Description
Technical field
The utility model relates to a kind of well logging apparatus, specifically a kind of without wireline logging device.
Background technology
In logging operation, mainly take at present wireline logging and well logging during as main.Because well logging during device technique is complicated, expensive, wireline logging remains main logging technique at present.Wireline logging technique is mainly comprised of surface laboratory and tool string, is provided with by installation compositions such as power-actuated logging cable cylinder, logging cable, depth measurement device, ground instruments on surface laboratory.During logging operation, logging cable connects ground instrument and tool string, tool string is gone into the well by self gravitation, and depth measurement device is measured the depth of falling well of logging cable, and ground instrument is processed and recorded from the depth information of depth measurement device and the well logging information of tool string.
Along with the development of petroleum industry technology, than the higher directional well of traditional straight well efficiency and horizontal well, start progressively to popularize, the traditional cable logging technique of going into the well by tool string self gravitation is restricted, and some supplementary techniques start to occur.Mainly contain the wet joint method of carrying by drilling rod or oil pipe, coiled tubing is carried method, and down-hole crawl device is carried method, and drilling rod is carried the method etc. that pumps.The wet joint method that drilling rod or oil pipe are carried is the technique extensively adopting at present, need at least twice time well construction, and many servicing units, help logging cable to dock in down-hole with logger, often cause for various reasons docking unsuccessfully, damage even logger of logging cable.Coiled tubing conveying method adopts coiled tubing to carry tool string to go into the well and logging operation, needs in coiled tubing, to penetrate in advance logging cable, and adopts the special-purpose downhole device construction of coiled tubing.Crawl device conveying method in down-hole adopts the auxiliary tool string of carrying of downhole electric crawl device to go into the well, and is subject to downhole electric crawl device power limit, and the instruments weight of conveying is limited, and can only in cased well, adopt.It is to adopt special-purpose slim hole tool device string that drilling rod is carried the method for pumping, and downhole probe is hidden in drilling rod and goes into the well, and by increasing pump pressure, tool string is released to drilling rod, then carries out storage type logging construction.Because instrument diameter is too small, some instrument performances are restricted, and the improper instrument string release failure that also often occurs of the control of pump pressure even damages or loses instrument string in addition.
Summary of the invention
The purpose of this utility model is exactly the defect existing for prior art, and a kind of rational in infrastructure, simple and reliable process is provided, and success log ratio is high, effective strong without wireline logging device.
Its technical scheme is: this adopts structure enhanced type storage type logging instrument string without wireline logging device, and jointed rod or oil pipe, utilize drilling rod or oil pipe directly to push well, completes logging operation.By 1 tubing string switching pipe nipple, 1 battery pack pipe nipple, 1 reinforced storage type logging instrument string, 1 buffer-oriented device, 1 above flexible nipple, 1 above rotating short-knot and 2 above centralizers form.Tubing string switching pipe nipple, flexible nipple, rotating short-knot, centralizer, battery pack pipe nipple, reinforced storage type logging instrument string, centralizer, buffer-oriented device connect successively, and are connected to bottom drilling rod or oil pipe column by the tubing string pipe nipple of transfer.The utility model adopts structure enhanced type storage type logging instrument string, for the comparatively weak logger structure division of some frame for movements, as key sensors such as sonic system, side electrode array, induced electricity polar systems, take to increase Instrument shell wall thickness, strengthen axle diameter and adopt the measures such as high-strength material, under the prerequisite that does not affect its performance, to strengthening especially in its frame for movement, to adapt to drilling rod or oil pipe, directly carry the needs of going into the well.This can increase mud pulse generator and slurry generator without wireline logging device, possesses secondary electrical supply ability and the ability of uploading information, thereby extends the instrument working time and this is monitored in real time without wireline logging device duty.
During construction, with drilling rod or the direct mode of movement of oil pipe, this is sent to measuring well section without wireline logging device, then with drilling rod or the direct mode of movement of oil pipe, this is proposed to well head without wireline logging device.This carrying simultaneously, carries out log data acquisition and storage without wireline logging device voluntarily, returns to ground and goes into log after by playback process.This can connect different measuring apparatus strings as required without wireline logging device, can be applicable to cased well or the construction of naked rock borehole logging tool.
Compare with traditional cable logging technique, while adopting this to log well construction without wireline logging device, without wireline logging ground system, support.Carry wet joint method to compare with drilling rod or oil pipe, while adopting this to log well construction without wireline logging device, except not needing the support of wireline logging ground system, also removed wet joint butt-joint process from, and the trouble of straight well, inclined shaft and twice logging operation of horizontal segment, the risk of having avoided wet joint docking and logging cable to damage completely.Carry the method for pumping to compare with drilling rod, saved the technique that pumps downhole probe, avoided construction risk, firm machinery is strengthened tool string can be shock-resistant, and resistance to heavy drawing heavily pushes away, and can under complex hole condition, successfully go into the well, and its performance is also better than minor diameter instrument string.Comprehensive, while adopting this to construct without cable downhole device, compare with other method construction of current employing, there is simple and reliable process, high, the effective strong feature of success log ratio.When carrying out high angle hole, horizontal well and problem wells logging operation, advantage is more obvious.
