摘要
文章评价了变质岩潜山裂缝储层,并建立了不同构造应力区裂缝特征及产能的相互关系,对变质岩潜山裂缝气田的高效率勘探开发具有十分重要的意义。结果表明,研究区根据构造应力场可划分为前翼带、转折端、后翼带和走滑区;不同构造区的应力场强弱控制了裂缝发育特征及产能差异,Ⅰ类转折端主要受印支期作用为主,挤压应力最强,裂缝发育最强,测试产量高,Ⅱ类走滑区主要受燕山、喜山期作用为主,挤压应力较强,裂缝发育中等,测试产量中等,Ⅲ类后翼带、Ⅳ类前翼带裂缝主要受印支、燕山期作用为主,挤压应力最弱,裂缝发育最差,测试产量最低。
In this paper,the fracture reservoir of metamorphic rock buried hill is evaluated,and the relationship between fracture characteristics and productivity in different tectonic stress areas is established,which is of great significance for the high-efficiency exploration and development of metamorphic rock buried hill fractured gas field.The results show that the study area can be divided into the front wing zone,the turning end,the back wing zone and the strike slip zone according to the tectonic stress area.The strength of the stress field in different tectonic areas controls the fracture development characteristics and productivity differences.The type I turning end is mainly affected by the Indosinian period,the compressive stress is the strongest,the fracture is the most developed,and the test yield is high;the type II strike slip area is mainly affected by the Yanshanian and Himalayan periods,the compressive stress is strong,the fracture development is medium,and the test yield is medium;the fractures of type III back wing zone and type IV front wing zone are mainly affected by Indosinian and Yanshanian,the compressive stress is the weakest,the fracture development is the worst,and the test yield is the lowest.
