Downhole motor with an enlarged connecting rod housing |
摘要 |
A bottom hole assembly is disclosed consisting of a downhole motor having a drill bit connected to its lower end and a bent sub attached to its upper end. The downhole motor includes a motor housing, a connecting rod housing and a bearing housing. The connecting rod housing has a bend angle formed on the housing, which is enlarged to enable the connecting rod to be tilted at a larger angle than otherwise possible. The enlarged connecting rod housing also functions as a near bit stabilizer.
