含夹层碳酸盐岩储层裂缝发育规律研究
|
摘要
裂缝作为碳酸盐岩储层中重要的储集体和流体渗流通道,其预测为勘探和开发领域的难题。以塔里木盆地中央隆起南缘玛扎塔格构造带奥陶系为研究对象,钻井和录井等资料为基础,利用离散元数值模拟方法对工区局部和整体进行应力场模拟并分别建立模型。在此基础上,通过不同区域沉积剖面上的灰泥岩分布,进行了应力场与破裂关系研究。发现在整体厚为8 m、泥质夹层厚为0.8 m(灰泥比为10∶1至14∶1)和倾角约为38°时,最有利于裂缝发育。
Fractures, as conducts and porous, play important roles for the exploration and development of carbonate reservoirs. However, their distribution prediction is a difficult problem in the field for the carbonate reservoir. In view of the multi-period and complexity of Ordovician fracture development in Hetian River gas field, this paper studies the relationship between stress field and rupture based on drilling and logging data. Results show that the favorable conditions for the fracture development are mud barrier thickness of 0.8 m and dip angle of 38°. The conclusion is of great significance to guide the actual production of oil and gas field.
