巖歧
英文
stratum-
The regularity of accumulation distribution is ascertained and directs the exploration orientation. the main results obtained in this paper are : 1. the analyses of hydrocarbon - bearing rock, reservoir, caprock and oil & gas reservoir indicate the source of oil & gas, the space for reservoir, requirement for preservation, reservoir type and its basic characters. 2. it is realized by the analyses of sealing up capability of caprock and faults, and fault ' slatter stability from microcosmic and macroscopic that the wide - spread regional caprock of nm t prevented oil & gas of neogene from diffusing fault movement in neogene less violated and fault displacement decreased, which are advantageous for the preservation of oil & gas reservoir. and latter structure movement usually formed the accunulation of oil & gas in neogene. 3. the research of history of hydrocarbon generation and expulsion of main hydrocarbon - bearing rock in qikou depression reveals the threshold depth and the fime of hydrocarbon generation and expulsion
項目研究取得了如下認識： 1 、對烴源巖、儲集層、蓋層及油氣藏展開分析，明確了歧口凹陷上第三系油氣藏的油氣來源、儲集場所、保存條件和油氣藏類型及其基本特徵； 2 、從微觀和宏觀上對蓋層的封蓋能力以及斷層封堵和後期穩定性進行分析，認識到明下段區域蓋層的廣泛分佈阻止了上第三系油氣藏的油氣逸散，同時上第三系斷層活動減弱，斷距較小，對油氣藏的保存較為有利。From the dongying formation ( ed ) to neogene, the shahejie formation was located in the late diagenetic stage a1 ~ a2 ; the oil and gas pools formed in a wide scale. at present the lower e2s3, with overmatured source rocks and low porosity reservoir rocks, gets into the late diagenetic stage b - c in the northern qibei sag where is not favorable for petroleum accumulation, but the others of the shahejie formation are locate still in the late diagenetic stage a1 - a2 and propitious to form oil and gas pools based on the diagenetic numerical modeling under the condition of overpressure, we build a multiple unit cubic equation model for porosity prediction, as the result of the application of qibei sag, the prediction error is less than 2 %, and the precision excess that of foreign same model
歧北凹陷的模擬結果表明，在沙河街組沉積末沙河街組三段就進入晚成巖階段a _ 1期，油氣藏開始形成；在東營組沉積時期晚第三紀，沙河街組大部分地層處于晚成巖階段a _ 1 a _ 2期，生、儲、蓋層發育，是其主要成藏期；現今在歧北凹陷北部沙三段下部進入晚成巖階段b c期，儲層物性較差、不利於成藏，其他層段仍處于晚成巖階段a _ 1 a _ 2期，有利於油氣藏的形成。In this paper, using sufficiently drilling data, log data -, core data and 3d seismic data, stratum sequence qikou depression, huanhua sag is partitioned by using sequence stratigraphy theory
本文利用三維地震資料、測井、巖芯、巖屑等資料，對黃驊坳陷歧口凹陷第三系進行層序地層學研究。4. based on the research of geochemical characters of hydrocarbon source rock and comparison of oil and gas sources, it is indicated that the condensed oil and gas in buried hills mainly came from es3 effective hydrocarbon source rock of type iii kerogen - type ii2 kerogen in banqiao deprssion and qikou depression beside both sides of the tilting horst, and which is the main source of buried hill with early reservoir and late oil and gas source
4根據烴源巖地球化學特徵和油氣源對比，指出潛山凝析油氣主要來自翹傾地壘塊兩側板橋和歧口凹陷的沙三段腐植-偏腐植型有效烴源巖，該凝析油氣是「新生古儲」型潛山的主要油氣源。The main process of hydrocarbon generation and expulsion in es3 hydrocarbon - bearing rock began in the late of ed epoch and ended in ng epoch ( equals to 30 - 12ma ). the generation and expulsion of oil of es1 epoch began in nm ? epoch and ended by the deposition of quaternary system ( equals to 10 - 5ma ) and reached its peak after the deposition of nm epoch
3 、歧口凹陷主要烴源巖生排烴史的研究確定了門限深度和生排烴時間，沙三段源巖的主要生排烴作用過程是在東營末期至館陶期完成的（相當於30 ? 12ma ） 。Nonce, the system of diagenetic numerical modeling for the stratum under the conditions of normal pressure has been set up. in lots of sags rich of petroleum in the basins of eastern china, such as qibei sag of bohaiwan basin, there are plenty of deep - buried overpressure reservoir
但在中國東部許多盆地的富油氣凹陷，如渤海灣盆地歧北凹陷，油氣藏分佈在深層超壓地層中，超壓條件下成巖作用的數值模擬尚不完善，更不用說孔隙度預測了。With regard to the causes of formation and sources of salt, people have different point of views in different basins, and different depositional models are set up, even in one same basin there are also divergent view to exist different opinions still exist on the position of the salt bearing strata in sequence stratigraphy. it will greatly influence the exploration level of resources in salt - bearing basin if the above doublts can not be made clear. in this way, it will be of great significance to make it clear about the above issues and the relationships about salt and oil & gas
對于鹽巖的成因及鹽源在不同盆地有不同的認識，並建立了各自的沉積模式，就是同一含鹽沉積盆地或含鹽沉積凹陷人們的認識依然分歧很大，關于鹽巖在層序地層中的位置人們的認識依然不同，對這些問題的認識不清將極大的影響對人們含鹽盆地的能源勘探開發水平，因此搞清鹽巖的成因及其與油氣聚集的關系具有重要意義。Furthermore, we are concerned that there was a significant number of slope failures involving new slopes which had not been subject to proper geotechnical control, and the practice of allowing the works departments the discretion of not making geotechnical submissions is at variance with the stated intention of the geotechnical engineering office ( geo ) that all the new slopes are subject to its geotechnical control
此外，委員會關注到，涉及未受適當巖土工程管制的新斜坡的崩塌事故為數眾多，而且準許工務部門自行決定不呈交巖土工程設計文件的做法，與土力工程處所述的意向，即規定所有新斜坡均須由該處實施巖土工程管制有分歧。分享友人
