Embodiment Construction

[0012] Examples, see attached Figure 1~4 , the main well casing 1 of the lateral well fracturing suspension completion process device is equipped with a positioning suspension packer 2, and the positioning suspension packer 2 is connected to the main wellbore staged fracturing string 4 with a pipeline 13 to the main well Horizontal position in naked eye 3. After the position is in place, the gyroscope measures the orientation, presses down on the seat hanger, throws it away, and releases the sealing tool. Connect the main wellbore fracturing inserting pipe 7 and go downhole to the back-up barrel of the positioning suspension packer 2 for fracturing construction. After the fracturing of the open hole 3 of the main well is completed, the staged fracturing pipe string 4 of the main wellbore above the upper hand is pulled out, connected to the removable re-entry skewer 5 to go downhole, and the removable re-entry skewer 5 is run downhole to the positioning suspension seal In th...

Abstract

The invention belongs to oil production process configuration of an oil field, and particularly relates to a multilateral well fracturing hanging well completion process device which comprises a sleeve (1), a positioning hanging packer (2), a main well open hole (3) and a main well staged fracturing pipe string (4). A multilateral well open hole (6) is formed in the circumference wall of the sleeve (1), wherein the upper end of the multilateral well open hole (6) is inclined, and the lower end of the multilateral well open hole (6) is horizontal. A pre-windowing surround-and-watch hanger (8) is connected on a main well hole fracturing inserting pipe (7) by utilization of a rotary pup joint (12), wherein the main well borehole fracturing inserting pipe (7) is arranged in a sleeve of the main well open hole (3). A multilateral well borehole sealing back-inserting pipe (9) is connected at the lower end of the pre-windowing surround-and-watch hanger (8), a hard axis joint (10) is arranged in the middle of the multilateral well borehole sealing back-inserting pipe (9), and a multilateral well borehole stages fracturing pipe string (11) is arranged in the horizontal section of the multilateral well borehole sealing back-inserting pipe (9). A removable heavy descending whipstock (5) is connected at the lower end of the main well borehole fracturing inserting pipe (7) in the main well sleeve (1), and the positioning hanging packer (2) is connected with the lower end of the removable heavy descending whipstock (5). According to the multilateral well fracturing hanging well completion process device, construction cost is reduced, expenses of a new well are saved and oil production of a single well is increased.

Description

technical field [0001] The invention belongs to oil field oil recovery process configuration, in particular to a branch well fracturing suspension well completion process device. Background technique [0002] At present, when opening new wells in oilfields, liner hangers are often used to connect a certain number of screens or liners for well completion operations. This kind of well completion operation is often carried out in a main well, and the oil field cannot be carried out during the well completion process. Oil recovery affects production efficiency. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned technical deficiencies, and provide a branch well fracturing suspension well completion process device that can improve production efficiency by using the main well and the branch well to recover oil simultaneously or separately. [0004] The technical solution adopted by the present invention to solve the technic...
