| titleOfInvention | For the raw cotton linter of the ethoxylation of well finishing liquid and workover fluid |
| abstract | A kind of well finishing liquid and workover fluid composition, comprise water and at least one rheology modifier and/or fluid loss agent and other composition of at least one, according to desired attribute, other composition described is selected from following group: inorganic salt, shale stabilizer, corrosion inhibitor, weighting agent, defoamer and solid particulate in small, broken bits (such as wilkinite, attapulgite, sepiolite, calcium carbonate, etc.), wherein rheology modifier and/or fluid loss agent are the raw cotton linters of the raw cotton linter of ethoxylation or the ethoxylation of modification.Compared with the high molecular business HEC that purifying velveteen is obtained, the raw cotton linter of ethoxylation provides suitable or better stream becomes and viscosity performance.The raw cotton linter derivative of these ethoxylations is applicable in workover fluid, is particularly adapted in oilwell drilling operating process for improving the functional performance of well finishing liquid and workover fluid. |
