海塔盆地防斜打快技术研究及应用

Research and Application of the Deviation Control and Drilling Fast Technology in Haita Basin

介绍了几种常用防斜、纠斜钻具组合。并针对海塔盆地地质特征,研究了几种适合于海塔盆地的钻井技术,现场试验表明它们能够明显提高机械钻速,较好地解决了大倾角地层的提速问题。最后指出海塔盆地在今后应该加快机械式随钻测斜和垂直钻井工具的研制,以较低成本实现机械钻速提高。

Several common packed hole and well straightening assemblies are introduced.According to the geological features in Haita Basin,corresponding kinds of drilling technologies have been researched. Field tests show that they can obviously improve the penetration rate and resolve the problem of increasing drilling rate effectively in high dipping formation.Finally,in order to improve the penetration rate at lower cost,it points out that Haita Basin should hasten the development of mechanical survey steering tool and vertical drilling tool in the future.
