在油气井钻探过程中,泥浆及其滤液侵入储集层,不可避免地对测井资料解释产生影响,利用高分辨率阵列感应准确确定原状地层电阻率、冲洗带电阻率和侵入半径,克服了常规电阻率测井纵向分辨率低、探测深度浅等缺点。分析了东营凹陷中央隆起带泥浆滤液的侵入特性,研究了高分辨率阵列感应在确定泥浆滤液侵入及储层渗透性、识别油气层、预测产能等方面的应用。

A plugging agent XNJG was prepared with polysilicone gelling solution and crosslinking stabilizing solution as materials for resolving the problems of profile modification agent losing during plugging and modifying high permeable zone or tiny crack in middle and low permeable reservoir. XNJG settled easily in stratum and resisted temperature 80-160 ℃ and salinity 3 000-5 0000 mg/L. It showed the performances of good hot resistance,good outwash resistance and strong profile modification to anisotropic cores. The results of the application tests in Gudao Oilfield were satisfying.

对土—结构动力相互作用的效应和分析方法进行了简要的陈述,着重对解析解的分析方法进行了分析讨论。
