Bishen 1 show that the tolerance of HTP-1 to temperature is up to 240 ℃, to salt above 20％. The performances of HTP-1 in several base slurries have an advantage of treating agents around the world, and HTP-1 could meet the demand of ultra-deep well drilling under ultra-high temperature.关键词
