Abstract
The utility model discloses a small platform combining sea area geology investigation and hydrogeololgy investigation and relates to an operation platform combining the sea area geology investigation and the hydrogeololgy investigation. The operation platform consists of a small-sized self-elevating drilling platform, a barge and a delivery pipe, wherein the small-sized self-elevating drilling platform is connected with the barge by a connecting ladder; and the delivery pipe is used for delivering mud onto the small-sized self-elevating drilling platform from a mud pond. By the combination form, drilling equipment is separated from material, a mud system, a living facility, a duty facility and the like, thereby reducing the born load of the small platform, so that the small platform can be used for the sea area geology investigation, the hydrogeololgy investigation and the well construction, therefore, the exploration cost is saved, the installation is simple and convenient, and the period is shortened.
Description
Technical field
The utility model relates to geology waterborne, hydrogeological investigation job platform, particularly marine site geology, hydrogeological investigation job platform.
Background technology
In marine site geology, hydrogeological investigation construction, because of strong winds and high waves, in the past oil drilling platforms that adopt add the barge combination more.Oil drilling platform is mainly used in submarine oil exploration and exploitation, and spud leg length can reach 70m, platform Gao Keda 135m, but 15000 tons of load-bearing, and the boring hole depth can reach 12000m, and large platform have the title on " marine island ".Be characterized in that the petroleum drilling large platform is firm, can resist big stormy waves and abominable sea situation.
Marine site geology, hydrogeological investigation drilling depth generally less (0-400m), hydrologic drill be light (50-100 ton), the probing cycle short (1-2 month).As use the petroleum drilling large platform, and build, tear open that the large platform work capacity is excessive, the construction period is long, it is high to require, to operate too complicated loaded down with trivial detailsly, cost is too high.
The utility model content
The utility model design-calculated purpose is in order to overcome the petroleum drilling large platform, builds, tears open that the large platform work capacity is excessive, the construction period long, it is high to require, and operates too complicated loaded down with trivial detailsly, and cost is too high, the defective of the needs of not competent marine site geology, hydrogeological investigation; And chain-wales is little because of load-bearing, can reach safety and stability, tears down and build conveniently, the purpose of marine site geology, hydrogeological investigation operation cheaply.
The technical solution of the utility model adopts following composite set to realize that this composite set comprises:
1) forms by small-sized jack-up drilling unit 1, barge 2 and delivery pipe 5;
2) be connected to connect ladder 4 between platform 1 and the barge 2;
3) delivery pipe 5 is devices of mud pit drilling well slurry conveyed on platform on the barge.
Described small-sized jack-up drilling unit 1 is the workplatform of exploration, mainly is rigging up and power machine, and it is formed and is of a size of: chain-wales: long 10-20m, the high 1.5-3m of wide 10-15m; 7 of buoyancy tanks; 4 of spud legs: diameter 0.5-1m, long 30-40m; Shoe: diameter 4-5m; High 1-1.5m.
Described barge 2 is made up of with the district 9 of guarding on duty material sections 7, living quarters 8.
Described connection ladder 4 is platforms with barge between be connected facility, the one end is fixing on platform, rotatable 0-90 ° of the other end.
Described delivery pipe 5 is the connection hoses that the slurry transportation of the making on the barge arrived drilling well.
Described rig 6 is geology or hydrologic drill, its drilling depth 0-400m.
The utility model is owing to adopted technique scheme, make the utility model device have following beneficial effect: 1) by this array mode, the utility model technology is put branch openings such as driling rig and material, mud system, living facilities, facility on duty, reduced the drilling platform load-bearing, make chain-wales be applicable to marine site geology, hydrogeological investigation operation, reduced and reconnoitred cost; 2) resettlement is flexible, simple; 3) shortened the cycle of reconnoitring.
