Abstract
The utility model relates to an electronic self floating multipoint measuring instrument used for the measurement of a petroleum drilling well. The utility model comprises a fishing spear (1), a buoyancy bin (2), an instrument bin (3), a buffer (4), an extended rod (5) and a bottom supporter (6). The utility model is characterized in that the fishing spear (1), the buoyancy bin (2), the instrument bin (3), the buffer (4), the extended rod (5) and the bottom supporter (6) are connected in sequence, the tool is simple, the investment is low, the operation is simple, and the operation is easy, the self floating multipoint process technology is formed on the basis of the lower side fishing multipoint and casing and fishing self floating simple point, the original pulling put measuring multipoint and the down-hole fishing measuring multipoint are not required, to reduce the labor intensity of measuring multipoint, and the adoption of self floating fishing can fish out the multipoint instrument from the bottom of a hole when the downhole is complicated and the drill tool is jammed. The utility model has the advantages that the cost is obviously saved, the operational reliability is high, the utility model is free from environmental contamination, and can be widely applied in the self floating of the multipoint self floating measuring instrument in the petroleum drilling system.
Description
Technical field
The utility model is used for oil drilling and measures, specifically, be that a kind of electronics is from floating multimetering instrument, use this and formed the technology of electronics from floating multiple spot from floating instrument, survey multiple spot and pulling have formed on the basis of floating single-point and have floated the multiple spot technology certainly under salvaging, and have changed trip-out in the past and have surveyed multiple spot and bore the mode of operation and the technology of salvaging the survey multiple spot with winch down.
Background technology
The electronics multipoint instrument is the electronic instrument in widely used continuous measurement well hole deviation, orientation in the oil drilling, it is the important tool of understanding grasp and Controlling Borehole Trajectory, this from floating multipoint instrument under in a single day run into the complicated and drilling tool in down-hole when surveying multiple spot and meet when blocking, just can adopt very easily from the mode of floating pulling instrument is pulled out in drilling tool, thereby avoid causing scrapping of multipoint instrument because of bit freezing.Used electronics multipoint instrument costs an arm and a leg at present, and a cover is worth more than 20 ten thousand yuan, and complex structure.
In order to guarantee wellbore quality, sometimes a bite well will carry out 1-3 time multimetering, according to metering system in the past, usually the survey multiple spot gets into the end under being, circulation is clean, throws electronics multipoint instrument permanent position in drilling tool, pull out of hole and measure, and then be lowered to the directed well straightening of directed drilling tool, and needing brill 2 times, the time is longer.Run into bit freezing if pull out of hole after multipoint instrument is plunged into, multipoint instrument can't be salvaged, and causes multiple spot to scrap, and loses bigger.
Summary of the invention
The purpose of this utility model is to provide a kind of electronics from floating multimetering instrument, can pull multipoint instrument when running into the complicated and bit freezing in down-hole out, also makes a trip the shortening drilling period in order to reduce a time of surveying multiple spot.
The utility model is achieved in that and comprises fishing spear 1, buoyant cabin 2, instrument storehouse 3, snubber 4, extension bar 5, collet 6 that fishing spear 1, buoyant cabin 2, instrument storehouse 3, snubber 4, extension bar 5, collet 6 connect successively.
Be threaded between extension bar 5 and the collet 6.
Be provided with snubber 4 between instrument storehouse 3 and the extension bar 5.
Advantage of the present utility model is: ascent rate very desirable (from the shaft bottom to the well head come-up 12 minutes), its hole deviation, bearing data and single-point hang surveys, single-point from floating and the contrast of MWD (wireless drilling) data is very identical, and suitable is accurate.Thereby for the application of floating multipoint instrument certainly provides safety assurance, be lowered to the combination drill tool structure of single curved screw rod, adopt from floating multiple spot and measure, carry out compound creeping into or the well straightening directional drilling, reduce 1 time and make a trip according to the multiple spot data.Its economic benefit is very considerable.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is the utility model snubber 4, extension bar 5, the collet 6 inner structural representations that connect.
The specific embodiment
As shown in Figure 1, the utility model is made up of fishing spear 1, buoyant cabin 2, instrument storehouse 3, snubber 4, extension bar 5, collet 6, and fishing spear 1, buoyant cabin 2, instrument storehouse 3, snubber 4, extension bar 5, collet 6 connect successively.
As shown in Figure 2, by being threaded, between instrument storehouse 3 and extension bar 5, be provided with snubber 4 between extension bar 5 and the collet 6.
Must connect bottom anti-sticking pallet---collet 6 in the bottom in measuring apparatus storehouse, and can not connect common damper, prevent that instrument from snapping in the orientation joint hydrophthalmia and cause the generation of deviational survey accident.
The utility model is a kind of instrument that is used for oil drilling survey tool electronics from floating multipoint instrument, use this and formed the technology of electronics from floating multiple spot from floating instrument, survey multiple spot and pulling have formed on the basis of floating single-point and have floated the multiple spot technology certainly under salvaging, and have changed trip-out in the past and have surveyed multiple spot and bore the mode of operation and the technology of salvaging the survey multiple spot with winch down.
Instrument is simple, small investment, simple to operate, be convenient to manipulate, on the basis of surveying the certainly floating single-point of salvaging multiple spot and pulling down, formed floating certainly multiple spot technology, do not need trip-out in the past to survey multiple spot or survey the mode of surveying multiple spot of salvaging down, alleviating the labour intensity of measuring multiple spot, and when running into the complicated and bit freezing in down-hole, adopt and drag for greatly and can in time multipoint instrument be pulled out from the shaft bottom from floating.Reduce expenses significantly, economy is considerable, the functional reliability height, environmentally safe, can be widely used in the floating certainly of oil drilling system multimetering instrument, electronics can be popularized in an all-round way on oil drilling from floating multiple spot technology, improves the overall economic efficiency of drilling well.
