Description
Technical field
The present invention relates to a kind of micro-sphere focus logging tool list telescoping ram, belong to petroleum well logging technology field.
Background technology
Micro-sphere focus logging tool belongs to micro-resistivity tool, and for measuring the stratum resistivity near borehole wall portion and flushed zone, whether its probe (pole plate) contacts good with the borehole wall, is to ensure that the key of logging quality. This instrument is generally made up of electronics, drive system, telescoping ram three part, and telescoping ram can be divided into hydraulic sidewall contact device and mechanical pusher by the difference of power source. During well logging, with telescoping ram, instrument probe and pole plate are adjacent to the borehole wall, to ensure good logging effect.
No matter existing micro-sphere focus logging tool is hydraulic sidewall contact device or mechanical pusher, two backup arms are opened all simultaneously or draw in, hydraulic sidewall contact device is (as shown in Figure 1, pole plate wall 36, hydraulic pressure pole plate 37, massage shell 38 and countermure 39) pole plate arm can only somewhat open about about 80mm, mainly opening by auxiliary and pole plate arm is pushed to the borehole wall, hydraulic sidewall contact device instrument when measuring peupendicular hole is in eccentric state. The pole plate of hydraulic sidewall contact device is arranged on very long rigid plate arm, no matter is peupendicular hole, inclined shaft and horizontal well, and when hole condition is irregular, pole plate all can not carry out angled flexible swing with borehole wall shape, it is impossible to ensure that pole plate has good contact with the borehole wall.
Mechanical pusher is (as shown in Figure 2, pole plate assembly 7, thrust plate 11, motor 24, backup main body 25, upper arm 26, backup inner arm 27, even joint 28, contiguous block 29, hole diameter potentiometer 30, backup spring 31, back up plate 32, even joint 33 and backup inner arm 34) two-arm be that symmetry is opened, when measuring peupendicular hole, instrument is in center, and pole plate can have the swing of certain angle with borehole wall shape. And when deviational survey well and horizontal well, the weight of instrument string makes pole plate can not carry out angled swing with borehole wall shape, so that pad electrode frame all can not touch the borehole wall well, thus resistivity value accurately can not be recorded. Because being that symmetry is opened and gathering, so in horizontal well, back up plate (auxiliary) follows the gathering of pole plate arm cannot measure hole diameter value. Chinese patent application 200810141446.0 discloses a kind of four arm hole diameters, microsphere, microelectrode pushing device, hole diameter and microsphere microelectrode can be measured respectively, but it is the same with foregoing telescoping ram, microsphere pole plate arm and microelectrode arm two-arm are that symmetry is opened, drawn in, it is only suitable for surveying peupendicular hole, when deviational survey well and horizontal well, equally exist foregoing problem, and the caliper logging arm opened easily meets card in down-hole. It addition, on-the-spot well logging proves, no matter it is hydraulic sidewall contact device or mechanical pusher, when deviational survey well and horizontal well, all can act on because of the weight of instrument string and rubber pad accelerates its abrasion, also can increase the chance card probability of instrument horizontal well operation simultaneously.
Summary of the invention
It is an object of the invention to provide a kind of micro-sphere focus logging tool list telescoping ram, it can meet the different logging requirements of peupendicular hole, inclined shaft and horizontal well, it is ensured that pole plate stress is moderate, fits well with the borehole wall in irregular hole diameter.
The concrete technology contents of the present invention is as follows:
Micro-sphere focus logging tool list telescoping ram by a four-bar mechanism, one with four-bar mechanism linkage slider-crank mechanism and a wear-resisting supporting mechanism form.
