Abstract
The utility model relates to a geologic steering wired while drilling measuring instrument, which is a while drilling comprehensive parameters measuring instrument in the oilfield drilling operation which is collected geological parameters and geometric parameters for the entire body. The measuring instrument is mainly composed of a special cable joint, an extension bar and a special structure directional short section, which can measure the geological parameters with disposable while drilling. Because of using while drilling measuring the geological parameters, immersion formation drilling fluid is less, therefore the measured geological parameters are reliable. Especially in horizontal well drilling, the utility model can be real-time tracking formation, therefore solving the problem that a borehole cannot be beat in the middle of the reservoir because of the formation change.
Description
The utility model relates to a kind of geosteering wired drilling measuring instrument, belongs to drilling well downhole instrument class.
In geological prospecting and the oil exploration process, in order to seek the geologic parameter of subterranean strata section, often use steering tool to measure the well geometric parameter and in conjunction with the comprehensive geology parameter, judge the subsurface structure state that certain is regional, during measurement, because the stratum utilizes apparatus measures a period of time very long at interval from drilled reaching, drilling fluid immerses darker to the stratum in the well, cause the parameter poor accuracy of measurement, therefore can bore on the stratum and open in the short time, drilling fluid immerses few cases to the stratum and goes down to measure the geologic parameter data, then is ideal process, and the utility model proposes for this purpose.
The utility model is that propose for the shortcoming that overcomes above-mentioned measuring apparatus a kind of promptly has comprehensive logging instrument function, again can be on the stratum the drilled geosteering wired drilling measuring instrument that accurately and timely measures downhole parameters in the short period of opening.
The utility model is achieved in that
The utility model comprises by ground and down-hole two and partly forming: wherein ground partly comprises cable reel in the existing technology, rig floor lower sheave, top sheave and rotating disk, and the downhole instrument that is linking by cable on the cable car partly, the utility model has adopted the conventional logging instrument, this device is to hang downhole instrument with cable head on instrument, instrument is run within the directed pipe nipple that links to each other with drill string in the well, and parts such as special joint, data-storing formula inserting tube, battery, GR instrument, guide shoe, geologic parameter measurement pipe nipple are housed in the instrument successively.During work, partly packed in the down-hole of this instrument earlier in the drilling tool, and with arriving bottom hole location under the drill string, when measuring downhole parameters, needs, to the cable energising, measure the well geometric parameter then by cable being communicated with butt joint with downhole instrument by the special joint that installs to instrument top, when the Rotary table for drilling machine rotary drilling, cable is stopped using, but the comprehensive geology parameter instrument of down-hole when partly still supply lines is surveyed, and measurement result is stored in automatically in the data storage of inserting tube 2.At this moment, cable is in open position from special joint, downhole instrument is left on does not promptly influence the measurement of creeping into and can not influence comprehensive parameters in the well, the battery pas power source that downhole instrument dependence itself is inner, make sensor and the signal generator above the geologic parameter measuring instrument can be in underground work, described power supply mode and signal transmission be to draw the realization that connects together of cable and cable in the top side opening of directed pipe nipple (6) on tiltedly (5) with special type.
The utility model distinguishing feature is when brill is turned up the soil layer, also be not immersed at drilling fluid and just measured underground initial parameter under the earth formation deep situation, energy actual response stratum truth, the utility model has adopted the cable of special joint in addition, lower going-into-well docks with downhole instrument down, can make its rig when rotary drilling, not use under the cable situation, downhole instrument can be stayed and continue to measure geologic parameter in the well, thereby having saved the operation of comprehensive logging instrument in the existing technology, the geologic parameter that is obtained is accurately more reliable.
The utility model is provided by following examples
Be described further below in conjunction with accompanying drawing
Accompanying drawing: the utility model structural representation.
Among the figure, special joint 1, data-storing formula inserting tube 2, battery 3, GR 4, extraordinary guide shoe 5, geologic parameter are measured compositions such as directed pipe nipple 6, side opening 7, cable reel 12, lower sheave 13, top sheave 14, rotating disk 15, cable 16, cable head 17, sensor 18, signal generator 19.
A kind of geosteering wired drilling measuring instrument that relates to, comprise by ground part cable reel 12, lower sheave 13, top sheave 14, rotating disk 15, and twine superincumbent cable 16, the down-hole is partly by special joint 1, linking data-storing formula inserting tube 2 (being gamma sensor) with cable connector by electrically contacting ring more than two groups successively on the directed pipe nipple of special joint the inside, battery 3, GR pipe 4, cable connector 17, sensor 18, signal generator 19, and be bound up on extraordinary guide shoe 5 below the GR pipe 4, geologic parameter is measured directed pipe nipple 6 and is formed, it is characterized in that described down-hole partly and ground partly be to rely on the cable head of special joint 1 to be lowered into the down-hole to dock with downhole instrument and realize powering, rotate at rig, in the time of can not using cable, downhole instrument is partly measured by battery 3 power supply carrying out geologic parameter, and power supply and signal transmission are to draw the realization that connects together of cable and cable in the directed pipe nipple 6 top side openings on oblique 5 by special type.
Claims (2)
1, a kind of geosteering wired drilling measuring instrument, it is partly: cable reel (12) by ground, lower sheave (13), top sheave (14), rotating disk (15), and be wound into cable (16) on it, down-hole part: be the data memory-type inserting tube (2) that on directed pipe nipple (6), is connecting successively, battery (3), GR pipe (4), extraordinary guide shoe (5), sensor (18), generator (19) is formed, it is characterized in that described down-hole partly and ground partly be to rely on the cable head of special joint (1) to be lowered into the down-hole to dock with downhole instrument, when the rig rotation can not be used cable, downhole instrument was by battery (3) power supply.
2, geosteering wired drilling measuring instrument according to claim 1 is characterized in that the transmission of the power supply mode of down-hole instrument and signal is to draw the realization that connects together of cable and cable in the top side opening of directed pipe nipple (6) on tiltedly (5) with special type.
