WHIPSTOCK ASSEMBLY |
摘要 |
A whipstock assembly (10) comprises a setting section (16) and a guide section (18) which are substantially rigidly connected together. In preferred embodiments, a fulcrum member (40) is provided which projects outwardly from the housing (20). When the whipstock assembly (10) is landed a coil spring (28) biases a wedge (34) upwardly and outwardly into contact with the casing (12). This pivots the setting section (16) and the guide section (18) about the fulcrum member (40) and biases the guide section (18) against the casing (12).
