Abstract

Bohai A Oilfield is the first fluvial facies oilfield in the Bohai Sea to be developed using a horizontal well layering system. It has the characteristics of thin single sand reservoir thickness, large differences in reserve scale, rapid lateral changes in reservoirs, and staggered stacking of multiple river channel sand bodies in the vertical direction. In production, it is characterized by rapid decline in ground pressure, rapid increase in water content, and large decrease in oil production. In order to achieve efficient development of Bohai A Oilfield, based on the dissection of single sand body configuration and the study of internal injection-production connectivity within the reservoir, a systematic optimization and balanced adjustment of injection-production principles has been developed. By changing the pressure gradient field between injection wells and production wells, a six character fine injection-production balance adjustment strategy of "infill, increase, control, limit, guide, and drive" has been implemented, resulting in a 3.6% increase in overall oilfield recovery rate, We have achieved the goal of continuously stable production of 1 million cubic meters in Bohai A Oilfield for 12 consecutive years. The production practice of Bohai A Oilfield has proven that the injection production balance adjustment technology has effectively solved the main challenges faced in the development of Bohai A Oilfield, enriched the means and methods for efficient development of offshore complex river facies oilfields, and has positive reference significance for the development of other similar oilfields.
