A deep understanding of the basic geologic characteristics fine-grained shale layers in Paleogene 1st sub-member Kong 2 Member (Ek21) Cangdong sag, Bohai Bay Basin, is achieved through observation 140 m continuous cores and systematic analysis over 1 000 core samples from two wells. Basic geological conditions for oil accumulation are proposed based on unconventional theory gas. The rock system mainly developed interbedded formation felsic shale, calcareous dolomitic carbonates; high quality...
Compared with marine facies shale strata, lacustrine strata are more complicated in geological conditions, and thus difficult to explore develop. To realize economic exploration development of oil, the regularities accumulation high yield retained movable petroleum should be understood first. In this work, taking Kong 2 Member Sha 3 Paleogene Huanghua depression Bohai Bay Basin as examples, based on previous joint analysis results over ten thousand core samples latest oil testing, production...
As the main factors affecting stable and high production regularity of lacustrine shale oil are unclear, theoretical understandings, key exploration development technologies, effect have been analyzed summarized based on 700 m cores taken systematically from Paleogene Kong 2 Member 4 wells in Cangdong sag, over 100 000 analysis data formation testing data. Three understandings enrichment reached: (1) High-quality with "three highs one low" is material base for enrichment. (2) Medium—slightly...
The seismic sedimentology characteristics of sub-clinoformal shallow-water meandering river delta can be comprehensively analyzed by core, well logging and 3-D data. This paper summarizes the sedimentary pattern Suning area in Raoyang sag, Jizhong depression Bohai Bay Basin. In area, there are eight fourth-order sequences recognized from upper part Sha 1 Member (Es1s) to Dong 3 (Ed3), reflecting periodical change lake level. From central shore, transgressive highstand systems tracts, color...
Based on analysis of the basic geologic characteristics and enrichment controlling factors high coal rank coalbed methane (CBM) in south Qinshui Basin China, its mode, exploration development technologies are studied. Practices CBM proved that reservoirs this study area have following three major properties: (1) High rank, strong adsorption ability, good resources condition; (2) Low porosity, bimodal porosity structure, obvious "bottleneck" flow (3) low reservoir pressure gradient can...
Based on detailed core description and systematic joint test data, enrichment laws of continental shale oil have been examined deeply. Key technologies such as the identification quantitative evaluation method for sweet spot, precise design tracking horizontal well trajectory, low-cost volume fracturing technology whole process "slick water + quartz sand" formed. The research results show that pure Paleogene Kong 2 Member in Cangdong Sag is controlled by predominant fabric facies cross-over...
Based on core, thin section, X-ray diffraction, rock pyrolysis, CT scanning, nuclear magnetic resonance and oil testing data, the macro micro components, sedimentary structure characteristics, of Paleogene Kong 2 Member in Cangdong sag Huanghua depression evaluation standard method shale reservoir were studied to sort out best sections for horizontal wells. According dominant type, rhythmic logging curve four types lithofacies identified, namely, thin-layered dolomitic shale, lamellar mixed...
According to the theory of sequence stratigraphy based on continental transgressive-regressive (T-R) cycles, a 500 m continuous core taken from second member Kongdian Formation (Kong 2 Member) Paleogene in Well G108-8 Cangdong Sag, Bohai Bay Basin, was tested and analyzed clarify high-frequency cycles deep-water fine-grained sedimentary rocks lacustrine basins. A logging vectorgraph red pattern plotted, then stratigraphic framework with five-order formed for Kong Member. The were...
Based on systematic coring of 500 m Kong 2 Member the Paleogene Kongdian Formation in Cangdong sag Bohai Bay Basin, identification and XRD (X-Ray Diffraction) analysis over 1000 thin sections, a simplified method to quantitatively calculate contents fine grained minerals with conventional logging data such as acoustic travel time (AC) density log (DEN) has been proposed, quick lithologic "green mode" worked out this study. By fitting relationship between normalization curves mineral content...
