How does a mature technology retain exuberant market competition vigor for a long time, the Bohai Sea drills academy of artesian well craft to be in charge of well cementation tool to develop the way on in end is, link market demand cheek by jowl, begin a technology to innovate ceaselessly, make technical level maintains all the time in domestic lead position. Up to on October 20, sales revenue of well cementation tool already achieved this courtyard this year last year 2 times of annual income.
Tool of tail pipe well cementation is the traditional advantage technology of academy of artesian well craft. Use end to be in charge of well cementation engineering technology to carry out end to be in charge of well cementation to be able to reduce bushing paragraph jackknife, reduce artesian well cost, also be helpful for prolonging wildcat life at the same time. Tail pipe hanger is the core tool of this technology. Academy of artesian well craft developed end of the first fluid pressure type to be in charge of hanger 1978, fill home is blank. Consider to develop through 20 old seriation, had mastered the engineering technology of mature form a complete set, develop production to give hydraulic pressure and mechanical, machine independently early or late - the end of standards of 18 kinds of the 5 sort such as hydraulic pressure double action measurement is in charge of hanger, reach reveal artesian well to had carried out service of technology of form a complete set for key point of well of all sorts of deep wells, extradeep well, complex well, inclined well, level, little well, a few products are judged to be national level new product. Promotion of this technology product uses 14 oil field of countrywide, use nearly 1000, successful rate achieves 96% above, export the nation such as Si Tan of Korea, Kazakstan, Mongolia, Sudan successfully still.

In last few years, this courtyard basis market demand, to end tool of tubal well cementation undertook deepness is developed. According to spot demand, artesian well academy solved allpass means end to manage the technical difficult problem of well cementation, the well cementation of pipe of tail of little well key point that formed allpass means end to be in charge of canal of well cementation, center to rinse two maturity is over well engineering technology. This technology can reduce bushing dosage, managing the time that gets cement stuff, still can undertake to old well repair side is gotten, save the fee that gets new well in great quantities.

2007, artesian well academy develops horizontal well end to provide well cementation tool again, in Beijing of China north oil field 11 broke a 13 levels well to undertake horizontal well end is in charge of well cementation tool to serve, the horizontal well well cementation that forms maturity of one a complete set of is over the design of well tool, make and manipulate a technology. In leaving a course to realize end to be in charge of, rotate to be in charge of hanger with end after hanging, rotate, raise grout substantially take sb's place efficiency, improve well cementation quality, academy of artesian well craft develops a tendency according to tool of foreign well cementation, undertook end is in charge of affusion mud technology to consider to develop gyral, the whirl of development tail pipe hanger already had field test requirement at present, fill home is blank.
