气井的产能是气藏工程中的重要参数,是指导气井调配产和编制方案的主要依据。气井产能通常是通过气井试井来完成的,气井试井周期长、成本相对较高。影响气井产能最主要的因素是储层物性及地层压力,储层物性和地层压力的求取相对容易,前人也做过一些利用测井解释的储层物性、地层压力等静态资料预测气井产能的一些研究。预测产能肯定没有试井产能准确,但是预测产能在井网不完善井区,来预测加密产建能力;新井刚测井后预测产能指导后续的产建工作方面具有积极作用,2009年靖边气田产能建设加大了上古气井建产力度,主要利用丛式井来开上古气藏,一个丛式井场有两到四口井组成,井网密度大大增加,井数增多,试气工作量增大。若能利用静态资料来预测气井产能,一方面节省了大量费用、另一方面缩短了建产周期,因此,本文试图研究靖边气田上古气井产能快速预测方法研究,希望能够解决现场问题。
Gas well productivity is an important parameter in gas reservoir engineering and is the main basis for gas production allocation and preparation plan. Gas well productivity is usually achieved through gas well testing, gas well testing cycle length, the cost is relatively high. The most important factor influencing gas well productivity is reservoir physical property and formation pressure. Reservoir property and formation pressure are relatively easy to obtain. Previously, some static data such as reservoir physical properties and formation pressure that are interpreted by well logging have also been used to predict gas well productivity Some research. Predicted production capacity is certainly not well test production capacity is accurate, but the predicted production capacity in the well network is not perfect well area, to predict the capacity of encrypted production; New Well just after logging productivity forecasting follow-up production has a positive role in 2009 Jingbian gas field Capacity building has increased the ancient gas well construction efforts, the main use of cluster wells to open the paleo-gas reservoir, a cluster well field composed of two to four wells, well density increased significantly, the number of wells increased test gas workload Big. If the static data can be used to predict gas well productivity, on the one hand it saves a lot of costs and on the other hand it shortens the construction cycle. Therefore, this paper attempts to study the rapid prediction method of the ancient gas well production capacity in Jingbian Gas Field, hoping to solve the problem in the field.
