Problems solved by technology
Due to the limitation of time and energy, the number of historical wells referred to in the design of each well is extremely limited, and the knowledge rules hidden in the historical well data are difficult to be fully excavated and integrated by the designers, so it is impossible to do wells in a short time. Optimized drilling engineering plan

A method and system for intelligently recommending a drilling plan, wherein the method includes: step 1, obtaining geological data to be drilled; step 2, generating a geological feature vector of a formation to be drilled according to the geological data to be drilled; The geological feature vector of the formation is matched with the geological feature vector set of preset historical wells, and the first recommended drilling case set is determined from the preset drilling case set according to the matching results, so as to obtain the drilling plan of the formation to be drilled, wherein the preset historical well The geological feature vectors of historical wells in the geological feature vector set and the historical drilling cases in the preset drilling case set are divided according to formation intervals and correspond to each other. Compared with the prior art, the method can automatically apply objectively existing but implicit drilling knowledge and rules to new drilling, so as to achieve the purpose of optimizing drilling.
Description
technical field [0001] The invention relates to the technical field of oil and gas exploration and development, in particular to an intelligent recommendation method and system for a drilling plan. Background technique [0002] The function of drilling engineering is to build oil and gas channels from underground reservoirs to the surface and to collect formation information. High input, high output, high risk and high technology are the characteristics of contemporary oil and gas drilling engineering. The "high-tech" characteristics of drilling are informatization, intelligence and integration. With the deepening of exploration and development, the remaining domestic oil and gas resources are mainly concentrated in low-permeability and low-abundance, deep, complex formations and deep-water areas of the ocean. Therefore, drilling projects are faced with four difficulties: "low, deep, difficult, and sea". Drilling geological objects are complex, and the engineering difficult...
