Abstract
An oil well surface casing cementing device is characterized in that a sealing head 3 with a liquid inlet 4 and a liquid outlet 5 is mounted at the upper end of a surface casing nipple 6, a connectingrod 2 is penetrated at the center of the sealing head, the upper end of the connecting rod 2 is equipped with an upper joint 1 while the lower end thereof is equipped with a connector 7, and a collarclamp 8 is mounted at a through hole processed on the pipe wall of the surface casing nipple 6. The oil well surface casing cementing device is simple in structure, convenient in installation and reliable in operation, can be adaptable to surface casing connectors with different heights when used for secondary cementing of oil-water well surface casings, can simplify associated processing equipment, and can not only bring convenience for operation but obviously increase construction efficiency of overhaul operation of oil-water wells.
Description
Technical field:
The utility model relates to a kind of oil field drilling tool, especially for a kind of oil well surface pipe cementing unit of oil-water well overhaul.
Technical background:
Before the utility model, each oil field carry out oil-water well be lowered to surface pipe again after during the heavy repair task of secondary well cementation, adopt the well cementation wellhead assembly of conventional drilling, because this process matched therewith is comparatively complicated, equipment is heavy more, often make troubles, influenced the efficiency of construction of oil-water well heavy repair task to operation.
Summary of the invention:
The purpose of this utility model is: the secondary well cementation provides a kind of oil well surface pipe cementing unit behind the surface pipe for oilfield oil well is lowered to again, because it is comparatively easy that this installs comparatively light, supporting equipment, and can be adapted to the surface pipe joint of differing heights, not only make things convenient for operation, also can obviously improve the efficiency of construction of oil-water well heavy repair task.
The purpose of this utility model realizes by following measure: a kind of oil well surface pipe cementing unit, comprise top connection, connecting rod, seal head, inlet, leakage fluid dram, connector, clip, it is characterized in that the table cover pipe nipple upper end of elongate tubular is equipped with the seal head of a band inlet, leakage fluid dram, the seal head center is coated with the connecting rod of a stock shape, connecting rod stretches out the outer upper end of seal head top connection is installed, and the lower end that connecting rod stretches in the table cover pipe nipple is equipped with connector; Be processed with open-work on the tube wall of table cover pipe nipple bottom, and on the outer tube wall of through-hole position, clip be installed.
The utility model is simple in structure, easy for installation, reliable operation, be used for the heavy repair task that oil-water well is lowered to secondary well cementation behind the surface pipe again, can be adapted to the surface pipe joint of differing heights, and can simplify process matched therewith equipment, not only make things convenient for operation, also can obviously improve the efficiency of construction of oil-water well heavy repair task.
Description of drawings:
Fig. 1 is the structural representation of oil well surface pipe cementing unit.
The specific embodiment:
Oil well surface pipe cementing unit is to be made of top connection 1, connecting rod 2, seal head 3, inlet 4, leakage fluid dram 5, table cover pipe nipple 6, connector 7, clip 8 etc.Table cover pipe nipple 6 upper ends of elongate tubular are equipped with the seal head 3 of a band inlet 4, leakage fluid dram 5, seal head 3 centers are coated with the connecting rod 2 of a stock shape, connecting rod 2 stretches out seal head 3 outer upper ends top connection 1 is installed, and the lower end that connecting rod 2 stretches in the table cover pipe nipple 6 is equipped with connector 7; Be processed with open-work on the table cover pipe nipple 6 bottom tube walls, and on the outer tube wall of through-hole position, clip 8 be installed.
The operating principle and the using method of oil well surface pipe cementing unit are: should this device be carried by top connection 1 before the well cementing operation and cause the well head place, and will show cover pipe nipple 6 lower ends and be connected with the surface pipe head for the treatment of sealing, again connector 7 is connected with the production casing head for the treatment of sealing, at this moment, just can close leakage fluid dram 5 and carry out cementing operation; Can inject well cementation liquid by inlet 4 in the construction, and enter annular space between production casing and the surface pipe by table cover pipe nipple 6, treat that construction is finished after, but breakdown leakage fluid dram 5 carries out discharge opeing, and then open clip 8, inject for putting liquid by inlet 4 and show to overlap flushing in the pipe nipple 6; Contrary operation by above-mentioned installation unloads this device at last, finishes well cementing operation.
