Análisis de clasificaciones de pozos de gas y factores que influyen en la productividad en el campo de gas KELA-2
Resumen
Como uno de los principales campos de gas del Proyecto de Transmisión de Gas Oeste-Este de China, la producción acumulada de gas del campo de gas Kela 2 ha superado los 120 mil millones de metros cúbicos desde 2004. Cada pozo de gas muestra diferentes características de producción en la producción de gas, producción de agua y cambio de presión. El avance del agua por adelantado da como resultado una grave invasión de agua no homogénea, y la producción real de gas es mucho menor que la del plan de desarrollo. Para mejorar aún más la recuperación del campo de gas Kela 2, los factores que influyen en la productividad de cada intervalo productivo de gas se analizan utilizando los datos de registro de producción basados en las características geológicas de desarrollo. De acuerdo con el cambio de la producción principal de gas y agua a partir del registro de producción, los pozos de gas se dividen en cuatro tipos y tres patrones de invasión de agua en el campo de gas Kela 2. Las causas del cambio en la producción de gas y la ley de producción de agua se analizan primero para cada tipo y luego se determinan los principales factores que influyen en la productividad de los pozos de gas. Los resultados indican que la caída de presión, la penetración de agua en la capa productiva de gas y las diferentes propiedades del yacimiento son los principales factores que influyen en la productividad. A través de la clasificación de pozos de gas del campo de gas Kela 2, se determinan los factores que influyen en la productividad y la ley de cambio de productividad, lo que podría proporcionar una base para mejorar aún más la recuperación del campo de gas Kela 2.
