Rcsearch On Comprehensive Evaluation Of Gas Well Production Technology In Jingbian Gas Field

Jingbian gas field belongs to "low porosity, low permeability, low abundance" three low field, at the initial stage of development needs to take fracturing and acidizing reservoir reform measures, the need to improve the productivity and recovery application of drainage gas recovery technology in recovering. Incremental measures after all is a large investment, short period, high risk project, pre work must be scientific, rigorous evaluation, according to the actual situation, choose optimal technical scheme, improve the success rate of increase production measures, so as to achieve better stimulation effect.This paper presents the concept of comprehensive evaluation of production technology of natural gas, and regulate the principle and program evaluation, mainly for the early development of reservoir reconstruction and exploitation of water drainage and gas production measures, comprehensive evaluation. Stimulation of reservoir reconstruction, a set of three factors, including geological technology, economy evaluation index system, and applies TOPSIS method of comprehensive evaluation, quantitative evaluation, the ranking scheme. Comparative analysis of gas stimulation drainage technology, from the technical feasibility and economic rationality to identify two areas of the related factors affecting the drainage gas recovery technology in comprehensive evaluation, and the evaluation index system is established; and using the improved C2R model of DEA method in comprehensive evaluation, exclude the interference of artificial factors, the quantitative analysis, according to the evaluation results, analysis the reason of ineffective quality and non effective technology, provides the scientific basis for production decision.Therefore, study of Jingbian gas field production stimulation technology comprehensive evaluation can help to make decision scientifically; help prolong the gas field exploitation period and increase the economic rational use of resources to achieve economic efficient; Jingbian gas field development has pushed some.
