摘要

基于构造、断裂演化、岩心、测井、地震、钻录井、生产动态等资料分析,对塔里木盆地哈拉哈塘油田塔河南岸地区跃满区块奥陶系断溶体油气藏的储集空间特征、展布形态、成因进行系统研究,并结合开发实践,对断溶体油气藏的成藏与油气富集进行系统分析。研究结果表明,断溶体油气藏以"体"的形式呈不连续、非均质、不规则性分布,其形成主要受控于断裂的发育程度,建立沿主干深大通源断裂溶蚀、沿次级通源断裂溶蚀和沿次级内幕断裂溶蚀3种断溶体油气藏形成模式;断溶体油气富集受控于成藏期与断裂活动时空上的匹配关系、断裂的级别和断裂的分段性质。研究结果可有效指导哈拉哈塘油田塔河南岸地区奥陶系碳酸盐岩井位部署,实现断溶体油气藏高效开发。图9表2参25

Abstract

Based on comprehensive analysis of tectonic and fault evolution, core, well logging, seismic, drilling, and production data, the reservoir space characteristic, distribution, origin of fault-karst carbonate reservoir in Yueman block of South Tahe area, Halahatang oilfield, Tarim Basin, were studied systematically. And the regular pattern of hydrocarbon accumulation and enrichment was analyzed systematically based on development practice of the reservoirs. The results show that fault-karst carbonate reservoirs are distributed in the form of "body by body" discontinuously, heterogeneously and irregularly, which are controlled by the development of faults. Three formation models of fault-karst carbonate reservoirs, namely, the models controlled by deep major connecting oil source fault, secondary connecting oil source fault and secondary fault inside formation, are built. The hydrocarbon accumulation and enrichment of fault-karst carbonate reservoirs is controlled by the spatiotemporal matching relation between hydrocarbon generation period and fault activity, and the size and segmentation of fault. The study results can effectively guide the well deployment in Ordovician carbonate reservoir of South Tahe area, Halahatang oilfield and help the efficient development of fault-karst carbonate reservoirs.

Key words： Tarim Basin; Halahatang oilfield; South Tahe area; Ordovician; fault-karst; carbonate reservoir; hydrocarbon accumulation; oil-gas enrichment
