华主席、党中央对石油工业作了重要指示,向我们发出了战斗号召,石油的发展速度要再加快,要为创建十来个大庆而奋斗,因此,加速石油勘探:亡作就成了目前的当务之急。我们钻探的目的层有砂岩、灰岩,而高产油气流往往出自裂缝相当发育的灰岩层段。根据我们河口地区钻井经验,钻遇这种地层往往发生漏失,或严重漏失。漏失量从几百方到上千方,对勘探工作带来严重影响。过去曾使用锯末、稻壳等纤维质和药品提粘堵 Chairman Hua and the party Central Committee made an important directive to the oil industry and sent us a combat call.

In the past, sawdust, rice hulls and other cellulosics and medicines were used to lift up the blockage
