Background technology
In the exploration and development process of oil gas field, in order to understand the oily situation on stratum, all to log well after the drilling well, the acquisition of well-log information mostly is to carry out wireline logging after the drilling well completion.In high angle hole and horizontal well construction, wireline logging instrument can occur and transfer difficulty, and bad the caving in of borehole wall situation caused construction inconvenience with clogging.Simultaneously because the intrusion of drilling fluid, bore log parameter and the also difference to some extent of situation of just boring when turning up the soil layer after the completion.Along with the development of drilling measuring technology, Geosteering Drilling Technology is widely used in the construction of horizontal well.Geologic steering drilling is to utilize measurement while drilling project data and measurement while drilling geologic data to control well track, real-time geologic data and reservoir data according to the shaft bottom are helped the situation of change that the site operation personnel monitor formation characteristics and stratum at any time, variation and characteristic to the stratum are made accurately judgement, effectively the control wellbore trajectory navigates within the optimum position in the payzone, avoid oil/aerosphere face, oil/water termination and water layer, thereby obtain the best effect of gathering.
Along with the development of geosteering, connector for logging while drilling is widely used, and all comprises the natural gamma logging instrument in nearly all connector for logging while drilling series.The most frequently used a kind of connector for logging while drilling series is resistivity and natural gamma instrument at present, but in the resistive formation area, resistivity logging while drilling generally all is to use single gamma survey instrument to measure because self accuracy limitations can't be judged the reservoir interface.The drill-following natural gamma measuring instrument is measured the gamma ray on stratum, its response mainly with the performance of probe, test the speed, the factors such as thickness of mud, hole diameter and drill collar are relevant.The single gamma survey instrument that uses at present substantially all is the probe type structure, gamma detector is placed in drilling rod or the drill collar, with drilling rod or drill collar certain annular space is arranged so that the mud circulation, will be through decay, the decay of annular space, the decay of instrument bearing shell and the impact of mud of drill collar when measuring like this natural gamma rays on stratum.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, and a kind of drill collar formula gamma survey instrument is provided, so that the certainty of measurement of gamma is high, has improved the resolution capability on stratum.
Its technical scheme is: comprise body, communication port, wear-resistant sleeve, battery, sealing ring, middle control circuit plate, gamma counting tube, the centre of body is the communication port that reads for data, and skin is equipped with wear-resistant sleeve; Chamber body is provided with battery, sealing ring, middle control circuit plate, gamma counting tube, described middle control circuit plate, gamma counting tube are installed in respectively on the circuit board mounting groove, and by sealing ring middle control circuit plate, gamma counting tube are sealed respectively, in a side of middle control circuit plate battery is installed.
Above-mentioned body is oil drilling tools joint shape, and an end is male joint, and the other end is the box joint.
The outside of above-mentioned battery is provided with the righting band, is provided with sealing ring between righting band and the battery.
The circuit board mounting groove that above-mentioned middle control circuit plate, gamma counting tube are separately fixed at chamber body.
Above-mentioned gamma counting tube is located at male joint one side of body, and the both sides of gamma counting tube are provided with sealing ring.
The beneficial effects of the utility model are: the utility model is installed in the special-purpose drill collar, contact distance with the stratum short, the measurement influence factor is little, so that the certainty of measurement of gamma is high, has improved the resolution capability on stratum, better help the technician to identify the stratum, carry out formation evaluation, evade the probing risk, make the oil reservoir of exploitation more, effectively draining Duan Gengchang reaches the purpose that improves well yield and reservoir recovery ratio.
