塔里木盆地巴楚隆起南侧的和田河气田是在玛扎塔格构造上发现的典型背斜型气藏。由于该区钻井主要集中在构造核部，钻井深度相对较浅，而构造两翼的地震资料品质较差，因而对该构造出现了多种解释结果。本文依据钻井资料标定，应用断层相关褶皱理论，对该区二维地震剖面测网重新进行详细构造解释。结果表明，玛扎塔格构造主要构造样式为以中寒武统膏岩为滑脱面的滑脱背斜，玛4井东构造样式则为断层扩展褶皱，表明玛4井东存在近南北走向的横向走滑断层，并在地震剖面上得到证实。地震解释结果也证实了玛扎塔格构造西北侧发育的古董山逆冲断层向南东方向延伸进入和田河气田。滑脱褶皱背斜南北两翼发育的中新世－上新世生长地层和第四系角度不整合，表明该构造主要形成时期为中新世—上新世，而且第四纪该构造又重新活动。

The Hetianhe gas field is one of the typical anticline gas reservoirs found in Mazatage structural belt of southern Bachu uplift in Tarim Basin.Previous exploration drilling is focused on core of the structure and the depths of exploratory wells are relatively shallow.Moreover,the quality of seismic data acquired on the flanks is poor.Therefore,structural in-terpretation was high in uncertainty.This paper tried to reinterpret the 2D seismic data based on calibration with drilling data and application of faulting-related fold theory.The result shows that the Mazatage structure is dominated by detach-ment anticline with the Middle Cambrian gypsum as detachment surface,while the part in the east of well Ma-4 in the structure is a fault-propagation fold,indicating the existence of a near NS-trending transverse strike-slip fault( seismic pro-file also revealed the same conclusion) .Seismic interpretation also indicates that a thrust fault named Gudongshan deve-loped on the northwest flank of the structure extends into the Hetianhe gas field.The Miocene-Pliocene growth strata and Quaternary angular unconformity developed on the south and north flanks in the detached anticline show that the structure was probably formed during the Miocene-Pliocene period and reactivated during the Quaternary.
