Development Optimization Technology and Application of Conglomerate Reservoir Based on Fine Geological Modeling

Abstract

Based on the comprehensive geological reservoir research on conglomerate reservoirs, the research contents and methods of a heterogeneous geological model for conglomerate reservoirs were systematically summarized. The model has been built making full use of seismic data, geologic data, drilling data, logging data, test data, etc. based on sedimentary facies modeling and property modeling. The model finely characterizes the transverse and longitudinal distribution characteristics of oil and gas in the field. The application of the above technology has provided effective guidance to new well optimization. 3 existing platforms have been optimized and utilized for the conglomerate gas reservoir, and 3 cluster inclined wells for conglomerate strata have been optimized, with the average single-well daily gas production of 6*104m3 and the daily condensate oil production of 56 barrels per day. A breakthrough has been made in reservoir fracturing in the conglomerate reservoirs. Reservoir fracturing has been implemented in 2 wells for the conglomerate oil reservoir, the daily oil production has been increased by 263 barrels per day, and the daily gas production has bee increased by 3.9*104m3.
