摘要:  渤海油田已由中浅油藏向中深油藏逐步勘探开发。渤海某区块中深地层主要为含砾细砂岩、砂砾岩、细砂岩夹泥岩。该类地层胶结致密、硬度大、抗压强度较高、研磨性强、可钻性差。为了提高机械钻速,缩短钻井周期,节约钻井成本,在渤海某井中首次使用了HPG复合冲击器提速工具,取得了显著效果。实践表明,该提速工具具有良好的应用前景,值得推广。

Abstract: With the deep exploration and development of Bohai oil field, it has been gradually developed from the middle and shallow oil reservoir to the middle and deep oil reservoir. The deep strata in a block of Bohai sea are mainly breccia, breccia and fine sandstone. This kind of formation is compact, hard, high compressive strength, strong abrasion, and poor drillability. In order to increase the mechanical drilling speed, shorten the drilling cycle and save the drilling cost. For the first time, HPG composite impactor speed up tool was used in a well in Bohai Sea, which improved the mechanical drilling speed of the applied well section, shortened the drilling cycle, and achieved remarkable results. The practice shows that the speed-raising tool has a good prospect for application.
