摘要

基于大量地质、地球物理资料,从断裂特征和地层厚度分析入手,探讨塔河地区奥陶系岩溶斜坡上峰丘高地的成因,并对其缝洞类型与油气分布进行深入剖析。结果表明,海西早期,岩溶斜坡上发育由高耸丘峰与狭长丘谷组成的带状峰丘高地,其与北北东向正花状构造空间展布一致,具继承性演化特征。峰丘高地奥陶系鹰山组残余厚度大于其间残丘谷地,断层-裂缝及缝洞复合体密集发育,厚度可达百米,60%的油井单井累计产油量可达20×104 t,在其丘谷处发现崩塌角砾无序堆积搭建“洞穴”,洞高为1.6~13.5 m,充填率为51.6%。研究认为,走滑挤压背景下的正花状构造形成了岩溶斜坡上峰丘高地的雏形,导致了水系差异分布和岩溶作用差异;相对于富水残丘谷地,贫水的峰丘高地岩溶作用弱,残余地层厚,地貌相对抬高;每逢雨季,大气降水沿其中密集分布的缝隙扩散、渗滤溶蚀,形成错综复杂的网络状缝洞群;加之岩溶斜坡继承性隆升以及北北东向通源断裂的有效配置,油气持续不断向缝洞空间充注、运聚,形成纵向准连续分布、横向片状富集的峰丘体型缝洞油藏,油气丰度大,油井产量高。图11参28

Abstract

Based on a large number of geological and geophysical data, the formation, fracture-caves types and hydrocarbon distribution of hoodoo-upland on the Ordovician karst slope in the Tahe area, Tarim Basin, are discussed by analyzing faults and strata thickness. The hoodoo-upland was made of high peaks and narrow valleys in the Ordovician karst slope during the Early Hercynian karst period, which were distributed along the NNE positive flower structure and had inherited evolution. The fault-fractures and fracture-vugs complex were extremely developed, with a thickness of 100 m. The cumulative oil production of 60% oil wells was more than 20×104 t per well in the hoodoo-upland, where the residual thickness of the Ordovician Yingshan Formation was greater than karst depressions. Caves formed by the shelter of collapsed breccias were developed in the valleys. They were 1.6 to 13.5 m high, with a filling rate of 51.6%. The positive flower structure under the settings of strike-slip compression controlled the early formation of the hoodoo-upland on the karst slope, resulting in the differences of drainage distribution and karstification. Compared with the water-rich karst valley, the hoodoo-upland with lean water suffered weaker karstification, had thicker residual stratum, and was higher in terrain. In rainy season, the meteoric water flew and corrode along the cracks, forming a complex network of fractures and caves. Combined with inherited uplift and the effective match of the NNE deep faults, oil and gas continuously charged into the reservoir space in the upland, forming the hoodoo fracture-cave reservoir with vertically quasi continuous distribution, high hydrocarbon abundance and high production.

Key words： Tahe Oilfield; Ordovician; karst slope; hoodoo upland; flower structure; fracture-cave reservoir; deep layer exploration; Tarim Basin
