Title:
INDICATOR DIAGRAM-BASED METHOD AND APPARATUS FOR DETERMINING GAS PRODUCTION AMOUNT OF ROD PUMP WELL
Document Type and Number:
WIPO Patent Application WO/2024/001071
Kind Code:
A1
Abstract:
An indicator diagram-based method and apparatus for determining a gas production amount of a rod pump well. The method comprises: acquiring a wellhead liquid production amount corresponding to each pumping indicator diagram of a rod pump unit (101); obtaining a wellhead gas production amount corresponding to each pumping indicator diagram of a rod pump well according to the wellhead liquid production amounts corresponding to each pumping indicator diagram, and a pre-established model for solving a gas production amount using an indicator diagram of a rod pump well (102), the model for solving a gas production amount using an indicator diagram of a rod pump well being established in advance according to the indicator diagram of the rod pump well and a gas state equation; accumulating wellhead gas production amounts corresponding to each pumping indicator diagram, to obtain a cumulative wellhead gas production amount of the rod pump well (103). The present method and apparatus can quantitatively solve a gas production amount of a rod pump well on the basis of an indicator diagram, thereby reducing labor intensity and improving production efficiency.
