Testing method for offshore oil-gas well collaborative decision

Abstract

The invention discloses a testing method for offshore oil-gas well cooperative decision. The test method comprises the following steps: S1, designing a distributed knowledge base; S2, sharing and integrating test data; S3, performing statistics by combining built-in software and system with numerical calculation, and performing cross interchange on a knowledge base and numerical calculation resultdata; S4, establishing a model of the fluid along the wellbore, and establishing mass conservation, momentum conservation and energy conservation models in sequence from the bottom of the well, the seabed, the wellhead and the ground flow; s5, carrying out real-time linkage decision making on oil reservoir geology and test engineering as well as a land base and an offshore site. Whole-course visualization of offshore oil and gas well testing, integration of oil reservoir geology and testing engineering and real-time collaborative decision making of a land base and an offshore site are achieved, and the problems that professional communication is not smooth, and decision making efficiency is low in offshore oil and gas well testing operation decision making over the years are solved.

Description

technical field [0001] The invention relates to the technical field of oil field production, in particular to a test method for collaborative decision-making of offshore oil and gas wells. Background technique [0002] With the continuous advancement of offshore oil and gas well exploration, the water depth of the oilfield area for oil and gas well testing operations is increasing and the operation difficulty is increasing, and the testing cost is increasing day by day. Unobstructed, it is difficult to reach a consensus on the operation in time, and the preparation time for on-site operations is short. When there is a big difference or disagreement with the previous preparation plan, some equipment and tools are dispatched in a hurry, and it is very easy to have insufficient equipment maintenance and frequent operation failures. Condition. [0003] In addition, since the on-site test data cannot be transmitted back to the base in real time, and there is no tracking record a...
