【摘要】：錦204井區(qū)位于遼河盆地西部凹陷西斜坡南段第一斷階帶上歡17塊中部,位于歡喜嶺油田的西南部,構(gòu)造上位于遼河斷陷西斜陂南部。斷塊北界和南界分別為歡17和錦16斷層,歡17斷層北為錦7塊,錦16斷層南為錦16塊。錦204塊構(gòu)造形態(tài)為被斷層復(fù)雜化的背斜構(gòu)造,構(gòu)造面積約3km2。塊內(nèi)主要發(fā)育的三套含油層系:自下而上分別為下第三系沙河街組大凌河油層、興隆臺油層、于樓油層,大凌河油層、興隆臺油層均已深度開發(fā),是該塊的主要開發(fā)層系,于樓油層未開發(fā)。包括錦204塊、錦2-9-05塊、錦2-8-04塊和錦8-21-39塊四個(gè)次級斷塊。主要開發(fā)目的層為興隆臺油層,部分油井發(fā)育于樓油層。錦204井區(qū)興隆臺油層上報(bào)含油面積1.3Km2,地質(zhì)儲量413×104t(錦2-8-04,錦204塊),錦204塊是歡17斷塊的次級斷塊,自1978年發(fā)現(xiàn)興隆臺油層至今,中部構(gòu)造高部位已進(jìn)入高含水生產(chǎn)階段,而邊部構(gòu)造低部位井控程度低,油層分布規(guī)律認(rèn)識程度不夠,生產(chǎn)一直未打開局面,儲量動用程度差,且從完鉆井油氣顯示來看,上部于樓油層局部區(qū)域發(fā)育,資源量不落實(shí)。通過開展該塊于樓、興隆臺油層精細(xì)地質(zhì)研究及潛力評價(jià)來加深兩套油層構(gòu)造、儲層、油層發(fā)育情況的認(rèn)識,為錦204塊于樓油層及斷塊邊部井控程度低部位的興隆臺油層的有效開發(fā)奠定地質(zhì)基礎(chǔ)。主要研究內(nèi)容如下:1、利用現(xiàn)有測井資料結(jié)合三維地震技術(shù),落實(shí)于樓、興隆臺油層構(gòu)造、沉積特征、儲層發(fā)育情況。2、開展于樓、興隆臺油層“四性”關(guān)系研究。3、落實(shí)于樓油層儲量。4、對區(qū)塊進(jìn)行綜合評價(jià),提出下步工作方向。預(yù)計(jì)通過本次研究,未來可在204井區(qū)部署直井9口,水平井2口。預(yù)期累產(chǎn)油5.9×104t,創(chuàng)經(jīng)濟(jì)效益12980×104元。通過該項(xiàng)研究,錦204塊通過部署新井可實(shí)現(xiàn)稠油區(qū)塊吞吐后期高產(chǎn)穩(wěn)產(chǎn),預(yù)計(jì)提高區(qū)塊采出程度6%。該研究形成了一套適合稠油油藏地質(zhì)特點(diǎn)的剩余油研究技術(shù),為提高油田的整體開發(fā)效果做出了積極的貢獻(xiàn),對同類油藏的也具有較好的借鑒意義,具有廣泛的科學(xué)指導(dǎo)意義和推廣應(yīng)用前景。
[Abstract]:The Jin204 well area is located in the middle of Huan 17 block of the first fault terrace in the southern section of the west slope of the western depression of Liaohe basin, located in the southwest of Huanxiling oilfield and structurally in the southern part of Xijiaopi in the Liaohe fault depression. The north boundary and south boundary of fault block are Huan 17 and Jin 16 fault respectively, Huan 17 fault north is Jin 7 block, Jin 16 fault south is Jin 16 block. Block Jin204 is an anticline structure complicated by faults with an area of about 3km2. Three sets of oil-bearing strata are mainly developed in the block: from bottom to top, they are respectively Daling River reservoir, Xinglongtai reservoir, Youlou reservoir, Dalinghe reservoir and Xinglongtai reservoir of the Lower Tertiary Shahejie formation, which are the main development strata of this block. Yulou reservoir has not been developed. It includes four sub-blocks: Jin204 block, Jin 2-9-05 block, Jin 2-8-04 block and Jin 8-21-39 block. The main development target layer is Xinglongtai reservoir, and some oil wells are developed in Lou reservoir. Xinglongtai oil reservoir in Jin204 well area is reported to have an oil bearing area of 1.3 km ~ 2, geological reserves are 413 脳 10 ~ 4t (Jin 2-8-04, Jin 204, Jin 204) are secondary fault blocks of Huan 17 fault block. Since the discovery of Xinglongtai oil reservoir in 1978, the high structural position in the central part has entered the stage of high water-cut production. However, the well control degree of low position of edge structure is low, the understanding of reservoir distribution law is not enough, the situation of production has not been opened up all the time, the level of reserve production is poor, and from the oil and gas display after drilling, the upper part is developed in the local area of Lou reservoir, and the resource quantity is not carried out. By carrying out the fine geological research and potential evaluation of the reservoir in Yulou and Xinglongtai to deepen the understanding of the development of the two sets of reservoir structures, reservoirs and reservoirs, It lays a geological foundation for the effective development of Xinglongtai reservoir in Block Jin204, which is located at the low level of well control in the loo reservoir and the edge of the fault block. The main research contents are as follows: using the existing logging data combined with three-dimensional seismic technology, the main research work has been carried out in Lou, Xinglongtai reservoir structure, sedimentary characteristics, reservoir development status. The relationship between "four properties" of Xinglongtai reservoir is studied. 3, which is carried out in the reservoir reserves. 4. The comprehensive evaluation of the block is carried out, and the next working direction is put forward. Through this study, 9 vertical wells and 2 horizontal wells can be deployed in 204 well area in the future. The cumulative oil production is expected to be 5.9 脳 10 ~ 4 t and the economic benefit is 12980 脳 10 ~ 4 yuan. Through this study, Jin204 block can achieve high and stable production in the later stage of huff and puff in heavy oil block by deploying new well, and the recovery degree of block is expected to be improved by 6%. This study has formed a set of remaining oil research techniques suitable for the geological characteristics of heavy oil reservoirs, which has made a positive contribution to improving the overall development effect of oil fields, and has a good reference significance for the similar reservoirs. It has extensive scientific guiding significance and application prospect.
