【摘要】：锦16块兴隆台油层分三套层系开发,其中三层系含油面积1.9km2,地质储量510.51×104t,标定采收率51.5%。目前总井18口,开井17口,日产液948t/d,日产油81t/d,含水91.78%,采出程度45.9%;水井总井5口,开井5口,日注水901m3/d,累注水857×104 m3/d。目前断块油水井主要集中在断块北部,而南部由于高含水油井大部分上返至一、二层系,导致井网对储量的控制程度降低;同时三层系局部发育微高点,且非主力层有一定的产油潜力,但水淹特点不甚清楚。因此该套层系具有二次开发的潜力。应油藏工程、精细地震解释,对区块进行精细油藏描述研究,落实构造、储层、沉积相,搞清剩余油分布规律,评价开发效果。通过本课题的开展,有望在断块南部和微构造高点的非主力油层部署新井,完善注采井网;同时开展二元驱可行性评价,为下步对三层系整体转变开发方式做准备。
[Abstract]:The Xinglongtai reservoir of Jin16 block is developed in three sets of strata, in which the oil-bearing area of the three-layer system is 1.9 km ~ 2, the geological reserves are 510.51 脳 10 ~ 4t, and the calibrated recovery rate is 51.5%. At present, there are 18 wells, 17 wells, 948t / d fluid, 81t / d oil production, 91.78% water cut and 45.9% recovery, 5 wells with 5 wells, 901m3 / d, 857 脳 104m3 / d respectively. At present, the fault block oil and water wells are mainly concentrated in the north of the fault block, while in the south, most of the oil wells with high water cut return to the first and second layers, resulting in a decrease in the control degree of the well pattern over the reserves. At the same time, the local development of the three-layer system is slightly high, and the non-main layer has a certain oil production potential, but the characteristics of water flooding are not very clear. Therefore, the suite system has the potential of secondary development. In response to reservoir engineering, fine seismic interpretation, fine reservoir description study on the block, implementation of structure, reservoir, sedimentary facies, clear distribution of remaining oil, evaluation of development results. Through the development of this project, it is expected that new wells will be deployed in the non-main reservoirs in the south of the fault block and the micro-structural high point to perfect the injection-production well pattern, and at the same time, the feasibility evaluation of binary flooding will be carried out in order to prepare for the further transformation of the development mode of the three-layer system.
