Logging suite selection of the low resistivity hydrocarbon reservoir in the area of Liaohe foreshore

The mechanism of low hydrocarbon reservoir has relations with brine drilling liquid invasion, low structure amplitude and high irreducible water saturation after comprehensive analysis. These factors often cause logging interpretation and evaluation troubles for the hydrocarbon layers. Some oil and gas layers were interpreted by mistake and a few of them were neglected. To select logging suite reasonably can improve the logging data and be helpful to the logging interpretation. An appropriate logging suite including HDIL, MRIL and TBRT log was put up according to the geological features of Liaohe foreshore. Additional 54 oil and gas layers were discovered in the practice of Taiyangdao and Kuihuadao oilfield and 13 layers were con-firmed by oil tests. This method enhanced the well logging interpretation accuracy and has good feasibility.
