Abstract
The utility model discloses an outer tube of a clinometer, which is suitable for inclination survey in the well drilling of petroleum geology. The utility model is composed of an upper joint (1), poly ammonium ester foams (2), a seal ring (3), a main body (4), a woven wool (5) and a lower joint (6). When the inclination survey is needed, the instrument is positioned in the main body (4), and the upper joint (1) is tightened. The instrument is sent to a well bottom in a mode of pumping, and the pump is stopped after the inclination survey is carried out. The instrument floats out of a liquid level along with the outer tube, and the inclination survey process is completed.
Description
The utility model relates to a kind of improved inclinometer urceolus, and the particularly a kind of urceolus that can keep afloat is suitable for petroleum geology drilling well well logging.
Existing inclinometer urceolus has two kinds, and a kind of is the steel urceolus, is mainly used to measure the gradient of well in the drilling well, and not a kind of is the aluminium alloys urceolus, can measure hole deviation and measure the orientation.Their bulk density is all greater than 1, mainly contain two kinds of application modes, instrument is put into measured hole deviation and orientation in the well head drilling rod straight, obtain data by pulling out of hole, perhaps use wire rope to hang drill-hole survey and the orientation obtains data, they all can not be kept afloat.
The utility model is that a kind of deviational survey urceolus that has improved, the urceolus that can bubble through the water column will be provided.
Task of the present utility model is finished as follows: it is by top connection, and main body is knitted suede, lower contact, and sealing ring, the polyammonium grease foam is formed.Point of top connection, the other end has screw thread to be connected with main body, interior sky and filling polyammonium grease foam.The main body hollow wall is stained with knits the suede damping, is used to load the deviational survey instrument, and its two ends is a screw thread, and one is connected with top connection, adopts the sealing ring sealing, and the other end is connected with lower contact.One of lower contact has screw thread to be connected with main body, and the other end is a round end, interior sky and filling polyammonium grease foam.Cumulative volume proportion after the assembling makes the instrument in the main body of packing into can bubble through the water column with urceolus less than one.
Below with reference to accompanying drawing the utility model is described in further detail:
Figure one is a concrete structure sectional drawing of the present utility model.
With reference to figure one: it is by top connection (1), polyammonium grease foam (2), and sealing ring (3), main body (4), Knit suede (5), lower contact (6) forms. Top connection (1) is made by titanium-aluminium alloy or nylon, and one is Pointedly be convenient to minimizing resistance in service. Top connection (1) hollow, in fill polyammonium grease foam (2), the other end is Pin thread, and cover has two seals circle (3) to be connected with main body (4) and seals. Main body (4) is by titanium-aluminium alloy Make, hollow two is box, and main body (4) inwall is stained with one deck and knits suede (5) damping. Lower contact (6) Adopt titanium-aluminium alloy or nylon to make, one is that pin thread is connected interior sky and filling polyammonium grease with main body (4) Foam (2), lower contact (6) other end is knob, is convenient to reduce operating resistance and the power that withstands shocks. No longer demolition after lower contact (6) connects with main body (4) behind the instrument of packing in the main body (4), tightens Drilling rod is put in top connection (1), and turn on pump is sent into the shaft bottom deviational survey to the inclinometer urceolus, and deviational survey is complete, termination of pumping. Because the overall proportion of external tube of gradiometer is lighter than 1, external tube of gradiometer emerges rapidly, takes out external tube of gradiometer And inclinometer, obtain the deviational survey data.
Embodiment: when the needs deviational survey, instrument inserted tighten top connection (1) in the urceolus main body (4), and seal by sealing ring, put into the drilling rod of well head then, connect the kelly bar turn on pump instrument is delivered to shaft bottom wait deviational survey, deviational survey finishes termination of pumping, and instrument is carried under the buoyancy of urceolus and emerges, and takes out instrument and finishes the deviational survey process.
Claims (1)
- One by top connection (1), polyammonium grease foam (2), sealing ring (3), main body (4), knit suede (5), a kind of inclinometer urceolus that lower contact (6) is formed is characterized in that top connection (1) and lower contact (5) employing titanium-aluminium alloy or nylon makes, and hollow and in fill polyammonium grease foam (2), be stained with one deck in main body (4) is made by titanium-aluminium alloy and knit suede (5).
