本研究通过物理模拟来验证数值模拟,证实在钻井液动态侵入条件下,地层电阻率与地层参数、流体性质以及测井时间有关;储层物性越好受到泥浆固相颗粒的污染越严重,滤液侵入越浅;储层含水饱和度越高,滤液侵入速度越快。通过对钻井液侵入数值模拟和物理模拟的结合研究,开展钻井液侵入对储层电阻率测井响应变化规律的探索。
In this study, the numerical simulation is verified by physical simulation. It is confirmed that the formation resistivity is related to the formation parameters, fluid properties and logging time under the condition of dynamic intrusion of drilling fluid. The better the reservoir physical properties are, the more serious the contamination by the mud solid particles, The more intrusion; the higher the water saturation of the reservoir, the faster the filtrate invades. Through the combination of numerical simulation and physical simulation of drilling fluid intrusion, this paper probes into the variation law of reservoir resistivity logging response by drilling fluid invasion.
