Research On Remaining Oil Distribution In Sheng Block 132

Nowadays, most of the oilfields in East of China have come to the middle and later development stage, the water cut of which have reach over 90%, meanwhile, most blocks have changed from major reservoirs to minor reservoirs. Facing with the demand and supply antinomy in domestic oilfield, the problem how to develop such reservoir efficiently becomes very important to us.Aiming at the problem above, the paper takes Sheng block 132 of Shengping oilfield as research area, use ECLIPSE numerical simulation software to research the distribution of the remaining oil in this block, and adjust the infill well project.According to the geological characteristics of the low permeability, severe water intrusion, and low production ability of the reservoir, using some geological, well test, DST and dynamic production resources, this paper researches the reservoir description and remaining oil detection. This paper synthesizes well test and numerical simulation methods to research the distribution of the remaining oil, in the numerical simulation, Aiming at the reservoir characteristic in this block, ECLIPSE is used to build 3D geological model in accord with the geological fact of the reservoir, some development indexes such as field geological reserve, field oil production, field water production, and field water cut are history matched according to the production history, the matching degree basically comes to the technique require, after analyzing all the development indexes we know that, the remaining oil mainly distributes in the lower construction part, low well network control area, near the fault and in the unswept or less swept area because of the antistrophic of the reservoir. Some rational adjusting projects are made, and after using ECLIPSE numerical simulation software to predict all the projects, and compare with each of them, the best one is chosen out, which accumulates valuable experience and technique on how to develop efficiently and how to enhance oil recovery in the later development stage for the low permeable reservoir around Daqing oilfield.
