Abstract

With the help of volume fracturing technology of long horizontal wells, tight reservoirs in Block X have initially been effectively developed in a large scale. In the initial stage, the daily oil production of a single well was 15.5t, achieving the production capacity construction goal. However, during the mining process, problems such as rapid decline in formation pressure and production were encountered. In order to fully utilize formation energy and effectively control production decline, this article comprehensively considers the impact of factors such as high pressure physical properties of crude oil, reservoir sensitivity, and reservoir damage on the production capacity of a single well. Through fracture control numerical simulation technology, a study was conducted to determine the reasonable bottom hole flow pressure at different development stages, A reasonable bottom hole flow pressure chart was drawn for the tight reservoir in Block X at different development stages. And through production logging data, the feasibility of a reasonable method for determining bottom hole flow pressure has been confirmed. Adjusting the production system according to the chart resulted in a decrease in the monthly decline rate of oil wells and achieved good development results.
