Abstract

Through the analysis of the Putaohua oil layer of Xingnan area’s geological information, sums up the fault form in section and the main form in the plane. Analyze the influence of different fracture dense belt for oil and gas migration and enrichment of sand body ,and controlling action on hydrocarbon accumulation. It’s found that the Xingnan Putaohua oil layer have mainly developed 4 fracture dense belts which are divided into horst-graben type belt and stepwise fracture belt. Two kinds of dense belt with A - SGR values are more than 30%, showing that both have a certain sealing property, and the stepwise fracture dense belt sealing is stronger than that of the horst-graben type fracture, but it is weak in ability of channel. The horst-graben type fracture dense belt of sand-controlling ability is stronger than that of the stepwise fracture dense belt, and it’s favorite for the formation of oil and gas reservoirs.
