【摘要】:针对长岭气田登娄库组气藏地质条件复杂、开发难度大等特点,首先通过地质特征再认识及富集区优选研究,应用地质、地震、气藏工程等多学科的综合研究,最终形成一套适合长岭气田登娄库组气藏水平井整体开发及效果评价技术,实现登娄库组各主力层系水平井高效开发方式。本文通过对登娄库组气藏地质特征再认识研究,为优化井位部署提供了依据。应用不断丰富的钻、录、测资料,精细刻画储层展布规律,明确Ⅲ、Ⅳ砂组整体含气,优质储层主要集中在构造主体区域,为水平井主要目的层。通过应用叠前AVO含气性烃检测及多条件约束气藏地质建模技术,分析外围含气性及一、二砂组富集区分布规律。开展以经济效益为终极目标,评价登娄库组气藏水平井开发的适应性,确立水平井多段压裂开发方式,形成了水平井优化部署设计技术。通过水平井现场实施,细化导向流程,形成水平井现场实施技术。针对深层致密气藏建立水平井评价指标体系,形成水平井开发效果评价技术。最终明确了长岭气田登娄库组气藏整体开发方案,即采用直井+水平井开发,共设计气井60口井,其中利用已钻老井15口,含4口直井,新钻生产井45口(均为水平井),形成天然气8.0亿方年产能力,采气速度2.7%,稳产年限为8年,实现长岭登娄库组气藏整体高效开发。
[Abstract]:In view of the complex geological conditions and difficult development of the gas reservoirs in the Denglouku formation of Changling gas field, firstly, through the recognition of the geological characteristics and the optimal selection of rich areas, the comprehensive research on applied geology, earthquake, gas reservoir engineering and so on is made. Finally, a set of techniques suitable for the overall development and evaluation of horizontal wells of gas reservoirs in Denglooku formation of Changling gas field were formed to realize the efficient development of horizontal wells in each main formation of Denglooku formation. In this paper, the geological characteristics of gas reservoirs in Denglooku formation are studied again, which provides the basis for optimizing well location deployment. The application of abundant drilling, recording, logging data, fine description of the distribution of the reservoir, the determination of the 鈪,
