【摘要】：吉林油田公司伊通盆地油氣勘探近年來取得了許多突破性進展,在盆地構(gòu)造特征、地層層序、沉積相儲層特征、油氣成藏條件和分布規(guī)律等方面取得了許多新的成果認(rèn)識,通過新方法、新技術(shù)的運用,對斷陷盆地地質(zhì)認(rèn)識程度也逐漸提高,落實了一批油氣儲量,尤其是在岔路河斷陷中深層雙陽組通過儲層改造發(fā)現(xiàn)了工業(yè)性氣層,開創(chuàng)了中深層低滲透儲層天然氣勘探的新局面。由于前期的勘探評價工作多致力于中淺層油氣勘探,未系統(tǒng)進行低滲儲層氣藏形成機理和控制因素的研究工作,成藏機理尚不清楚,致使天然氣分布規(guī)律不清,制約著天然氣的勘探工作的順利進行。有必要對有效儲層的分布和形成機理開展針對性地研究工作,對中深層低滲砂巖氣成藏的有利區(qū)帶做出預(yù)測。以地層層序劃分與對比、建立等時地層格架,做到單井巖心相、測井相和地震相三相統(tǒng)一,明確沉積體系、沉積相及砂體縱橫向變化特征。在對致密儲層巖石學(xué)特征、儲層物性特征、孔隙結(jié)構(gòu)特征、成巖演化史及次生孔隙成因研究的基礎(chǔ)上,分析致密砂巖儲層的成因,特別是相對高滲儲層的成因,探討有利儲層的控制因素,建立預(yù)測方法。確定低滲氣藏形成機制,建立低滲儲層天然氣運聚模型。確定富氣規(guī)律和控制因素,進行有利區(qū)帶優(yōu)選、勘探潛力和資源潛力的評價。
[Abstract]:Yitong Basin oil and gas exploration in Jilin Oilfield Company has achieved many breakthroughs in recent years, the tectonic characteristics, stratigraphic sequence, sedimentary facies, reservoir characteristics, accumulation conditions and distribution of oil and gas has made many new achievements, through the new method, the application of new technology, also gradually improve the rift basin geology understanding degree, the implementation of a number of oil and gas reserves, especially in Chaluhe depression in deep Shuangyang group found industrial gas reservoir through the reservoir transformation, creating a new situation of natural gas exploration in the deep layer of low permeability reservoir. The exploration evaluation of previous work focused on the shallow oil and gas exploration no, the system working mechanism of reservoir formation and controlling factors of the reservoir of low permeability gas reservoir, the mechanism is not clear, resulting in the natural gas distribution is not clear, which restricts the natural gas exploration work smoothly. It is necessary to effective reservoir The distribution and formation mechanism to carry out targeted research work, with predicted favorable areas of deep low permeability to Sawa Kesunghide. Stratigraphic sequence division and correlation, the establishment of the isochronous stratigraphic framework, to achieve a single well core, well logging and seismic phase unified, clear sedimentary system, sedimentary facies and sand body vertical the variation characteristics on characteristics of tight reservoir petrology, reservoir characteristics, pore structure characteristics, based on diagenetic history and secondary pore Genesis evolution, analysis of the causes of the tight sandstone reservoir, especially the relatively high permeability reservoir causes, discussion on the control factors of reservoir, establish the prediction method. To determine the mechanism of the formation of low permeability gas reservoir, a reservoir of natural gas migration and accumulation model of low permeability gas rich. Determine the pattern and controlling factors of favorable zone optimization, exploration potential evaluation and potential resources.
