摘要： 苏里格气田地质条件复杂，需要开展大井组部署有利区筛选及部署方式关键技术研究，确保大井组开发效果，以实现苏里格气田降本增效、长期稳产的目标。针对苏里格气田古生界不同类型气藏有效储层分布特征，通过地震地质综合研究，形成了致密砂岩储层基于地质知识库的目标+多点地质统计学的三维地质建模技术及基于低渗透碳酸盐岩气藏二元运聚成藏模式的有利区筛选技术，并确定了大井组部署区域；同时，通过井网优化、井型优选及大井组部署思路，确定了大井组部署模式，提高了多层系储层储量动用及气田采收率。大井组开发关键技术在苏里格气田的成功应用，有效地解决了地质、地震及地面有机结合的技术难题，提高了气田开发效益，实现了低成本高效开发。

Abstract: Aiming at the complex geological conditions of Sulige gasfield, the key technology study on the favorable area selection and deployment mode of large well group is required to guarantee the development effects of large well group. According to the distribution characteristics of effective reservoirs in different Upper and Lower Paleozoic gas reservoirs of the Sulige gasfield, the comprehensive research on seismic geology was conducted to create the three-dimensional geologic modeling technique based on "geological database target and multipoint geological statistics" as well as the Lower Paleozoic favorable area selection technology based on "binary migration and accumulation mode of low-permeability carbonate gas reservoirs" in tight sandstone reservoirs, so as to confirm the deployment areas of large well group. Meanwhile, through well pattern optimization, well type selection and the establishment of deployment ideas for large well group, the deployment mode of large well group was determined to enhance the reserve utilization of multi-layer reservoirs and gas field recovery ratio. The key development technology of large well group has been successfully applied in Sulige gasfield, which can effectively solve the technical issues in the organic combination among geology, seismic and ground, and further improve gasfield exploitation efficiency and achieve the high efficient development with low cost.

Key words: Sulige gasfield, cost-saving and benefit-increasing, fine description of reservoir, favorable zones prediction, stereoscopic development technology of great well group, well type combination
