Description
Technical Field
The invention belongs to the field of petroleum drilling engineering, and particularly relates to a hydraulic pushing bit pointing type guiding tool.
Background
In order to meet the development requirements of exploration and development of oil and gas resources, particularly ocean oil and gas resources, drilling of special process wells such as ultra-deep wells, highly difficult directional wells, cluster wells, horizontal wells, extended reach wells, branch wells, three-dimensional complex structure wells and the like in complex oil and gas reservoirs in the later period of an oil field, and simultaneously meet the development requirements of closed-loop automatic drilling, a rotary steering drilling tool with a high build slope is urgently needed.
The rotary steering drilling technology can solve the difficult problems in the drilling technology of wells with complex structures such as extended reach wells and the like in the drilling process, reduce the development cost and achieve the purpose of increasing the petroleum yield. The rotary steerable drilling technology is one of the important bases for demonstrating the high and low level of automation technology of drilling engineering in a country or a group.
The rotary steering drilling tool is the core of a rotary steering drilling system, and is divided into four main working modes: static pushing type, static pointing type, dynamic pushing type and dynamic pointing type. The drill bit of the push-type rotary steering drilling tool has large lateral force and high build rate, but the dog leg of a borehole drilled by rotary steering is large, the track fluctuation is large, and the borehole is not smooth. The lateral force of the drill bit of the directional rotary steering downhole tool is small, the build rate is low, but the dogleg of a borehole drilled by the rotary steering is small, and the track is smooth. From the application point of view, the directional type is the development trend of the rotary guiding drilling system. Currently, the more mature rotary steerable drilling tools in foreign countries are most represented by Auto Track series of Baker Hughes, Power Drive series of Schlumberger, and Geo-Pilot series of Halliburton. The autocrack of beckhos is a typical push-type tool, and the "drive shaft-nonrotating sleeve" structure of the tool performs a guiding operation by controlling the magnitude and direction of a resultant force acting on a borehole wall by a thrust block on a nonrotating outer sleeve (see patent documents W02008101020A, US2013256034A, and the like). Typical drill point rotary steerable tools include Geo-Pilot (see patent document W02014055068A) by harebilton, revolute (see patent document W02008120025A) by wedeford, and Power Drive Xceed (see patent document N020061119A) by schlumberger. Wherein Geo-Pilot and Revolition are static directional rotary steering tools, the deflecting capability of the tool is realized by adjusting the offset displacement of the downhole steering tool, and the deflecting capability can be continuously adjusted. The Power Drive Xended of the 'full rotation' structure adopts a fixed guide biasing structure, the build-up rate of the structure is realized by a guide and steady-slope drilling mode which is changed alternately, and the control is carried out by depending on the conduction parameters (a tool face and a guide proportion) under a ground system.
Both push type and directional type have respective advantages and disadvantages, and a single mode structure cannot well meet the drilling requirement of high deflection, so that the combination of the two can effectively avoid the disadvantages of the single mode, and a mixed structure becomes the current trend. The research in this area in China is relatively late, and a high-deflecting rotary steering drilling tool which can be successfully and commercially applied is not developed yet. The dynamic directional rotary steering drilling tool and the measurement and control method thereof (No. CN 104832088B) invented by Gunn peak and the like adopt a double eccentric ring mechanism to carry out deflection, and have complex structure; the invention relates to a full-rotation directional guide tool and a guide method (an authorization notice number 104499940B) invented by Tangxue et al, and provides an improved full-rotation directional guide tool aiming at the defects of a Powerdrive Xended full-rotation directional guide tool of the Schlumberger company; "static directional rotary steerable drilling tool" (grant publication No. CN 104775757B) invented by york et al, the upper part of which is a static structure that does not rotate; the invention discloses a directional rotary steering drilling tool (No. CN 104343389B) invented by Lihongtao and the like, which adopts an integrated hydraulic cylinder to realize the offset of a mandrel so as to perform deflection, and the invention only comprises that a drill bit generates deflection in a directional way; the pushing directional rotary steering drilling device (No. CN 103437704B) of the invention adopts a connecting structure of a stabilizer and a hydraulic system, wherein the stabilizer is a non-rotating device, and only the directional part of a drill bit is used for deflecting.
