Abstract

Lamaidean oilfield is a sandstone oil reservoir with low porosity, low permeability and low abundance, with extremely broken structure, many faults, deep burial, poor physical properties and complicated oil-water relationship, which makes the development extremely complicated. After the production is put into operation, the production decreases rapidly, and there is the development contradiction of not injecting and not extracting in the lower part of the side, how to improve the development effect of the oilfield and supplement the formation energy as soon as possible is an important issue for the stable production of the oilfield, which is of great significance for controlling the decrease of the production of the oilfield and improving the recovery rate of the crude oil. Based on the well development, reservoir prediction, tectonic/fault development, etc., the drilling sequence was formulated to flexibly vary the well locations while following the well placement principles. The research results show that the water-driven recovery rate in the pre-distribution area of the calculated wells is 22.37 %, with a combination of water injection at low parts of the tectonics and flexible water injection at points, the ratio between the number of oil and water wells is 3.25:1, the production hourly rate is 300 days, the daily oil production of a single well is 3.0 t on a stable basis, and the capacity of the wells can be built up to 0.81×10⁴ t.
