利用水平井技术开发苏里格低孔低渗气藏

苏里格气田是国内最大的气田，勘探始于1999年，探明天然气地质储量5336×10^8m^3，由于该气田具有低压、低丰度、低渗、低产的特点，同时储层埋藏深，制约着该气田的经济有效开发。本文通过对苏H38井的钻完井技术描述，从油藏、工程设计、钻井、完井等方面介绍了该区块水平井钻井工艺，对该区块进一步实施水平井整体开发具有一定的指导意义。

Application of Horizontal Drilling Technology in Development of Sulige Low Porosity and Low Permeability Gas Reservoirs

Sulige gas field is the largest gas field in China. It has been explored since 1999. Proven reserve of natural gas is 5336× 10^8 m^3. The gas field has the characteristics of low pressure, low permeability, low abundance and low formation energy. At the same time, deep buried depth of the reservoir buried deep restricts economic and effective development of gas field. In this article, the horizontal well drilling technology for Su H38 well was discussed from the aspects of reservoir, engineering design, drilling and well completion, which can provide certain guidance to the further implementation of the horizontal well overall development.
