Based decision-making model to optimize perforating parameters in oil and gas wells
In this study,perforating parameters were discussed to increase both productivity and economic benefits in oil and gas wells.And an evaluation index system with multiple attributes,including casing safety as well as perforating bore parameters and skin coefficient in perforating channel,was proposed after analyzing physical mechanisms and their con-trols on the perforation.And then the parameter impact on both safety and efficiency was fully accessed.Additionally,a de-cision-making model was set up on the basis of one Technique for Order Preference by Similarity to Ideal Solution(TOP-SIS)to optimize the parameters.It can effectively calculate individual parameter's weight,put them in order,and find out the best parameter combination.Results show that(i)the proposed TOPSIS-based model can optimize perforating parame-ters and improve perforating efficiency;(ii)it ensures the wells in safe operation and reduces operational risks;and(iii)its application significantly raises economic benefits.All above results prove this model's availability and superiority.Com-pared with empirical and traditional well-testing methods,this model provides more assists in scientific decision-making.In conclusion,the research results suppose a new scientific decision-making methodology to optimize perforating parame-ters,which is helpful to guide practical perforation,optimize completion,advance production performance,and offer theoret-ical support and actual guidance for benefit increase.
