摘要
MDT取样是在中途测试阶段进行的一种新型井下PVT油气取样方法。通过对准噶尔盆地腹部、南缘8个油气藏的MDT取样获得的储层流体高压物性资料的统计对比,分析总结了MDT取样在识别油气藏类型、判断油气界面、获取可靠的储层油气流体性质方面的作用及意义。同时指出,MDT样品存在钻井泥浆污染问题。
MDT sampling is a new type of down hole PVT oil and gas sampling method during DST. Based on the comparison of statistics of PVT data of reservoir fluids obtained from MDT sampling in the hinterland and southern margin of Junggar Basin, this paper analyzes and summarizes the function and significance of MDT sampling in identifying reservoir types, acquiring reliable reservoir fluids properties and deciding the WOC. It has also been pointed out that contamination problem is present in drilling mud for MDT samples.
