By study ing on the grav ity structure, the geolog ists like
T ian Sh id ian and W ang B ing sum up the seven types of
g rav ity la teral m ovem en ts such as slide fau lt terrace, ro lling
anticline, inc lined fault block, sloughing antic line, s lip and
over lap structure, com pac ted structure and d iap iric structure.
Based on the interpretation for the se ism ic pro file o fWA85-
105, Suqiao bur ied h ill shou ld be long to the co llapse
structure patte rn w ith form a tion disso lution, m ak ing the
g rav ity structures inc rease to e ight types. Suqiao buried h ill
fau lt block hydrocarbon reservo ir is Ordov iuc ian auth ig enetic
and self - preserv ing o il reservo ir, which is stacked by
over ly ing C arbon iferous and Perm ian natura l g as layer and
form s a typical com plica ted hydrocarbon reservo ir. The
establishment for fault block com plicated hydrocarbon
reservo ir of Suqiao buried h ill can prov ide an ex am ple fo r o il
and gas finding in Palaeo zo ic, M esopro tozo ic and
Pa laeopro tozo ic reservo irs in no rth Ch ina.
