摘    要:塔河油田的发现首先得益于三维地震勘探技术的应用,在进一步的评价和滚动勘探开发过程中,针对古生界岩溶型碳酸盐岩储层的非均质性,利用三维地震资料、使用各种地球物理方法开展了储层预测,来研究储层展布和含油气性;在井筒中应用负压钻井技术,在保证能正常钻井施工、提高施工效率的同时,最大限度地降低了油层的污染,也保证了油气层的及时发现;使用成象测井技术,对碳酸盐岩的孔、洞、缝的发育、渗透层段的侧向延展、连通情况以及地层流体类型进行研究,进而综合各种测井资料定量计算地层岩性及物性、含油性参数;压裂酸化工艺的成功应用,有效解除了油气层段地层人为造成的伤害,并且通过人工压开酸蚀新裂缝,达到连通天然孔洞缝、提高导流能力、恢复产能、解放油层的目的。除此之外,与这些主要技术配套的相关技术的使用,都对塔河油田的勘探评价起了有效的保证作用。

关 键 词:三维地震勘探   储层预测   负压钻井   成象测井   压裂酸化   碳酸盐岩   塔河油田   塔里木盆地

Abstract:The discovery of Tahe oilfield first benifits from the application of the 3 D seismic exploration techno logy.In the course of further evaluation and rolling exploration and development and aimed at the heterogeneity of the Paleozoic karst type carbonate rock reservoirs,3 D seismic data and various geophysical methods are used to make reservoir prediction and study the distribution and hydrocarbon prospects of reservoirs.While the negative pressure drilling technology when applied to shafts can guarantee normal drilling operation and raise working efficiency,it reduces the pollution of reservoirs to a minimum and ensures to discover hydrocarbon reservoirs withous delay.The imaging logging technology can be used to study the development of pores,caves and fissures in carbonate rocks,the lateral extension and connection of permeable layers and the types of formation fluid;furthermore,the lithology of strata and the parameters for physical properties and petroliferous features can be calculated quantitatively by combining various logging data.The successful application of the fracturing acidization technique effectively removes man made injuries to reservoirs.And by artificial fracturing acid corroded new fissures,it connects natural pores,caves and fissures,raises diversion capacity,regains productive ability and libe rates oil reservoirs.Besides,the use of related technologies of these major ones plays an effective guarantee role in the exploration evaluation of Tahe oilfield.
Keywords:3-D seismic exploration  reservoir prediction  negative pressure drilling  imaging logging  fracturing acidization  carbonate rocks  Tahe oilfield  the Tarim Basin
