Especially the perforating technology in the exceptional horizontal wells such as slim - hole casing wells , large hole wells and complex wells is detailed
着重介绍了水平井射孔技术在小井眼、大井眼及复杂井况条件下特殊井中的技术要求和特点。
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
塔北地区水平井上部大井眼采用聚合物钻井液体系、下部井段采用聚磺钻井液体系、造斜段及水平段采用聚磺混油钻井液体系。
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
现场应用结果表明，聚合物钻井液体系解决了大井眼携岩问题；聚磺钻井液体系抑制能力、防塌能力、携岩能力强；聚磺混油钻井液体系的携带、悬浮岩屑能力及润滑性更好。
