Embodiment Construction

[0021] In order to make the above and other objects, features and advantages of the present invention more comprehensible, the following specifically cites the embodiments, together with the accompanying drawings, for a detailed description as follows.

[0022] Based on the calculation formula of the operating cost per ton of oil, the method of the present invention will reduce the research direction of the cost per ton of oil from the perspective of geological reservoirs, from increasing the subhead: obtaining more oil volume, to reducing the molecule: reducing the cost required for each process of oil field development. Direct costs, namely improving the efficiency of the oilfield development system.

[0023]

[0024] The direct costs required for water flooding oilfields mainly come from the basic processes in oilfield development: such as figure 2 As shown, water well injection, oil well production, and surface oil and water treatment consume power costs. Here, the met...

Abstract

The invention provides a method for improving the efficiency of an oil field development system. The method for improving the efficiency of the oil field development system comprises the steps that 1,research of oil reservoir characteristics is conducted; 2, a water injection system is evaluated; 3, the adaptability of a bed set well pattern is analyzed; and 4, scheme implementation benefits areevaluated. The method for improving the efficiency of the oil field development system has great practicability and effects, energy consumption can be reduced by a large margin, accordingly, the development cost of a water-flooding old oil filed with the extra-long water-bearing period can be reduced by a large margin, the economic recoverable reserve is improved, the oil well blowing amount in the economic life period is increased, and the oil field development cost is reduced.

Description

technical field [0001] The invention relates to the technical field of water drive development oilfields, in particular to a method for improving the efficiency of an oilfield development system and reducing energy consumption for oilfield development. Background technique [0002] In the process of oilfield development, all water flooding reservoirs will inevitably face the trend of rising water cut, rising water-oil ratio, and increasing cost per unit oil production. This is an inevitable law of oilfield development. Reservoir staff use various methods to delay this situation, mainly by reducing water cut and increasing liquid volume, thereby increasing oil volume, reducing the cost per ton of oil by diluting the existing cost through the increase in oil volume, and improving Oilfield recovery and increase economic benefits. However, in the late stage of ultra-high water cut, it is more and more difficult and risky to increase the liquid volume or reduce the water cut. T...
