(57)【要約】 機械水力式復動型掘削用ジョーは、外側の筒状ハウジング(14)の内部に差込み式に支持された内部の筒状マンドレル(12)を備える。 マンドレル及びハウジングの各は、好ましくはネジによる内部連結により互いに連結された多数の筒状セグメントよりなる。 上方圧縮ピストン(134)及び下方圧縮ピストン(166)がハウジング内に摺動可能に配置され、それぞれ上方及び下方の実質的に密閉された水力室(132、164)を閉鎖する。 マンドレルの長手方向の運動がコレット(184)を組み合わせ、これが、マンドレルの運動方向に応じて上方ピストン(134)又は下方ピストン(166)のいずれかに伝達する。 一方のピストンが動かされると、組み合わせられた水圧室内の圧力が高くなり、マンドレルに更なる運動を与え、ドリルストリング内のポテンシャルエネルギーの増強ができる。 コレットは、マンドレルがハウジング内の特定点に達するまでは広がりが制限され、特定点に達したときコレットは広がり、マンドレルを急激に解放してそのハンマー面(32、21)がハウジングのアンビル面(44、41)と急激に衝突する。 |

A jarring tool operable for coupling within and generating an impact imparted to a downhole tool string. The jarring tool includes an upper housing, a lower housing, and a shaft coupled with the lower housing and extending into the upper housing. The upper housing moves axially relative to the lower housing along the shaft. The jarring tool also includes an accelerometer for detecting acceleration caused by an impact generated by movement of the upper housing away from the lower housing until corresponding impact features of the upper and lower housings collide. |

This invention relates to a jar used to dislodge tools stuck in a well. The jar includes two housing portions movable with respect to each other. A release collet forms a portion of one of the housings. A release sleeve is carried by a mandrel and is located within the release collet. After a given amount of movement of the housing with respect to the mandrel, the release mechanism is activated and the two housing sections rapidly move with respect to each other. A hammer portion of the mandrel then strikes an anvil in the anvil housing, thus applying an upward force to the tool lodged in the well. |

A downhole assembly includes a downhole tool, a downhole force-creating device, and a shock damper. The shock damper includes an outer housing including a first annular housing shoulder and a second annular housing shoulder. Each housing shoulder extends radially inward from the outer housing. The shock damper also includes a mandrel located at least partially within the outer housing. The mandrel includes a first annular mandrel shoulder and a second annular mandrel shoulder. Each annular mandrel shoulder extends radially outward from the mandrel. In addition, the shock damper includes an annular cavity radially disposed between the outer housing and the mandrel, and axially disposed between the housing shoulders and the mandrel shoulders. Further, the shock damper includes a spring disposed in the annular cavity. |

A transport assembly comprising: an attachment member attachable to a downhole tool; normally two rotatable members, connected to the attachment member, the rotatable members being arranged to rotate around their main longitudinal axis; a plurality of engaging members attached to each rotatable member and extending radially outwards therefrom with respect to the main longitudinal axis; the engaging members being helically arranged around the rotatable members. The transport assembly can thus be driven into a well in a ‘corkscrew’ type manner. Embodiments include a jarring mechanism which may be reset downhole and can jar attached tools in either direction. |
