Description
Technical field
The utility model relates to a kind of down-in type marginal oil field underwater drilling basal disc for drilling ship that uses in the development operation of marginal field.
Background technology
Expansion year by year along with marine oil and gas development operation amount, the demand of underwater drilling basal disc is increasing, subsea template is a kind of equipment that the offshore oil drilling operation is used, be positioned over the subsea wellheads place, mainly play the guide bur well tool, accept subsea equipment and under water blowout preventer set, carry out the preboring producing well, use the direction peg on the basal disc to carry out effects such as jacket butt joint location according to the well spacing of arranging on the subsea template.The underwater drilling basal disc of porous eye generally has 2 * 2 specifications, 2 * 3 specifications, 3 * 3 specifications, 3 * 4 specifications, even larger sized basal disc arranged, wherein the basal disc weight of 2 * 2 specifications has just surpassed 30 tons, appearance and size reaches 9.8 * 5.5 * 4.3m, underwater drilling basal disc generally comprises main body frame and annex, wherein the basal disc main body frame will bear the impact force effect that jacket docks with the basal disc direction peg, impact force reaches more than 100 tons usually, therefore main body frame adopts the major-diameter thick-wall steel pipe to build usually, the form of structure of basal disc main body frame was the form that a plurality of cuboids are formed big cuboid in the past, the basal disc rod member has only main cross bar, main montant, main vertical rod, this form structure is simple, in order to guarantee the intensity of main body frame, the Cross section Design of rod member is very big, and is very heavy.
Underwater drilling basal disc is transported to offshore boring island from building the place lifting, and must use the lifting device lifting down to the seabed, underwater drilling basal disc in the past only welds a hanger respectively on its four angles, the lifting device that uses includes only the lifting short circuit of a band drilling rod screw thread, four wire rope and lifting shackle, during the underwater drilling basal disc entry, one end of four wire rope is connected on four hangers of lifting short circuit, an other end then is connected on the hanger of four jiaos of underwater drilling basal discs by shackle, the lifting short circuit is connected with drilling rod by the screw thread at its top, carries out transferring of underwater drilling basal disc.Because the volume and the weight of underwater drilling basal disc are bigger, for the purpose of safety, underwater drilling basal disc needs the maintenance level in hoisting process, but because the requirement of actual job, the underwater drilling basal disc structure can't be designed to symmetry usually, the center of gravity that causes underwater drilling basal disc not in drilling template in the heart, therefore, during the drilling template lifting, for making drilling template maintenance level, must adopt the different wire rope of length, make wire rope be straightened the back the Rendezvous Point above the drilling template to be positioned at the basal disc center of gravity directly over, but in actual mechanical process, because the position of wire rope Rendezvous Point is sign and reference not, therefore each bar length of steel wire rope is difficult to determine, if each length of steel wire rope is improper, in hoisting process, light then the inclination of drilling template takes place, then can cause wire cable rupture when serious, cause security incident because of stressed its tolerance range that exceeds of certain bar wire rope.
The utility model content
Problem to be solved in the utility model provide a kind of Stability Analysis of Structures, stressed rationally, alleviate a kind of down-in type marginal oil field underwater drilling basal disc for drilling ship of basal disc weight.
The problem that the utility model further will solve provides a kind of cooperate with lifting device, definite a kind of down-in type marginal oil field underwater drilling basal disc for drilling ship of lifting center of gravity.
The utility model solves the problems referred to above by the following technical solutions: a kind of down-in type marginal oil field underwater drilling basal disc for drilling ship, comprise basal disc main body frame, annex, wherein, the basal disc main body frame is the cuboid support body that fixedly is made of horizontal bars and vertical rod member, the basal disc main body frame is provided with vertical wellbore casings, its both sides are fixed with a pipe box, between horizontal bars, in horizontal bars and the rectangular frame that vertically forms between the rod member inclined support bar are set.
Vertical wellbore casings is arranged on horizontal bars and surrounds rectangular center, and inclined support bar one end between the described horizontal bars is fixed on the crosspoint of adjacent two horizontal bars, and the other end is fixed on the wellbore casings.
Inclined support bar upper and lower side in the rectangular frame that horizontal bars and vertical rod member surround is separately fixed on main body frame top, two horizontal bars in bottom.
The horizontal bars at the main body frame top of intersecting with the basal disc plumb line is provided with the cutting ferrule device, and the main body frame of basal disc is provided with the hoisting and locating fixture.
Described hoisting and locating fixture is a hanger, and hanger is arranged on the horizontal bars at main body frame top.
Described cutting ferrule device is a column construction, and its underpart is fixed on the horizontal bars at main body frame top, and the upper surface is provided with a counterbore, and described counterbore hole wall is provided with at least one J-shaped groove.
The basal disc main body also comprises well head cover, stake pipe box and horn mouth etc., and the annex of basal disc has nothing in common with each other according to the different purposes annexes of basal disc, mainly includes dashboard, cat ladder, lifting annex, anode, level gauge, fluorescence labelling or the like.
It is this principle of stable structure that basal disc main frame structure of the present utility model utilizes triangular structure, in the basal disc rectangular frame, increase many inclined support bars, the basal disc framework forms many triangular structures, makes that the basal disc frame construction is more stable, more reasonable stress, each rod member is stressed more even, therefore, under same load-bearing state, reduced the sectional dimension of framework mobile jib spare, the basal disc weight that alleviates has greatly reduced the basal disc cost.
The utility model is fixed with several hangers on the basal disc framework, be provided with a cutting ferrule device at the plumb line of basal disc and the position of basal disc main body frame roof intersection, this device is connected with the rigidity cylinder cutting ferrule of lifting device, can realize lifting and descending being rigidly connected and flexibly connecting of fashionable and basal disc, can guarantee the stationarity in the preceding hoisting process of basal disc entry, and can control the position and the orientation of basal disc easily, make the basal disc accurate positioning and simple easily, guarantee the stability of basal disc in the entry process, balance and safety reduce the influence that is subjected to ocean current when subsea template is located in the seabed.
