Productivity prediction system and method based on oil gas content

Abstract

The invention discloses a productivity prediction system and method based on oil gas content, and belongs to the field of oil development and engineering. The system comprises a static parameter confirming module, an oil reservoir and engineering parameter confirming module, a productivity prediction model establishment module and an evaluation module, wherein the static parameter confirming module is used for collecting logging information of strata through logging equipment, partitioning a plurality of reservoir beds according to the logging information, performing recognition and evaluation on any one of the plurality of reservoir beds through a lithology identification method, and confirming that static parameters of one reservoir bed is obtained; the oil reservoir and engineering parameter confirming module is used for performing reservoir engineering analysis on the region where the logging is located, and obtaining oil reservoir and engineering parameters of the region; the productivity prediction model establishment module is used for establishing a productivity prediction model based on the oil gas content and obtaining a stratum flow of an oil layer through calculation according to the static parameters in the reservoir beds and the oil reservoir and engineering parameters of the region; and the evaluation module is used for classifying the reservoir beds of the logging according to the stratum flow of the oil layer. The productivity prediction system and method based on the oil gas content can solve the problem that oil phase permeability is difficult to confirm, thereby improving the accuracy of the productivity prediction.

Description

technical field [0001] The invention belongs to the field of petroleum development and engineering, in particular to a production capacity prediction system and method based on oil and gas content. Background technique [0002] At present, the rapid development of the national economy and the increasing dependence on oil and natural gas resources require the oil industry to focus on production capacity construction, increase production capacity, and deliver more industrial blood. However, with the deepening of exploration and development, the geological targets are becoming more and more complex, and the difficulty of evaluation is also increasing. The rapidly increasing demand for oil and gas drives the pace of oil and gas exploration and development to accelerate, and the contradiction between speed and difficulty will inevitably increase the risk of development. In order to avoid the risks brought by rapid exploration and development, the productivity evaluation of oil a...
