摘要
通过开展导流能力测试,明确大牛地气田马家沟组盐下储层酸压特点;基于模糊评判法,制定井层评价标准,指导后期选层;基于建立的盐下储层酸压数学模型,对目标储层的酸压施工参数进行优化,形成适应于不同类型储层的酸压工艺.经现场应用,增产率达到 20%,具有较好的推广意义.
Abstract
This article clarifies the acid fracturing characteristics of subsalt reservoir of Majiagou formation in the Daniudi gas field by conducting conductivity tests.Based on the fuzzy evaluation method,establish well layer evaluation standards to guide later layer selection.Based on the established mathematical model of acid fracturing in subsalt reservoirs,the acid fracturing construction parameters of the target reservoir were optimized to form acid fracturing processes suitable for different types of reservoirs.Through on-site application experiments,the yield increase rate has reached 20%,which has good promotional significance.
