摘要
通过研究泥浆侵入对电阻率测井的影响,利用双侧向求取地层真电阻率Rt,并理论推导了一种直接利用深、中、浅电阻率组合测井资料计算泥浆侵入深度的方法,并根据泥浆污染深度与泥浆侵入深度的关系式,得到储层泥浆污染程度评价定量指标,实现了储层泥浆污染程度的定量评价,分析认为百色盆地田东油田部分那读组储层优质储层产量低主要原因是由于泥浆污染严重造成。
By studying the effect of mud invasion on resistivity logging,dual laterlogging is used to calculate true formation resistivity Rt.Through theoretical derivation,mud invasion depth is introduced from combination data of deep,medium and shallow resistivity logging.The quantitative evaluation indices of mud pollution level of the reservoir is achievd according to the relational expression of mud contamination depth and mud invasion depth.It is believed that the main cause of quality reservoir of low yielding in Tiandong oilfield is serious mud pollution.
