Abstract
A kind of setting of casing grouting blowout hookup, under well cylinder is arranged on offshore boring island, in sleeve pipe lower going-into-well eye cylinder, sleeve pipe passes in stratum from the lower end of well cylinder, toroidal cavity is had between sleeve pipe and well cylinder, lubricator is connected on the top of sleeve pipe, grout lines is connected with the bottom of lubricator, the upper end of delivery pipe is connected with the top of lubricator, the junction of delivery pipe and lubricator is higher than the junction of grout lines and lubricator, the upper end setting pressure table of lubricator, delivery pipe inserts in the toroidal cavity between sleeve pipe and well cylinder, leak-off pipe is installed in the side of well cylinder, the valve on delivery pipe is opened after setting of casing grouting terminates, the gases at high pressure be gathered in lubricator are released, the mud that gases at high pressure are carried flows on vibrosieve through leak-off pipe and reclaims, mud can be prevented to be sprayed onto on offshore boring island, offshore boring island can not be polluted, workers ' health can not be injured, the mud reclaimed can recycle, can ensure that drilling well work safety carries out smoothly.
Description
Technical field
Equipment when the utility model is the grouting of oil drilling setting of casing is a kind of setting of casing grouting blowout hookup.
Background technology
After entering the sleeve pipe of certain depth under oil drilling will under pour into mud in the sleeve pipe that enters, to keep pressure balance, due under the sleeve pipe that enters interior pour into mud before be empty, be full of air, after pouring into mud, air is compressed, cover overpressure is raised, pour into mud when terminating to withdraw grout lines, pressure-air in sleeve pipe carries mud and is sprayed onto on offshore boring island, platform can be caused to pollute on the one hand, driller is not easy to work on, and the health of injury driller, makes drilling well work be affected; The mud trickled down on offshore boring island also can cause workman to slip on the other hand, and injury accident occurs.
Summary of the invention
The purpose of this utility model is a kind of setting of casing grouting of design blowout hookup, and the mud existed when overcoming the grouting of current setting of casing is sprayed onto the problem on offshore boring island, ensures that drilling well work safety carries out smoothly.
The purpose of this utility model is achieved in that a kind of setting of casing grouting blowout hookup, comprise grout lines, sleeve pipe, lubricator, pressure meter, delivery pipe, well cylinder, offshore boring island, leak-off pipe, under well cylinder is arranged on offshore boring island, in sleeve pipe lower going-into-well eye cylinder, sleeve pipe passes in stratum from the lower end of well cylinder, toroidal cavity is had between sleeve pipe and well cylinder, lubricator is connected on the top of sleeve pipe, grout lines is connected with the bottom of lubricator, the upper end of delivery pipe is connected with the top of lubricator, the junction of delivery pipe and lubricator is higher than the junction of grout lines and lubricator, the upper end setting pressure table of lubricator, delivery pipe inserts in the toroidal cavity between sleeve pipe and well cylinder, leak-off pipe is installed in the side of well cylinder.
The beneficial effects of the utility model are: open the valve on delivery pipe after setting of casing grouting terminates, the gases at high pressure be gathered in lubricator are released, the mud that gases at high pressure are carried flows on vibrosieve through leak-off pipe and reclaims, therefore, the utility model can reach goal of the invention, mud can be prevented to be sprayed onto on offshore boring island, offshore boring island can not be polluted, workers ' health can not be injured, the mud reclaimed can recycle, can ensure that drilling well work safety carries out smoothly, has significant economic benefit and social benefit.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Detailed description of the invention
Below in conjunction with Fig. 1, embodiment of the present utility model is described.
As shown in Figure 1, embodiment of the present utility model comprises grout lines 1, sleeve pipe 2, lubricator 3, pressure meter 4, delivery pipe 5, well cylinder 6, offshore boring island 7, leak-off pipe 8, well cylinder 6 is arranged on offshore boring island 7 times, in sleeve pipe 2 lower going-into-well eye cylinder 6, sleeve pipe 2 passes in stratum from the lower end of well cylinder 6, toroidal cavity is had between sleeve pipe 2 and well cylinder 6, lubricator 3 is connected on the top of sleeve pipe 2, grout lines 1 is connected with the bottom of lubricator 3, the upper end of delivery pipe 5 is connected with the top of lubricator 3, the junction of delivery pipe 5 and lubricator 3 is higher than the junction of grout lines 1 with lubricator 3, because the density of gas is lower than the density of mud, be convenient to release gas, the upper end setting pressure table 4 of lubricator 3, the pressure in lubricator can be watched, to control open flow speed work, prevent too fast bleeding off pressure from producing vibration, delivery pipe 5 inserts in the toroidal cavity between sleeve pipe 2 and well cylinder 6, leak-off pipe 8 is installed in the side of well cylinder 6.
After sleeve pipe 2 times to certain depth, be just in the milk in sleeve pipe 2 by grout lines 1, in order to prevent the gases affect in sleeve pipe 2 to be in the milk, grouting of can gradually breaking, releases gas, and then continues grouting, can make to be full of more mud in sleeve pipe 2.
After setting of casing grouting terminates, open the valve on delivery pipe 5, released by the gases at high pressure be gathered in lubricator 3, the mud that gases at high pressure are carried flows on vibrosieve through leak-off pipe 8 and is recovered, mud can not be sprayed onto on offshore boring island, can ensure that drilling well work safety carries out smoothly.
