摘要： 基于数据包络分析法(断据包络分析法)原理,对广安须家河组气藏广安2 区块的单井产量进行了评价。利用断据包络分析法模型对气井进行横向比较,预测了各个气井静储量、动储量和产量的潜力,并分析了断据包络分析法有效性和实际气井之间的关系。结果表明:断据包络分析法有效井基本上都是高产井,静储量潜力比较大的井多是中产井,动储量潜力比较大的井多是低产井,产量潜力大的井在动静储量方面均有潜力。据广安气田须六段气井的产能状况分析,多数气井经过加砂压裂后均获得较高的天然气产能。

Abstract: Based on the principle and model of data envelope analysis (DEA), the single well production in Guang'an Block 2 of Xujiahe gas reservoir in Sichuan basin is evaluated, including the interwell lateral comparison, the static-dynamic reserves and production potentials prediction of each gas well, the effectiveness of DEA and the relations among gas wells. The results indicate that the DEAeffective wells are basically high-yielding wells; the wells with large potentials of static reserves are mostly mid-yielding wells; the wells with large potentials of dynamic reserves are mostly low-yielding wells; the wells with big production potentials are all of potentials in static and dynamic reserves. According to the productivity analysis of gas well of Xu-6 member in Guang'an gas field, most gas wells can be of higher tested gas productivity after sand fracturing.
