塔里木盆地塔中地区深埋白云岩储层特征及综合预测研究
|
摘要
塔里木盆地寒武系-下奥陶统的白云岩地层厚度大、分布广,具有多套储盖组合,基质孔隙、次生孔洞和裂缝都十分发育,是非常有利的油气勘探接替领域。但由于白云岩埋藏深、勘探程度低,尚未形成成熟的储层预测技术系列。通过对灰岩和白云岩储层的地质、岩石物理和地震响应特征进行对比分析,将在灰岩储层预测中应用较好的技术应用到白云岩储层预测中。在寒武系白云岩岩石物理特征研究的基础上,进行叠前储层预测,并探讨不同地层储层展布的控制因素,对塔里木盆地白云岩勘探领域的深入研究具有一定的指导意义。
The dolomite strata from lower Ordovician to Cambrian in Tarim Basin were thick and wide distribution,moreover,it had multiple sets of combinations of source rock,reservoir and cap-rock.Additionally,the matrix and secondary pores,and fractures were well developed,which was the beneficial area for hydrocarbon exploration.However,as the dolomite was deeply buried,current exploration was on a low level and maturity prediction technology was not yet formed.In this paper,by comparing and analyzing the geology,rock physics and seismic response characterizations of limestone and dolomite reservoirs,better technologies for limestone reservoir prediction are applied to dolomite reservoir prediction.The pre-stack reservoir prediction is performed based on the study of rock physics in the dolomite reservoir in Cambrian,the controlling factor of reservoirs in different strata are discussed.The research provides guidance for further study of dolomite reservoir exploration in Tarim Basin.
