Abstract
The invention relates to a petroleum drilling and well cementing tool, in particular to a liner cementing rubber plug composite impacting device. The drill rod rubber plug of the device comprises a fixing nut, a connecting rod, a small rubber bowl and a bowl seat, wherein the fixing nut, the connecting rod, the bowl seat and a guide head are sequentially in threaded connection from top to bottom; the tail pipe hollow rubber plug comprises a hollow connector, a large rubber bowl and a hollow guide bowl seat, wherein the hollow connector is designed to be hollow, a fixture block groove matched with the fixture block is designed on the inner wall of the hollow connector, the lower end of the hollow connector is in threaded connection with the hollow guide bowl seat, and the large rubber bowl is sleeved on the outer side of the hollow connector. The invention realizes high bearing capacity, reliable fixation, simple structure and convenient use. Overcomes the defects of low bearing pressure, unsafe use, easy cement return, low return outside the pipe, cement plug left inside the pipe and the like of the existing well cementation rubber plug.
Description
Technical field:
The present invention relates to a kind of oil drilling cementing tool, the compound bruising device of particularly a kind of drilling liner cementing plug.
Background technology:
In the drilling liner cementing process, because the tail pipe operation can not build the pressure time with fixed attention by closing well, thereby needs bruising, and existing cementing plug bearing capacity is low; Use dangerously, be prone to cause cement to return, the outer low problem such as cement plug of staying in returning and managing of pipe; Workmanship is poor, and accident is many, and economic loss is big.
Summary of the invention:
The technical problem that the present invention will solve provides the compound bruising device of a kind of drilling liner cementing plug, and this device has realized that bearing capacity is high, fixing reliable, simple in structure and easy to use.It is low to have overcome existing cementing plug bearing capacity, uses dangerously, is prone to cause cement to return, the outer low deficiency of staying problems such as cement plug in returning and managing of pipe.
The technical scheme that the present invention taked is: the compound bruising device of a kind of drilling liner cementing plug, form by drilling rod plug and tail pipe hollow plug; The drilling rod plug comprises hold-doun nut, connecting rod, little glue bowl and bowl seat, and hold-doun nut, connecting rod, bowl seat, guide head are threaded from top to bottom in order, and connecting rod is set with little glue bowl outward, and the bowl seat outside is equipped with fixture block, and the fixture block installed inside has back-moving spring; Tail pipe hollow plug comprises hollow connector, big glue bowl and hollow guiding bowl seat; The hollow connector is designed to hollow; Be designed with the fixture block groove that is complementary with fixture block on the hollow connector inwall, hollow connector lower end is threaded with hollow guiding bowl seat, and the hollow connector outside is set with big glue bowl.
The bowl seat outside is provided with seal groove, and joint ring is installed in the seal groove.
The invention has the beneficial effects as follows: the present invention is because the mode that has adopted drilling rod plug and tail pipe hollow plug to match; Thereby have bearing capacity height, a fixing advantage reliable, simple in structure and easy to use; Avoid cement to return, stayed the outer low problem of returning of cement plug and pipe in the pipe.
Description of drawings:
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is done further detailed explanation.
Fig. 1 is the structural representation of drilling rod plug.
Fig. 2 is the structural representation of tail pipe hollow plug.
Fig. 3 is a structural representation of the present invention
The specific embodiment:
Like Fig. 1, Fig. 2, shown in Figure 3, the compound bruising device of a kind of drilling liner cementing plug is made up of drilling rod plug and tail pipe hollow plug; The drilling rod plug comprises hold-doun nut 1, connecting rod 2, little glue bowl 3 and bowl seat 4; Hold-doun nut 1, connecting rod 2, bowl seat 4, guide head 8 are threaded from top to bottom in order; Be set with little glue bowl 3 outside the connecting rod 2, bowl seat 4 outsides are provided with seal groove, and joint ring 5 is installed in the seal groove; Bowl seat 4 outsides are equipped with fixture block 6, and fixture block 6 installed inside have back-moving spring 7; Tail pipe hollow plug comprises hollow connector 10, big glue bowl 11 and hollow guiding bowl seat 12; Hollow connector 10 is designed to hollow; Be designed with the fixture block groove 9 that is complementary with fixture block 6 on hollow connector 10 inwalls; Hollow connector 10 lower ends are threaded with hollow guiding bowl seat 12, and hollow connector 10 outsides are set with big glue bowl 11.
Be pressed into the drilling rod plug after the drilling liner cementing cementing, replace into drilling fluid and make the drilling rod plug and to be fixed on the tail pipe hollow plug at tail pipe top compound, this moment, fixture block 6 snapped in the fixture block groove 9, continue to replace again into drilling fluid make seat of the present invention in the tail pipe bottom to bruising.
It is understandable that; More than about specific descriptions of the present invention; Only be used to the present invention is described and be not to be subject to the described technical scheme of the embodiment of the invention; Those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the present invention, to reach identical technique effect; As long as satisfy the use needs, all within protection scope of the present invention.
