Technical field
The present invention relates near a kind of system of measuring oil gas in mud downhole drill bit.
Background technology
Geophysical exploration is to follow petroleum industry and a science and technology producing and grow up, is mainly used in two fields of formation evaluation and completion evaluation, finally realizes search for oil and natural gas in stratum.Therefore, geophysical exploration is the physical characteristic of measurement in oil-gas exploration and development process, record, analysis Rock in Well or fluid, and reservoir is carried out to a kind of technology of Evaluation of Oil And Gas, is called again geophysical log, is called for short well logging.Well logging, as important branch and the basis of petroleum industry, has been given play to increasing effect just day by day.
Oil and natural gas is present in the space on stratum, and their existence brings some variations to the physical property of rock.The physical property of study of rocks, as the electrology characteristic of rock, acoustic characteristic, nuclear physics characteristic etc., has just formed the physical basis of various logging method.So formed several main logging methods, as electrical log, acoustic logging, nuclear logging etc., the hardware of these methods is realized and has just been formed various loggers.With logger well logging, gather the information of reaction formation physical property; With computer, process and analyze these information; Finally by log analysis professional, provide appraisal report, point out the Hydrocarbon Bearing Prospects of reservoir.In order to improve the confidence level of evaluation, during well logging, to combine well measurements under multiple logger, log analysis need to be carried out " comprehensively " with many logs and explain.The conventional method that realizes formation physical parameters measurement is to utilize cable that logger is put into well to realize, and referred to as wireline logging, uses till today always.
Along with going deep into of oil-gas exploration, the especially increase of high angle hole, horizontal well quantity, increasing well logging service has turned to well logging during by wireline logging.Well logging during is compared with wireline logging, it not only can be convenient to measure at high angle hole, horizontal well, and the more important thing is and can invade under condition seldom and measure at mud, avoided mud to invade determining the impact of undisturbed formation parameter, obtain the parameter of actual response formation physical property, thereby be widely used.The middle oily Co., Ltd that logs well under China National Petroleum Corporation (CNPC) follows the tracks of international advanced technology with boring instrument research center Deng Duojia research unit always, be devoted to autonomous innovation, ripe day by day to the grasp with the technology of boring, realized the measurement of formation resistivity, degree of porosity and lithology in drilling course, the manufacture level of the equipment of well logging during simultaneously also leaps to world's rank of advanced units.Along with the develop rapidly of the technology such as computer, information and network, all further fast and accurate to the collection of underground survey signal, transmission and processing; And the continuous lifting of well log interpretation troop quality and the enhancing of means, the explanation of more evaluating the well-log information on stratum provides rich basis.
Yet, with the variation of landing surface and geological conditions, particularly in compactness seismic exploration exploitation, in order to find and identification of hydrocarbon layer, during to formation evaluation, need parameter more, actual response formation physical property, this has higher requirement to logging method and measurement equipment.
Summary of the invention
The object of this invention is to provide near a kind of system of measuring oil gas in mud downhole drill bit.When oil drilling, need to continue to inject mud in well at well head, and be recycled to well head, in cyclic process, the firm landwaste that bores the layer formation of turning up the soil in shaft bottom will be sneaked in mud, its characteristic is changed, and the compacted zone that brill leaves, oil reservoir, the different layers such as gas-bearing formation and water layer landwaste makes characteristics of mud that different variations occur, ground is measured and uploaded to this characteristics of mud parameter having changed in real time, characterisitic parameter comparative analysis with aboveground entrance mud, and in conjunction with the data of other variety classes apparatus measures, carry out integrated interpretation, just can quicklook judge stratum oil-containing, gas, the characteristic of water, thereby directly find and identification of hydrocarbon layer.
The system of performing down-hole measurement on oil gas in slurry while drilling of the present invention by ground host machine control system, Embedded data acquisition system, sensor, mud pulse generator, driver, battery sleeve, orientation survey pipe nipple, data connecting short section with boring instrument, characteristics of mud parameter measurement pipe nipple forms.
The various measurement pipe nipples of this system carry out the measurement of down-hole formation and characteristics of mud parameter and realize wireless transmission in drilling process, utilize mud-pulse in drill string by metrical information transfer of data to ground, ground system is processed in real time.
Ground host machine control system mainly comprises the initialization of system, the assistance application instrument of the process control of well logging during operation, user GUI, telecommunication, well logging during operation.Embedded data acquisition system mainly completes collection and the pretreatment of primary signal, and sends data to calculating and processing that main frame carries out project data by network.
System can also be connected with teleprocessing center by network, and the result of current well logging during is sent to teleprocessing center.Utilize decision-making and the evaluation system at teleprocessing center, decision information can be arrived to well logging during scene by network-feedback, thus the operation process of guide field.
The electrode system of realizing the Measurement accuracy of circulating mud characterisitic parameter in drilling process need to be arranged on drill collar inner side, and the design and installation of electrode system are keys of the present invention.
Characteristics of mud parameter measurement pipe nipple comprises resistivity measurement, temperature survey and other parameter measurement, is installed in the groove of drill collar sidewall.
Mud resistivity measure portion is comprised of electrode system and interlock circuit.
Electrode system is comprised of four electrode retaining collars: wherein two, outside is emission electrode A and emission electrode B, and middle two is collecting electrode M and collecting electrode N.Electrode system is arranged in the annular groove of Zuan Collars sidewall, Ju Zuan Collars outer rim 14mm, and its investigation depth is about 7mm, has so just avoided stratum on the impact of measuring, and makes the mud resistivity that records more true.
