polysulfide n.多硫化物。

polysulphide

Field using indicates that the polymer drilling fluid is suitable for the large size hole because of its remarkable cuttings removal ability ; and polysulfide drilling fluid shows its strong inhibition , anti - sloughing and good cuttings transportation ; while for polysulfide drilling fluid mixed with oil , it has better cuttings removal , suspension and lubricity , which are desirable for horizontal drilling 現場應用結果表明,聚合物鉆井液體系解決了大井眼攜巖問題;聚磺鉆井液體系抑制能力、防塌能力、攜巖能力強;聚磺混油鉆井液體系的攜帶、懸浮巖屑能力及潤滑性更好。

Different drilling fluid systems have been used in the horizontal well drilling in north tarim area , more specifically , polymer drilling fluid is used in the top hole of large size , and polysulfide drilling fluid for the lower interval ; for the building section and horizontal interval , polysulfide drilling fluid mixed with oil is used 塔北地區水平井上部大井眼采用聚合物鉆井液體系、下部井段采用聚磺鉆井液體系、造斜段及水平段采用聚磺混油鉆井液體系。
