Abstract
The conventional single plug cement head and the fast joint are abnormal heavy because of the large volume, and can not be assembled and disassembled by the human power. The assembly and the disassembly need to be aided by the pneumatic winch even the crane, and the conditions is not easy to be realized in the operation on the small platform. The utility model relates to an isolated cement head tool which can realize the rapid well drilling in the well drilling field of the marine petroleum exploitation. The cement head is divided into a plurality of isolated parts, and each part is connected by the turnbuckle.
Description
Technical field
The utility model relates to can realize easy mobile a kind of cementing head instrument in the marine petroleum development drilling well field; Particularly a kind of split type cementing head.
Background technology
Offshore oil field development, drill ship need be rented to offshore drilling by oil company, during the drill ship launching-out operation, need operation fleets such as several tugboats that the operation support is provided simultaneously, by international practice, oil company is except that paying to drillng operation turnkey company the normal drillng operation expense, also to per diem pay the daily rental fee of drill ship and the correlative charges of operation fleet, ceaselessly carry out drillng operation at sea continuously so how to guarantee drill ship to greatest extent, shorten well construction period, just become oily company to reduce big restraining factors of drilling cost.
In concentrating the well cementing operation of boring the top layer, usually use 13-3/8 " single plug cement head and snap joint; conventional single plug cement head and snap joint are because volume is bigger; heavy unusually; that depending merely on manpower can't load and unload; need the auxiliary loading and unloading of compressed air hoist even crane, and these conditions are difficult for realization in the chain-wales operation.
The utility model content
In order to overcome the defective that exists in the prior art, improve drilling efficiency, the utility model provides a kind of cementing tool of light practicality.
The utility model provides a kind of cementing head, it is characterized in that: body is divided into a plurality of minutes body portions, between the each several part by screwed connection.
Have handle, backing pin on the branch body portion.
Cementing head is divided into three parts, is respectively top cementing head, middle part cementing head, bottom cementing head; The upper end of bottom cementing head forms screwed connection; The upper end of middle part cementing head is formed with screwed connection; The upper end of top cementing head forms the tamponade pipe joint.
Cementing head lower end, bottom forms sleeve pipe and links joint; On the lateral surface of bottom cementing head, also be provided with handle; Middle part cementing head lateral surface is provided with well cementation pipe joint and backing pin; The lateral surface of top cementing head is provided with handle.
The cementing head that the utility model provides is convenient to transportation, installs, is dismantled light practicality.
Description of drawings
Fig. 1 is split type cementing head schematic diagram;

The specific embodiment
The utility model provides a kind of split type cementing head.As shown in Figure 1, 2, cementing head is divided into three parts, is respectively top cementing head, middle part cementing head, bottom cementing head.Cementing head lower end, bottom forms sleeve pipe and links joint 7, and the upper end forms screwed connection 4; On the cementing head lateral surface of bottom, also be provided with handle 6, rotate with convenient, thereby the part of two split cementing heads is coupled together.Middle part cementing head lateral surface is provided with well cementation pipe joint 3 and backing pin 5, and wherein backing pin 5 can enter cementing head inside from a side of middle part cementing head and reaches the another side.The upper end of middle part cementing head is formed with screwed connection 2.Upper end cementing head lateral surface is provided with handle, and the upper end forms tamponade pipe joint 1.
The above only is one of the utility model embodiment, according to the size of cementing head, also cementing head can be divided into a plurality of parts and use.
