【摘要】：锦204井区位于辽河盆地西部凹陷西斜坡南段第一断阶带上欢17块中部,位于欢喜岭油田的西南部,构造上位于辽河断陷西斜陂南部。断块北界和南界分别为欢17和锦16断层,欢17断层北为锦7块,锦16断层南为锦16块。锦204块构造形态为被断层复杂化的背斜构造,构造面积约3km2。块内主要发育的三套含油层系:自下而上分别为下第三系沙河街组大凌河油层、兴隆台油层、于楼油层,大凌河油层、兴隆台油层均已深度开发,是该块的主要开发层系,于楼油层未开发。包括锦204块、锦2-9-05块、锦2-8-04块和锦8-21-39块四个次级断块。主要开发目的层为兴隆台油层,部分油井发育于楼油层。锦204井区兴隆台油层上报含油面积1.3Km2,地质储量413×104t(锦2-8-04,锦204块),锦204块是欢17断块的次级断块,自1978年发现兴隆台油层至今,中部构造高部位已进入高含水生产阶段,而边部构造低部位井控程度低,油层分布规律认识程度不够,生产一直未打开局面,储量动用程度差,且从完钻井油气显示来看,上部于楼油层局部区域发育,资源量不落实。通过开展该块于楼、兴隆台油层精细地质研究及潜力评价来加深两套油层构造、储层、油层发育情况的认识,为锦204块于楼油层及断块边部井控程度低部位的兴隆台油层的有效开发奠定地质基础。主要研究内容如下:1、利用现有测井资料结合三维地震技术,落实于楼、兴隆台油层构造、沉积特征、储层发育情况。2、开展于楼、兴隆台油层“四性”关系研究。3、落实于楼油层储量。4、对区块进行综合评价,提出下步工作方向。预计通过本次研究,未来可在204井区部署直井9口,水平井2口。预期累产油5.9×104t,创经济效益12980×104元。通过该项研究,锦204块通过部署新井可实现稠油区块吞吐后期高产稳产,预计提高区块采出程度6%。该研究形成了一套适合稠油油藏地质特点的剩余油研究技术,为提高油田的整体开发效果做出了积极的贡献,对同类油藏的也具有较好的借鉴意义,具有广泛的科学指导意义和推广应用前景。
[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.
