摘要/Abstract

摘要：

超深层断控缝洞型油藏典型特征为深大断裂控储控藏，在多期构造成藏和古岩溶作用影响下，储集层非均质性强，应力敏感性强，油田开发过程中井间连通关系不明确，井间连通模式复杂，极大地影响着油井间注水、注气开发效果。作为指导碳酸盐岩断控缝洞型油藏注水开发的基础工作，油藏井间连通情况的判断至关重要。提出多源数据融合的动态-静态协同分析方法，以静态连通单元划分结果为基础，根据生产动态资料和压力数据，综合运用开井静压分析、类干扰分析、生产特征相似性等方法，结合试井响应结果，对研究区静态连通单元的动态连通性进行判断，并对其变化进行分析，克服了传统井间连通性分析存在的多源数据融合不足及开发数据低效性的问题。

Abstract:

Ultra-deep fault-controlled fractured-vuggy reservoirs are typically characterized by deep and large fault-controlled hydrocarbon accumulation and preservation. Under the influence of multi-stage tectonism and paleokarstification, the reservoirs have strong heterogeneity and stress sensitivity, leading to unclear inter-well connectivity during the oilfield development process and complex inter-well connection modes, which greatly affect the performance of water/gas injection in production wells. As a fundamental task guiding the waterflooding development of fault-controlled fractured-vuggy carbonate reservoirs, the judgment of the inter-well connectivity is of vital significance. This paper proposes a dynamic-static collaborative analysis method by multi-source data fusion. Based on the division results of statically connected units, using the production performance data and pressure data, several methods such as static pressure analysis, quasi-interference analysis, and production feature similarity, are combined with the well test responses to judge the dynamic connectivity of the statically connected units in the study area. Meanwhile, the changes in the connectivity are analyzed. The proposed method gets ride of the problems of insufficient multi-source data fusion and low efficiency of development data existing in conventional inter-well connectivity analysis.

Key words: Shunbei No.1 fault zone, ultra-deep stratum, fault-controlled reservoir, inter-well connectivity, quasi-interference analysis, production performance similarity
