Description
Technical field
The utility model relates to a kind of landwaste GR information online detecting device, belongs to geological logging rock sample GR radioactivity survey device technique field in oil and gas exploration and development process.
Background technology
Sieve residue log, as one of traditional logging method, has important effect in oil-gas resource exploration and development process.Utilize sieve residue log, on-the-spot geological technique personnel can identify the lithology of drilling strata intuitively, find and judge hydrocarbon-bearing formation, utilize sieve residue log data, also help drilling engineering safe construction, improve drilling well timeliness.
The fast development of drilling recent years technology, when improving bit speed, also caused the raising of cutting grain degree of grinding, particularly PDC drill bit, air drilling innovation technique are applied, cause the difficulty of traditional dependence manual identified landwaste lithology further to strengthen, be unfavorable for the development of petroleum industry, need new equipment, new method to help field technician to improve the reliability of sieve residue log achievement.
Patent documentation " a kind of landwaste GR ray analysis device (ZL200420120715.2) " is recorded, this patent belongs to rock sample measurement mechanism class, in application process, detected object is chip sample, need manual sampling, metering system adopts point measurement simultaneously, does not possess online measuring ability, and testing result is easily subject to the impact of sample sampling accuracy.
Utility model content
The utility model is can not continuous detecting for overcoming in above-mentioned prior art landwaste GR information, characterization processes is complicated, testing result objectivity is poor, be difficult to meet drilling technology fast development needs waits defect, and a kind of landwaste GR information online detecting device is provided.
The utility model by popping one's head in, holding wire, single-chip microcomputer, serial ports, Serial Port Line form; Probe is comprised of sodium iodide crystal, photomultiplier, acquisition process unit, probing shell, sodium iodide crystal, photomultiplier, collecting unit connect successively by holding wire, be fixedly mounted in probing shell, probe is connected with single-chip microcomputer through holding wire, single-chip microcomputer utilizes holding wire output landwaste GR information by serial ports, is convenient to on-the-spot geological technique personal identification lithology application.
While being GR actinism to sodium iodide crystal according to the landwaste GR information on-Line Monitor Device basic principle of technique scheme manufacture can with crystal generation photovoltaic reaction, produce charged particle, these charged particles excite crystal molecule and make it luminous.The total energy of photon is directly proportional to GR ray energy, and number of photons is directly proportional to incident amount of radiation, and incident amount of radiation is directly relevant with the lithology of measured landwaste.The light that crystal produces carries out multistage amplification through being coupled into photomultiplier, the signal of telecommunication after utilizing acquisition process unit to photomultiplier opto-electronic conversion gathers, by holding wire, deliver to single-chip microcomputer and carry out Treatment Analysis, obtain the GR information of drilling strata landwaste.
By real-time online, detect landwaste GR information in drilling fluid, be conducive to help field technician accurately to identify lithology, solved the problem that current sieve residue log faces.
This device probe is fixed on built on stilts groove, the GR information of cutting carring in direct-detection circulating fluid, there is the features such as cost is low, testing result is continuous, objective, be conducive to examinations variation of lithological situation, find sand shale, determine reservoir, help to improve the accuracy rate that petroleum resources is found, this device can be used on a large scale in geological logging field, has considerable economic and social benefit.
Accompanying drawing explanation
Fig. 1 is the utility model theory structure block diagram;
