焉耆盆地发现宝浪、本布图油田后,种马场构造带以其两凹一隆的构造背景成为焉耆盆地油气勘探的重点, 1996~ 1997年部署钻探了马 1、马 2、马 3井,录井见到丰富的油气显示,但未获工业油气流。研究认为钻探失利是所钻圈闭构造位置较高、剥蚀强烈、油气保存条件差所致。种马场构造带储层岩石结构及成分成熟度低,成岩作用强烈,储层物性较差,但西部好于东部。目的层八道湾组、三工河组均处于晚成岩A期、次生孔隙较发育;种马场构造带处于燕山期南北两凹陷油气运移的有利指向区,亦可捕获四十里城次凹喜山期二次生成的油气,油源丰富;地层剥蚀程度和断层的活动性是油气保存的关键因素。综合分析认为种马场构造带低断阶、中生界保存较全的断鼻、断块圈闭及八道湾组内部的背斜、岩性圈闭具有油气勘探价值。
After the discovery of Baolang and Benbu Tuo oil fields in Yanqi Basin, the tectonic belt of the stud farm has become the focus of oil and gas exploration in the Yanqi Basin since its tectonic setting of the two concave and one profusion. From 1996 to 1997, Ma 1, Ma 2 and Ma 3 wells were drilled and drilled. Logging wells to see a wealth of oil and gas show, but not industrial oil and gas flow. The study suggests that the loss of drilling is due to the higher position of the trapped traps, strong denudation and poor oil and gas storage conditions. Stallion tectonic belt reservoir rock structure and composition of low maturity, strong diagenesis, poor reservoir properties, but the west is better than the east. The Badaowan Formation and the Sangonghe Formation of the target formation are both late A diagenetic stage and secondary porosity is well developed. The stratum structural belt is located in the favorable point of hydrocarbon migration in the northern and southern Sag of the Yanshanian period, Himalayan secondary oil and gas generation, oil rich; formation denudation and fault activity is the key factor in the preservation of oil and gas. The comprehensive analysis shows that the breccia field tectonic zone has a lower fault level, the Mesozoic well-preserved fault nose, fault block traps and the anticlines and lithological traps within the Badaowan Formation have the potential of oil and gas exploration.
