应用新技术搞好温泉井区块断下盘石炭系气藏低渗储量的开发

Application of New Technologies in Developing Fault Footwall Carboniferous Gas Reservoir

温泉井区块断下盘石炭系气藏属于低孔低渗型气藏,它的高效开发具有一定的现实意义。应用精细气藏描述技术开展对构造、储层、流体性质及气水关系、气藏三维地质建模和储量计算等的研究;应用水平井钻井工程技术开展对低渗气藏提高采收率的研究,并对实施情况及效果进行分析评价;应用水平井试油工程技术开展对水平井裸眼分段酸化完井工具配套技术、水平井体积压裂酸化改造技术的试验。分析认为,在温泉井区块断下盘石炭系气藏应用新技术进行低渗储量的开发,使得更多的低效难釆储量得到有效动用,取得了非常好的效果。

Fault footwall carboniferous gas reservoir in Wenquanjing Block is one of low porosity and low permeability.Its high-efficient development is of practical significance.This paper studied its structure,fluid property and gas-water relation,gas reservoir three-dimensional geologic modeling and reserves calculation by applying fine gas reservoir description technology,discussed geosteering tool engineering by applying controlled directional well drilling technology and tested bulk acid fracturing of horizontal wells and other matching technologies by applying horizontal well oil test engineering technology,followed by the conclusion that the application of new technologies in developing hypotonic reserves of fault footwall carboniferous gas reservoir in Wenquanjing Block is successful in effectively employing more reserves which are difficult to develop.
