A few days ago, of own research and development of company of group of big harbor oil field " use fast outfit without borer well cementation wellhead device " the project wins a state practical model patent, indicate the service promoted a technology of well cementation of company of group of big harbor oil field new standard. All the time since, well cementation industry uses couplet generally to carry the means of well cementation of tool of well cementation of the join on face of section derrick floor on the head. As the ceaseless development of technology of artesian well of big harbor oil field, oil project is used batch auger carry fast extremely urgent. To shorten well cementation is periodic, reduce intensity of well cementation construction, technology of well cementation of group of big harbor oil field serves a company from 2006 end begins project approving " upright island does not have borer well cementation technology of integrated form a complete set studies " . The research through nearly one year and carry out, this project tackles key problem successful, project of its form a complete set " use fast outfit without borer well cementation wellhead device " win a state practical technology is patent. " use fast outfit without borer well cementation wellhead device " the need when solving well cementation construction successfully comes back artificially close elevatory pipe nipple and head of well cementation cement, labor strength is great, to buckling difficulty, damage silk is buckled extremely easily, come back fast rate is controlled not easily also, silk is buckled bear press ability to cannot assure, construction safety hidden trouble is big wait for a problem, to ensuring well cementation construction is safe, shorten artesian well is periodic, provided technical safeguard. From 2007 the beginning of the year up to now, " upright island does not have borer well cementation technology of integrated form a complete set studies " in Cheng sea an artificial island is carried out smoothly already, in all well cementation 19 wells second, well test and verify the advanced sex of technical program, effectiveness and feasibility.
