Abstract

The invention discloses a mechanical drilling speed determination method and device, a drilling parameter optimization method and device and electronic equipment, and relates to the technical field of petroleum and natural gas drilling, and the mechanical drilling speed determination method comprises the steps that parameter values of a plurality of drilling parameters in a target work area are obtained; the parameter values of the multiple drilling parameters are substituted into a mechanical drilling speed equation, and a first mechanical drilling speed is obtained through calculation; substituting the parameter values of the plurality of drilling parameters into a preset prediction model to predict a drilling speed error; and correcting the first mechanical drilling speed through the drilling speed error to obtain a second mechanical drilling speed, and taking the second mechanical drilling speed as a target mechanical drilling speed. According to the mechanical drilling speed determination method, the influence of the drilling parameters which are not mentioned in the mechanical drilling speed equation on the mechanical drilling speed can be made up, the error value between the calculation result of the mechanical drilling speed equation and the actual mechanical drilling speed can also be made up, and the finally determined mechanical drilling speed is high in precision and accuracy; the drilling parameter optimization method based on the mechanical drilling speed determination method is also high in accuracy.

Description

technical field [0001] The present application relates to the technical field of oil and gas drilling, in particular to methods, devices and electronic equipment for determining the rate of penetration and optimizing drilling parameters. Background technique [0002] ROP refers to the length of drilling per unit time (that is, unit footage). ROP is affected by various drilling factors, such as weight on bit, rotational speed, formation conditions, etc. Drilling parameter optimization refers to studying the influence of controllable drilling conditions on the ROP under the objective conditions of the target work area, and determining the value of each controllable parameter that can make the objective function obtain the maximum value. In the process of drilling parameter optimization, the prediction accuracy of ROP is very important. [0003] The existing ROP prediction method is based on the ROP equation established by introducing a small amount of drilling parameters, ba...
