Study on Application of Liner Downholeing Technology for Ultra-deep Wells in Fuman Oilfield
摘要
Abstract
It is crucial to ensure that the drill pipe can meet the tensile safety requirements when liner is lowered into ultra deep wells with a depth of over 7 300 m in Fuman Oilfiel dusing a combination of drill pipes and casing.The existing method for calculating the force on the combination of drill pipes and casing has a large error,which makes it difficult to meet the design and construction require-ments of the liner lowering scheme.By analyzing the forces on the pipe string combination,a calculation method for the load of the pipe string combination in the liner lowering process is established.By comparing the Landmark data,the feasibility of this calculation meth-od to the force check of drill pipe string in the early design stage of drilling engineering is verified.The result indicates that the error be-tween the load calculated using this method and Landmark simulation result is less than 5％.The proposed calculation method for load of the pipe string combination in the liner lowering process has important guiding significance for the calculation of the load of drill string combination in the early design and mid-term on-site construction of ultra deep well drilling engineering.The proposed plan using steel drill rods of larger size and composite drill strings of various materials and specifications in lowering liner into ultra deep wells can provide support for drilling engineering of ultra-deep oil and gas reservoirs.关键词
