摘    要:鄂尔多斯盆地苏里格气田储集层具有低渗、强非均质性、中强压敏的特点,气井产能低,稳产期短。根据单井模拟及生产动态分析,气井低产量生产可以降低压敏效应的影响,加强气井低产量生产阶段的管理,有利于合理利用地层能量,提高井控外围低渗区储量动用程度;分层压裂、多层合采可以在纵向上充分动用气井控制储量,增加气井最终累计产气量和稳产时间;地质研究与地震相结合,是提高储集层预测精度和钻井成功率的技术关键;降低成本,争取优惠政策也是提高经济效益的有效途径。

关 键 词:低渗气田  非均质性  压敏  储集层预测  分层压裂  合理配产  降低成本

Abstract:The Sulige gas field in the Ordos Basin is characterized by low permeability, strong heterogeneity and middle-to-high pressure-sensitivity, and the gas wells have low productivity and a short stable production period. The single well simulations and production performance analysis reveal that producing with low daily output can reduce the effect of rock pressure-sensitivity, and that strengthening the management during the period of low production will help to utilize the formation energy rationally and to improve the working state of the reserves distributing in the low permeability area beyond the well drainage. Separate layer fracturing and commingling production can make the most of the controlled reserves in vertical, increase the final cumulative gas production and extend the stable production period. Integrating geological research with seismic interpretation is the key technology for improving the precision of the reservoir forecast and the ratio of successful drilling. Cost-cutting and striving for preferential policies are also effective ways to enhance the economic return.
Keywords:low permeability gas field  heterogeneity  pressure-sensitivity  reservoir prediction  separate layer fracturing  rational proration  cost-cutting
