Deformation Mechanism and Vertical Sealing Capacity of Fault in the Mudstone Caprock

Journal of Earth Science 2019年第2期30卷 367-375页

作者： Xiaofei Fu Lingyu Yan Lingdong Meng Xiaobo Liu Laboratory of CNPC Fault-Controlling Reservoir Northeast Petroleum University Science and Technology Innovation Team in Heilongjiang Province"Fault Deformation Sealing and Fluid Migration"Northeast Petroleum University State Key Laboratory Base of Unconventional Oil and Gas Accumulation and Exploitation Northeast Petroleum University School of Energy Resource China University of Geosciences Daqing Yushulin Oilfield Development Co.Ltd.

The petrophysical property of mudstone often transforms from ductile to brittle in the process of burial-uplift. The deformation mechanism of fault in brittle and ductile mudstone caprock is different, which leads to the formation of different types of fault zone structure. Different methods are required to evaluate the sealing mechanism of those fault zones. Based on the caprock deformation mechanism, fault sealing mechanism, quantitative evaluation method of vertical fault sealing capacity is put forward in this study. Clay smear is formed in the process of plastic deformation and its continuity controls the sealing capacity of fault. The outcrop and oil field data have confirmed that when sealing parameter SSF is less than 4–7, the clay smear becomes discontinuous and then oil and gas go through the caprock and migrate vertically. Quantities of fractures are formed in mudstone in the process of brittle deformation. The fracture density increases with the increase of the fault displacement. When the fractures are connected, oil and gas go through the caprock and migrate vertically. The connectivity of fault depends on the displacement and the thickness of caprock. On the basis of the above, a method is put forward to quantify the connectivity of fault with the juxtaposition thickness of caprock after faulting. The research on the juxtaposition thickness of caprock after faulting of the member II of Dongying Formation in Nanpu depression and the distribution of oil and gas indicates when the juxtaposition thickness of caprock is less than 96.2 m, the fault becomes leaking vertically. In the lifting stage, with the releasing and unloading of the stress, the caprock becomes brittle generally and then forms through going fault which will lead to a large quantity of oil and gas migrate vertically.
