Evaluating gathering-transportation process in tight gas fields based on multilevel and grey correlation analysis
摘要
Abstract
Most gathering-transportation projects in tight gas fields feature high investment,long construction period and numerous influencing factors.Their objective evaluation is related to the overall field development and construction.So,YQ2-Y128 well area was taken as an example to analyze both advantages and disadvantages of three gathering-transportation processes under high,medium and low pressure.Based on analytic hierarchy process(AHP),an evaluation system was established to select three first-grade evalu-ation indexes(production safety,process technology and economic benefits)and ten second-grade ones(throttle failure,liquid accu-mulation,pipe network pressure loss,gas-gathering radius,operating pressure,land acquisition,metering error,internal rate of return,investment,and operating costs).In addition,the weight was determined for each index by using AHP,and the method of grey cor-relation analysis(GCA)was adopted to evaluate these three processes.Results show that(i)the determined indexes rank in an order of descending weight,namely internal rate of return,investment,throttle failure,pressure loss,operating cost,gas-gathering radius,liquid accumulation,operating pressure,land acquisition,and metering error;and(ii)the obtained weight from AHP is introduced into GCA to determine the grey correlation for these processes one by one.As a result,it is determined that,as the optimal one,the gather-ing-transportation process under medium pressure enjoys the highest correlation.The research results can provide an evaluation means and reference for the objective comparison and decision of gathering-transportation processes in tight gas fields at home and abroad.关键词
