高青油田孔店组火成岩储层特征研究
|
摘要
高青油田位于东营凹陷构造带西南部,构造复杂,火成岩储集体规模大、厚度变化大,且岩性致密,纵向上主要分布在孔店组。以工作站技术为依托,建立了一套火成岩储集体综合解释技术,包括地层精细对比、层位确定、构造精细解释和综合解释、取心井岩、电解释、火成岩相带划分与评价。由于火成岩具有极强的非均质性,对其识别与预测是油气勘探的难题之一,首次综合使用地震分析、测井约束反演、取心井岩心与电测曲线分析等技术和方法,有效地识别了高青油田火成岩储集体,并根据火成岩喷发期次,将高青油田孔店组火成岩储集体分为1、2、3、4期。在岩心观察及分析化验资料研究基础上,依据喷发岩的岩性、构造特征、厚度变化及电性、储集空间发育程度的差异等,将火成岩分为火山口相、近火山斜坡相及远火山斜坡相三个相带[1]。在储层及油气成藏地质条件分析研究基础上,依据圈闭钻井控制程度,分控制储量和预测含量对油气资源量进行了评价,为火成岩油气藏的有效开发提供了理论依据和技术方法。
Gaoqing oilfield, which is characterized by complicated structures, is located on the southwestern part of Dongying sag structural belt. The igneous rock reservoir mainly distributed in Kongdian formation by vertical is large in size, with variable thickness and compact lithology. A set of comprehensive interpretation techniques dominated by seismic data processing technique on work station and interactive technique are established, including fine formation correlation, formation identification, sophisticated structural interpretation and comprehensive interpretation, core well lithology, electric log interpretation, igneous facies division and evaluation. Identification and forecasting for igneous rock is one hard problem of exploration activity, because it has extreme aeolotropism. By firstly synthetically utilizing seismic analysis, well logging restricted inversion, core well core and electric log analysis method and so on, the igneous rock reservoir of Gaoqing oilfield is effectively identified and divided into one to four four phases according to igneous rock erupting phase. On the base of core observation and analysis and laboratory test data research and in the light of lithology of eruptive rock, tectonic feature, variable thickness ,the difference of electric nature and reservoir space vegetal degree etc, the igneous rock divided into crater facies, proximal slope facies and distal slope facies. As a foundation of reservoir and the geologic condition of forming hydrocarbon reservoir research and in the light of control degree of trap well drilling , sub-control reserves and predicting content, hydrocarbon resources is evaluated, what provides theory foundation and technique method for igneous rock reservoir valid development.
