Based on observation of cores and casting thin sections, reservoir fluorescence, hydrocarbon geochemical characteristics oil production test data, the factors controlling tight accumulation high in Da'anzhai Member Jurassic Ziliujing Formation central Sichuan Basin are studied. The shelly limestone, muddy shell limestone all oil-bearing Member. dissolved pores fractures matrix (microfractures, intercrystal pores) large area, which is reason why wells can keep low for a long period time. On...
Recently, significant oil discoveries have been made in the shallower pay zones of Jurassic Badaowan Formation (J1b) Mahu Sag, Junggar Basin, Northwest China. However, little work has done on geochemical characteristics and origins J1b reservoir. This study analyzes 44 14 source rock samples from area order to reveal their organic oils. The oils are characterized by a low Pr/Ph ratio high β-carotene gammacerane indices, which indicate that they were mainly generated rocks deposited...
The Fengcheng Formation (P 1 f) source rock, which was deposited in an alkaline water body, is one of the most significant rocks Mahu sag, Junggar Basin. However, its evolution and mechanism organic matter accumulation are still not understood. Using seismic, core, log data, P f divided into 3 third-order sequences, i.e., SQ1, SQ2, SQ3, from bottom to top. Pyrolysis data core samples shows that SQ1 SQ3 mainly characterized by poor fair rocks, with Type III II 2 kerogen, while SQ2 good...
Bitumen's influence on reservoir properties and hydrocarbon accumulation in Santai area was studied by experiment measures geochemical evidences. The porosity permeability of the sandstones containing bitumen increased significantly dissolving experiments, implying that strongly influences properties. analysis reveals there were two stages accumulation. In first stage oil migrated into coarse-grained sandstone then degraded to bitumen, which deteriorated second had migrate fine-grained...
Reservoir bitumen is not readily identified on typical log suit, where usually read as oil reservoir. We comparatively analyze the experimental data of nuclear magnetic resonance (NMR) before and after dissolving bitumen-rich samples. The short transverse relaxation times (T2) are characteristics zones, NMR porosity relative abundance in A volumetric rock model was used to reconcile core well calculate saturation reservoir bitumen. can be applied more reliably evaluation production planning.
Solid bitumen was identified in the pore spaces of Jurassic and Triassic sandstone reservoir Santai Area, Junggar Basin, NW China, which limits economic petroleum production, even influencing hydrocarbon accumulation. Organic geochemical techniques were figured out origin its formation mechanisms. Carbon isotope characteristics crude oil bitumen-reservoir extracts suggests mainly derived from sapropelic-type source rock Pingdiquan Formation, deposited semideep deep lacustrine environment....
Deposit bitumen is a highly viscous, asphaltene-rich hydrocarbon that can fill in the pores as cement reduce porosity deposit. The authors comparatively analyzed experimental data of nuclear magnetic resonance before and after dissolving bitumen-rich core samples. short transverse relaxation times (T2) consequently lower NMR are characteristics zones. An method was used to reconcile well calculate saturation
A major exploration breakthrough has been made in the Mahu Sag, Junggar Basin. However, origin of oils from Triassic Baikouquan Formation (T1b) remains debated. In this study, 20 and 44 cores were selected to investigate their distributions tricyclic terpanes (TTs). The results show that relative abundance TTs is higher than those hopanes due a high maturity. Permian Wuerhe (P2w) are dominated by C20TT. Fengcheng (P1f) samples, predominated C23TT, mature high-mature, while Jiamuhe (P1j)...
Trinity reservoir refers to the normal oil, heavy and bitumen distributed from bottom top in Wuerhe oilfield affected by geological movements. Discriminating between producible oil other hydrocarbons is critical for production planning. In this study, NMR experimental data, chemical compositions, structure of samples are compared analyzed. Geological movements cause an increase density, a decrease saturated hydrocarbons, depletion N-alkane, which finally results shorter transverse relaxation...
From 5000 m underground to the surface, there is a multi-layer hydrocarbon reservoir under Wuerhe nose uplift in Junggar Basin. Light oil, heavy oil sand, and solid bitumen are found Permian Cretaceous strata. The normal crude present can easily ignored by explorers. To effectively exploit petroleum mineral resources Basin, geochemical characteristics of oils different layers were analyzed. It concluded that minerals came from source rocks alkaline lacustrine facies. Combined with tectonic...
In order to clarify the provenance of 1st member Zhongjiangou formation in Wudun sag, Dunhuang basin, structural attributes, weathering and sedimentary characteristics area were analyzed by means element geochemistry, so as determine differences sediment sources different well areas. The results show that higher Al2O3 K2O contents, enrichment large ion lithophile elements high field strength elements, while iron magnesium are relatively deficient, there medium degree differentiation light...
Heavy oil is one of the most important unconventional petroleum resources and its formation mechanisms biodegradation. The molecular composition characterization crucial for assessment different degrees In this work, detail investigations acids polar NSO compounds in levels biodegraded oils from Bongor Basin were carried out by negative ion electrospray ionization (-ESI) Fourier transform cyclotron resonance mass spectrometry (FT-ICR MS). results show that heteroatomic crude mainly are...
Rock extracts and oil samples has been detected high abundance of 18α(H)-neohopane fromYanchang Formation in Ordos Basin. The results showed that the black mudstone was deposited anoxic condition semi-deep or deep lacustrine facie low Chang 7 member. dark mudstones with 9 member they were suboxic shallow facies. origin concentration have relationship sedimentary environment organic matter type. geochemical significance can effectively solve oil-source correlation research area.
