Archaeozoic buried-hill reservoir of Bozhong 19-6 condensate field: Main controlling factors and development model
-
摘要:
综合运用岩心、测井、地震、野外露头及生产测试资料对渤中19-6太古宇潜山储层发育特征及主控因素进行了分析。研究发现渤中19-6太古宇潜山储层主要受岩石类型、构造运动和风化淋滤等因素影响，储层纵向分为风化带和内幕带，其储层发育主控因素及储层空间分布模式差异明显。其中，风化带受构造和风化淋滤作用双重控制，发育构造缝、风化缝、溶蚀孔隙等储集空间类型，裂缝整体发育呈网状，储层连通性好。受宏观古地貌控制，风化带厚度从古构造高部位向构造低部位呈逐渐减薄的“似层状”分布模式。同时，受岩石类型、局部断层、沟-脊微地貌以及坡度等因素的影响，风化带厚度局部增厚或减薄。潜山内幕带主要受内幕高角度断层控制，基本不受风化作用影响，储集空间以构造缝为主。通过内幕高角度断层的识别和刻画，认为内幕带储层沿高角度断层带状、漏斗型分布。上述认识对于渤中19-6凝析气田开发方案的编制，特别是为潜山储量动用及注采井网部署奠定了重要基础。
Abstract:In order to reveal the distribution pattern of the Archaeozoic buried hill reservoirs in the Bozhong 19-6 condensate field, integrated study is carried out with cores, well logs, well testing data, seismic data in addition to outcrops. The Archaeozoic buried hill reservoir consists of weathered crust reservoirs and internal rock reservoirs, which have obvious differences in controlling factors and distribution patterns. The formation of weathered crust reservoir mainly depends upon structural deformation and weathering, of which the thickness is dependent on the ancient landform. It usually becomes thinner from the paleosrtuctural high to the structural low. Rock types, local faults, microreliefs and topographic slopes are also the controlling factors needed to be considered. However, the inner part reservoir is mainly controlled by the high-angle faults, and the main reservoir space is provided by structural fractures.
