Background
At present, a 30-50 m guide pipe is generally arranged on the surface layer to seal off a loose earth layer on the earth surface before formal drilling of oil drilling, and the guide pipe is arranged on site mainly by two modes: firstly, carry out the cement from the ground with the pipe is direct to pound into the back manual work and fill, secondly at first use the drill bit to bore to reach the design depth, then the downcomer well cementation, the first kind of mode reliability is lower to well head correction to digging the brill brings a lot of inconveniences, and the second kind is though the reliability is higher, nevertheless creeps into the in-process because can't install the anti-overflow pipe, and the general way is predetermine culvert flow to mud pit, or adopts the electric pump to swamp to the circulation jar.
Pre-designed culverts are prone to build-up of debris within the channels causing blockages and are limited in displacement and drilling rate. The electric pump is adopted for pumping, the limitation exists, if the surface clay slurrying performance is good, the returned rock debris agglomeration is easily caused to block an outlet pipe, the circulating chip removal is not smooth, the shutdown is caused, particularly in the cluster well group drilling process, a drilling machine pushes a drilling machine to continuously construct a plurality of well positions, when the lengthened outlet pipe is used, the length reaches 35-40 meters, the rock debris flocculation deposition is easily caused due to the influence of the length increase and the too small discharge capacity, and the blocking fault with the larger processing difficulty is formed after a plurality of serious agglomeration positions.
Chinese patent publication No. 108894740a, published as 2018, 11 and 27, discloses a device and a method for cleaning rock debris during deep water surface drilling, and the device for cleaning rock debris during deep water surface drilling comprises: the opening cylinder is provided with an opening through groove which is axially arranged; the chip sweeping mechanisms are connected to the opening cylinder body at intervals along the circumferential direction of the opening cylinder body; wherein, sweep bits mechanism has: the fixed block is connected to the outer wall of the opening cylinder; one end of the chip sweeping leg is rotatably connected to the fixed block, and the other end of the chip sweeping leg is provided with a chip sweeping vane wheel; one end of the pull rod is positioned above the fixed block and connected to the outer wall of the opening cylinder, and the other end of the pull rod is movably connected to the chip sweeping leg. The device can clean a large amount of rock debris accumulated around the submarine surface conduit while drilling in the deepwater surface, and can continuously work in the deepwater drilling process without frequently tripping the drill midway to adjust the position of the device for cleaning the rock debris in the deepwater surface drilling.
However, in the conventional techniques represented by the above patent documents, the circulation of the cuttings during the surface layer pipe drilling process is still not achieved. Particularly, in the process of drilling a cluster well group, a drilling machine pushes a drilling machine to continuously construct a plurality of well positions, when an extended outlet pipe is used, the length reaches 35-40 meters, rock debris is easy to flocculate and deposit due to the influence of increased length and excessively small discharge capacity, and a blockage fault with higher treatment difficulty is formed after a plurality of serious parts are caked. However, the conventional techniques represented by the above patent documents still have a problem of clogging the elongated outlet pipe.
