摘要
研究L型水平井的举升系统选型以及排采生产制度的设计,形成举升系统选型的方法,建立排采生产制度的设计模型;以在排采的L型水平井生产工程、煤粉形态为依据,总结L型井各排采举升系统的优劣势;从排采过程管控的重点与难点进行分析,研究L型水平井排采生产制度的动态设计,建立"区块生产制度",单井"差异化生产制度"实现区块产能目标最大化.
Abstract
This study investigates the selection of lifting systems for L-shaped horizontal wells and the de-sign of drainage and production systems.It forms a method for selecting lifting systems and establishes a design model for production systems.Based on the production engineering and coal powder morphology of the L-shaped horizontal wells,it summarizes the advantages and disadvantages of various lifting systems for the L-shaped wells.Through the analysis of the key and difficult points in the process control during drainage and production,it studies the dynamic design of the production system for L-shaped horizontal wells,and establishes"a block production system"to maximize block production capacity by implemen-ting a"differentiated production system"for individual wells.
