Description
The utility model belongs to azimuthal resistivity well logging, sphere focusing logging and the section gauge logging probe apparatus in geophysical exploration technology field, particularly a kind of oil well.
As everyone knows, in the exploration and production run of oil, oil well can be divided into uncased hole and cased well two classes, need measure parameters such as hole diameter, hole deviation, resistivity to uncased hole.Need a kind of device of being close to the borehole wall in order to obtain these parameters, hydraulic sidewall contact device designs in order to satisfy this requirement.At present, using wider is individual layer 4 arms or 6 arm hydraulic sidewall contact devices, 4 arms of telescoping ram or 6 arms utilize around can flexibly stretch to, because of the fluctuating of the borehole wall changes its outreach, and this variable in distance is synchronously converted to the variation of electric signal, deliver to surface instrumentation and carry out recording processing, just can obtain parameters such as hole diameter, hole deviation, resistivity.In order to satisfy higher logging requirements, understand stratum borehole wall situation more intuitively, need to increase the number of pole plate, improve coverage rate.And the individual layer hydraulic sidewall contact device is owing to be subjected to structural limitations, should not be too complicated, and can not solve the installation question of N arm (N＞6).Therefore, its measurement point mostly is 6 most, and measuring accuracy influenced by borehole condition bigger, the well logging coverage rate is lower, its logging effect is difficult to satisfy people's requirement higher to logging quality.
The purpose of this utility model is to provide that a kind of influenced by borehole condition little, well logging coverage rate height, and logging effect is directly perceived, can realize the novel telescoping ram of two N arms well logging functions with the satisfied needs of logging well.
The utility model is realized as follows.
On the basis of original individual layer N arm hydraulic sidewall contact device, increase one deck leverage and spring assembly again and become double-deck member structure.Ground floor (deserve to be called not only layer) leverage and the second layer (but also claiming lower floor) leverage are shared a power source, M ° each other/2 jiaos arrangements between the two-layer up and down leverage, and its upper and lower N arm of hydraulic sidewall contact device is unusual fluctuation formula working method.
The utility model has following advantage:
Adopt the telescoping ram of said structure, compare, on the borehole wall is measured,, the measurement coverage rate is doubled owing to increased by one times measurement point with individual layer N arm.Therefore, being subjected to during well logging irregularly around the borehole wall influences just for a short time, just can obtain well-log information preferably under the well logging condition of hole anomaly.
Adopt two N arm hydraulic sidewall contact devices, N orientation pole plate can respectively be installed on ground floor leverage and second layer leverage, be used for measuring 2N bar azimuthal resistivity curve, also can record N bar CAL with ground floor N arm telescoping ram, second layer N arm telescoping ram records N bar azimuthal resistivity curve.
The utility model also possesses expansion and measures item-function.
If any one pole plate on the second layer leverage is changed into the microballoon pole plate, so just can carry out microballoon and measure.
