Wettability of acid volcanic reservoir rock from the Hailar Oilfield, China, was studied with crude oils of different acid numbers generated from an original crude oil with an acid number of 3.05 mg KOH/g. The modifed oils and their resultant acid numbers were： A （2.09 mg KOH/g）, B （0.75 mg KOH/g）, C （0.47 mg KOH/g）, D （0.30 mg KOH/g）, and E （0.18 mg KOH/g）. Contact angles and improved Amott water indexes were measured to study the effects of temperature and acid number on the wettability of the acid volcanic reservoir rock. Experimental results indicated that the wettability was not sensitive to variation in temperature when using the same oil, but the acid number of the crude oil was a key factor in changing the wettability of the rock. The Amott water index, Iw was an exponential function of the acid number, and the Amott water index increased as the acid number decreased （i.e. Amott water index exponentially decreased with the acid number increase）. The Iw value of the core saturated with oil A, with an acid number of 2.09 mg KOH/g, ranged from 0.06 to 0.11, which indicated low water wetness. If the acid number of the oil decreased to 0.18 mg KOH/g, the Iw value increased to 0.95, which indicated strong water wetness. The contact angle decreased from 80~ to 35~ when the aid number decreased from 0.75 to 0.18 mg KOH/g, indicating a change towards more water wet conditions. The oil recovery by spontaneous imbibition of water also increased as the acid number of the oil decreased. As an example, at 80 ~C, the recovery of Oil A with an acid number of 2.09 mg KOH/g was only 7.6%, while Oil E with an acid number of 0.18 mg KOH/g produced 56.4%, i.e. an increase of 48.8%.

The complex plate collision process led the South Yellow Sea Basin (SYSB) to go through an intensity tectonic inversion during the early Cenozoic， leading to a regional unconformity surface development. As a petroliferous basin， SYSB saw intense denudation and deposition processes， making it hard to characterize their source-to-sink system(S2S)， and this study provided a new way to reveal them quantitatively. According to the seismic interpretation， it was found that two types of tectonic inversion led to the strata shortening process， which was classified according to their difference in planar movements: dip-slip faults and strike-slip ones. As for dip-slip faults， the inversion structure was primarily formed by the dip-slip movement， and many fault-related folds developed， which developed in the North Depression Zone of the SYSB. The strike-slip ones， accompanied by some negative flower structures， dominate the South Depression Zone of the SYSB. To reveal its source-to-sink(S2S) system in the tectonic inversion basin， we rebuild the provenance area with detrital zircon U-Pb data and heavy mineral assemblage. The results show， during the Eocene(tectonic inversion stage)， the proximal slump or fan delta from the Central Uplift Zone was prominently developed in the North Depression Zone， and the South Depression Zone is filled by sediments from the proximal area (Central Uplift Zone in SYSB and Wunansha Uplift) and the prograding delta long-axis parallel to the boundary faults. Then， calculations were conducted on the coarse sediment content， fault displacements， catchment relief， sediment migration distance， and discussions about the impact factors of the S2S system developed in various strata shortening patterns with a statistical method. It was found that， within the dip-slip faults-dominated zone， the volume of the sediment routing system and the ratio of coarse-grained sediments merely have a relationship with the amount of sediment supply and average faults br
