Down-hole liquid driving energy-gathered drilling tool and using method

Abstract

The invention provides a down-hole liquid driving energy-gathered drilling tool and a using method. The invention aims at acquiring a high-performance down-hole liquid drive drilling tool which can meet drilling well condition requirements of an ultra-deep high-temperature well. According to the down-hole liquid drive energy-gathered drilling tool and the using method, a high-integrated steel modular structure is matched with a working rotor with a special-shaped spiral groove, so that continuous dynamic distribution pressure build-up and leakage flow rotation working operating condition can be automatically achieved, and due to the fact that composite sealing and lubricating rings machined with steel and high-performance materials are adopted for main workpieces, the main workpieces are extremely excellent in both high temperature resistance and wear resistance; meanwhile the drilling tool is provided with corresponding designs of multiple specifications and models so that the drilling tool can well achieve connection with petroleum pipe thread buckles, of different sizes, which execute an API standard and has good market prospects and generalization and popularization values.

Description

technical field [0001] The invention belongs to the field of underground energy exploitation, and relates to an energy-gathering drilling tool driven by downhole fluid and a use method thereof. Background technique [0002] The exploitation of underground energy requires the help of drilling equipment to drill to the target development layer. In the early days, due to the restriction of drilling supporting technology, only vertical wells with low productivity can be drilled. With the rapid development of drilling technology, foreign countries have developed downhole fluid Driven drilling tools, combined with advanced drilling-while-drilling steering instruments, can drill highly targeted, high-yield directional wells and directional horizontal wells with higher productivity. If a downhole fluid-driven drilling tool with better performance can be developed, it will be It can satisfy the drilling operation of ultra-deep wells in the future, and can even truly provide comprehen...

Problems solved by technology

However, the existing domestic research only focuses on how to improve the high temperature resistance and wear resistance of rubber parts and supporting bearings. The research on how to carry out bold innovation in terms of principle, structure and application of new materials still needs to be done. Very little done, no public reports
