Abstract
The utility model relates to an air gun source suspension connecting plate, which is applied to geophysical prospecting for offshore oil. The air gun source suspension connecting plate is characterized in that an air gun is connected to the lower part of the suspension connecting plate through two vertical iron chains; the air gun is connected with a buttcock line cable and a high-pressure air tube; the other ends of the buttcock line cable and the high-pressure air tube are fixed on the suspension connecting plate through a fixed pressure block; a near-field submarine seal and a depth and pressure sensor are fixed on one side of the suspension connecting plate by a U-shaped fastener, and a clamping ring is arranged on the other side of the suspension connecting plate; and both ends on the upper part of the suspension connecting plate are provided with transversely connected iron chains. The air gun source suspension connecting plate has the advantages of being capable of hanging and connecting an air gun cluster of a rear dragging air gun source and reliably implementing excitation of the air gun, and realizing vertical suspension connection of the air gun cluster or a single air gun under water and fixation of the air gun cluster or the single air gun with an auxiliary quality monitoring component and a cable air tube bank. Moreover, a joint part does not bear impact and vibration of the air gun, and is difficult to damage and convenient to replace.
Description
Technical field
The utility model relates to the marine oil geophysical survey.Be that a kind of each air gun of marine air gun focus bunch or single air gun carry out the key that vertical hanging and front and back connect each other and hang web joint in water.
Background technology
In the geophysical survey operation, use air gun to carry out the geophysical prospecting for oil operation on the water as explosive source.According to the position of air gun source with respect to hull, be divided into the side machine type of hull two sides of a ship and stern after drag mode.
Compare with the side mode of hanging, the mode of dragging behind the stern is more suitable in the construction than deepwater field.Because the seismic prospecting task of deepwater regions is far more than the construction of shoal water zone, after drag the formula air gun more to be widely used.
At present, each airgun subarray comprises 4-7 air gun bunch unit usually.Each air gun bunch reliably is connected with top suspension buoyancy aid in order to reach, air gun bunch bears in air gun excites that powerful bubble impacts and each air gun of front and back bunch between reliable connection, need to make special suspension web joint.This parts work reliably whether, will influence the operating efficiency of seismic prospecting.
Summary of the invention
The utility model purpose is to provide a kind of air gun source to hang web joint, can for after drag the air gun of formula air gun source bunch to hang, connect, reliably implement exciting of air gun.
The utility model be achieved in that air gun source hang web joint mainly by air gun, vertically iron chains, laterally connect iron chains, near field subsea envelope, the degree of depth, pressure transducer, suspension web joint, buttock line cable and high-pressure air pipe and form, it is characterized in that: air gun is connected the below of suspension web joint by two vertical iron chains.Be connected with buttock line cable and high-pressure air pipe on the air gun, the other end of buttock line cable and high-pressure air pipe is fixed on by fixing briquetting and hangs on the web joint.Adopt U type fixation clamp to be fixed with near field subsea envelope, the degree of depth, pressure transducer in a side that hangs web joint.At the opposite side that hangs web joint snap ring is arranged, snap ring is to be used for fixing the proof rubber pipe when forming air-gun array.In suspension web joint both upper ends thereof horizontal connection iron chains is arranged.
When a plurality of air gun sources suspension web joints are connected into the air gun array, will laterally connect iron chains and connect respectively.The proof rubber pipe is fixed in the snap ring.The cable air bundle that is connected with instrument on the ship is arranged in the proof rubber pipe.Joint and buttock line cable, the high-pressure air pipe of cable air bundle are connected, and air gun just can have been worked under water.Be fixed with depthkeeping rope and buoyancy aid connecting many air guns array top, whole air gun array just can be off the stocks.This air-gun array can be realized reliably exciting of air gun after stern discharges the entry.That each parts hangs is normal, fixation, be easy to check, safeguard and change, and has reduced because of this Component Design and has fixed unreasonable shut down time of causing.
Be connected with air gun smoothly with tracheae for the ease of the buttock line cable that links to each other with air gun, fixedly briquetting is that 45 is installed.
Air gun hangs web joint, vertical iron chains, laterally connects iron chains, U type fixation clamp and snap ring and shackle, adopts stainless steel material to make.
The beneficial effects of the utility model: the utility model air gun source hangs web joint, can for after drag the air gun of formula air gun source bunch to hang, connect, reliably implement exciting of air gun.Realized that air gun bunch or single air gun vertical hanging in water connect fixing with attached quality monitoring parts and cable air bundle.On the powerful impact endurance test shock basis that whole web joint produces when satisfying reliable operation and bearing air gun and excite, simplified structure, reduce time that cable air Shu Weixiu needs to greatest extent, alleviate overall weight, easy and simple to handle.All parts adopt stainless steel to make.The connector of air gun buttock line cable, high-pressure air pipe and main body cable and tracheae partly adopts split type briquetting to be fixed on the web joint, has guaranteed that like this shank does not bear the impact endurance test shock of air gun, is not easy to damage, and it is convenient to change.
