摘　　要：塔里木盆地塔中奥陶系多发育碳酸盐岩缝洞体储层,在水平井开发过程中为提高单井产量,常以连续钻遇多个缝洞单元的开发方式为主。但由于碳酸盐岩缝洞体储层空间及孔隙结构的多样性,导致地层非均质性强,串珠相对独立。受裂缝、压实作用影响,碳酸盐岩储层的串珠水平井可能存在多套不同压力体系,现场开发难度大,关井强钻技术为碳酸盐岩多压力体系储层开发提供了新的思路。通过对ZGXX-H9井关井强钻技术应用的说明,阐述了其在多压力体系缝洞体储层开发过程中的可行性,为类似储层的开发提供了借鉴。There are many carbonate fracture-cavern reservoirs in Tazhong Ordovician of Tarim Basin.In order to improve the production of a single well,continuous drilling of multiple fracture-cavern units is the main development method in the process of horizontal well development.However,due to the diversity of carbonate reservoir space and pore structure,the formation is highly heterogeneous and the beads are relatively independent.Affected by fracture and compaction,there may be multiple sets of different pressure systems in bed-string horizontal wells of carbonate rock reservoir,which are difficult to develop in the field.However,the closein and strong drilling technology provides a new idea for the development of carbonate rock reservoir with multiple pressure systems.Through the description of the application of shut-in and strong drilling technology in ZGXX-H9 well,the feasibility of its application in the development process of fractured cave-body reservoirs with multiple pressure systems is expounded,which provides reference for the development of similar reservoirs.
